NEX 7 Review [Part 2]

Hello again, and welcome back! To get to the meat of what most Sony users seem to argue about is the IQ and High ISO Noise generated by the Nex 7 [as compared to the A77], most say that the transparent mirror [pellicle mirror] in the A77 causes a degradation of image quality and 1/3 stop loss [30%] of light creting unwanted noise in the process. With these comparison pictures, you should be able to decide for yourself. You will see three images up to 3200 ISO, its the images coming from my old Konica-Minolta 7D just to compare how an old sensor with a real mirror keeps up with today's sensors and high tech camera's.

Generic settings across all cameras are:
Manual Mode was used
Standard Style with +0 Sharpness, Contrast and Saturation [and KM7D +0 in Hue]
DRO Off [KM7D doesnt have this feature btw]
White Balance using Florescent Warm White [KM7D in Auto WB, I didn't feel like adjusting]
All Camera's are using Jpeg Fine compression
High ISO Noise Reduction is at Low [KM7D only has on and off - set at on]
Long Exposure Noise Reduction is at off [KM7D doesn't have this]
Lens used was 18-55 on all camera bodies @ 35mm range f5.6 all throughout the ISO tests

So the things that only change are the ISO and the Shutter speed which will be captioned in each picture.

NEX 7 Review [Part 1] Updated [Jan 17, 2012]

Coming from a lineage of using SLR type bodies and some 'advanced' compact cameras and bridge camera's I would have to say that the NEX-7 is a very impressive camera with all the bells and whistles of its bigger siblings with a touch bit more than what you could expect in a small package like this.


Up front, is [upon testing] a pretty sharp kit lens with a range of 18-55mm [the equivalent of 27-82.5mm] that matches the Magnesium alloy and high impact plastic body. It has more controls over its predecessor NEX brothers with the introduction of the TRI-Navi system. The two knobs at the back simulate the two control knobs usually found on prosumer models that control different aspects of shooting, couple that with incredible customization and assignment of functions to almost all buttons and you have a very versatile camera at your disposal.


Another thing that sets it apart from its NEX brethren is the presence of several items that make things easier for the more adept shooter as well as a few other highlights.

EVF [Electronic View Finder]
• Eye-level fixed XGA OLED, 1.3 cm (0.5" type) electronic viewfinder
• 2,359,296 dot resolution
• Magnification approx.1.09x
• 100% frame coverage


Think of it as a micronized LCD monitor thats very detailed and fast in updating your view, you get a coverage of 100% which for most manufacturers of Optical View Finders [OVF] usually only have up to 95% and a magnification of les than 1 [typical is .8-.9 magnification]. You can also adjust the diopter [eye correction level] so even without your glasses you should be able to use it. To be fair, the Nex-5n has a similar EVF but is optionally attached to where your flash is usually attached. meaning you wont have the abilty to use your flash if you have your EVF there.

Pardon the quality, I'm not sure how to capture this type of image [eyeview is not vignetting]

  Pop-Up Flash
• Internal manual pop-up flash
• GN : 6 meters
• Coverage : to 18mm
• Flash Sync: 1/160sec

Never forget your flash when it's already in your cam, this little marvel of engineering is pretty neat, it has bends and curves and fits like a jack-in-the-box coming out and going back in. And yeah, it can illuminate your subject too ^__^

It extends on spring loaded hinges, so be careful when its out

iSO/Sony Hotshoe
Its a very welcome addition on the NEX 7 as it will allow the use of more powerful flashes as well as enable the use of the mount for other things that are mountable, like an external microphone. The new hotshoe cover is pretty slick too, looks like a trident, just covering the essentials without being bulky or adding to the height of the camera. Whats showing is the cover partly removed to reveal some of the standard Sony terminals for the flash.

This hotshoe is the TIGHTEST fit on any Sony hotshoe I've tried

In conjunction with this, I'd have to say BE CAREFUL when you use an external flash, I'm pretty sure its the pre-production nature of the camera but the hotshoe fit is very tight and it can be hard to remove anything [flash, hotshoe, microphone etc] you slide into it, be gentle when removing anything attached on top of it just to be sure.

One of the more typical options ported over from prosumer cameras is the AF/MF switch, basically this allows you to change focusing modes from automatic to manual with a press of a button, a pretty useful feature.

Some of the other feature on the camera of note it's is ISO range, on Auto ISO, you can get anything from 100 to 1,600 and user selectable up to 16,000. To the laymen in the crowd, this range means the sensitivity of the camera to light, the higher the number the more sensitive it is but usually at the cost of getting noisy or grainy images. The NEX 7 has little trouble with its range.

SOOC: Straight Out Of Cam 16,000 ISO

You can view the image on my Google Plus page then click on options on the lower left and view image details. It's gonna show some of the exif information and CAMERA: would say "MODEL NAME" since it is a preproduction model, ISO is 16,000, 1/500 shutter speed, f8 and at 45mm range. It was shot on Jpeg Fine with High ISO noise reduction set at low. Pretty decent actually but this image was compressed when uploaded as the file size is significantly smaller, original size was 8megs.

Inside lurks a monster 24 megapixel sensor, the same sensor used on the A77 & A65. And I have to say, it provides this camera with the ability to produce great pictures. You might think you're gonna need high priced Carl Zeiss glass to get the most out of the NEX 7, but even the basic 18-55 can do a great job out of the box.

Here are some sample pics:

ISO 100 f/8 1/500s @ 18mm

ISO 100 f/8 1/500s @ 18mm

ISO 100 f/8 1/500s @ 18mm

ISO 100 f/16 1/125s @ 18mm


Also, given that the image size is greater than most camera's out in the market coupled with the size of the sensor [it's an APS-C or in layman's terms, a pretty large sensor, near the size of a film negative] you can easily get more detail out of your pictures so that if you need to, you could isolate a portion of your image and still be able to use it [somewhat].

ISO 100 f/3.5 1/15s @ 18mm


The scratches and broken parts show easily the age and the wear of years this statue has gone through. Optical Steady Shot [or OSS] helped a lot to get this sharp picture even if the lighting wasn't good for a faster shutter speed.


ISO 1600 f/8 1/40s @ 52mm

People and objects are easily registered on the camera and if you need to...

ISO 1600 f/8 1/40s @ 52mm

You could crop [cut off/isolate] a portion of your very large image to get a smaller image off the main picture like this, this is the above and center relief at the very end of the church. An equivalent of 512mm in lens range! I am quite impressed.

Now for a brief tour of the camera physical stuff via video! NEX-7 Specs are found below the video:

 

Specs can be found on the SONY US site since it's not yet available here in the Philippines yet.

Tonight I should be able to update a comparison between the A77 and the NEX 7 with regards to ISO and a few more details and tidbits about the cam. Stay tuned and thanks for reading ^^

Initial Thoughts with the Nex-7


I got the NEX 7 last night from Sony to review in the next few days and my initial impressions on it are pretty positive: Build is pretty tough and solid, it feels well in your hands, the recessed portion where your hands would typically fall on when holding the camera feels a bit more firm and secure compared to previous NEX bodies. Also the addition of multipurpose function buttons are a welcome treat as with the previous NEX, there are times you would need to dive into the menu system and initiate several button presses before you can get to your desired settings. The built-in EVF helps those who are used to viewfinders and rangefinder type cameras while being a fully featured mini live view, the viewfinder is also an excellent alternative in case the sun is too bright so see the LCD panel on the back as what you can normally see on the back LCD is available on the EVF. Another welcome addition is the presence of a built-in flash and a dedicated flash hotshoe for more flash options.


As an initial impression, the NEX 7 offers tons more than what the previous NEX bodies had to offer, we'll see though if it's something that can match up to Sony's current Semi-Pro/Advanced Hobbyist SLT, the A77. More information, impressions, facts, samples and comparisons in the next few days, stay tuned!

iPad Bluetooth Keyboard

Searching for a way to be productive on your iPad or simply wanting to be able to type that loooooong status update on Facebook or even write up your blog [like this]? Then your next iPurchase should be a Bluetooth keyboard, its not messy [no cables] its [usually] portable, it can be of use for other things that connect via Bluetooth [Android phones, tablets, PS3's come to mind and have been tested on] and its really hand/useful when you really need to type something fast and its gonna be long way to finish.

So now you're wondering, what you can buy to get into gear? Now the Apple Bluetooth keyboard is Php 3,490 and the Belkin I saw at PowerMac was around the same price if a tiny bit cheaper but still over 3k. Knowing this and being on a tight budget, I looked around, there are iPad covers with keyboards costing below 3,000 but above 2,000 and the leather type cases don't really appeal to me, they kinda look er, um, unappealing.

Luckily I was able to spy from CDRKing several Bluetooth keyboards that are affordably cheap. The one I ended up with was CDRKing Bluetooth Keyboard [KL-0042KB], it was [to me] the best buy with regards to size, price and ergonomics.


Specs:
  • Bluetooth V 2.0 with BROADCOM 2042 Chipset
  • 78 Keys design with 13 multi-function keys
  • Scissor-switch keypad design comfortable and ergonomic design
  • Built-in intelligent power management software for power conservation
  • Built-in software solution with Bluetooth human interface device and comply with the standard version of Bluetooth SIG Bluetooth 2.0
  • Powered 2 pcs. AAA battery
  • Working RANGE: 10m

Now to tell you why I felt this was the best, let me make a short run down some things that made me skip these models:

TM-1157: It is small, almost tiny! I don't feel I could type on the thing for prolonged periods of time. It has a built in battery, which with prolonged use could die and is not user replaceable. Php990

K427iB: It's about the same size as your normal keyboard, so its pretty big for an iPad! And also has the same non user replaceable built in battery. Php880

KW-239iB: Now this one is only a little bit larger than the one I chose, and has the same looks with AAA batteries for power [making it easier to replace and if it runs out of power, you just pop in new batteries], now the only thing is, the Bluetooth connection button is recessed, meaning it's not easy to press so you can connect it to a device, this makes it hard to connect to multiple devices on the fly, you're gonna need at least a toothpick. And the last reason is that if you notice, there isnt a power switch, meaning its an 'intelligent' sensing keyboard, though I'm forgetful, I'd rather have the option to turn it off or on at any time. not when the darn thing thinks its best to turn off. Php880

G-K001: Now this is a little bit bigger too than the one I chose and has all the good stuff with it, a physical power switch, an easy to press activation button and AAA battery use. The only reason I didnt choose this is because its bigger [I needed it to be almost the same size as the iPad] and becuase it squarish, it looks like the box type of Bluetooth keyboards [and yes, its just me] ^^ it is a good choice though if you want a bigger keyboard. Php880

TM-1125: Now this case has non user replaceable batteries too but the keyboard is built into the foldable case, something some people may like. I don't since I don't want to bring my keyboard all the time nor do I want it seen all the time with my iPad. It also adds to the width of what you're gonna carry so be prapared if you choose this. The case itself is acceptable, it isn't so tacky to look at. the keyboard is silent and spill proof so that's another thing that's a plus. Overall its a good keyboard case combo IF you're into that thing. Php1,080

KL-0047KB: Now this is about the same size as the iPad, but what turned me off here is that, since I don't have an iShield, placing the iPad on this means I would clamp the front part of the screen and brace the back part of the iPad on this thing, maybe useful if you have an iShield to avoid scratches or possible dents with a silicone/crystal case. One thing though is that its not gonna work with all types of covers/cases. Like my cover would fit and the front bezel protected by the cover but it would be awkward since the cover on mine isn't removable, its just gonna hang there and possibly over weigh towards the back. Another is the non user replacable batteries again, though its supposed to have powr for 55 hours straight [I wont trust that though hehehe] Php1,480

KL-0049KB: Last on the available list so far is this case keyboard combination, again the batteries are non user replaceable, its exactly the same keyboard as the one above. But the case its made of hard plastic and now this case makes it look like your iPad is a laptop. It can be used to hold you laptop in landscape or portrait mode [useful] and closes down on the keyboard like the above case. This means more protection for your ipad but again, it'll make your combination pretty wide :D Some people may like this, but like the same rason above, I skipped this [and its also pretty expensivve, the most expensive they have] Php1,380

Overall, the keyboard I got is [for me] almost just right in the size department, keys spaced enough so I don't over type, its not too big, its portable and ergonomic, roundish, has user replaceable batteries, an easy to turn off/on switch and the Bluetooth activation button is easy to press but not by accident. So if you're on a budget and you like your keyboard separate as an option and want it easy to use and affordable, then this model is for you.

Please note that the selection is for me, is subjective, I am sorry if the descriptions I gave for some of the keyboards are offensive or hurtful but they only reflect my own bias and choices for my own keyboard. Your choices are of course your own and hopefully with some of the descriptions I gave [yes mostly cons], it'll help you decide to buy one of them even if its its not my own personal choice. In an update, i may revise them to add more pro's to help make a better choice, for now though, on with the show! Thank you ^^

Review of the iPad 2 [Coming from a Galaxy Tab user]

Since I gave my Galaxytab to my dad as a Christmas present, I was left without a mobile tablet device for my ebooks, mobile entertainment and connectivity online. I was honestly holding off for the Galaxytab 7.7 [which in all indication is a not gonna show up anytime soon] and the Galaxytab 7.0 Plus is either out of stock or doesn't have installment. So in my mad desperation, I bought an iPad 2 [yeah, Android sell out, bad me].

I had my needs listed in a neat little list:
Must be Android
It's open source, easily customizable, torrents, easy file transfers etc.
7 inches or a little bit more in screen estate
The GT 8.9 might have sufficed but the next need nixed it
if, and its very likely to unify devices, it has 3g/3.5g, it should have phone functionality.
I really hate the idea of having another sim i could have utilized for calls and text, since I am gonna load it at intervals that would accumulate free text for use at least.
And it should have a way to import on the fly
The old Galaxytab [ok I admit this was one of the reasons I was able to let go] did not have the feature to use Samsung's connectivity kit [which looks suspiciously like a black iPad connectivity kit] which allows transfers from an SD card and a USB host connector.

But in the itch for new tech and a replacement for something I can bring along to the bathroom or in my travels, I hurriedly bought an iPad and so far, I'm still mixed but learning to accept it.


For starters, I came from Apple when Apple was just iPods and Macs. My first iPod is still with me, an iPod Video U2 ed, complete with box, manuals, cables and receipt AND it still works :D subsequent Apple purchases included 2 Macbooks, 1 Macbook Pro, iPhone 3g and 3gs but the buck stopped there. After my Macbook died [and later got ressurected] and my other Apple products except the ipod was sold off, I turned my back from jailbreaking Apple products for me and my friends and tried to live a simpler life of a hobbyist photographer.

So what I'm saying is, I'm not NEW to the Apple scene and definitely not unfamiliar with the tech and society involved with it. But even then I chose to go Android, till this pretty little #&^*&&$_&% dropped on my lap. The first thing I noticed [and greatly appreciated] is the screen crispness, with the GT, it felt like reading through a large phone even at 16m pixels and a higher density at that. It isn't really a bad thing up until I got to read on an IPS screen, the clarity, the colors and viewing angles are extraordinary. yeah my sense of wonder never ceases to amaze me [ehem], its one thing when you are testing it, its another when using it frequently. So that chalks up a win there [until the 7.7 with AMOLED comes around that is].

The next thing I noticed is responsiveness, granted the GT had a single core BUT the same RAM and still even at its freshest, the GT can get sluggish and slow to respond. Again, another one for the iPad there. [until yeah yeah, the 7.7 arrives with dual core to go above the iPad specs and Ice Cream Sandwich to sweeten the pot].

Now what I bought for clarity's sake is the iPad 2 16GB without the 3G add on. Why? Cause you can't use it as a phone, there's no way to utilize the free text on the sim or make calls [barring a Jailbreal which isnt around as of this writing]. And if I needed to, I could [and did, get a portable wifi device which can also send text messages if clunky, at least its there as well as share that connection with others] get a device to provide for my internet needs, like a phone or a portable wifi device. Considering the price difference of 7k, the portable wi-fi would make it cheaper or a real phone [like the Sony Ericsson Xperia Mini] which would get me calls and text, as well as an extra device for internet access.

Now for some more good stuff, the connectivity kit for the iPad is better priced than the Samsung one but hard to find [most stores were out of stock], and the fact I use Sony MS Pro Duo cards doesn't help. Luckily I sold off the SD card adaptor and retained the USB for cabled transfers from my A77, yes it works, even at 24mp resolutions the ipad did great in importing them, if a tad bit slow. I also bought a Capdase card reader which included MS support [but you'd need the Duo adaptor to use it, otherwise you'll need a tweezer to take the pro duo card out, I know, I tried :D Sweeter thing is the Capdase has support for SD/HC, MS [and Pro Duo/HX with adapter], mmc, olympus cards, micro SD too! Unfortunately they costs much more than the Apple connectivity kit, expensive living.

The connectivity kit has several advantages over just the card reader, you can technically make tethered shots now because of the 'direct' connection to the camera, you can also use a normal card reader [I rationalize my purchase of the additional card reader as minimizing the connection to the connection to my ipad hehehe] and other usb gadgets tat you might think of, just try it and see if it works.

usb port] is clunky at best, nothing like the almost sophisticated interface provided by apple of opening the photo gallery to import the images AND video then segregate them into imported and last imported photos. Plus, the image you import isn't resized in anyway, there is also at least ONE free Raw conversion app in the store that you could use even with the latest and greatest cameras on the market. If you have the $$$ you could use filterstorm, I heard its a great program to have.

Now with that out of the way, one major gripe is that most of the things I enjoyed free [photography apps, blogging and documents/excel] on the Android platform are paid in the App Store. And I don't intend to get those through illegitimate hacks or jailbroken openings. I'll just have to pay up I guess but it irks me really.

Secondly [and third], the fact I HAVE to use itunes to start using my iPad is another irksome thing, syncing apps, images documents! Also flash, I know millions or maybe at least hundreds of thousands have raised the issue of having no flash support, even if its laggy and a drain on resources, I play some FB games not available in the app store that need flash, even my GT with a 1gh single core at 512mb ram could handle webpages in HD with flash, if quite sluggish but usable. Argh, cant I just frigging drag and drop into the iPad and have my flash and use it? Nope, it'll never happen, sigh.

One other thing is the fact the power requirements for the ipad to charge are pretty darn high, you can barely charge via usb port [same with the GT] but whats concerns me is that the first time I had to charge it from 10% it took nearly half the day to reach 100% but afterwards, around 3-6 hours is fine, slow then quick? crazy charging.

Also, regarding built in Apps, out of the box its pretty darn sparse! yes it doesn't have some of the bloatware apps found in the Android devices of today, but some of those free stuff are actually pretty darn useful, like a simple frigging calculator, yes its pretty weird calculating stuff on an ipad in say a supermarket but I DO use it that way with my tab, grocery list and prices, changes in prices, what I have in stock and need? easily done since the basics are covered, and no ALARM? what the heck is that about? you don't want to tell time with a giant ipod? What the frig is that all about? I had to download 2 non oem apps cause I needed an alarm clock and calculator. Not to mention the free word/excel programs found in Android is paid in the App store [at least the ones apple makes].

Lastly, the most irksome thing associated with an iPurchase is the associated purchase of iParaphenilia - from my capdase denim folio that folds into a movie/photo frame, typing angle and normal cover with magnetic sleep/wake function to of course the camera connectivity kit and the bluetooth keyboard am using now to type :D

Luckily, in the Philippines, the cheapest solution for a bluetooth keyboard is just 880 at cdrking, I got the 990 with aaa batteries for power as opposed to the same priced one with built in batteries. Surprisingly as i was shopping for iGear, the Belkin bluetooth keyboard was priced nearly the same as the apple keyboard with no distinct benefit except its a smidgen smaller. heck the cdrking keyboard is about the same size and way cheaper than the 3k plus price tag of the Belkin, what remains to be seen is how long this thing will last. Thats for another review.

Overall, the iPad is something I feel as a good buy if you need an easy and simple to use, no frills, no need to customize giant ipod and tablet in one and you have money to spare for apps, that is up until you jailbreak the thing and start to tinker with the innards and then really make the most of the hardware which even if technically dated, is pretty darn good. For everything else there's Android and its multitude of iterations, color me rainbow for my love of diversity but that's how it is with me at least.
