NEX 7 Review [Part 3] In Use Review

Am back, had some trouble along the way to writing this but it's something I endeavor to finish. Anyhow, from my experience with the Nex-7 [Pre-Production] unit, its relatively easy to learn how to use it just using the default settings and button layouts though coming from a full bodied aps-c camera system, it can be a little bit confusing at first. What the Nex-7 has achieved though is a simplistic way of portraying camera functions and features so you can easily understand it if you read the displays, after awhile though the default button layout can be easily used without much thought or looking at them.

Standard settings can be used for quick moment to moment snaps so you wont be able to miss out on a moment as the shutter to shot time is pretty quick, faster than my A77 and even if its just contrast detection, it can focus fast with adequate light.


The image above was supposed to have been a picture of the tableau but when my other eye saw the kid shushing her mom, I zoomed out and refocused and was able to get this shot. For street style photographers, the compact size makes it a little bit more unobtrusive and the quick  accurate system helps a lot to get some good shots.



 For travellers, the compact nature of the Nex-7 would allow easy carrying and good automatic controls.



If you play around with the controls and try more settings like aperture priority, you can get really sharp images and good control over a scene.



One of the biggest advantage of the Nex-7 is it has a Sony hotshoe, this allows versatility in the studio using standard Sony compatible radio and flash systems. One caveat though is that the onboard flash is unable to wirelessly trigger flashes [except of course slaves] and would need an F20AM, F43AM or F58AM to be able to command flashes. This might be a firmware issue since its a preproduction model though.




The Nex-7 also has a lot of fun stuff up its sleeve which can also help you get creative shots. The one's I used a lot are those that aren't easy to reproduce after a shot is made. Partial Color is one of them and it makes thing stand out amongst the crowd. You can select from Green, Blue, Red and Yellow.


Another is HDR Painting, which basically merges together 3 images shot in succession with low, standard and high exposures to produce an image with a blended look that's [ideally] evenly exposed in all areas and its kinda hard to duplicate on a computer.


Now the best feature the new SLT's and NEX camera's offer is sweep panorama, yes you cant manually sweep panorama yet [who knows eh?] but even on camera controlled settings sweeping your camera and getting a wide view image is easy, like really easy! But with the Nex-7 its even easier, yeah, hard to top really, the control dial allows you to choose the direction of the panorama with the turn of a dial. Going left, right, up or down, wide or standard, its way easy with the Nex-7. With the A77 you'd have to turn the dial to Sweep Panorama then dive into the menu to choose the direction and length of the panorama, I hope this feature for control gets ported to the slts.






I so obviously love this feature, when using the wide and downward/upward panorama, it allows you to have images similar to those taken with an ultrawide lens, talk about lens savings :D

The last feature that most people want to know about is video, since the preproduction model only has one mode at 1440x1080, its the only one I could test. It works as described, similar to the the A77 video output but what makes this beauty shine is that with the tri-navi system, you can easily control aperture, shutter and even exposure compensation while enjoying full contrast autofocus. There are three samples I tried with no tripod to see how the Nex-7 can deal with my shakey hands.

 

This is a simple panning shot and it seems alright, the optical stabilization seems to be doing its job well.


Here is when you ride a tricycle on a rather bumpy road, if you ever wanted to emulate the Blairwitch project, yes, you can with the Nex-7 hehehe.


Last is a standing still shoot to see how sun and bright white clothes are dealt with by the camera, I'd say pretty good!

In conclusion, the Nex-7 presents itself as a big leap in terms of user controls and image quality over the previous Nex systems. I argue that even if its a 24MP camera with probably smaller pixels for getting image data, Sony was able to put together this beast of a camera and make it work incredibly well. It's low light capture abilities are good that you can have usable pictures even at maximum 16,000 ISO. Its additional features makes it on par with regards to existing gear [like flashes] and usability with the tri-navi control system.

 Now with the good always comes some kind of compromise, though the body feels solid, for bigger hands, it may not feel all that comfortable at first, you'll get used to using it though bu either cramming your fingers in the grip, wag your pinky up in the air or support the base by curling your pinky under it. Another thing that was a bit of trouble, using the flexible spot [local for slt users] you'd need to press the focus type and select the flexible option then move the focus area to where you want it to be when taking stills. To me that's a slight disadvantage in speed and control. Last is the the lack of certain plugs/features like a remote or pc sync plug for studio use.

Other than that, those, the camera is a great thing to use and own and I would heartily recommend it to people who would like a light and easy to use camera for casual to intermediate users as it would help them get the best pictures and video while giving them great spaces to learn and improve. For those already on the advance level of skill and gear, the Nex-7 can present itself as a second camera and a great travel companion and backup camera. With its ability to do video and control it well, it will be a great for those wanting to focus on video but still want a great camera for stills. overall, if I did not have my A77 I might have chosen this instead.

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.

Sony's 1/20 Secs KM7D 1/15s [Click to enlarge + right click view for bigger]
Both 1/40 Secs [Click to enlarge + right click view for bigger]
Both 1/80 Secs [Click to enlarge + right click view for bigger]
Both 1/125 Secs [Click to enlarge + right click view for bigger]
For now, I leave you with these pictures, you can decide for yourself regarding IQ and Noise. Will be updating this later when I wake up, for now, good night guys ^^

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!
