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.
