I‘ve been using the Really Right Stuff NEX-7 baseplate for a few days. I can recommend it, with one caveat. The first thing you should ask yourself is, “Do I really want to use this camera on a tripod?” The answer could well be no; one of the great arguments for the camera is its… [Read More]
Noise vs resolution — part 8
In this post, I compare the Sony NEX-7 with the Nikon D3s operated in full-frame mode, with the Sony images resized to the Nikon’s 12 megapixels. I used the Nikkor 35mm f/2 D on the NEX-7, and the Nikkor 50mm f/1.4 G on the D3s, providing approximately the same angle of view. The NEX-7 did… [Read More]

Noise vs resolution — part 6
Why does the technique of the previous post work? I think it may be a combination of the following: I didn’t use liveview to focus the D3s reference image, so it could be slightly less well focused than the Sony images. I will use liveview in future testing, although it increases noise by heating the… [Read More]
Noise vs resolution — part 5
I have exciting news. At least, it’s exciting to me. Your reaction may be, “Kasson, you really need to get out more.” Anyway, after many unsuccessful attempts, detailed in the previous posts, to tame the NEX-7 high-ISO noise by reducing the resolution of the image, I finally found something that works. Here’s the recipe. Go… [Read More]
