In the previous post, I looked at how the electronic first-curtain shutter (EFCS) in the Nikon Z7 caused exposure differences from the top to the bottom of the frame. A reader pointed out that the optimum electronic first curtain timing depends on the lens exit pupil. I don’t have a lot of lenses that I… [Read More]

I’ve done a lot of work on the way that electronic first curtain shutter (EFCS) works on the Sony a7x cameras, but I never did much with the EFCS in the Nikon Z-series cameras, except to measure how well the did at reducing vibration and the associated image sharpness. The reason was that I somehow… [Read More]

Over on DPR, when I was talking about the noise tests on the D5 and Z7 that I posted the day before yesterday, I remarked that the camera sensitivities appeared to be different, referencing a study I did on the Z5, a7RIII, and D850 some time ago. In that post, I found the D5 to… [Read More]

In the previous post,  I compared the Nikon Z7 and D5 noise under extremely low light conditions. I turned of noise reduction for that series. Now I’ll show you a set of images with LrC default noise reduction. If you look at Bill Claff’s photographic dynamic range numbers, the D5 does better than the Z7… [Read More]

In the previous post, I made a comparison of the Z7 and the D5 in extreme low light. I used AF-S, and the Z7 pictures weren’t a sharp as the D5 ones. So I’m repeating the test using manual focusing. If you look at Bill Claff’s photographic dynamic range numbers, the D5 does better than… [Read More]
