ISO quality - 7000 vs. 7100

For those of you who have used or owned both, is the resolution quality on the 7100 one stop better than the 7000? That is to say is an image taken at ISO 3200 on the 7100 roughly the equivalent of one taken at ISO 1600 on the 7000?

No...the advantage (measured) the D7100 has over the D7000 in high ISO noise is only about 0.1 stop.  That said, many prefer the finer grain look of the D7100 noise though...all else being equal.

My opinions are my own and not those of DPR or its administration. They carry no 'special' value (except to me and Lacie of course)

I have no tests that I can give to prove either way. However for my work I'm finding the D7100 more 'usable' in low light situations than my D7000 was. There maybe other factors involved but in museums, where I do a lot of work, I find I can 'push' the D7100 a bit more. Maybe it's just the larger files give me more to work with!

Not a very scientific answer but a hands on observation!!!

Re: ISO quality - 7000 vs. 7100

A good friend of mine is a professional photographer. He shoots weddings, portraits and nightclubs. In addition to his D4 and D800 he used a D7000 for the nightclub work. When the D7100 came out he upgraded the D7000 but found that it performed worse than the D7000 for noise and shadow recovery. He sold it and bought a D7000 again.

I've personally had a D7000 and got rid of it due to the terrible noise performance from 1600 onwards compared to other cameras I had owned. At ISO 1600 onwards it throws in a lot of red and blue dead pixels in to a scene.

I have a D5300 at the moment and find it better than the D7000, although its still not awesome from ISO 1600 on. My money would be that the D7200 will be a pretty solid unit all round so if you can wait, wait. It shouldnt be too far away.

Re: ISO quality - 7000 vs. 7100

Well, I haven't really compared the 7000 to the 7100 scientifically but I've used both extensively. My seat of the pants assessment is that the 7100 is a little noisier in the shadows when viewing 1:1. When downsized for web, they look pretty similar. I don't like going above 800 on either if possible, though, since noise goes up a lot.

Re: ISO quality - 7000 vs. 7100

When speaking strictly about noise, the D7000 performs better than the D7000.

Nevertheless, the D7100's shots are better usable at high ISO, because colors are very much better preserved. Noise can be effectively removed by a software, while nothing will re-create the lost colors.

When I upgraded to a D7100, I started by complaining about a higher noise level. Now I've calmed down and have no worry to shoot at ISO 6400 since after a NR wash and a reasonable resize, the pictures appear almost noise free and full of colors.
