How do ISO settings and quality differ for the Nikon D70, D90, and D7000?
I've had a D70 for a few years now, and it's starting to show it's age a bit, so I'm thinking about upgrading to a newer model in the same line (either a D90 or a D7000).
Two of my major gripes with the D70 were 1) its low maximum ISO setting (1200) and 2) its poor performance at anything above 600 ISO. Just looking at the specs for the D90 and D7000, I can see that they both have a much wider ISO range, but I can't tell if the image quality at high ISOs has improved.
Anyone have any experience with the difference in quality between the D70 and D90? Or a D90 and D7000? More generally--and I know this is entirely subjective--is the difference in quality and features worth the difference in price between the D90 and D7000?
The D70 is no longer sold. The D90, while an excellent camera, is getting a bit old (by digital camera standards). The D7000 is competively priced, taking the position of the D90 in Nikon's lineup.
While it makes very little sense to upgrade a D90 to a D7000, buying a D7000 (after the prices have dropped a bit) is your best choice in this category. Read a review of the D7000 in a recent issue of popular photography.
The d90 will get you a very useable iso 1600. The D7000 gives your improvements in video, some in AF and gives you a very useable iso2000 upto 2500 even.
Even a D90 will already be a massive improvement over your d70
The higher ISO range of the D7000 is well worth the difference in cost IF ISO is important to you. The Sony sensor in the D7000 is excellent.
Have a look at this site, although the D90 is pretty good, you can see the extended range of the D7000.
