Digital SLR wisdom?  
Nikon has decided that they're current generation of digital SLRs will stop having support for auto focus in their old lenses, except in the higher end (and therefor out of my budget.) So I've been looking at the last generation on ebay, which is both more affordable and still has support for my two old nikor film camera lens auto focus (this is why I'm looking at nikon, so I can reuse my nice, '92 telephoto lens.) The problem is they made a firmwear change that makes a noticable difference in picture quality.

So I pose this question to digital SLR users (and to anyone who wants to take a guess at it): How often do little compression artifacts bug you in your pictures or do you never notice? Or do you just have enough enough camera that you can't notice?

If you want to see what I'm talking about, this page has a comparison between the d40 (the current generation) and the d50 (previous generation.) You can see the problem the worst in the vermouth label.

I'm just wondering if it will bug me enough that I will feel I've made a bad purchase.

I can notice particularly egregious compression artifacts, but nothing in those pictures (or anything I take myself) ever bugs me. In general I tend to shoot at my camera's maximum resolution with minimum compression but still in JPEG (not raw) mode, memory cards were cheap two years ago and aren't getting any more expensive. 300 pictures on a card wasn't enough to get me through two weeks in Switzerland but it's more than enough for almost everything else I've done.

I agree with dzm. You will not notice the compression artifacts in practice. Flash is really cheap these days, get a big card and use the highest quality compression. Or if you really want (though probably more for the extra dynamic range, on either camera, than for the difference in compression) shoot RAW and use photoshop to encode however you want.

I have a D70, which is probably very similar in all these respects to the D50, and love it. I don't feel any need to upgrade in the foreseeable future. Get the D50 and don't look back.

I notice oversharpening far more often than compression artifacts. I see compression artifacts on random stuff on the internet not infrequently, but it's never been an issue on my own camera, whereas I do get annoyed by the oversharpening if my cameras settings get returned to default.

I found it educational to skim though dpchallenge.com; after a bit, I could tell at a glance when the first five comments would be "oversharpened".

Ditto what they said, for my D70.
