It's been a long, long while since Nikon's full-frame stable saw a refresh, but the company's been keeping it clicking down at the low and mid-range. Take the D5100, for example -- for $900, it offers up a fairly stout set of specifications, but as with everything else, we're certain those that bought in have a thing or two to say after a summer's worth of shooting. So, let's have it! Are you satisfied with the quality of the 1080p movie mode? How's that low-light performance? Is the construction solid enough for your clumsy hands? Are you feeling the burn with no built-in AF motor? Go on and nitpick in comments below -- mama always said her kids deserved to be heard.
