Nikon D700 + Nikkor 28-80mm f/3.3-5.6 G lens. This lens was introduced as the kit lens for the last generation of Nikon consumer cameras which used film. It doesn’t cost much secondhand and it’s very lightweight (and flimsy). The results are better than you have any reason to expect but I have not used it on any camera of more than 12MP and I reckon it would be found wanting on a D800, say. At f/8 it does well on a Nikon D700, but you can’t shoot everything at f/8. What surprises me about this photo of autumn leaves is that it has more quality than I expected for being made at full tele of 80mm with ISO at 2500 and aperture at f/5.6 (f/5.6 is its largest aperture when used at 80mm). The picture doesn’t pop like it might if taken with a prime lens, but - at least on a computer screen - it isn’t bad for general clarity. However, I did give it a bit of Lightroom treatment before posting it here.
Maybe I’m not particularly demanding, having been once a Kodak Instamatic user. After that practically anything looks good (a Zenith EM in my case).
