I have a D7100. It is a good camera, but like all 24MP sensors, on APS-C, noisy above 400, losing resolution to noise.
So it sits in its case and I dont use it.
I did not realize why until too late, having loadsa full-frame lenses.
Nikon do not produce a 16-50mm F2.8 lens is why. Imagine a D800 without a 24-70mm f2.8?
Can’t, can you?
Well, thats what an APS-C Nikon or Canon is. How it is that only Sony has a 16-50mm f2.8 lens I just cannot imagine, but I am sure not interested in a Sigma 17-50mm f2.8 because the last one I tried was not sharp, no.Its Nikon’s JOB to produce one- and 16-50mm f2.8. Sony can, yep!
And the 17-55 f2.8 lens Nikon should have discontinued when they brought out the d200 because it has less than 10MP resolution and costs £1000+ AND is VERY heavy is no go, because its not sharp, period, and not wide enough anyway.

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
