I shoot with D750’s and just completed calibrations for my 35mm 1.4, 85mm1.4 and my 70-200 2.8. Primes needed calibrations, but 70-200 was almost flat. I do not agree that lenses do not require calibrations, both my D750’s calibrated differently with same lenses being used on both. I calibrated my 70-200 @70 mm focal point. Not cheap glass, but still needed a bit of attention. I would also advise using the software by FoCal...spot on and easy to use.

Been taking pictures for quite sometime now and have progressed through 35mm film to DSLR. Started with D7000, and now own two D750 Nikon’s, and love them. I’m not taking pictures on a full time basis yet, and I still have so much to learn. I’m hoping you folks with the expertise will share some good advice with me on how to become a better photographer.
