Product Photography: Autofocus Helps
Readers know that I strongly favor the Zeiss ZF.2 for Nikon and Zeiss ZE lenses for Canon DSLRs.
Why then do I shoot the Nikon D3s and the Nikon AF-S 60mm f/2.8G for my cycling equipment images (instead of the Zeiss 50mm f/2 or 100mm f/2 Makro-Planars)?
Simple— when feasible, I shoot most of these images at dusk for ideal lighting. I must get them done quickly before the light becomes too dim to shoot handheld (I don’t use a tripod— too slow working). I also like to try a variety of angles and framings quickly, and autofocus makes that approach easier.
The Nikon AF-S 60mm f/2.8G works very well, and offers outstanding sharpness with a flat image field (no field curvature). While it sometimes has difficulty focusing where I’d like, by and large it focuses spot-on with little effort on my part.
