This is a spinoff topic from "Are You Sentimental About Your Gear?" Backcountry members like myself have an extensive collection of F-mount lenses. Considering the cost of buying a new Z-mount vs the performance of a similar F series. My thanks in advance for saving me and others bucks, if possible.
Hi Doug, et al… I wanted to respond to your post so I went out this morning (38deg
) w/Z8+FTZii and an old ai-s manual focus lens. I decided on a lens in the middle of my on-hand focal range; the 85mm f/1.4 ai-s. It’s a well built beast

The areas outlined in color were too broad and confusing. I focused the old fashioned way, clarity to my eye….

This is a full frame shot of the marsh grass for my test. It‘s a JPEG large/fine*, no cropping or tinkering with image.

My takeaway from this is that ai-s manual focus lenses are very suitable for landscapes and stationary subjects. Animals, birds, or other moving things will be a big challenge to overcome. The AF (auto focus) lenses from the later SLR and DSLR era are going to be better options…
