This has been a boon to my Macro Shooting. It allows for absolutely startling Focus Stacking. Given that manual focus is the best option for macro shooting most of the time and even if it wasn’t necessarily the best way to go, I’d rather not use the auto focus with my Nikon 200mm F4 Micro. My one criticism of the lens is that the toggle for the manual / autofocus is fragile and the only real plastic on the lens. Others have commented that over time this is a potential failure point. I’d prefer to not use this particular component of the lens at all. I like to leave it set on Manual and not change it at all. There’s really no need given that the Lens was bought specifically because it’s the best Macro Lens Nikon offer at this stage short of Microscopic Technology.
