I have the multicoated AI version not the old amber coated non-AI. From what I understand, the later version was noticeably improved when it came to sharpness and especially contrast, due in great measure to the much improved coatings. I really have no gripes about the lens. It is very small and light and works great on the F3HP and even on my D850. When this lens came out, it was somewhat of a novel. But it's focal length range is rather limited by modern standards. I am not a huge range of zooms, preferring to opt for fast primes but if I a just going out walking around Charleston, SC, I will usually take my 24-50mm AIS and 50-135 AIS. If I anticipate I will need something longer, I will take the 50-300 AIS intead of the 50-135mm but it is somewhat bulky and heavy.
