You are right, Andrew. I have updated the specs. Thank you!

Evgenii, a minor spec correction: this lens appears to have 9 aperture blades rather than 8. I know one of the few reviews online says 8, but after close inspection, my copy has 9 blades (they’re so tiny it’s hard to tell without zooming in on an iPhone photo). I’ve got the later version with the (C) for coated, and the dual aperture scales, one on each side of the lens. Cheers!

You don’t have another lens on the list. This is a Sigma zoom Auto Focus 21-35mm f/3.5-4.2 Multi-Coated . 1987 ?

i use mine on the Z50 and Z6. for the z50 i had to go into tools and change autofocus adjustment to -5. works good now. of course i had to use the FTZ adapter. made in thailand.

under rated lens. sharp, high contrast images. very compact & light weight. only con is wide open aperture range, strictly daylight.outstanding on small mirror-less cameras. accept no substitutes.

this is positively one of the best lenses i own. super sharp. if you want a vintage macro get this one. good working distance for insects.

much smaller & lighter than f/1.2’s. not much bigger than f/2 or 1.8. excellent wide open. with a lens hood it is just as good as the best 50’s stopped down. get one!

this is a zoom lens you can leave on yer camera all the time. sharp across zoom range even wide open. it’s big though and heavy. if you want to get one vintage lens, this is it. has a macro mode at wide end.
