The User's Rewivw: Sun Opt. 38-90mm 3.5 Macro Zoom Lens, with 5 turning rings
This lens catches my eyes with its five (5) turning rings on its barrel, probably the lens with the most rings I have ever seen. The focus and macro rings, but not the zoom ring, change the lens length when turned while only the macro ring when turned moves the rear element. The highest macro rate is 1:4 on this lens.
There is a hood (67mm) on the lens as showed in the last image. However, I am not sure if the hood is original.
