Product Name: Sigma retail telephoto zoom lens 50-200mm f3.5-4.5 Canon FD mount *RARE *READ DESC
Rare white body & red ring canon FD lens from Sigma! It functions well, but with some internal oil and dirt in the front elements (can be clean when CLA it), no caps included. NOTE: this lens was having internal haze. It's been fixed now. It was because the glue that used to combine two APO glasses was oxidized. I have cleaned out the degraded glue and applied a new optical UV glue on it and it works fine now. Since I was doing it myself, the image quality might not reach its OEM quality. EDIT: I added a few samples of this lens. Taken with Fujifilm XH-2 + Viltrox 0.71 speed booster + Fotasy EF to FD. I used two adapters and both of them have optical glass. Therefore the optical performance of this lens will be affected. Focus point is on the Portra 160 From pic 4 to pic 7: At 50mm, f3.5 At 50mm, f8 At 200mm, f3.5 At 200mm, retail f8 As you can see the lens flare is a lot at 50 (which has a very vintage look IMO.
