Minolta MD Zoom 75-200mm f/4.5

portraits or any tighter compositions I use the very heavy and unwieldy, yet excellent 75-200mm f/4.5. Even slower than the 28mm, which makes focusing a PITA in even remotely lowlight situations, but it makes up for that with pleasant image quality and being very heavy and big.
It's a relative of the manual predecessor of the legendary "Beercan"; it has a very similar optical design, and delivers comparable image quality.
