Super-Multi-Coated Takumar 6x7 55mm f/3.5
From the mid-seventies, this behemoth might be the heaviest lens I have ever owned. This copy is in mint condition—seriously, it looks like it was never used. The barrel is pristine, and it even came with a skylight filter and a hood. The quality is like other Takumars: all metal and glass, and this one has an enormous front element. It’s a bit of a challenge to focus and to even carry, but the 28mm equivalent focal length is very handy for architecture and landscapes.
