The 35mm T1.5 FD-X lens has been introduced into the TLS range of Canon FD lenses. Although not originally a Canon FD lens, this lens matches remarkably well with the rest of the set. As the fastest 35mm in the FD range is an f2, resulting in a T2.1 rehoused lens, there is need for a faster 35mm for the set to be more consistent. 

After hours of research and working closely with our trusted industry experts, we settled on the Minolta 35mm f1.4 as the suitable donor lens for this project. The lens goes through the same rehousing process as the rest of the FD set, resulting in a lens that matches aesthetically, as well as optically. 

The optical design of this 35mm is more complicated than most of the FD range of lenses. The optical layout consists of a fixed front group with two floating groups internally. The two moving groups inside move at different rates in relation to each other. Being able to utilise our non-linear cam system on this lens was challenging, but ultimately rewarding. This makes the lens fit in with the 'feel' of the rest of the FD range, optically, mechanically and when racking focus.
