Canon LTM Lenses for Leica Cameras
This post and embedded YouTube video introduces the concept of using vintage Canon LTM lenses on Leica cameras. The video includes the Canon 50mm f1.8 LTM, Canon 35mm f1.8 LTM, Canon 28mm f2.8 LTM and Canon 50mm f1.4 LTM. Leica cameras featured iinclude a vintage Leica iiia, Leica M3, Leica M6 and Leica CL mirrorless camera. The video explains what lens adapters you need to mount LTM lenses on a Leica M camera. You can also mount LTM lenses on Sony, Fuji and Micro 4/3 cameras. I use the LTM lenses on my Lumix GH5 M4/3 camera.
My appreciation of LTM cameras started when I bought my 1930s Leica iiia. Other examples of cameras which I own with the Leica screw mount include Leica iiig , FED2, Zorki C and Nicca iiis. There is also the more modern Voigtlander Bessa L with the same LTM mount.
Leica Thread Mount (“LTM” Mount)
For those that are not aware of the term LTM it stands for Leica Thread Mount. To confuse thinks further it is also called Leica screw mount, L39 mount and in terms of screw thread diameter M39 mount too.
Vintage Canon LTM lenses
The vintage Canon LTM lenses date back from the 1950s where the cameras they were designed for had the LTM mount. At that time many cameras used the same mount and not only Leica despite the LTM name. These means there were many lenses made with the Leica screw thread design. Canon LTM glass is among some of the best from that period. The sharpness of some Japanese lenses from the 1950s out performed some Leica lenses of that era. The Canon 50 f1.8 LTM is much sharpen than my Leica Summitar 5cm f2 LTM for example (wide open).
What Canon LTM lenses I use

LTM lens adapters (LTM to Leica M adapter + Others)
Part of the Canon LTM lens video explains what LTM lens adapter you need to mount a LTM lens on a Leica M camera body. You need to be careful to buy the correct adapter for the lens focal length you will use. The adapter for a 35mm LTM lens is different to the adapter needed for a 50mm LTM lens. This is because these vintage LTM lenses do no trigger frame lines in a Leica M camera. You need to buy the respective LTM adapter to activate the framelines you want to see in the Leica M viewfinder. These LTM adapters normally give a pair of framelines.
There are 3 LTM adapter versions available:
- 28mm/ 90mm framelines
- 35mm/ 135mm framelines
- 50mm/ 75mm framelines

LTM lenses on Sony, Fuji, Micro 4/3
You can also mount LTM lenses on Sony, Fuji and Micro 4/3 cameras (via an adapter). The video features the LTM adapter I use to mount Canon LTM lenses on my Lumix GH5 M4/3 camera. Some of my previous YouTube videos were recorded with the Canon 50mm f1.4 LTM.
