These two adapters together, I use to mount my Jupiter, Russar and Orion lenses from 20mm, 28mm, 35mm and 50mm to a Sony A7s. The 28mm and 50mm I can also adapt to my gh5 and gh5s, but the 20mm and the 35mm have too protruding of elements to exist through the gate to the sensor. I also have one of these for Canon RF and Micro 4/3. You may request those through this listing if you like. Cameras that are compatible with this (or the RF / micro 4/3) adapter include: Sony FS7 ($99) - https://www.sharegrid.com/losangeles/l/100889?type=rent Sony A7s III ($89) - https://www.sharegrid.com/losangeles/l/184084?type=rent Sony A7s II ($65) - https://www.sharegrid.com/losangeles/l/83569?type=rent Sony A7s ($29) - https://www.sharegrid.com/losangeles/l/95227?type=rent Red Komodo 6K ($195) - https://www.sharegrid.com/losangeles/l/186054?type=rent Canon R5 8K ($95) - https://www.sharegrid.com/losangeles/l/184102?type=rent Panasonic GH5 ($49) - https://www.sharegrid.com/losangeles/l/83573?type=rent Panasonic GH5S ($69) - https://www.sharegrid.com/losangeles/l/100657?type=rent Here's a lens set that these adapters will work with: Three (rangefinder) lenses ($40) - https://www.sharegrid.com/losangeles/l/134312?type=rent Other Leica M Adapters include: EF Lens to Leica M Mount (Non-Electronic) ($7) - https://www.sharegrid.com/losangeles/l/139026?type=rent Other Sony NEX Adapters include: PL Lens to Sony NEX Mount ($19) - https://www.sharegrid.com/losangeles/l/126085?type=rent EF Lens to Sony NEX Mount (Non-Electronic / Electronic) ($5 / $25) - https://www.sharegrid.com/losangeles/l/144787?type=rent Micro 4/3 Lens to Sony NEX Mount (Non-Electronic) ($7) - https://www.sharegrid.com/losangeles/l/144799?type=rent Sony NEX Lens to Nikon Z Mount (Non-Electronic) ($10) - https://www.sharegrid.com/losangeles/l/160760?type=rent The Leica M to Sony E adapter is a close focus adapter, it moves the lens forward and back, shifting focus closer as it's done so!! So this adapter serves a dual purpose. - $10 The Leica 39-Leica M adapter I will rent for $5 individually. The close focus adapter is quite useful. It makes all of these lenses macro lenses. It requires a Leica 39 - Leica M adapter and then the Close Focus Leica M to Sony-E Mount. The other lenses can be adapted from EF to Leica M (which is included) so that you can use all the lenses with the close focus adapter. And that would definitely be useful. Once you get to the 180mm you would have to support the lens because of the weight.*
