Can I use adapted lenses on the leica tl2?
I don't cover adapters on cst1 likes cameras, so I can't tell you whether an adapted lens will work well on the Leica TL2. The site's lens list for the TL2 only covers lenses that fit its L-Mount directly.
If you want to stay with native lenses, a few picks from that list suit the TL2's APS-C sensor:
- Leica Summicron-TL 23mm f/2 ASPH: a fast standard-ish prime, about 34mm on full frame.
- Panasonic Lumix S 24mm f/1.8: a light prime, about 36mm on full frame.
- Viltrox AF 16mm f/1.8: a wide prime, about 24mm on full frame.
