I would like to use my grandfather’s Voigtländer Bessamatic lenses (DKL mount) on my Canon EOS 600D.
I looked for adapter rings and basically found two different types: Simple ones without any electronics (from 40€/50 US$), and "AF confirm" types with different levels of complexity (from 60€/75 US$). I also assume there might be different types of chips in the rings (Dandelion, EMF…).
The Voigtländer lenses are 1:3.4/35, 1:4/135, and 1:4/200.
I just started working with a DSLR, and I am a bit overwhelmed with the choices. Should I get a simple one and "learn to shoot manually", or invest a bit more to have the programmable ring with focus confirmation (which I imagine to be pretty cool)?
