There's no fast, short tele option in the MFT lineup. Closest thing available is the Leica 45, and that's only available to Jono .
So what are the rest using? Is is working for you? Lets see some of those adapted OM, Pen, Konica, Canon FD, C-mount, Voigtlander, Leica M, Zeiss ZM, and Nikon F lens photos and learn about the options!
If you happen to have the Leica 45 macro :envy:, post some images here as well .
