I have the RainbowImaging M42 Adapter, which works great and not expensive. This lens is wonderfully sharp and its weight helps me keep steady. Haven't tested the bokeh yet. I prefer an EVF when using MF lenses as focusing becomes more critical the longer the lens.Hi Simonz,
Wich adapter do you own ? I have an Helios 44M 58 too from a Zenit camera and I would like to try if I buy a GF3. And what do you think of the result (sharpness, bokeh) and the method to focus ?
