Hello everyone, I'm currently shooting with a Sony NEX-6, and while I love the camera, the lens selection is a bit lacking IMO. I'm considering jumping ship to M43, as there is a vastly superior portfolio of lenses available, and the newer bodies/sensors are very good in quality. Part of my gear for my Sony is the DH-1758 tele-extender that I use on my SEL55210 lens to get me some extra reach (it's a fantastic extender). When looking at the lenses for M43, I plan on going with the 25 f1.4, 12-35 f2.8, and 35-100 f2.8. I feel that with those lenses, I should have a focal length of almost every situation. My biggest issue is that I would only have a reach out to 200mm (in terms of a 35mm equivalent). Looking at the 35-100 f2.8, I see the filter threads are 58mm in diameter, the same diameter as the threads on the DH-1758 extender I have. My question is, has anyone ever used this combination before? Can the extender simply thread right on to the lens? If not, is there something like a 58mm to 58mm "step up" ring (I know it's not a step up, but would allow the extender to be attached to the front of the lens)? Obviously I would run in to vignetting issues on the wide end of the lens, but when at the tele end of the lens, would I have any vignetting? If not, I feel that it would fully round out my kit, as it would give me a 340mm focal length (again, 35mm equivalent), which would be perfect for any occasions I would need extended reach. I appreciate anybody's feedback on this, thank you!
