Unable to afford the Panasonic 7-14mm or 12-35mm in the meantime, I purchased the Novoflex Nikon to MFT adapter so I can use my Nikon lenses on EM5. But I've been having a weird issue with either Rokinon 14mm or Novoflex (most likely caused by Rokinon?). On all my other Nikon lenses I tested (Zeiss 21mm, and Nikon 28, 50, 85 and 105), the Novoflex adapter correctly opens and closes the aperture of attached lenses, allowing the control of aperture via aperture ring on the lens itself or using the continuous lever on the Novoflex adapter. However, the Rokinon 14mm doesn't seem to reduce its internal "iris" size past f/5.6 when used with the Novoflex adapter. Basically, setting the Rokinon lens aperture smaller than f/5.6 or turning the aperture lever on Novoflex all the way to smallest position does not reduce the size of the iris that seems to be "stuck" at f/5.6. I wonder if anyone with the Rokinon 35mm and 85mm, or other manual lenses is seeing similar characteristicses. Did I get a bad copy of the Rokinon lens?
