56738Re: [PanoToolsNG] Focal reducer for mirrorless cameras
- Jun 30, 2013Yesss... The metabones and 2 clones. Let's see what they do at the borders. More interesting what they do od a 10.5 nikkor on a Nex, or, better, on a Fuji MX1.2013/7/1 Roger D Williams <roger@...>
Fascinating, Erik. This addresses a real need for extensions to the range and 'reach' of lenses at the wide-angle end for DX and 4/3 lenses. I particularly loved the conversion of a ho-hum F/1.8 50mm lens into a killer F/1.2 35mm lens.
If, as you suggest, it can be used with fisheye lenses I would like to see a DX Samyang 8mm used this way!
