Problem - Nikkor 50mm 1.2 + Canon ef to m43 speedbooster + GH4

Alexandre Desjardins · January 12, 2015

Hi, I just received my metabones speedbooster for the GH4. I thought I would be able to mount my nikkor 50mm 1.2 ais using a fotodiox Nikon to canon passive adapter , but after trying I quickly realized that the aperture indexing post was rubbing against the inside of the speedbooster. I am thinking about grinding it down to make it fit. Does anyone have any experience with this kind of hack or has an opinion on what I should do? Should I maybe just sell the lens and not fiddle around with it?

Thanks

thats is scary. Lucky it did not scrape the speed booster lens. I think the only way to make it work, it to file down that rear part of the lens, until it does not make contact with the adapter.

If you want to mod a 50mm Nikon lens, there's far cheaper alternatives like any of the 50mm f/1.8 or even the 50mm f/1.4 AF-D! Filing down the protruding metal parts will certainly make you lose a lot in possible resale value.

Personally, I'd have a look around for a Canon 50mm f/1.2 and sell the 50mm f/1.2 Nikon. The Canon 50mm f/1.2 performs well, I believe even better than the Nikon (and I'm a Nikon shooter saying this ).
