p.1 #1 · AI Converted 50mm f/1.4 Auto-S?

Hi!

Been using this Pre AI 50mm f/1.4 mounted on my 5Dmk2 or NEX. Early this year, I was able to acquire a Nikon FE2 with a Nikon 35mm ai and a 70-210 ais lenses. Since the 50mm is a pre ai, I didn't bother to mount it on my FE2 nor check if it had been converted to ai.

Last night, I decided to check it after doing some research thinking I might send it for conversion so that I could mount the lens on my FE2 and my coming D600.

I have found that the lens seem to have been AI converted based on some research.

Just to confirm, I attached 2 photos showing the back of the lens (sorry for the quality, shot these with my smartphone).

Just a bit more info, if it wasn't converted, that tab you see that starts at the f8 and goes left towards f16 would be a complete ring around the whole lens.

I have one of these, not converted. I use it on my FE and F3...I've also got an F that I got the lens on, but that doesn't get much use.

Thanks for the info. Will definitely try this on my FE2.

Thanks DABNIK!

Really enjoy using this on my 5d2. Do you happen to know if this conversion was done using the Nikon conversion kit?

:-)

It looks like a legit Nikon parts coversion.

All the homemade attempts look like crap with their paper labels and milled out notches.

It's definitely a factory cvonversion - or at least a factory conversion ring. You can find a lot of pre-Ai lenses on ebay at great prices if you don't mind converting them yourself. I've converted four of them myself, and it's a fairly easy process if you have a set of micro-screwdrivers and a little patience. But before you start buying up pre-Ai lenses, I'd suggest checking Koh's Camera, Crystal Camera Repair, or Pacific Rim Camera for available kits. Each one has a particular number. Then use Roland Vink's site to match them with their corresponding lenses.
