EdMika Launches the FDn to EOS Adaptor

Canon Rumors:
From EdMika
This new EdMika adapter fits many more lenses than previous kits we have made. This conversion kit includes 1x EdMika FDn-EOS-A brass adapter body, 1x EdLink, 1x EdShield and 1x rear EOS cap. You only need to have your own good quality small phillips screwdriver to do the conversion. The main brass adapter body will fit most FDn mount lenses but will not fit any of the older FD lenses that are the silver ring/breech lock mounts. So far I have full kits for the lenses listed in the chart below. These kits allow you to replace the original mount with an EOS mount that will give infinity focus AND will allow you to control the aperture as well. This give you much better image quality compared to the usual FD-EOS adapters available for sale. Those cheap standard adapters use corrective lenses to give infinity focus and with that you lose so much detail as well as a stop of light that it is just not worth using.

If you have Canon FDn mount lenses that are not on this list you will still be able to mount the brass adapter and get infinity focusing on most of them but you would not have aperture control, you would have to shoot wide open only. The FDn 7.5mm Fisheye has a different bolt pattern so I will be making a different adapter for it. I am still working on many more lens kits and plan on having the FDn 50mm 1.2L and FDn 85mm 1.2L kits soon after I develop an EdTraveller to hold the rear aspherical lens element in those lenses. I will also be coming out with kits for the 20-35L and 50-300L zooms and many more as I develop the EdLinks needed to control the aperture. There will not be a kit for the FDn 20mm 2.8 or the FDn 85mm 1.8 since they are missing the holes and screws I normally attach my EdLink to. There is a way to make the 85mm 1.8 work but you would have to get the EdMika kit for the 100mm f/2, grind down the height of the EdLink by about 4mm and find a cheap/broken donor FDn lens and use the grey ring from it instead of the original no hole one in the 85mm 1.8. As always each EdMika adapter comes with the latest Generation 4 Dandelion chip that will come to you preprogrammed with your lens focal length and reporting the maximum aperture. These chips are mostly useful for proper light metering and EXIF data reporting but they are also focus confirmation chips. I recommend using 10x live view for most accurate focus or getting a good focus screen. You can program the chip through your camera and calibrate the focus spot but I find accuracy is so so. 360 Brass was chosen over stainless steel or aluminum because brass is softer than camera and lens flanges ensuring no surface damage yet it is still strong enough to hold on through even heavy abuse. It also allowed us to skip coatings so we could maintain higher tolerances because of the variability of a coating process and because glue holding af-confirm chips bonds well to bare metal but poorly to coatings. Some of these converted lenses come in contact with the thick mirror of the 5D2 and less thick mirror of the 5D3 and a couple contact the 1D4. This does no damage to the lens or mirror (I have hit thousands of times now) and can be overcome by focusing closer, going to live view and then focusing up to infinity. All crop sensor bodies are safe with no mirror hits on any lens at any focus distance. The below chart gives an idea of distances before mirror contact on which lenses and bodies. Some full frame shooters shave the mirror slightly to overcome the contact issue if they don’t want to use the live view workaround. Compatibility Chart | Click for Larger When you purchase this adapter kit you must include a PayPal note with the type of lens from the above list that you want to convert so I can send you the proper EdLink and proper EdShield. If there is no note included I will attempt to contact you through your paypal email address to ask this question again and if I do not get an answer within a day I will Include the EdShield and EdLink that will only work for the FDn 50mm 1.4 lens. If you include more than one lens in the note for a single adapter purchase I will send the parts for only the first one you mention. For now we are not selling extra EdLinks or EdShields separately from adapter bodies. Buy the EdMika FDn to EOS adaptor on eBay

People are still interested in converting FD lenses?  Wow.

The only one that I'd be interested in converting, if I had one, is the 150-600/5.6L, since Canon hasn't decided to keep up with Sigma (or even their older FD selves) in producing zoom superteles, with the maybe-someday exception of the likely-obscenely priced 200-400/4.

DB:
I've looked at getting some FD primes (specifically 55mm f/1.2) as well as some older 135mm f/2 and 200mm f/2.8 lenses on eBay for a fraction of the price of the modern day equivalents.

One issue besides mounting via an adapter is AF lock/confirmation, so I trawled evil-Bay and found this:

I was just wondering whether a separate FD to EF adapter with AF confirm would be better (more usable) than the EdMika kit version?

I'm guessing the difference is in the volume produced/sold.
