EDIT: EdMika no longer sells the Brass conversion mount.

Here is a link to the new "Polymer" mount he now uses:
https://photography-on-the.net …showthread.php?​p=16760793


I just finished converting my FDn 50mm 1.4 to an EF mount using the new EdMika Canon FDn-EOS adapter kit. http://www.ebay.ca …1438.l2649#ht_2​239wt_1344 (external link)

He has developed a new line of kits specifically for the Canon FDn (New FD) "bayonet" mount lenses. They don't fit the older Canon FD or FL "breechlock" lenses.

The conversion process is quite easy to do for the average person but you really should watch the how-to video first. http://www.youtube.com …k&feature=playe​r_embedded (external link) The video is 12:21 and that is about how long it took me to do the entire conversion.

This conversion allows full infinity focus without any optics so that image quality is preserved. On a Full-Frame camera there might be mirror interferance with certain lenses at infinity focus. At closer focus distances there is no interferance, and using Liveview eliminates the problem at longer focus distances. Even if you forget and do hit the mirror, it cause no damage to the lens or the mirror. With 1.6 and 1.3 crop cameras the mirror will never hit. (Apparently 1Ds FF cameras have a smaller mirror frame and also have no interference at infinity)

The kit consists of a really nice precision machined brass mount (fitted with a black sleeve to prevent light scattering) and a small machined peice of brass that is used to engage the aperture control after the old mount is removed. The mount comes equipped with a "Dandelion" fully programable Auto-Focus confirmation chip. Also included is a EF lens cap.

Here are some photos of the lens after conversion to the EF mount. There is a small indentation for a "lens Mount Index". (mounting alignment mark). I dabbed a bit of red paint on it so it is easier to spot.

I think this FDn 50mm 1.4 is one of the sharpest lenses ever produced and even wide open at f/1.4 it produces excellent images...........

All wide open at f/1.4

Interesting!

That lens appears to have some vignetting when used on full frame. I don't find it objectionable... actually I think it adds to the images. Have you done some stopped down shots to see if that goes away at smaller apertures?

I saw somewhere that Ed has developed the mount for some other lenses already and is planning to add more, depending upon demant. It will be interesting to see how some of them perform too.

Yes, it definitely has some vignetting wide open at f/1.4 on a FF camera, but it disappears as soon as you stop it down a little.

Nice. Great shots Mike, but the bokeh looks pretty harsh to me (much worse than my EF50/1.4) especially in the fence shot.

The 1D and 1Ds use the same mirror.

Any mirror strike is a function of the mirror return path. I believe the 5D2 was the only one with issues regarding mirror strike and FDn lenses, or at least has the largest swing path of any camera.

Sweet post! Looks great. Wish there were zero mirror issues w/ the 5d2. :(. It's all I shoot with.

Thanks for posting this. I have a 50mm FD lens as well, so now I'm tempted to do this same conversion. Not bad for $140.

Are you sure? Bob Atkins says the 1D and 1Ds series use different size mirrors: http://www.bobatkins.c​om …n_eos_1D_MkIV_r​eview.html (external link)

1D series use an APS-H format sensor (28.1x18.7mm), which is larger than APS-C and so can yield higher image quality, but is smaller than full frame, which means that the file size is smaller and the reflex mirror can be smaller and lighter. This enables the camera can operate at higher speeds (10 frames per sec).

With the 55 1.2 aspherical its only a problem at 30 ft - infinity and no problem at all if you use live view.

Allelujah! someone using the word correctly (a quality of out-of-focus detail) rather than used to refer to out-of-focus detail. :)
