Which FD-EOS Adapter to Buy

<p>EdMika also has a specific adaptation for the FL 55/1.2 alone. There is also a man in eastern Canada that makes high quality conversions of just about any FD lens to an EF mount for about $200 USD.</p>

<p>Current Adapters We have developed and are selling:<br>

FD to EOS mount TS 35mm 2.8 Tilt Shift<br>

FD to EOS mount 0.5mm dual-orientation adapter for super-telephotos<br>

upcoming adapter kits in order:<br>

relaunch of FL 55mm 1.2 to EOS<br>

FD 55mm 1.2 chrome nose/SSC to EOS<br>

FD 55mm 1.2 Aspherical to EOS<br>

FD 85mm 1.2 Aspherical to EOS<br>

nFD all sub 135mm non L prime lens to EOS universal kit<br>

nFD 14mm2.8/24mm1.4/50mm1.2/85mm 1.2 L to EOS universal kit<br>

FD 35mm f/2 radioactive thorium element to EOS</p>

<p>All will focus to infinity but some will come into contact with 5D/5D2 mirrors near infinity (but not with full frame 1D-s mirrors). For fixed rear elements I am currently developing a two stage floating system. Some of the kits will be a bigger technical challenge to install than my first ones. Jim Buchanan in California has agreed to offer his conversion services and stock my adapters for buyers not up to the challenge.-Ed Mika</p>

<p>Thanks for the news, Ed. What you're doing I find most encouraging.</p>

<p>James, no I just got the plain one. Now that I know how well it works, I'm tempted to get one with a chip, though. Having focus confirmation with my APS-C sized viewfinder and with eyes that are getting kinda old can come in handy nowadays.</p>

<p> </p>

<p>From info picked up elsewhere (an Amazon review to be more precise), the Fotodiox adapters are for crop sensors only. Just as well that I did not try that one, as my DSLR is full frame. My Bower arrived this week (fastest delivery ever from the US - thank you BHP), but no time yet to give it a proper try-out. </p>

<p>If I do get some time, I will try to take some comparative shots using the Bower, the Canon telephoto converter, a cheapo Chinese one I picked up a couple of years ago and my Sony Nex 5. But that is a project for an afternoon when (a) I have run out of work and (b) my wife is not around ...</p>

<p>James, what do you mean "for crop sensors only"? Do you mena to say that they do not fit physically to a full-frame body like the 5D, i.e. that they have rather an EF-S mount than an EF-mount? I did not read such info on the Fotodiox website and after reading Michael's report I was so convinced that I actually did order one from Fotodiox.</p>

<p>what do you mean "for crop sensors only"?</p>

</blockquote>

<p>All that I mean is gleaned from <a href="http://www.amazon.com/review/R1DMB9UJBH013I/ref=cm_cr_pr_viewpnt#R1DMB9UJBH013I">this Amazon review</a>. The reviewer comments:</p>

<blockquote>

<p>The adapter's lens diameter is too small for a full frame camera like the 5D. This leads to vignetting which would be a problem if you try to use the image out to the edge. It was not as noticeable with the 135mm lens as it was with the 50mm or 400mm. Note that this may not be an issue with crop sensor cameras.</p>

</blockquote>

<p>YMMV - I just thought I would pass on what I had found. I expect that the problem, if there is one, will not be with physical fit, just with vignetting.</p>

<p>Thanks for the additional info. Anyway, it's too late to cancel my order so I will just give it a try, though I find your comment contradicting what Michael wrote before which confuses me a bit, since he used the adapter on a 50mm lens and did not report any vignetting.</p>

<p>Not sure it does contradict, fwiiw: Michael was clear that he was using the adaptor on an APS-C camera. If he is using a 50mm lens, by definition he would only be using the central part of the lens's field of view, and so vignetting would be less likely than on a full-frame camera.</p>

<p>James, you might be right, though Michael did not specifically state which camera he was using.</p>

<blockquote>

<p>Michael did not specifically state which camera he was using</p>

</blockquote>

<p>True enough, but see his last post on p. 3 of this thread:</p>

<blockquote>

<p>… my APS-C sized viewfinder …</p>

</blockquote>

<p>I may be wrong, but for me the inference is that his is an APS-C-sized sensor as well.</p>

<p>Yeah, you might be right there. I'll just have to wait and see. The shipping to my place takes about 4 weeks. I'll get back to you all when I have some results.</p>

<p>Guys, sorry for the confusion. Yes, I was using a crop sensor EOS -- an XS (1000D) to be exact. I don't have access to a full frame DSLR, but I do have an EOS Elan IIe, which unfortunately does not have a 100% FF viewfinder, probably around 90% or some such. But that might be good enough. I've never used either of the adapters with my Elan. I don't have access to my gear at the moment, but when I can, I'll report back with my findings. I will state this, though, without measuring each of the adapters' central openings, to me they sure do appear to be very close in diameter. So, chances are if the Fotodiox vignettes, the Bower (and others, like my Hoya-equipped one) probably will too.</p>

<p>Not particularly pleasant news, if this vignetting business is true. I'm hoping to pick up a 5D II soon.</p>

<p>I had a quick go with the Bower on my 1Ds iii plus a 35mm FD and it looked OK. I, too, will have a more considered go and report back.</p>

<p>BTW, I visited Fotodiox's website last night and when you click on "Lens Mount Adapters," the category of adapters that this one was found under is labeled as "35mm Full Frame/APS-C Adapters." I kinda doubt they would indicate this if there were vignetting issues with their adapters on ff cameras.</p>

<p>Hi, in the meantime I got hold of such a Fotodiox FD-EF adapter and tested ist also on an EOS DSLR 1000D. I mounted the new FD 1,2/50mm, the FD 1,8/85mm SSC and the FD 2,8/135mm.<br>

Well, what can I say? The results were rather disappointing, especially with the 1,2/50. The pics with this lens were absolutely useless when used with f/1,2. Towards f/4 they became better. Problem is that the diameter of the back lens element on the 1,2/50 is much larger thatn the diameter of the glkass element in the adapter so that it is no wonder you have to stop down the lens so much until the diameter is at least equal if not smaller as the one of the back lens element of the 1,2/50.<br>

The tests with the 85mm and 135mm lenses were a little more promising but I guess I will resell the adapter again.</p>

<p>ctd. from above. As the software of this forum does not allow multiple uploads from my pc I am sorry not to be able to give you more evidence, but I will try to upload one or two more pics.</p>

I've enjoyed reading these threads a lot.

 

I have an FD 50mm 1:1.8 (I'm not sure what the 1: means), the one that usually accompanied the AE-1 Program, and I've

been thinking of using it in our EOS 70d, just for the fun. I'm thinking of getting one of those adapters in which you remove

the optic, possibly the Fotodiox, but there's one thing worrying me: is there any possibility that the camera may get

damaged? The 70d is crop, so I hope not, but it's something I'd rather not risk just to have fun.

 

Also, has anyone used those adapters with contacts to tell the camera that the lens is MF, so it will beep when something

is focused?
