FD to EF adapter?

[gm13]

I'm sure there is a thread on these somewhere but searching wasn't helpful.
Who has used them? With or without glass? Without glass there is no infinity focus but what does the range become? I've read that only certain lenses are compatible, is that the case? I'm looking at this guy: http://www.ebay.com/itm/320751417257?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649

Any thoughts appreciated, thanks, Gene

I briefly tested the one with glass a few years ago, not quite sure but I think it doubles your focal length, and not worth it IMO, so many lens can be adapted to EF mount it's not worth the effort to tinker with FD.

I have a 'Lens Doctor' adaptor - manufactured by a very nice guy in Scotland.

Some samples here: http://www.flickr.com/photos/31422927@N04/sets/72157625134696642/

They can be fiddly, to fit and the exposure is definitely not 'point and shoot' but the results can be pretty good.
Best regards,

It doesn't double the focal length, it's more like a 1.25x teleconverter. But the consensus I've seen agrees with yours; unless you have some really, really exotic FD glass to put on it, an FD-EF converter is a waste of time all round. My understanding is that it was made in the first place to give owners of the long super-expensive teles some kind of upgrade path.

Well, I have a 15/2.8, 50/1.4, 35-105/3.5 and an 80-200 f4L for the F1N. I'd like to see how they perform digitally, at $35 not much of a risk really.
I imagine a non glass converter would render better but does anyone know the focal range limitation, if it's not infinity how far out is it?

Perhaps a used Sony Nex 3 with adaptor might be a better bet. More expensive, but more usable.

Hi,

I've got much FD glass and recently bought EF bodies. Bought a glassless adapter, particularly for longer lenses and close up work. Took some time to mount a number of FD lenses on the rig to see what range there was.

The adapter lengthens the flange to film distance, essentially acting as an extension tube. The effect on focusing distance then depends on the focal length of the lens (since the extension of the adapter is constant). The longer the focal length, the farther out you will be able to focus.

Don't have figures or formula at hand, but I doubt you'll get anything w the 15, and only essentially macro with the 50.

Sorry I can't be more specific by lens -- but you'll see after you get your adapter.

Thanks that was helpful. I figured range would be a factor of focal length but didn't realize it was that drastic a reduction with a glassless adapter.
It seems the adapter with an element might be the way to go. I'll post my findings here.

Google search for Ed Mika FD adapter. His adapter seems like the best for FD glass conversion on the market now but it's usually selling so fast. Cheers 🙂
