Which adapter for Nikon lenses on Canon EOS 5D?
Posted: 21 Jul 2006 at 12:37 GMT

I'm trying to use a Nikon 10.5mm on my EOS 5D and I know Hans Nyberg uses this setup with a DVD Teknik adapter - I tried to order one, but they don't get back to me, so I'm looking for an alternative.
Since the EOS 5D is a full frame camera the mirror is slightly bigger and with certain adapters might get caught on the long metal bit sticking out from the Nikon G-lens. Is anybody using a setup like this that works flawlessly??
Cheers - Christoph

Luca is using the "Pro" model not the "Consumer" model.

Ah yes, that's an interesting test. Also the Fotodiox pro looks like it is a bit thicker, so less chance of the mirror hitting the lens.
And they used the EOS 5D...
Thanks - Christoph

All the EOS-Nikon adapters, should have the same *effective* thickness.
The thickness difference that you see on these pictures is purely cosmetic. The external cylindrical part of the Pro model is really thick but is not functional.
Any adapter must get the lens mounting flange at a fixed and predetermined distance from the sensor plane and as a consequence, also from the camera mounting flange.
Some adapters have a slightly defficient effective thickness and I wrote an article on this subject:

www.16-9.net/lens_tests/15mm_2/sigma1224vnikon15f...
I tried to send a message to the author of the test report and could not get it through
I think that he made a wrong conclusion from its test as the thickness difference of the adapter cannot, in any way, "distort" the focus plane of any lens. It affects focusing distance and only "displaces" the focus plane.
BTW a friend panographer of mine uses a Fotodiox Pro adapter that is very slightly too thin. He did not notice this until he sent me some tests photographs for another purpose. We were puzzled by some "inverse distance fuzziness" and I was able to explain this anomaly much later, only after detailed investigation and tests on other adapters. I then thought back and thought about the -now obvious- analogy.

So what was the end result? Is the Fotodiox Pro Adaptor no good? If so, what is?
Please make it "obvious" what the end conclusion is/was!

OK, I had not read this as I missed the post first time around! So it was too thin "also" did you find an adaptor that was slightly too thick? I would much rather machine one down to size then ad a spacer made or cardboard or whatever. I machine shop with a CNC lathe can handle this with no problem (and at little cost).
I think I will try the "consumer" model as a sample and see what I can get custom made.

Christoph,
Just a suggestion...If you spent all that $$$$ on a Canon EOS 5D, why not just stick with the Canon EF 15mm f/2.8 Fisheye?
It seems like alot of trouble cutting off the lens shade & finding an adapter just to save a few shots.
I've been shooting with the 5D and the EF 15mm and I've been getting incredible results (6 + T + B).
You were looking for alternatives so I thought I might throw something different at you.

I think maybe it's because you can get down to 3 shots with the Nikkor Lens with Canon 5D without the need for nadir and zenith shots.
But I do agree the 15mm lens is very nice and the results are good on the 5D.

Yeah, that's right. I use my Panos for HDR-IBL spheres for Mental Ray, so for every position i need to do at least six brackets, so ideally I would like a two shot solution, but three is alright I guess, but definitely not more. Since I use a lot of the sky reflections I need them to be perfect - the more shots I do, the more the clouds will move and so on...
So I have a Sigma 8mm for one shot skys if necessary and otherwise I can use the 10.5mm for better quality...
Regarding the adapter: I don't quite understand it either, but there seem to be some problems with fisheye lenses. I agree with Michel that theoretically the focus plane shouldn't get distorted, unless: the lens doesn't move as a whole for focussing, but only some internal elements. In that case it could have some negative effect, because for infinity focus the rear element might be in a different distance from the chip as intended by the manufacturer - it'll be in focus, but the image quality will be bad. (hope I make any sense) I don't have the lens with me right now and should have a look at it before brabbling on... The guy from Fotodiox wasn't sure about it and the guy from DVD Teknik neither. Waiting to speak to someone from Novoflex tomorrow...
Cheers - Christoph

Contacted DVD Teknik, Photodiox and Novoflex: Novoflex were the only ones to get back to me with a competent answer, saying yes, there are problems with fisheye lenses and yes the 5D is particularly tricky, but with our adapter and the Nikon 10.5 you won't have any problems.
So I forked out the money for the Novoflex, did my first tests today and on Infinity the lens is perfectly sharp...
The Novoflex is expensive, yes, but very well made, delivers as promised and with very good support, so I feel it was worth the money.
