Advice on Fotodiox Pro Canon EOS to Large Format 4x5 Adapter

[Thib]

Hi guys,
I would like to know if someone has used the Fotodiox Pro Adapter (for Canon or Nikon SLRs) on a 45N-2 Chamonix?
I'd like to get one of these, but want to make sure they are compatible. The description does not include Chamonix cameras but I think there might still be a chance they can work together.
Thanks!

Thib.

Also, for those who tried it, does it really cover the whole 4x5 field?
It seems unlikely since there seems to be only two vertical positions?

I believe the issue that you run into is that the mirror box of the Canon will start to shade the image as you shift, limiting your ability to capture the whole image circle of the lens.

Interesting product. There is one customer review (very positive) on B&H, he does not say which 4x5 he uses.

Also some reviews on Amazon (Nikon version).

The FotodioX site shows the adapter using 6 positions to "cover" the 4x5 frame, presumably with a full frame sensor camera. Of course, if you attach a camera that is not a full frame sensor, you would have a serious problem determining how to overlap the multiple shots you would need to take. Also, the description lists a number of compatible camera types and then adds "with Graflok back" - so not sure if the 4x5 cameras listed all have Graflok backs or not. Sheldon's note about shading caused by the depth of the mirror box could be an issue as well. Would be interested to hear if anyone on the LF forum have tried it.

Hmm, thanks for the input guys.
I would be using it with my Mark3, so full frame it is
However, it seems like there are just two vertical positions (by reversing the whole back apparently), and so it makes me doubt it can actually cover the whole 4x5 frame... I say that because 36mmx2 < 4 inch.

But I would still be interested to know if someone tried one of these adapters on a FF sensor.

BTW, it seems to me that this Shen Hao adapter would be ideal:
Only problem is I cannot find any one selling it. Any idea how to get hold of this baby?

When I looked yesterday on eBay, there were some non-fotodiox adapters (at least one claimed to be Shen Hao, they looked identiical). From looking at them they did not have both horizontal and vertical positions, (just horizontal) and were about $50 less. The more I researched yesterday, the less convinced I was that the entire approach was better than just stitching together images taken with a DSLR. (I also have a FF.)

[Thib]

I could not agree more Paul.
I am not interested in just horizontal movement. If I go for it I want both horizontal and vertical, and also want to have the whole 4x5 frame equivalent.
For horizontal movement alone I can simply use my T/S lens on the FF... Here I'd like to go HUGE, without needing the $$ for a digital back

There are two problems with these types of adapters. First, as already mentioned, is shadowing due to the mirror box. The second is the depth of the adapter + the camera body may make using wide angle lenses problematical or impossible at infinity. Especially extreme wide angle lenses.
