FotodioxAdapter - M39/L39 to Canon EOS (EF, EF-S) - Black Metal All-Metal Design - Manual Aperture Control

This is an excellently engineered adapter allowing Mamiya 645 lenses to be used on Canon cameras. There is no electronic connection between the camera and the lens so it has to used in the manual mode. The lens fits into the adapter and the adapter to the lens with no free play or tightness, it is an example of precision machining.Once fitted, set the camera to manual exposure and set the exposure using either a light meter or the camera's own exposure system. Focusing is best done a full aperture but cameras no longer have microprism or split image finders to assist. On cameras such as Canon, Nikon, etc. with the image stabilisation built into the lens this is lost.As to the performance of the lenses when used this is down to the specification of the Mamiya lenses. Tested against modern Canon lenses the old Mamiya lenses perform no better than Canon's latest offerings. However, the edge definition is superb as you are now using on the small centre area of a lens that was made for a much larger negative.Use this adapter with Mamiya lenses for portrait and landscape work and the combination is excellent. For action photography keep with the automatic lenses but this is not a failing of the adapter.

I used the adapter for the first time today in Newcastle. The images taken using both a Mamiya 80mm and 150mm C lens attached to my Eos 5d are superb. The sharpness and colours are absolute top drawer. I now have two additional prime lenses in my arsenal and at a fraction of the cost of a Canon or Sigma offering. Would heartily recommend.

This is a well-engineered piece of kit, holding the heavy Mamiya 645 lenses and/or Bellows to the Canon EOS mount - there is no play at all.BUT this is a waste of money (the same applies to the Fotodiox Tamron-EOS Adapter) for anyone with a Canon EOS 1DsMkII, which is my camera. The mount touches on an internal switch which tells the camera to interrogate the lens for its settings. As a consequence, when you press the shutter button, the camera is expecting data and when none are forthcoming, it locks (Error Code 01 shows) and only a second press of the shutter button clears the camera. Fotodiox states that this and the Tamron adapter are compatible with the 1DsMkII - this is not true. It works superbly with most Canon DSLRs but NOT the 1DsMkII! I now have a lovely, well-machined paperweight plus another for the Tamron-EOS adapter.Provided you don't need to use the adapter on my camera model, I can heartily recommend this product. Fotodiox should take note that their info is wrong.

I bought this to fit the excellent Mamiya 645 50mm. shift to my 5D Mk II. It was remarkably inexpensive (around £35) considering that this is the higher quality Pro version and the quality of the lens makes it well worth the price for architecture and pan-stitching.

Just the thing. Arrived when promised and did the job perfectly.

Good quality works great

I recently purchased this adapter to fit my mamiya 210mm f4 N lens on my 550D body. the quality is remarkable and easy to use. it just did not focused on infinity in conjuction with the hard stop and seemed to be some mm behind infinity mark.I decided to keep it and see how can i utilize this with other bodies. I would prefer the af confirm chip version, after i experience difficulties with focusing, as the focusing is much better in F4 and then stop down which makes image darker and more grainy, making focusing a hard job for me especially if shooting handheld.It has no play on 550D.

Superb. Old Mamiya lenses live again.

Great product five stars

My lens is essentially macro because the flange distance isnt correct...

Ｌ３９レンズをEOSで接写に使うのを楽しみたい

Works as advertised however there’s a couple of issues;1. A bit of free play when mounted to my camera, not that much of an issue normally, but Mamiya lenses are quite heavy compared to normal 35mm lenses2. Ridiculously hard to remove my mamiya lenses once it’s adapted to it, like seriously I had to use gloves to remove it. I’m not sure if it’s an issue with my copy as the latch button doesn’t seem to work properly.Given that it’s one of the few m645 adapters in the market and the low cost of it, I can’t complain much but at the same time I’m not sure if I trust to leave my mamiya lenses on it for too long.

exellent
