Blueberries With a 5d and Mamiya Lens Using Fotodiox

Blueberries - 5d and Mamiya Lens Using Fotodiox Adapter

A few days ago I received my M645 to EOS lens converter. I bought this so that I could use my old Mamiya medium format lenses on my Canon DSLRs (5d series). I went for a Fotodiox converter in the end without the dandelion focus confirmation chip. Apart from this is the cheaper option, I often manually focus with my Canon lenses anyway. Although it should be noted though that modern DSLRs (or at least ones without live view or focus peaking) don’t make this particularly easy.

My first shot with new combination is an image of some blueberries in my garden. As you can see, there is a lovely softness to areas where focus is falling away. It is shot with a Mamiya-Sekor 55mm C wide open at 2.8 on my Canon 5d mk I. I used this camera first because I read that occasional some people have had problems getting the adapters off their cameras. As it happens it came off easily, unlike some reports I had read.

As you’ve probably read, you can only control the shutter speed from your camera; You control the aperture using the ring on the lens. One consequence of this is that you see the aperture changes immediately. It’s like have the depth of field preview on your modern lens pressed continuously. On the plus side you can see exactly what’s in focus. On the negative side as you stop down the image gets darker making it more difficult to manually focus.

So my tip for using this combination in something like “aperture” priority is:

  • Set the camera to manual
  • Get as close to the aperture you want to use while still allowing enough light to focus (so you can assess depth of field)
  • Focus (if you have live view, or a viewfinder with a type of focus peaking all the better)
  • Set the actual shooting aperture on the lens
  • Adjust the shutter speed in camera.camera shutter speed to give the required exposure
  • Take the photo
