Canon adapter for Fuji X mount – Part 1

Like some of you, I wanted to see if I could use my Canon lenses on my Fuji body. Unfortunately, all the adapters are manual focus only, but for $10, I thought that I would give it a try.

  • The adapter mounted fine.
  • Lenses mounted firmly in place (not wobbly).
  • You can use both EF and EF-S lenses (there isn’t a white dot for the EF-S lenses, but it works if you go between the red dot and the release button).

After extensive testing, I have come to the conclusion that I would pretty much would only use this manual focus adapter.

*Update 9/2015* Hold your horses! Just got a Nikon to Fuji adapter and focusing with an old Nikon lens made in the manual focus age is MUCH easier! Will post more soon.


  • on subjects less than 2-3 feet away (focusing farther is very hard)
  • camera on a tripod (image stabilization is not powered)
  • and on subjects that don’t move (that rules out portraits or outdoors) and can be reshot (that rules out candids)
  • or if I don’t mind shooting multiple shots to get at least one in focus
  • or don’t mind the photo being out of focus

If that fits your bill, great, but this is pretty much the definition of not fun for me. Thank goodness, I only spent $10.

(Using the aperture trick helps, but pretty much eats up all the wonderful bokeh and having the aperture constantly stopped down is a nuisance.)

Why so un-useful?

  • Images with this adapter can be sharp IF you can get the subject in focus. This is a manual focus only adapter, and even with the excellent help of Fuji’s focus peaking assistance, the difference between being in focus and being out of focus is less than 1mm of turn on the focus ring. (Take a moment to let that sink in. Ouch!)
  • Less than 1mm turn of the focus ring would result at the focus being moved 1/4″ – 1/2″ on subjects under 10ft away. That’s easily enough to get an eye in a portrait out of focus.
  • And the big APS-C lenses are freakin’ huge on the tiny Fuji body! Add the adapter and you get this heavy, unbalanced, almost unnatural thing. This combo is pretty much the opposite of why I got a Fuji.

If you are into seeing the test results, here are some images.

Test 1: Initial informal testing

Casual testing of the Canon lenses on the Fuji X-T1 seemed to point to the images being sharper on the Fuji body (which made sense since the Fuji X-Trans sensor does not have an antialiasing filter), but follow-up tests show getting sharp focus is REALLY unreliable (even with the cool focus peaking assistance) for anything past a few feet away.
