*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.
I thought that more controlled testing would help clear the air, but alas, no. It just reinforced how difficult it was to manually focus lenses designed for autofocus. Below are the best photos out of dozens of shots.
Canon 50mm f/1.8
Canon 15-85mm f/3.5-5.6 at 50mm f/5
Canon 70-200mm f/4L IS at 70mm
Canon 70-200mm f/4L IS at 200mm
- Shot at a distance of 6ft
- Lens was approx 31 inches off the ground
- On a tripod
- 2 sec timer
- Autofocus set to smallest size
- Aperture was set at the len’s widest setting
- Sharpness set to 3 (default) on Canons and 0 (-2 to 0 to +2) on Fuji
- Exposure was set to Center Weighted on the Canons and Multi on the X-T1
- EV correction was set to 0 on all cameras. I don’t know why the 7D shot everything darker. My guess is to favor retaining highlight detail in RAW.
- Because the Canon has a 1.6 crop factor and Fuji’s has a 1.5 crop factor, this makes the Canon lenses wider on Fuji bodies (which is why the lenses look wider on the Canon body.
- Differences in focus between the Canons appear to be due to depth of field leaning toward the foreground or background.
- Multiple photos were taken to get the best focus. The Canons were often close but out of focus. Fuji was nearly spot on each time.
- I apologize for test 3 images to be so small on the page. I was unable to squeeze 3 images in the narrow WordPress layout without it moving the 3rd image to the next line.
- 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.
