Laowa 25mm Ultra Macro (Canon mount)

I bought the Canon mount plus the Canon EF lens to Fujifilm X mount camera adapter for use with my Canon EOS 5D Mark II DSLR and Fujifilm X-Series mirrorless digital cameras.

My Canon 5DM2 features a “full-frame” digital sensor; both my Fujifilm X-T1 and X-T3 cameras feature an APS-C digital sensor.

The following photo is an un-cropped, full size image from the full-frame digital sensor in my Canon 5DM2. Notice how much smaller the subject appears to be in this photo, in contrast with one of the un-cropped, full size images of the same specimen taken with my Fujifilm X-T1.

The Fujifilm X-T1 has a crop factor of 1.5x. In addition, the Canon-to-Fujifilm adapter (~1.25″ thick) increases magnification like the net effect of adding one or more extension tubes between the lens and focal plane of the digital image sensor.

The same photo was rotated slightly and cropped for better composition. Pretty good for a one-off shot at an aperture of f/8! Or was it f/5.6? I can’t remember and the EXIF info says f/0 because there aren’t any electronic contacts between the lens and camera body, so no help there.

    I clicked on the shot to look more closely at it and the detail is simply amazing, although, of course, the depth of field is pretty shallow.
