[FUJIFILM X] This $10 adapter opens a whole new world (or rather old world) of lenses to be used on your EF camera. Solidly made and very easy to install... and now you can experiment with numerous vintage eastern European and Japanese lenses. Highly recommended!

[FUJIFILM X] I use a Canon60D in a remote camera trap. I want the (more modern) camera, but not the modern lenses, which tend to respond slowly and lose (focus) settings over time. This adapters allows me to use older, manual, Nikkor lenses in my sets. The apapter is solid metal, and fits both the EOS camera mount and Nikkor lenses well, with no slop, and no excess tightness. Based on experience with first one, bought another for a second camera/lens pair

[FUJIFILM X] Fits nice and tight. I've bought several and had no issues.

[Brass, Metal] muy buen adaptador, construccin slida, buenas terminaciones, agradable al tacto y funcional. Cumple con lo descrito.

[Brass, Metal] As with the safety pin, this excellent adapter is simple but perfect! I so far have made three top-of-my-ability prints on a bottom of the line Swiss-Arca 4x5, using a Canon sensor (approx. 22 x 15 mm). Since the index markings on the face of the adapter presumably are for full frame sensors, I covered them with tape marked in cm and mm. My work flow:Set up the 4x5 as usual for filmRaise the back by less than 22 mmMount the DSLR with the image's long axis verticalExpose a frame, shift the DSLR less than 15 mm, repeat until row is doneLoosen the back and let is slide downExpose along this new rowUse Photoshop to stitch the imagesIssues:I had to remove the focusing glass on my 4x5. The lens-to-sensor distance is longer than it was for film. Consequently, depending on focal length, you may not be able to focus to infinity. Using the thin lens approximation and some reasonable (I hope) assumptions, I computed BALL PARK maximum focusable distances: offset refers to the distance from the (missing) ground glass to the new sensor. Since a camera lens is not a thin lens, these numbers should not be over-interpreted.FOCAL-LENGTH OFFSET FARTHEST-FOCUSmm mm m===================================240 1 58 4 15135 1 19 4 580 1 7 4 2

[Brass, Metal] This adapter fit my Pentax 42mm lens and Canon EOS DSLR perfectly. I was concerned it would not reach infinity since I plan to use the lens for widefield astrophotography it reached infinity perfectly.

[Brass, Metal] I used this to adapt a standard DSLR zoom lens to my Mallincam astronomical video camera for wide FoV use... The build quality is excellent and this will do the trick for many years to come

[Brass, Metal] This adapter is very well made. Perfectly fits the equipment and produces the expected result. Very good purchase. I recommend it to everyone.

[FUJIFILM X] Well made with excellent fit and finish.
Using this to mount an old but expensive microscope lens to a Canon EOS M6. Will allow me to mount old 16mm film camera lenses as well cannot go wrong for the price.

[FUJIFILM X] Use on my old Nikkor lens to mount on EF cameras (Canon 5D, BMPCC 6K, Z Cam E2-F6). Holds the lens tightly, no wiggle, and feels secure.
