Hello there

I just received a TTArtisant 40mm macro for my Fuji XM-1, much needed to scan negatives.

The focus ring is slow and need quite some efforts to turn. Probably best for precision and not sliding out of focus.

But the mount has a quite a lot of play. It rotates following the focus ring adjustments, which, in turn, mess with the focus… It fit nicely flat on the body but this angular free play is annoying.

Anyway I need a macro lens, and can’t afford $600 for a genuine Fujinon X mount Lens…

Does anyone also have TTArtisan manual focus lenses ? How does they fit ?

I am tempted to send it back, can’t decide. Any advices ?

Bye

[Edit] thanks for all replies, the lens is sent back.

[Edit] new lens came in, with exact same angular play. I guess it's my life now, I shall keep it.

Are you using something to hold your camera, like a tripod, and some kind of jig/fixture to hold the film in place? Ideally you wouldn't need to touch the camera and the film would be positioned consistently between shots. Without some kind of setup scanning will be very fiddly as you need to be perfectly centered/squared/etc.

Could the camera possibly be moving some between shots? Are you shooting wide open?

As for focus changing with lens rotation, that would indicate something in your lens lacking axial symmetry. An uncentered/decentered element, an element that's not ground just so, etc.

I use a sturdy tripod, the camera doesn’t move or drift between takes.

The lens is set to f5.6 as a rather delicate balancing between the light source, shutter speed and ISO settings. I would prefer f8 but it is not ok

I do hit the camera with my arms and hands from time to time, then I redo the focus but that is on me.
