FYI: 7Artisans 50/1.1 doesn't focus to Infinity with SL

I mounted the 7Artisans 1.1/50mm on my SL today. It wouldn't focus to infinity. The rear element protrudes back far enough to make contact with the inside of the camera. This caught me by surprise.

I've just done the same. On looking closely the rear element of the lens is slightly unscrewed. Tightening it up made infinity possible but still a bit snug. It's only a fraction of an inch, trying to summon up courage to file the unscrewable casing down a bit. 

Anyone tried this??

I returned mine when I discovered this issue.

A well know issue.
7artisans however promised to modify the lens when I send it back.
The 35 and 28mm 7artisans however have no problems.

Same problem with the 50mm 1,1 with the CL as well

I bought my from 7artisan directly and arrived with modification for my SL.

Worked perfectly. 

This was discussed in one of the thread on the forum.

After careful consideration i have just modified my 7 artisans 50 1.1. It took 5 min, very little chance of damaging the lens.

I filed a chamfer about 15-20 mm long on the edge of the lens barrel at the top and bottom where it contacted the sensor surround. Works a treat

Can you post a photo of your finished lens?

I have a short macro extension ring for the M, so attaching that before the L/M adaptor, then the 1.1 should focus it to infinity.... ???

I just found this topic because I recently bought one of these lenses used, from a private seller. At first I didn’t understand why it didn’t go to infinity on my M camera. Then I put in on my Lumix S5 and the situation was way worse. I think it stopped at something like 5m or so. 

Is there a home made fix and can someone explain to me what to do?

I sent an email to 7A but doubt they will do anything.
