spydrxx Posted November 3, 2023 Share #21 Â Posted November 3, 2023 Advertisement (gone after registration) You're very lucky. I'd strongly urge you to carefully check any strap before going out with it. A couple of years ago I had a leather one on my Nikon F5 break, and it was pretty costly to repair the damaged mirror box. Thank goodness the lens was ok. Since then I've been very careful to check whatever strap I'm using before going out...especially leather ones. Old leather deteriorates, so I've egun replacing old ones with new leather which I've sized, cut and prepared myself. Link to post Share on other sites More sharing options...

Old leather deteriorates, so I've egun replacing old ones with new leather which I've sized, cut and prepared myself. I was an hour into my shoot when it happened.  As you can see in the photo if the strap moves up at all, the pin in the buckle will not hold the leather tight. This now opens the buckle and the strap lets go. I am going to put a pop rivet into the strap, at the buckle, which will stop it opening, permanently.  I love the strap but it is a design flaw. Or to put a positive spin on it, an opportunity to improve the strap!     Welcome, dear visitor!

jto555 Posted November 13, 2023 Author Share #23 Â Posted November 13, 2023 Just a final wrap-up. The mount arrived today in the post from TTArtisan and is already on the lens. I readjusted the focusing and the lens is now back up and running. Luckily for me an easy fix and I am delighted that TTArtisan were able to send me the parts.

3D-Kraft.com Posted May 11, 2024 Share #26  Posted May 11, 2024 (edited) Today I also tested the lens on an M8.2 (where you get an equivalent to 120mm FF). Focus calibration was not good, but after a manual adjustment (at f/1.25), it fits perfectly fine at 2.5m as well as at "infinity" (also focused on rangefinder). As already noted earlier, the optical "infinity" does not match with the scale and the mechanical "infinity" stop on the focus ring but on a calibrated lens you should be able to trust the rangefinder. I could not see any significant focus shift when stopping down the lens, as you can see from these "out-of-cam" JPEGs: f/1.25 (RF focused on the cap nut at about 2,50m distance): Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! f/1.4:  f/2.0:  f/2.8:  But to be honest: Focusing a 90mm lens at f/1.25 with a rangefinder is quite challenging (but with an EVF it also takes some time)...

ssellars Posted October 21 Share #27  Posted October 21 Advertisement (gone after registration) Hello, just wondering if anyone has added/painted a 6 bit code on their TTArtisan 90mm f1.25? If so what did you use? Thinking the Leica Summilux 90 1.5 might be close but can’t find the code for these yet in searching web images (none show full flange with code?)
