Fontan Posted July 19, 2020 Share #1 Posted July 19, 2020 Advertisement (gone after registration) Hi guys Soooo, I got this very goofy problem with my M10. When I have my Pentax-l 43/1.9 special (M39 thread) via an adapter on my M10 every time I am in bright light surroundings, LV or EVF just switches off by itself. When indoor for example no such phenomena. It’s very annoying. Previously I had M240 and no such issues. Any thoughts? Could it be the adapter? Gracias in advance. 1 Link to post Share on other sites More sharing options...

m.birnbacher Posted July 19, 2020 Share #2 Posted July 19, 2020 when the bright light hit the lens ensor on the M10 body the EVF switches off. You schuld use a adapter that covers the sensor i used a peace of black paper - that helped:-) but I used it for just a few test shots greetings from Nuremberg Michell Link to post Share on other sites More sharing options...

Hi, I have the same issue when I mount an MS Optics 24mm Aporia to my M10-p (it's a very small lens). The problem is that the lens does not fully cover the mount, so there is light that leaks in in the gap between the lens and the mount where the six-bit code reader is. If it detects light, it'll switch off live view because it assumes that that means no lens is installed on the camera. If I cover the gap fully with my finger, live view won't siwtch off in bright sunlight. 1 Link to post Share on other sites More sharing options...

mujk Posted July 19, 2020 Share #6 Posted July 19, 2020 This happens when you use a 39toM adapter that has a cutout just where the lens code sensor elements are located in the mount, resulting in ambient lighting being able to reach these and causd this error. It's not really a light leak but a design feature of the adapter so that it doesn't obstruct the infinity lock of some older screw mount lenses. 2 Link to post Share on other sites More sharing options...
lucerne Posted July 19, 2020 Share #7 Posted July 19, 2020 (edited) Advertisement (gone after registration) For my M10 and 1951 Leitz 35 f:3.5 (LTM) I've just located a (rare) KIPON LTM to M adaptor (on Eb///) which has a shorter cutout and covers the lens code sensors at all times.. (it also has pits to allow permanent marking/coding of the LTM lens) . This method supports your EXIF record. Alternatively however, you can also stop the sensing by switching it off in the menu. You should buy the KIPON or similar which matches your lens focal lengths. Commonly 35-135. The Infinity Lock is still functional.

TomB_tx Posted July 19, 2020 Share #8 Posted July 19, 2020 Rayqual makes an adapter similar to the kipon, but I think higher quality. 1 Link to post Share on other sites More sharing options...
lucerne Posted July 19, 2020 Share #9 Posted July 19, 2020 (edited) Tom What evidence do you have for such a statement. have you handled both. What quality deficiencies did you observe. Dont be fooled. There may be some poorly made products but the kipon is fully profiled and well finished. Its not the cheapest and it does what its supposed to do. The Rayqual is very overpriced. What do get for the extra cost? Nothing! Its a single pressing. Once its fitted to the lens youll not need to touch it again.

Fontan Posted July 19, 2020 Author Share #10 Posted July 19, 2020 (edited) Well - I tried to cover it up and so on, but it is just hit and miss, so I ordered another one adapter from K&F. https://www.kentfaith.com/KF06.277_m39-50mm-75mm-lenses-to-leica-m-camera-mount-adapter?gclid=Cj0KCQjw3ZX4BRDmARIsAFYh7ZLpDjHdl6olZCvDc7GjbT-GpyX0arD2sP2xY9rwCVlZeJUcKVOsKWUaAu5HEALw_wcB Will see if this works better. If not, I can always send it back, I suppose. I am willing to go an extra mile because Pentax-l 43/1.9 special is, well, very special. I love the sharpness and the rendering. Welcome, dear visitor!

There are other adapters available without the cutout if you dig around. I have a couple old Voigtlander adapters without the cutout.

Once its fitted to the lens youll not need to touch it again. Good point - KIPON is a reputable manufacturer, and the products are generally good quality. The KIPON ltm/M adapter I have does have an appropriate cutout to work with most lenses, and covers the 6-bit sensor with an area with machined pits for encoding. The adapter is satin-chrome plated without grinding off the plating on the rear seating surface as was done on the original Leitz adapters (to assure plating thickness did not affect the registration distance). The satin-chrome has a definite texture, and I notice it has scuff marks on the back after some use of mounting-removing. Leitz used bright chrome with a smooth finish. The genuine Leitz adapters I have all measure flange thickness of 0.98 to 0.99 mm measure at points all around the circumference. The only KIPON I have measures from 1.02 to 1.07 mm measured around the circumference - so about 0.05 mm variation on the same part. I suspect that may be variation in plating thickness causing it. The Rayqual adapters I have also have a similar partial cutout to work with most lenses, and cover the 6-bit sensor with a machined channel (instead of individual pits) in area needed for coding with paint. These also have a satin chrome finish (black on these), but seem to have less texture than the KIPON, and also do not grind it off on the back side of the flange. The two Rayqual adapters I have measure flange thickness of 0.97 to 0.98 mm all around the circumference, so consistency is on the same order as the Leitz adapters. Voigtlander were the most like Leitz that I have seen. I would count both KIPON and Rayqual as good choices compared to other brands of Chinese adapters that I have tried - some don't even have the 3 small cutouts to remove the flange if it gets stuck in the camera body. But as I suggested, I think Rayqual has a slight edge - based on the few samples I have. 1 Link to post Share on other sites More sharing options...

But it can be coded is my understanding. The lens I’m slapping on is Pentax-l 43/1.9 m39 screw mount so coding doesn’t matter . . . . 1 Link to post Share on other sites More sharing options...
