viramati Posted August 9, 2013 Author Share #21 Posted August 9, 2013 Advertisement (gone after registration) Adapters: LTM to M Cet the codeable ones. have you tried them on the M and do they read the codes? the ones I bought from china 1 worked on the M9 and neither on the M240 Link to post Share on other sites More sharing options...
Advertisement Posted August 9, 2013 Posted August 9, 2013 Hi viramati, Take a look here 'No lens connected' M240. I'm sure you'll find what you were looking for!
wlaidlaw Posted August 9, 2013 Share #22 Posted August 9, 2013 The Jinfinance ones are OK for the price but some have reported non-pick up of code. I have found that unlike the M9, where silver is a perfectly acceptable substitute for white, for zero codes the M240 likes white. I have had no problems myself with Jinfinance ones.

jaapv Posted August 9, 2013 Share #23 Posted August 9, 2013 have you tried them on the M and do they read the codes? the ones I bought from china 1 worked on the M9 and neither on the M240 Yes I have a couple and they are fine. Link to post Share on other sites More sharing options...
RotarySMP Posted October 4, 2013 Share #24 Posted October 4, 2013 This thread motivated me to go and measure my LTM adapters thicknesses: I have 2xM mount and 3 LTM lenses, but no LTM camera bodies so I have three adaptors. It's an imperial Mitutoyo 0-1" 0.0001" scale micrometer. #1 - €10 Ebay/ 35 frame line lug =1.007mm (0.3940" - 1.010mm (0.3942"). Nearly parallel, closest to nominal thickness. This is the one that lives on my Jupiter-12. #2 - €10 Ebay 28 Frame line Lug = 1.010mm (0.3942" - 1.027mm (0.3948") Flanges are less parallel. I use this one on the Voigtländer 15. #3 - Unknown source 28 frame line lug = 9.977mm( 0.3928") - 9.990mm (0.3933") ( This one won't latch on the bodies anti rotation (lens release) widget. It is tight enough that it doesnt fall off, it lives on a Canon 28 F2.8 which I don't like. Link to post Share on other sites More sharing options...
Ecar Posted October 4, 2013 Share #25 Posted October 4, 2013 This thread motivated me to go and measure my LTM adapters thicknesses Whilst differences in thickness may create other problems (e.g., focus), I don't think it's related to the issue being raised here. Rather a problem with precise alignment between adapter and sensor and/or "light leaks" and/or surface reflectivity - all of which seem to prevent the sensor from accurately reading the code.

01af Posted October 4, 2013 Share #26 Posted October 4, 2013 #1 - €10 eBay 35 frame line lug =1.007 mm - 1.010 mm. Nearly parallel, closest to nominal thickness. This is the one that lives on my Jupiter-12.#2 - €10 eBay 28 Frame line lug = 1.010 mm - 1.027 mm. Flanges are less parallel. I use this one on the Voigtländer 15 mm. You should swap them. A 15 mm lens is way more sensitive to flange-distance and alignment errors than a 35 mm lens. Link to post Share on other sites More sharing options...
