Mornnb Posted March 20, 2015 Share #102 Posted March 20, 2015 I've have some lock ups. I think it may be related to the sandisk cards I'm using. I'll see how it goes with the Lexar. Link to post Share on other sites More sharing options...
Mornnb Posted March 20, 2015 Share #103 Posted March 20, 2015 There is an essential difference between a hand-built camera and a robot-built one.A robot can go wrong, but if one pulls samples off the assembly line and tests them to destruction, any fault found will apply to the others of the run, making correction and quality control consistent and close to 100% A camera built by human beings will be subject to random faults. That means each and every camera must be checked, and can only be checked without taking it apart. That means quality control in a hand-built situation can never be as good as in an automated production process, no matter how hard you try. This does not excuse, of course, weird lapses like upside down rings, cameras fully out of adjustment, etc. That aspect certainly needs tightening up. Otoh, anybody who has a business can recall instances when a process had numerous check points and and each and every one of them failed... Canon and Nikon are mostly hand built. From robot machined components. See this video from Canon for an overview of their manufacturing process. Watch at 2 minute mark, Canon uses robots for lens elements. As Canon finds this the best way to achieve the required optical precision. But the camera bodies are entirely put together by hand as you can see from 9:00. In this one you can see the hand assembly of a Canon lens. Leica is not too different. Robots now make the lens elements, humans put them together just like Canon. The question of quality all comes down to how much is spent on quality control and how much is spent on choice of materials. You'll also find a Canon factory is a mass production and much more rushed environment. Hence the engineering team tries for designs that don't require precision quite as high as Leica. For example look at the frame in the Canon video at 3:10, quality inspecting over a dozen elements at once. These are both amazing companies. There is a special mix of art, engineering and science in any great camera company. Link to post Share on other sites More sharing options...
Exodies Posted March 22, 2015 Share #104 Posted March 22, 2015 There is a big difference in the precision required by a range finder camera and one which focuses through the lens. The latter just needs to find focus. A range finder has two mechanical systems one of which measures distance and the other moves the lens to focus at that distance. This is surely a much harder problem. Link to post Share on other sites More sharing options...
Mornnb Posted March 22, 2015 Share #105 Posted March 22, 2015 There is a big difference in the precision required by a range finder camera and one which focuses through the lens. The latter just needs to find focus. A range finder has two mechanical systems one of which measures distance and the other moves the lens to focus at that distance. This is surely a much harder problem. SLRs have become a lot more like rangefinders since they became digital. You have two electronic systems. One which measures the focus via light that is reflected from the mirror, this is a phase AF system and is in effect a miniature rangefinder on a microchip. And the other is in the lens which is controlling a motor to achieve focus. So that's a system to measure the focus and another system to move the lens to focus at that distance. Modern DSLRs have as many if not more calibration issues than Rangefinders, however this tends to go unnoticed unless people are using very fast lenses like the 85mm 1.2. There can be all sort of issues, like a mirror or phase AF chip out of alignment or a worn out lens motor that has lost accuracy. However there are a couple of issues which make precision a bit more important on a Rangefinder. On a DSLR because it's electronic, you can calibrate it yourself via options in the menus. The other issue is there's a feedback loop, the camera will ask the lens 'Did you achieve the focus position I asked you to? No, well try again' This can still fail however if the position sensor in the lens loses calibration. Link to post Share on other sites More sharing options...

I assume that the language a DSLR uses to talk to itself is selectable, buried in some menu? These cotton picking new fangled DSLRs are just way over my head. I'm sticking to the M.

Carduelis Posted March 26, 2015 Share #107 Posted March 26, 2015 Advertisement (gone after registration) I updated the firmware once about 8 months ago I guess and am currently using version 2.0.0.12. I have now caught up with the firmware and now using version 2.0.1.7. The horizon indicator now works a treat; hopefully my previous issues will be solved. Thank you Leica.

Photoskeptic Posted March 27, 2015 Share #108 Posted March 27, 2015 Brent, I had a lockup with my rental M240 - turn off and back on and everything was good. My M-P has been terrific. As long as it continues to match my M8.2 (never a problem) then I'll certainly remain a happy camper. It's not as simple a camera as the M8.2 but the features over the 8.2 are very, very nice. The increase in mp's is most welcome. Link to post Share on other sites More sharing options...
jto555 Posted March 28, 2015 Share #109 Posted March 28, 2015 I have two M240 bodies. The first one (November 2013) has been back to Leica for a new mother board and it does lockup every now and again. Plus it still has a slight backfocus issue with longer lenses. My second M240 (January 2015) has not yet had a lockup and the focus is 'bang on' with all lenses. Link to post Share on other sites More sharing options...
Mornnb Posted March 29, 2015 Share #110 Posted March 29, 2015 I fixed the Lockup issue I had by changing to a Lexar card. Formatted with SD card formatter. The other issue I had was paint coming off the Info button. But I'm not bothered by that in the least, it looks just fine without paint. Link to post Share on other sites More sharing options...
fotografr Posted March 31, 2015 Author Share #111 Posted March 31, 2015 Thanks to everyone who contributed to this thread. It's now a done deal, I have a new M (240) in hand and am just waiting for spring to bust out here so I can get out and put it to work. Link to post Share on other sites More sharing options...

It's now a done deal, I have a new M (240) in hand and am just waiting for spring to bust out here so I can get out and put it to work. Don't wait. We want to see the last dregs of Wisconsin winter. It's 80 degrees here and sunshine. Quite boring. Link to post Share on other sites More sharing options...

plewislambert Posted April 1, 2015 Share #114 Posted April 1, 2015 Reading through these threads, one gets the impression the M (typ 240) is plagued with problems. Are there people whose copy has been trouble free? I used an M9 for a couple of years before moving to an M240 (noticeably better). Never had a problem other than incompetence Philip Link to post Share on other sites More sharing options...
tookaphotoof Posted April 1, 2015 Share #115 Posted April 1, 2015 Well, after my flight to Hongkong, the part with the shutter speed info in play mode was all over the place. For a day. Luckily all works fine again. Still happy with my digital brick. [emoji4] Link to post Share on other sites More sharing options...
