pico Posted November 4, 2013 Share #61 Posted November 4, 2013 Advertisement (gone after registration) Pico, It really is a Peltier effect cooled DSLR used for ultra low light/long exposure astro photography. See more details of it here Astrofotografie: EOS 450D and . With that size of cooling fan, I don’t think you would have to worry about the noise of mirror slap Wilson Wow. Very nice. Now why can't Leica make that available for the rest of us? Link to post Share on other sites More sharing options...

pico Posted November 4, 2013 Share #62 Posted November 4, 2013 That photograph of the Canon got me thinking about a solution to our lock up issues. I guess when going to hot climates I will start carrying a dry ice cooler where I can put one body inside (adequately protected from freezer burn) while using the other and then when lockup occurs with the one camera I can switch to the cooler one and keep alternating back and forth until the shoot is complete. [...] Funny. I do keep a 110V AC peltier appliance in the truck. It protects from freezing in the Winter and from overheating in the Summer - do a degree, 40F and 80F to be specific. Supplemented with frozen bags in the Summer it works well. Not so great in the Winter. It used to be for film, but lately holds beer. Link to post Share on other sites More sharing options...

Or until I tire of the situation and rid myself of my M240's unless the next FW completely tackles the problem. Ummm...Is it not simpler to switch the camera off directly after shooting and on when you start again? Just a thought.... In my experience, even when the temperature went over 40 that solved the problem. The camera recovers within minutes when switched off. Using two cameras is even more efficient.

jdlaing Posted November 4, 2013 Share #64 Posted November 4, 2013 Wow. Very nice. Now why can't Leica make that available for the rest of us? They could but you'd have to wait over a year to get it. Link to post Share on other sites More sharing options...
thighslapper Posted November 4, 2013 Share #65 Posted November 4, 2013 I'm afraid reading again through this thread just shows what Leica is up against..... .... temperature sensitive cut-outs that usually, but not always happen with high ambient temperatures and EVF use. ..... again, some people have never had any trouble, whatever they are doing, and others have had problems with no real observable pattern. All you can really conclude is that the lock-ups effect some, but not all cameras, and that high ambient temperatures make it more likely to happen. If the sensor circuitry has a 40 deg trip and using all the gizmos and current hungry modes generates more than this then Leica have an insoluble problem......

jaapv Posted November 4, 2013 Author Share #66 Posted November 4, 2013 Oh- it has a pattern and is repeatable. I could predict at what points the cut-outs would start happening - around noon, when the temperatures went past 35 and in the direction of 40, when I was not using the switch-off, switch on method. Additionally the camera needs to be heated up through and through. If you just walk out into the heat from a cooler room it may take a couple of hours before you notice and even then you must have been using it regularly. I really doubt that it is the sensor cutting out. The camera takes the shot, writes it and then it freezes. If you have a review going it will remain displayed in the EVF to LCD. Switch off and on it will be ready to take a single shot again. That suggests to me that somehow the problem is in last phase of the software cycle, some final reset not functioning..

woorob Posted November 5, 2013 Share #67 Posted November 5, 2013 Advertisement (gone after registration) FWIW, I encountered this issue (so far, once only) within the first 50 exposures with my new M, at an ambient temperature of less than 50f (using the EVF).

algrove Posted November 5, 2013 Share #68 Posted November 5, 2013 Also some are not mentioning that there exists two types of lockups. The first it freezes and a simple on/off gets it going again. Then there is the more serious type of lockup where the red light stays lit with no blinking. One must remove the battery to clear this type of lockup and one looses the last image, never to be seen again. A royal pain in the ass, this one.

vikasmg Posted November 5, 2013 Share #69 Posted November 5, 2013 If the ambient temperature is over 37 degrees Centigrade letting it run in LV/EVF will push the internal temperature too far beyond the specified maximum of 40 degrees. I happened to visit Dubai late last month and when I walked out of the terminal the temperature was about 35 decreed C well after sundown. I asked the driver who picked me up if it was typically that kind of temperature. He replied "No sir, it's almost the start of winter soon." My M worked just fine though. Interestingly it never got much above 37/38 wile I was there. Link to post Share on other sites More sharing options...
jaapv Posted November 5, 2013 Author Share #70 Posted November 5, 2013 I have never experienced that one. I don’t think it is temperature-related Also some are not mentioning that there exists two types of lockups. The first it freezes and a simple on/off gets it going again.

Obbucket Posted November 5, 2013 Share #72 Posted November 5, 2013 What were you doing at the time and what happened? I had this happen in two scenarios 1) while using the EVF and it occurs very now and then. 2 ) a couple of times when I have taken a photo and viewed on screen but have not switched the screen off and have found the shutter to be locked. In both cases battery removal was required Link to post Share on other sites More sharing options...

Had the second more annoying one this last weekend on a trip to France. I would say it was about 18 deg C. Lost the shot too. But hey, all part of the Leica Experience right? Edit - solid red light light accompanying the lock up. Battery out, pause, back in fixed it. Link to post Share on other sites More sharing options...

But hey, all part of the Leica Experience right? Sorry. Those are the most annoying because you loose the image. 18 deg C is not hot so now what gives?

Past expecting a solution from Leica (hey, I'm a previous M9 owner, I've lost many shots to lock ups with Leica) Just suck it, the other issues and the price tag up until a viable alternative shows up I guess.

That is why I have decided to try an a7r and if any wides work with it I will reduce M bodies down one or less over time. I can rotate 3 a7r for the price of one M.

Paul J Posted November 5, 2013 Share #80 Posted November 5, 2013 Just a thought: Something like these Adhesive Instant Cold Packs One of those on the top plate and over the back may take the edge off it if you really need it. Link to post Share on other sites More sharing options...
