CheshireCat Posted January 6, 2014 Share #41 Posted January 6, 2014 Advertisement (gone after registration) Oh yes, they do, maybe a bit slower because of the insulating plastic. I'm not sure Silicon Valley is the right place to build up experience about low-temperature behaviour of cameras btw. No they don't crash. Of course they will shut down when the battery is gone (which may happen quickly below 0C). And I travel a lot, so I have experienced shooting at freezing temperatures for hours with good and crappy cameras. My 5D2 worked perfectly for 5 hours at -15C, although battery life was noticeably shorter. The 0 degrees lower limits has more to do with condensation than anything else.

jaapv Posted January 6, 2014 Share #42 Posted January 6, 2014 That would be silly. Condensation can take place at any temperature. Link to post Share on other sites More sharing options...

CheshireCat Posted January 7, 2014 Share #45 Posted January 7, 2014 To link condensation to 0 degrees. The lower the external temperature, the higher the chance of condensation. The equation is complex as it takes into account air humidity and heat generated by internal components. Then again, I suppose that the operating range is computed as the intersection of operating ranges of all components used in the camera. E.g. if just one resistor is certified for an operating range of 0 to 40 (for whatever reason), then the entire camera cannot be certified for a wider operating range. I hope you will agree that telling people that their firmware is crashing because one resistor is not certified for -5C is ridiculous, as the lowest the temperature, the better for microprocessors.

jaapv Posted January 7, 2014 Share #46 Posted January 7, 2014 I am just saying that if a piece of equipment fails when operated outside its specified parameters, there is no cause for complaint. Link to post Share on other sites More sharing options...

I hope you will agree that telling people that their firmware is crashing because one resistor is not certified for -5C is ridiculous, as the lowest the temperature, the better for microprocessors. True for the microprocessor and sensor but for reasons I can't provide explanation electronic devices tend to work best in moderate temperatures ranges, maybe something to do with voltage regulation. If only batteries performed as well as microprocessors at lower temperatures, now that would be very nice. Link to post Share on other sites More sharing options...

barjohn Posted January 8, 2014 Share #51 Posted January 8, 2014 The lower temp limits for cameras has more to do with the fact that the LCDs don't work well in low temperatures. The memory, microprocessors and sensors work very well at low temperatures. That is why people that want to over clock there processors put cooling like freon cooling systems on the micro processors and for low noise sensors they are also actively cooled. On LCDs the crystal structures can't change states fast enough and they tend to freeze in a state both figuratively and literally. As for Silicon valley or any place that doesn't have cold temperatures being adequate or inadequate to develop electronics to operate in extreme temps, understand that most major manufacturers have temp and humidity chambers to test in. We test for temperature, humidity, altitude, and 3-6 axis vibration. Some of our stuff has to go into space and survive and work so it is radiation hardened too.

Thanks for low temperature EVF/LCD explanation. This gives me confidence that any digital M camera used as intended with optical VF will work in any temperature in which human & camera battery can endure & operate. Use of R lenses on M camera with liveview or EVF will be limited to moderate climates, which is 99% of shooting situations for me and probably great majority of other users.

dugby Posted January 9, 2014 Share #53 Posted January 9, 2014 Had my 1st lockup. Perth 24C with 59% humidity at 1700hrs (good daylight, standing in tree shade) Camera (FW 2.0.0.11) with 6-bit coded 50mm LUX FLE set to 1) Single shot, ISO 200 2) OVF (no evf involved) 3) 64GB Toshiba SDXC 4) 10 shots taken in previous 15mins All I remember was that I had just deleted about 5 shots, and then i got the RLOD (red light of death). Thankfully the ol' sparkies reboot, brought it back to life. Link to post Share on other sites More sharing options...

Now that I think of it, I had deleted a couple of shots just before my last RLOD. Don't remember about the previous ones. Link to post Share on other sites More sharing options...
ray3210 Posted February 12, 2014 Share #55 Posted February 12, 2014 Just had my first lock-up today: I was testing my new C-Sonnar 50mm's focus shift problem, so I used the Olympus VF-2 today all the time. I took around 50 shots in 2 hours, shut off the EVF every time when I am walking around. The temperature today is about 8 degree C, sunny day in Stuttgart, Germany. 1. Auto-Off: 2 Min 2. Lexar 32GB 600x (formatted with M240) 3. Battery around 30% I took one shot and then walked around for a few seconds, was about to take my second shot, the camera was not working at all, no LED blinking, EVF not working, the frame lines inside the VF lit as usual, but still lit up even when I turned the camera off. So I had to pull the battery, and it works again properly when I re-insert the battery. Link to post Share on other sites More sharing options...

TerryB Posted February 13, 2014 Share #57 Posted February 13, 2014 I have just had my first lock ups, Three weeks in Cuba, 20C to 28C. 2200 compressed DNGs taken in total 2.0.0.11 Battery approx. 60% Sandisk 64gb pro extreme 2 lock ups on different days on both occasions I was taking 2 or 3 rapid shots on single setting. Both occasions red led stuck on and camera would not switch off, battery removal fixed things. No images were lost other than anything I would have taken whilst taking battery out. Still love using the camera. Link to post Share on other sites More sharing options...
algrove Posted February 13, 2014 Share #58 Posted February 13, 2014 Ray 3210 When using my EVF I try to not let battery capacity drop below 50%. Even this has not always helped. Link to post Share on other sites More sharing options...
satijntje Posted February 17, 2014 Share #59 Posted February 17, 2014 One lock-up so far. Newest FW. NO EVF!!!! At room temperatures. Just wanted to show my baby to a colleague who owns a M9, and when he had it in his hands it locked up, NO JOKE! So my colleague will stay with this ;9 I assume John Link to post Share on other sites More sharing options...
