Mauribix Posted November 5, 2007 Share #1 Posted November 5, 2007 Advertisement (gone after registration) Does anyone knows what kind danger shows up to Sensor when cleaning it using Bulb mode? I wronfly did it, then suddenly read in the last LFI not to do it! Experiences? Damages? cheers Maurizio Link to post Share on other sites More sharing options...

Guest Posted November 5, 2007 Share #2 Posted November 5, 2007 In B mode I think the sensor is live.Always use the sensor cleaning function,thats why its there. BrianP Link to post Share on other sites More sharing options...
stunsworth Posted November 5, 2007 Share #3 Posted November 5, 2007 Well if you let go of the shutter button you'll have one very ill shutter. Link to post Share on other sites More sharing options...
rwfreund Posted November 5, 2007 Share #4 Posted November 5, 2007 When charged, the sensor will have a static charge which will make it more difficult to clean. Dust bunnies are attracted to static I hear. -bob Link to post Share on other sites More sharing options...

Mauribix Posted November 6, 2007 Author Share #7 Posted November 6, 2007 Advertisement (gone after registration) I know well that i didn't have to do it, but the fact was this: I found myself in a windy day, when, changing my lens a little piece o paper was driven by wind right into my camera. I cidn't suddenly realized what happened, but as soon as i did the shot i could see a big big big UFO into the sky of my shot. I realized that obviously something was not working at all, i tried to use the "cleaning sensor" utility mode in the menu, but my lovely M8 told me:<< sorry,you shouldn't have used me and keep the battery charged to make me leave you clean under my sensor>>. So what should I (and you all, guys) have done? Leave the Unkown Flyin Object layin' over my sensor, finding eventually something terrific like oil-on-paper, acid-on-oil, oil-on canvas.... and leave it react eventually on the surface of my sensor (maybe damaging it)?or try the Bulb position (as nikon and canon users hav done for a couple of years) and clean it right there? I think the second choice was the best one, and this fact just to say that is REALLY BOTHERING ME this fact about battery charge/cleaning sensor. The first time i really needed it, it was no way useful. Now i'm here.... criticize me.... are you talking to me? are you talking to me?

gwelland Posted November 6, 2007 Share #8 Posted November 6, 2007 Maurizio, In the real world we have to make decisions like this. I do think that the menu based approach is best but the threshold for battery charge is probably set too tight for it to be useful when you're out in the field. Hindsight might say that you should always have a fresh 2nd battery available but if you're like me, you can guarantee that this would happen when that 2nd battery is IN the camera! I wouldn't worry about the charged sensor. The only thing that would have happened is that your cleaning might not have been as thorough as if the sensor clean mode had been used. The downside is that the sensor will still attract some of the cleaned dust back when you clean it this way. I think you're pretty safe with pieces of paper! If you're worried about the sensor cleaning, charge the battery and do it again using the sensor clean mode. For most cleaning the use of a rocket blower is more than sufficient. You don't need wet/dry cleaning every time. It's easy to obsess over sensor cleaning but if you apply common sense to the job you soon realize that the cover glass isn't going to instantly shatter if you clean it, it isn't going to scratch unless you rub dust/rock particles over it, and it won't turn to goo if you do a brush or blower clean on it. Just be gentle and treat it like it's $5000 worth of camera all on that sensor. Link to post Share on other sites More sharing options...
stunsworth Posted November 6, 2007 Share #9 Posted November 6, 2007 Maurizio, the advice offered was good. If you use the B setting then you risk severe damage to the sensor. Provided you understand that and are still happy to use that method again then go ahead and do so in the future. To say that the advice was 'no way useful' is not the way to get people to help you in the future if you have a question or problem, particularly when the advice _was_ useful in that it told you of the possible issues arrising from using the B setting.

As an emergency measure I understand your choice.And if one stays away from the sensor/shutter path with the Rocket blower it should not be that hazardous. But reasons like this are my argument for the idea that one can never have too many charged batteries - or SD cards in one's bag..... And don't forget, these forums are read by uninitiatated users as well, so a clear don't is needed..... Link to post Share on other sites More sharing options...
Mauribix Posted November 6, 2007 Author Share #11 Posted November 6, 2007 ...To say that the advice was 'no way useful' is not the way to get people to help you in the future if you have a question or problem, particularly when the advice _was_ useful in that it told you of the possible issues arrising from using the B setting. Sorry Stunsworth, i was not referring to the advice that peoplepreciously gave me (that of of course is meant to be the best of each one thought and experience!, and that's why I ask advice to you all), i was referring to the menu setting "sensor cleaning"(that has been useless to me in that particular case), I had my second battery in the camera yet (yes Jaap, it was!), and i think it's quite restrictive to be disabled when 2/3 of the battery is still charged. Maybe a new request/dream for the next firmware? I used a Rocket Blower to clean the sensor that time, and now no visible effects showed up on my camera, i just asked what could I expect then... This was the starting point for a new debate on our camera's improvement! Each one of us, i guess won't clean sensors outside of our kitchen walls So my doubt is: Shouldn't be considered an emergency procedure to remove accidental UFO over the sensor? Or then again: is it a fool question, to know from our mothership Leica, what could happen in situation like this instead of just the reply "don't do that"? anyway, thanks for your attention! best Maurizio Link to post Share on other sites More sharing options...
george + Posted November 6, 2007 Share #12 Posted November 6, 2007 I think we all owe Maurizio a vote of thanks for letting us know what we can do in an emergency. Not recommended? Of course not. Dangerous? Possibly. But in an emergency it may be a way out. Thank you! Link to post Share on other sites More sharing options...
gwelland Posted November 6, 2007 Share #13 Posted November 6, 2007 I agree with Jaap, there are emergency procedures but please use the proper approach as getting a new shutter and possibly messing up the sensor at the same time if you release the shutter will make for a very sad day. I probably shouldn't mention the 'field cleaning' approach demonstrated on the Leica workshop tour ... (The lens off, invert, sensor clean mode, strong blow across the sensor ... hey, I wouldn't do it unless I wanted to risk sticking stuff with tiny saliva drops but .... ) Link to post Share on other sites More sharing options...

(The lens off, invert, sensor clean mode, strong blow across the sensor ... hey, I wouldn't do it unless I wanted to risk sticking stuff with tiny saliva drops but .... ) Leica cleaned the sensor by blowing on it??? I'm very surprised at that, it's a total no no as far as I'm concerned for exactly the reason you mention. I'd have thought the stronger the blowing, the more crud you'd get on the sensor.
