atournas Posted March 31, 2012 Share #1 Â Posted March 31, 2012 Advertisement (gone after registration) OK, I did my best, but some dust bits apparently got onto the sensor when I changed lenses on the M9. So, I wonder, would it be useful if there was a transparent changing bag, dust-tight instead of light-tight, for cleanly changing lenses? In theory, a conventional changing bag would do as well, but only after some practice and it might work as a "hit or miss" accessory. Â Paul Link to post Share on other sites More sharing options...

stunsworth Posted March 31, 2012 Share #2 Â Posted March 31, 2012 Don't worry about, clean the sensor when the dust is obvious. Dust is inevitable with a camera that has removable lenses, the trick is to learn to cope with it. Â Even if you used a bag, how would you ensure that the bag itself was dust free?

Guest WPalank Posted March 31, 2012 Share #4 Â Posted March 31, 2012 Dust or oil just happens. There is always the chance that it is some sort of lubricant (oil based that you are seeing). A lot of people (and I believe Leica) dismiss the idea of there being anything internally that could be oil based. Although I have seen it but not the source. Â I always diagnose the spot first. I use surgical loops with fiber optic light and even sometimes a surgical operating microscope (I guess you can use the high magnification device that one of the vendors sells). Then I reflect light in from the side. If oil, in my experience, it reflects a rainbow color much like the sheen you get on roadways after a rainy day. Â Finally I use a wet cleaning product based on what I find. Much like cleaning clothes with specific detergents (or solvents) selected on what sort of substance I am trying to get out of the clothes. Link to post Share on other sites More sharing options...
tobey bilek Posted April 1, 2012 Share #5  Posted April 1, 2012 open the bag to put camera in,and dust goes in also. It is in the air and on the camera already.  The best things you can do  Change lenses with your back to the wind Keep the camera lensless as short a time as possible Keep rear caps on lens and keep the cap inside dust free Keep camera mount down,drop off old lens, have the new already oriented and blown off with your rocket blower, put it up to the camera  Blow out the inside after every outing to get anything that may have found its way inside. This is a precaution to remove dust before it migrates to inside the shutter/ sensor.  I have cameras for years that have had no dust incursion. Just use some caution.  Every few years I clean the sensors as a matter of principle. Link to post Share on other sites More sharing options...
Bill W Posted April 1, 2012 Share #6 Â Posted April 1, 2012 When I change a lens whether indoors or out, I have the lens I am going to put on ready and take other off and there is so little time uncovered I rarely get dust inside. It is a two handed thing, I take the lens off the camera with one hand by pushing in the button and rotating with one motion. Just take a little practice.

250swb Posted April 1, 2012 Share #7 Â Posted April 1, 2012 Advertisement (gone after registration) Wouldn't you rather just clean the sensor every now and again and just get on with your photography in the meantime? It is easy to clean your sensor, you are meant to clean your sensor, and you are meant to change lenses as often as you want to. Â Steve Link to post Share on other sites More sharing options...

pelagia Posted April 1, 2012 Share #10 Â Posted April 1, 2012 Thanks, Simon, for the link to the Pop-up tent. It probably makes sense in certain conditions. I photograph often in the extremely dusty environments, such as agriculture (hay), or shipbuilding (sawdust), where above recommendations do not apply. Â But I laughed loudly at "camera not included" in the Pop-up tent ad. Link to post Share on other sites More sharing options...
Double Negative Posted April 2, 2012 Share #11 Â Posted April 2, 2012 When changing your lenses - as mentioned, keep your back to the wind, etc. but also - keep the camera pointed down. Less chance for crap to be blown (or fall) into the camera that way. Â You cannot avoid dust. Simple as that. Link to post Share on other sites More sharing options...

You can find out if the lights go out shortly after shutting the door. The D2 also has an electrical release which I'm sure you can operate from outside the fridge.  Hence, you can make sure that the lights burn at most when there's no camera in the fridge.

pop Posted April 10, 2012 Share #19  Posted April 10, 2012 I have 21, 28, 35, 50, and 90 mm lenses. Which lens should I use for this, Philipp? Pete.  In order to do this properly, I feel one should use a mint instance of the WATE. Otherwise, do avoid lenses which tend to do cushions; for this application, barrels are to be preferred. OTOH, given the pigmy fridges people tend to install, this could be a very fine case for the Tele-Elmar on the Visoflex III, preferable with the Bellows II. For the white balance to work properly, set the camera to manual. Make sure to adjust it with the fridge wide open and the kitchen in complete darkness or mixed lightning might result which can be frightfully difficult to handle in PP. On the other hand, the temperatures to be expected within the fridge might reduce any thermal noise issues to some extent. Unless you have a fridge you can walk into, no neck strap seems to be called for. Link to post Share on other sites More sharing options...
