jaapv Posted July 15, 2014 Share #61 Posted July 15, 2014 Advertisement (gone after registration) I stand corrected about the presence of a sensor cleaning system, but from the same publication: which includes a self-cleaning sensor unit with four different resonance frequencies to vibrate the optical low-pass filter However, the D800 has a substantial filter array which has quite a bit of stability. (again from this publication and the IR filter is probably double the thickness of the M. The Leica M cameras have a very thin IR filter as evidenced by the M9 sensor crack problem. The M240 filter may be a bit stronger material to prevent cracking, but is just as thin, as shows from the IR sensitivity. I shudder to think that those filter glasses would be subjected to vibration. Link to post Share on other sites More sharing options...

Or maybe it is possible, and Leica just didn't want to include it, for whatever reason. We have seen so many items/details that Leica didn't have, which where defended/declared here as impossible or undesirable ... until Leica included it in the next camera generation.

jaapv Posted July 15, 2014 Share #63 Posted July 15, 2014 Or undesirable. This shaking technology is just a stopgap until dust-repelling nanocoatings become available. Link to post Share on other sites More sharing options...
jaques Posted July 16, 2014 Share #64 Posted July 16, 2014 pretty good stop-gap: my 2008 Canon DSLR rebel only has one small spot visible on images after 6 years of use and more than 12,000 frames. I change the lens often and never cleaned the sensor... Link to post Share on other sites More sharing options...
jdsheepdog Posted July 16, 2014 Share #65 Posted July 16, 2014 We have to remember there is a an increasing number of people, probably a generation now, who are unable to do things. As kids they have never fixed a puncture on their bicycle, they have never gone fishing, they have never made their own toys to play with. So they grow up incapable of the simplest coordinated tasks. How true, how sad, but how true. Link to post Share on other sites More sharing options...
jdlaing Posted July 16, 2014 Share #66 Posted July 16, 2014 We have to remember there is a an increasing number of people, probably a generation now, who are unable to do things. As kids they have never fixed a puncture on their bicycle, they have never gone fishing, they have never made their own toys to play with. So they grow up incapable of the simplest coordinated tasks. Leica are going to have to do something about it if for no other reason than they can't have expected the 'free sensor cleaning' to be continually used time and time again in all their world stores, I'm sure they anticipated owners getting down to it themselves at some point (hence the menu command). And 'free' is a warped way to look at the service, firstly spending time going to and fro to the shop, but it also doesn't allow freedom to have the sensor cleaned at the critical time of when dust is first noticed, be it on holiday or on assignment. Managing expectations is a tricky area, at the moment there are a majority of owners who accept dust is a way of life and deal with it as they have with other camera's in the past, but some owners are new to digital, new to photography in some cases, and it is a shock to them. And it won't get better as owners migrate from smaller P&S cameras that already have self cleaning sensors. So roll on Leica's first self cleaning sensor, it will probably make the camera even bigger, but that is the price to pay for the sake of five minutes use of the appropriate tools in the comfort of the owners own home. But in the longer term it has to happen. Steve Perhaps the previous generation never took time to teach them. Another case of poor parenting and mentoring. Too busy filling their pockets with money and ignoring reality. Link to post Share on other sites More sharing options...
justj Posted July 17, 2014 Share #67 Posted July 17, 2014 Advertisement (gone after registration) It just like buying a pair of underwear and find there is a lot of "stains" on it. But no worries, you can always wash the stains off and enjoy your new underwear just as much. Link to post Share on other sites More sharing options...
