Corrosion on M240 sensor ??

Now that we have all vented our frustrations over the M9 sensor de-lamination, how do we know if the M240 has the same problem. This is not a CCD vs CMOS issue, but one of the uv/ir on top of the sensor cover. I would rather have to use the filters than have the current problem.

Leica confirmed the the M240 is not affected

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

I don't trust Leica but I trust my own eyes. After a year of use, my M240 has absolutely no corrosion. I would rather worry about the dreaded stuck pixel column though

Different sensor - different cover glass. Simply no. Lightning never strikes twice in the same place.

OMG - the sensor has corrosion ????!!!!!

Different manufacturer too.

Don't panic, don't panic, don't panic, Paaaaaniiiiiiic!!!!!!!

Actually it can. Well, at least close enough not to make a difference. If I'm going to put my faith in a platitude here it has to be "third time's a charm"

Nobody knows what cover glass is used

And I worry about the red line, stuck/dead pixel, also.

 

That be the second thing keeping me from another purchase.

I guess we should be trying to determine what cover glass is used every single time we buy any camera?

Worrying about these problems will take the fun out of the hobby. Although/ it is Hard not to worry about ending up with a 7000 paperweight. Leica needs to establish confidence in their product with their customers at these prices

In fact, I never realized the importance of the cover glass until recently. M8 IR issues, M9 delamination, Sony A7 reflections, smearing, and astigmatism. I think it's important to know what kind of cover and what thickness in any new camera purchase.

Edward,

 

I totally agree. I never realized the importance of sensor covers and mounts. We have collectively figured this out ourselves without the help of reviewers and inter-web experts. This has all been an exercise in realizing I don't really don't know anything or more precisely, everything.

 

So, what do we get when we read reviews... vegetables! There really is a need for an objective scientific review of cameras this expensive before, we blindly shell out nearly ten grand on cameras that "blow away everything else."

 

Nothing even exists like a group of PhD'd reviewers or even a group of folks educated in the area of optics, EE, material science, etc., looking at cameras in a way that would give us more than platitudes, biased inside industry reviewers and vegetables.

sadly just not true:

By the way, tongue in cheek.

[Exodies]

Would you say there was more information generally available about the physics/chemistry of films compared to the physics/algorithms of sensors?

Is the film information of more use to a photographer than the sensor information?

Well no matter what level of information, at least it is much easier to change film (even in my IIIg) than changing a sensor

 

BTW, just to avoid potential heart attacks, shouldn't there be at least a "?" after the thread title?

Good suggestion and done

Hallo,

Look here: Leica M

[billo101]

The effect does not affect the CMOS sensor of the Leica M (Typ 240).
