Does your Leica sensor have defects?

My sensor has spots from time to time. When they start bothering me I clean it and it will have none for some time.

 

I wonder why you ask as it is well known that foreign substances will remain on sensors. Otherwise, there would be no explanation for the fact that products exist for that very purpose.

All my 5 Leica sensors have spots from brand new.

 

So let me clarify the thread...

 

 

Did you get a perfect sensor when buying your new Leica or does your Leica sensor have spots on the photos?

It actually doesn't matter. Since in normal use you'll very quickly get crud on your sensor and have to clean it, just learn to clean the sensor properly and do it. My M 240 quickly got lots of either oil from the shutter or pollen on the sensor, not sure which.

 

Cleaning the sensor takes a couple of minutes. It will take far longer to buy the right implements for the job. Might as well buy those along with the camera. You're definitely going to need them.

I have no idea at all if at the very moment I unpacked it the sensor was perfectly clean. You can't check the cleanliness without putting a lens on, and you can't put a lens on without possibly putting some dust in the camera.

As Steve says the first time you mount a lens , from the first time you take a shot and open the shutter you can get dust on the sensor. Keep a good blower, preferably one with a filter, and blow out the dust caps, rear lens elements and the camera chamber whenever you can. In the end dust on your sensor is inevitable and whether it is there from the first few shots or not is really irrelevant as at some point you will have to deal with it. Maybe a future M will have some sort of self-cleaning feature

Dant are you checking them for dust spots straight out of the box or are you seeing dust spots on photos you took ?

 

Can't say I ever saw a dust spot on a new sensor but then again I don't go looking for them. If it doesn't show on the final image I don't care about them.

 

If a blower works in removing that one annoying spec then its good enough for me.

My experience is the sensors tend to get a couple of dirt spots in the first 3 months of use that are easy to clean . Very little dirt problems after initial clean. I always try and change lens with protection from wind and with camera facing down, with the rear element etc dust free.

Within the first month or so, I noticed I had some dust on the sensor and used a blower to clean it. I don't know if the dust was there from the factory or whether it got there during a lens change. I guess it doesn't matter how it got there, it took a few seconds to clean. Plus, I'm certain I'll get dust in the camera again.

Don't know if they are dust spots. They show up in the sky. More like little round blurred defects. Blowing does not remove. I spot them out. Better than spotting film, but still prefer no spots.

A few spots on all the Leica digitals I have owned. Shooting wide open solves that problem. :)

Yes, that is what I noticed. But why would aperture matter? Wouldn't open aperture be more of a cure for dirt in the lens?

Dirts are not defects, they're just dirts. Suffice it to clean your sensor to remove them more or less. It is difficult to remove them all but you will see them at small apertures mainly. At wide apertures they will remain invisible for the most part.
