hello all -

 

please find below a very much cropped part of a picture i took earlier today. it's the 'sky' part of the picture (f6,7 - 1/250, brand new elmarit 28mm)

 

are these 'dots' i see all over the place typical to dirty sensors? and if yes - i assume wet cleaning needs doing?

 

many thanks!

Wet cleaning may well not be required. Have you used a 'rocket' blower (with the shutter curtain up) to see what difference is made to images of sky after? I can't see your image; but think dust is most likely, and this rarely requires a wet clean. Try a Zeeion (as it blows and anti-static charge).

Yes, that looks like the crud the M8 and M9 generally seem to exude in their first months. If so, I think wet-cleaning is the only solution.

 

Ditto. I would recommend that you use top quality stuff (eg, invisible dust). Should not be a problem that way.

Those spots look just like the ones I get on my sensor. But you have them at several times the density I've ever had them. Do you change lenses outdoors?

 

We all say they are on the sensor, but if you need proof, try two different lenses.

 

To repair shots taken before the problem is cleaned up, I use the Speck Removal tool in Picture Window Pro. You adjust the radius of a circle, position it, and click several times. Does a great job.

That is one seriously dirty sensor!

It may well need wet cleaning, but start with a blower (camera upside down) and before opening the shutter blow out the camera inside. Then you'll need a loupe and an Arctic Butterfly at the very least. If after that using the 'Fly there is still crud on the sensor, wet clean. It's all not too difficult if you take your time and it's well worth learning how to do it.

There's plenty of threads here about the process if you do a search.

If you really want to see just how dirty your sensor is:

Put your focus on infinity, set your aperture to f/16.

Go out side and take a photo of a clear blue sky, or a uniform gray sky, like we have been having up here in NY state, for the last month.

View in your image browser at max and scroll through the image.

You will be amazed how much crude is on the sensor!

 

And you should really learn to clean your sensor yourself, because you are going to be doing it a lot.

 

It's just part of owning a camera that you will be changing the lens's on over and over.

... seems scary the whole sensor job.

It is the first time. Just read the camera's cleaning instructions and the instructions that come with your cleaning kit. Then go at it.

 

The first try probably won't get it. You'll check again after the first try and probably do it again. Maybe a third time.

 

By then, you'll feel a lot more competent.

 

And the next time you need to clean it, you'll hardly think twice.

 

We all worried before doing it the first time, tried it and moved on. :)

 

 

For a simple how-to, see my post at http://www.l-camera-forum.com/leica-forum/leica-m9-forum/175713-does-leica-ship-m9s-dirty-sensors-2.html#post1676780 and Michael Hußmann's response regarding using a wide angle at http://www.l-camera-forum.com/leica-forum/leica-m9-forum/175713-does-leica-ship-m9s-dirty-sensors-3.html#post1676890.

I have always found that if I forget to turn the camera off while changing lenses, I get much more dust on the sensor afterwards, despite the shutter being closed. That applies to Leica as much as to Canon etc.

Wet cleaning. Use the best stuff. If you are not comfortable take it to a leica service.

 

Ditto a second time on wet clean with the best stuff (e.g., Invisible Dust). Like you, I used to be quite wary of cleaning the sensor. But it's pretty easy. Just take your time and remember "less is more." I am quite careful when changing lenses, so I now find it rare that I need to clean the sensor at all--and, if so, it only necessitates using the blower.

In the US, some of these liquid products aren't allowed to be shipped due to risks if the bottle leaks. That means that they can only be purchased by someone physically in the store. :(

 

That may apply in the EU as well. Oh, and of course that means the local store, knowing you can't mail-order it, sells it for more than the manufacturer's list price.

 

Some strange rule if you ask me, since the manufacturer can ship in bulk to the dealer. :p

 

 

Here's a screen capture in this regard from B&H Photo, a major reseller in the US. Note the last line. :rolleyes:
