dust/dirt? in Digilux2

[Herman.]

Advertisement (gone after registration)

I am using the Digilux 2 since several years and am extremely pleased with it. I'm surfing this forum on a very regular basis and I'm convinced someone can help me with the following question: I am now on holiday and discover a weird "thing" on the pictures. It only shows in the picture itself, especially when aparture 11. It is probably dust or a hair. Is their a possibility to get rid of it myself or do I have to send it into repair? Thanks in advance for any tip. PS: the sensor has been replaced, maybe dust got in it then?

Herman--

I think the lens/sensor unit is a sealed cell and I don't think you can do the repairs yourself. I believe that the units are assembled in (supposedly) clean rooms.

 

Your assumption is reasonable that the foreign matter may have intruded during sensor replacement; but it may also have been there from the beginning, and only got dislodged during the sensor replacement.

 

Either way, it sounds as if the camera needs to go back to the same agency that did the sensor replacement.

Thanks for the quick reply HC. I was hoping ...

At f11, particularly at the shorter focal lengths in certain light conditions dust on the lens can show up. Might be worth having a look before doing anything drastic.

 

As others have said the sensor is in a sealed unit. Even if it has been replaced I am sure Leica wouls have carried out the work in appropriate conditions.

Herman, my doughter Pilar has replaced the sensor of her Digilux 2 and a big shadow has appeared in the screen and in the image. Same problem than yours. I think Leica has not had the care necessary when replaced the sensor.

 

What are you trying to do?

To be on the safe side I will bring it in as soon as I get home. To show what I'm talking about: on the attached picture I took yesterday you can see the problem at the top right. I checked the lens thoroughly and can't find anything.

Hi, it does not seem to work with the attached files, sorry for that. I will try later on when I can log on again. Thanks!

I don't know which forum editor you're using, but if you are using the default simple one, here's how to post images:

 

Compose your message as you've been doing.

 

Scroll down to "Attach Files" and click the "Manage Attachments" button.

 

That brings up a window (see image below) offering several "Choose File" buttons. Click one and navigate to and select a file on your computer. Repeat with another "Choose File" button till you've selected all the files you want to upload.

 

Then click "Upload" and wait till that window shows that all the files have been uploaded.

 

At that point, you can click the "Close this window" button.

 

Now when you click "Submit reply" in the Message panel, the files will be posted as well as your text.

 

Do note the restrictions on file types and sizes in the "Attachment Key" section of the "Manage Attachments" pane and if necessary, adjust the files before upload.

 

I hope this helps. I'm quite curious to see what kind of problem you're having.

Thanks for the info HC, we could finally log on again, so here is another try.

Hey Herman,

 

A few months ago I had the usual sensor problem in my LC1. After (free) repairment, I noticed several large dust spots in the sensor, so I sent the camera back to Panasonic and they cleaned it. Obviously, you will never match what can be done in a controlled room during manufacturing, so I think the decision on asking for a clean-up depends on how much dust you have. In your example, I can see a lot of it, so I would definitively give it a try. I think it will look much better after it In my case, after the clean up I can only see one very small and light spot at F11, so I am quite satisfied with the results.

 

Regards,

Julio.

Quite a striking shot, Herman! Pity for the crud.

 

As Brian said above, first thing to check is the front surface of the lens, but this does look as if it's likely to be internal.

 

Looks to me as if it's going to have to go back to Leica, preferably with a copy of an image such as this.

 

Kinda scary to think that these sensors were built with a problem that will cause them to fail, and that this is the best we can expect in repair! But then, that sensor is only 8.8 x 6.6 mm, so grunge we wouldn't normally notice will appear gigantic on the sensor.

I have a different problem with my repaired D2 that might be related. Since the repair I have an smeared area just off of center that shows up in finely detailed shots like foliage when viewed at 1:1. I've gone back through pre-sensor failure pictures and it wasn't there. Unfortunately I have to wait another two months before I can send it back to NJ.

Sorry Hermann, now I have seen the problem like others I think it's another trip to Leica.
