RoadsidePicnic — Thu, 05 Mar 2020 22:59:34 +0000

After some years of abuse my Lx100 got a hanful of internal dust spots.

Have any of you ever solved that problem withou taking the camera completely apart? Theres any way to do it with a vacuum cleaner and minimal intrusion?

Used Sigma 18-35 lens purchase Help needed

club_irate — Fri, 29 May 2015 04:20:47 +0000

Hi, there is this person selling his Sigma 18-35 ART 1.8 lens which is 1 year old which i am planning to purchase. I asked him to shine the lens through with a flashlight and it has this dust inside the lens which you can see in the pic. Can anyone here who has a good understanding of this check it out and suggest if the level of dust seen in the pic is fine for me to go ahead and wont hamper the image quality.

Not sharing the exterior pics of the lens as that looked good.

Thanks in advance.

Strange marks on video - Damaged Sensor?

DaleCampbell — Tue, 23 Apr 2013 11:03:34 +0000

So a mark/blotch has appeared on my videos recently! I think it happened after a lens change and there was some dust/dirt on the sensor as well which was visible with a loupe. However the mark in question doesn't seem to be visible when looking at the sensor?! It is present when using different lenses/no lens even It moves in ex-tele mode (to a position which would seem to correlate with the sensor crop of that mode) If I shoot a scene which has an over exposed section it will disappear as I move the camera to place the mark onto the over exposed area- i.e. no present when over exposed

I have tried a blower to remove the dust and also swabbed the sensor with a cleaning kit which removed all the dust etc. but this mark remains!!!

So what does it look like to you and has anyone encountered something similar?

Thanks in advance all!

Strange dots, diagnosing help needed

Ruub — Mon, 10 Sep 2012 09:38:43 +0000

Hello guys,

I have a problem with my GH2.

Made several photos, Tried different lenses, different subjects and even different SD cards (just to cancel out all the variables). In every photo though, these strange purple dots pop up in the right corner of the image. My conclusion: the problem must be with the sensor. Visually checked the sensor, could not see anything on the surface. Tried sensor cleaning out of the menu: did not help. After that I tried very carefully with a dust blower to blow any possible dust particles of the sensor: did not help either. Forgot to mention that I also cancelled out the possibility of dead pixels. On a photo with the lens cap on, nothing is seen...

So I guess, (sticky) dust? Or can anyone with more experience in this field give me an idea of what is causing this problem.

Thanks a lot in forward,

Ruben

Sensor cleaning, Eclipse, dust membrane? (GF1)

alphaomega — Tue, 29 May 2012 05:55:09 +0000

Hello Vitaly and all the community, I am here to kindly ask you for some advice.

My near three years old GF1 collected some dust on the sensor that I'm not able to blow out with my Giotto blower. I have searched the web for viable solutions (other than sending the camera for service) and learned something about the so called "Wet method" sensor cleaning technique based on Eclipse, swabs and PEC-PADs.

But during my research I have read somewhere that in the Panasonic bodies there is a dust protective membrane (part of the anti dust system) placed over the low pass filter of the sensor, preventing the direct access to the low pass filter surface and I don't know if this is true or not.

I guess that you, by dismantling some panasonic body, looked at the sensor many times and coud give me some advice regarding this issue: do you ever noticed that the exposed sensor is covered by a sort of dust membrane or something else? Because if there is such a membrane I think that it is not possible to directly clean the sensor without damaging the membrane and/or the sensor. And more in general, do you have some experience regarding this issue?

Any comment/suggestion is welcome and will be highly appreciated. Many thanks in advance for the attention.

Ciao :)

GH1 dust protection

elc — Wed, 07 Mar 2012 12:20:51 +0000

Hi All — I'm off to shoot a short film in Togo in a couple of months with my GH1, and am concerned about protecting the camera and lenses from dust and humidity. So far I'm planning on storing all of my sensitive gear in waterproof bags with fistfulls of silica gel packets for the humidity, but from what I've heard the conditions are generally very dusty, which can take a serious toll. While out shooting, some people have suggested covering the camera in plastic wrap, and I was thinking about slicing up clear plastic bags to make a hood that would leave better access, but I'm concerned that either method might cause the camera to overheat (looking at ~30°C daytime temps).

Any techniques that have worked for you in the past? General tips?

Many thanks!
