Who Uses The Lenspen For Sensor Cleaning

If you watched the video in post #4 above, you will see the spots I am talking about. I will follow up when the sensor clean pen gets here, The sensor pen also has a three corner shape to get into the corners. It's made for the sensor.

Since Lens Pen has special sensor cleaning devices, that might be why no one has attempted to clean a sensor with something stated to be for lenses and filters. Be sure to report back the results of you attempt to clean the sensor, good or bad.

It sounds like you need to do a bit more research on the various LensPen products. I don't see where anyone is talking about the LensPen itself for cleaning of the sensor.

Let me help you with that:

canonloader,

When you get the SensorKlear, give the cap a couple of twists then tamp the head on a microfiber cloth to shake out excess graphite particles, otherwise they may get on your sensor. I agree with one of the previous posts that once these particles are in your chamber, they may be difficult to totally remove.

I looked at your video and don't see how the pen will work any better than the wet-clean, but let's hope that it will. If lubricant is gumming up the works on the sensor's surface, Eclipse should have taken care of it, so I'm really not sure what's going on. If there's no significant improvement after the pen, you should probably just send it in to Canon.

Yeah, in all the years I've had digital sensor cameras, I have not seen anything quite like this. Not only can I not pinpoint when it appeared, or where it came from, after all these cleanings, it still won't come off.

The fist time I ran in to lubrication on the sensor was with the new 7D. I have heard the new 5D MkII's also had the problem. So this is kind of what it looks like, from my experience. I had to clean my 7D 5 times in a row to get it all. I have used Copperhill 4 times on this. Maybe today, I will give it a couple more wet swipes and see if it gets it. It says a week to go yet for delivery and I am getting impatient. LOL

Again, don't be too aggressive going forward, you don't want to create bigger problems than the present one. There is an extremely remote chance that those particles are under the cut-filter, it's rare but it can happen. If this is the case, all the swabbing and brooming you can do won't touch the stuff. Just be careful, that's all.

That did occur to me. The last cleaning was a dry wipe with a Pecpad after a wet clean and it did seem to get some of it. Not get it, made the spots seem less opaque. I am wet cleaning it again now. I'm going to do 4 in a row and see what happens.

OK, success. I did 4 wet Copperhill cleanings in a row and got all the spots.

But, there seems to be another problem. After owning and using the camera for a year, and who knows how long it sat on the shelf in a box, it has decided to throw off lubrication from the mirror hinges, or where ever it comes from, cause it went from squeaky clean at image 1, to a new spot on the sensor by image 3, but no more since then. Ho hum. I will keep a close eye on it for the next few days though, and I am still looking forward to the lens pens for the microscope lenses. You think a regular photographer has a lot of lenses to keep clean, my microscope has two eyepieces, 6 objective lenses on a turret, two more reducer lenses in the head, and who knows how many prism surfaces in the trinocular head? And then there is another lens in the trinocular head. And this microscope is not sealed like a Canon camera. LOL

I did the research about multiple products even before you posted! LensPen (the company) states about their LensPen (the pruduct) product -- and there are seven lens and filter cleaning products from the company -- ...

"A superb new tool in optical lens cleaning technology.

"Perfect for cleaning camera lenses, binocular lenses, small aperture spotting scopes and telescopes, eyepieces, and other optical items. Comes with a handy retractable dust removal brush and a special non-liquid cleaning element, designed to never dry out. Safe and very easy to use."
There is no mention of digital camera sensors.

The OP statement was "I bought a couple of sizes of Lenspens" (the product) not that "I bought the SensorKlear from the Lenspen company" to clean the sensor. So it was important to point out that the Lenspen (the product) was NOT suitable to cleaning a sensor!

Wilt, I did say "I bought a couple of sizes of Lenspens and one for the sensor". I had researched the company months ago, even wrote them an e-mail to ask about a product specifically for microscope lenses. They are really small. They actually wrote back and said they will look into it. Microscope lenses are notoriously hard to clean, the glass usually being down inside a tube and not easy to get to with anything less than a Q-Tip. So I bought two sizes of pen for those, and the sensor pen for my camera.

I was merely trying to protect the innocent from themselves. Many of us on POTN field all too many, "I did (something stupid) and caused (some problem)...how much is it going to cost me to fix this, or can I try to fix it myself?" lines of inquiry!

I think Wilt has a good point, LensPen and SensorKlear are two different products and someone not paying attention could very easily do something stupid. The fact that Wilt read through the posts and commented on LensPen shows how easy it is to confuse the products when the correct names are not used.

Yes, however, they are made by the same people.

I just captured another movie, and found out the spots are still there too. Makes no sense, cause there is no iris in the microscope... OOoppps, wait, there is an iris in it, below the stage, and I have it closed down. It's weird, cause at 10x, there are no spots, but at 20x and 40x they are showing up again.

Which means the spots could be behind the filter. That's not good.

interesting thread.
i got a 1ds2 recently and found that there is a speck on the near centre of the sensor.
i only got a Lenspen and out of desperation, i tried it. i am aware that i must not touch the other edges of the sensor. anyway, i tried and got rid of the speck. I tried the blower first but it does not work.

cheers,

Well, I'll know Saturday or Monday if it works for me. It's scheduled for delivery on Sunday, which is absurd.

Unbelievable. Do you want to guess what it was? Think FAR OUT in left field.

My Lenspens, SensorKlean and FilterKlear arrived Saturday. I took a final shot of a clear area, to have a record of where the spots were, then took the camera off the scope. I got the Copperhill stuff ready, I got the SenesorKlean pen ready, I set the camera for manual sensor clean and went to work.

I cleaned the sensor first with the Sensor Pen, tested, it got some of the spots and made others lighter. I cleaned it again, using a little more pressure, it got some more spots off but their shadows were still there. I tried again, scrubbing back and forth, back and forth. Checked again, they were almost gone. I did 3 wet cleans, they were gone.

Put the camera back on the scope, took a shot, there were more spots and now an S shaped hair. Well, WTF? I cleaned it again, the spots were gone but the hair was still there. Wet clean, more spots, the hair had moved. Finally, I gave up, took some video, couldn't live with the spots or the hair.

This morning, I took the scope apart, cleaned every piece of glass between the base and the camera, then took some shots. Some of the spots were gone, but not that damned hair or the original spots that made me buy the Lenspens.

Took the camera off, wet cleaned it twice, scrubbed the sensor filter with the sensorklean pen and wet cleaned again. The hair is gone, the spots are gone. Took one shot, looked at it in EOS utility, the the sensor was clean. Turned it off, turned it on, opened EOS Utility, opened live view and the damned spots were back. In almost the same spots, but not quite.

Wanna guess?

The friggin mirror is throwing new lubrication spots on the sensor every time it flips up, and in almost the same places every time.
