I told a camera technician that I've used and seen tutorials of people using air blowers to clean their sensors and he told me that anyone that does that is a idiot.

What's your opinions on this?

Thanks

I'm an idiot. I use Q-Tips, rubbing alcohol, and my air compressor to clean my sensors, and while I may be an idiot I haven't hurt any sensor ever by using my techniques. Sadly, skill and intelligence hasn't trickled down to most people, the people who are afraid to sneeze next to their camera because they think the world is going to end.


There is a protective film over your sensor, you're cleaning that, not the sensor. As long as you aren't pouring water into your camera, and you're not pushing down at 2 tons of pressure, you're probably not going to do anything to your "sensor" except clean it. The worst thing you're gonna do is put streaks on it with whatever you use to clean it, which means you'll have to clean it again. Oh dear God, what ever will you do?? I've used industrial solvents on optical coatings and camera sensors that cost more than most peoples entire gear list, and so far I've never harmed a single thing.

But again, I'm an idiot, so what do I know. All of my images come out blurry and streaky because my sensors are so crippled by how I clean them. It's terrible I tell you, I should be stopped.

Ask the tech about this statement which came right from the Canon Europe site (http://cpn.canon-europe.com …_image/sensor_c​leaning.do (external link))

Cleaning the sensor
Whatever precautions you take, one day the sensor will need cleaning. Canon approves only two methods. The first method you can try yourself using a rubber air blower. The second involves sending the camera to a Canon Service Centre.

Well if that makes u an idiot then i must be a idiot too. Maybe we'll find someone that isn't idiot.

But these guys are idiots for sure!

Assuming you mean a squeeze it bulb blower, not stronger, he could mean you are just driving the dust in the corners, but he could also mean you drive dust onto the AF field lens or could damage the shutter curtains, even though they are drawn back to expose the sensor.

In any case, I only puff in there with the lens mount facing down. If that doesn't remove a fiber or something, out comes the Arctic Butterfly. Last resort is a wet clean.

In any case, I wouldn't blast around in there indiscriminately and certainly not use canned air or the like.

I'm an idiot! Been one for years now. I use a loupe with lights to look inside my camera at the sensor and when I notice it getting dirty I use a specialized blower designed for sensors. Each cylinder only lasts me through one round of cleaning, but it does so without the hazards of other canned airs.

I also have a mirror and sensor brush but don't use those much sense my air and swaps seem to do the job well. Only problem was once I touched some lubricant on the side that I smeared on the sensor, but a few more swabs took care of it.

Believe me, I am very careful, so I'm a cautious idiot.

Thanks for clarifying that.

I suggest you find a "proper" camera tech instead of a "camera mechanic".

I wouldn't bring my camera to that "technician".

I don't recommend canned air. You will more than likely end up blasting the dust onto the focus screen... which is more of a pain to clean.

I would never used the canned air meant for computers. The blowing needs to be gentle, and those compressed air shoot out ice.

I would agree with him!!! BUT>>> you are not cleaning the sensor you are cleaning a piece of glass covering the sensor.

I will bring my camera to my "day job" every once in a while and our "compressed air" system through out all the labs is actually nitrogen. I will set the sensor clean setting and gently blow it out. And blow off the rest of the body.

I hope your nitrogen system is well maintained - it's not uncommon for systems like that to be capable of having aerosolized oil dropets in the stream. Either the system or you should filter it first - otherwise a wet clean (or two) will be needed to get the oil off!

Even though it's not the sensor, the surface is scratchable - but you need tiny grains of sand and a swab pushing hard dragging it across to make that happen. Luckily the sand particles are the easiest to dislodge with a blower - before a wet clean.

I use a brush often because it's so easy and effective.

I use my blower with the lens mount facing down as well and haven't had any problems yet. I also use the Arctic Butterfly 724 when necessary or the sensor pen. If all fails I use wet cleaning with Visible Dust products.

But mostly just the blower so that is why this thread intrigued me.
