Sensor Cleaning
« on: May 11, 2009, 01:40:53 AM »
Im rather positive I have seen this thread before but I couldn't find it.

A little guidance please in cleaning some dust on my sensor. I don't have any cleaning kit with me. Only thing I have is a brush that came with the 7000 i bought to get the 50 f1.7. Can I use that?

Many threads to catch up on for this. Maybe start with:

And from that:



Have a look at these older threads for some ideas and solutions...

Basically a rocket blower is a cheap and very worthwhile investment, and it the first step in cleaning a sensor.
After that there are a variety of brushes (butterfly, dry, wet) and swab methods to work through.
Then more expensive vaccuum type systems (to be used with great care).
Then as last resort, camera shops servicing departments.

My personal experience:
I've had dust on sensors many times. 9/10 times the rocket blower is enough.
Rarely I've used a dry brush, once a wet brush. (tried a butterfly, didn't like it - probably should sell it really).
Never needed servicing

The Giottos Rocket blower is very affordable (for those in the UK, I got one in Jessops recently for £7.50; it was packaged as Jessops', but was the genuine article) and does a heck of a job, far better than any blower-brush I've used and without touching the kit.

That is one thing I don't mess with. 1 mistake and you have a expensive paper weight. I have used my air compressor on 15psi a couple of times but if that doesn't work my local shop does it for $30 while you wait and they assume the liability.

I agree with mphotoservices here. UNLESS you know EXACTLY what you are doing, I would leave well alone. Your alpha has quite a good cleaning system, although make sure you have a fully charged battery before activating the cleaner.
$30 is a lot less than $200.

Well- I clean my sensors pretty much weekly. I use a blower (but rocket blower and NOT compressed air- this can be very dangerous!), sensor swaps or the arctic butterfly thingy that works a treat. I think it is less harmful as one thinks. IMHO the idea of sendin git in for cleaning was a money making machine for some people. If you do it correctly I can't see anything that could go wrong?

I have not had to use anything other that a rocket blower on my A700 yet, but this is done probably 2-3 weekly.

Have used the wet swabs before on the 5D and 7D and as Stef says, if done as carefully and follow the instructions (if it says only use the swab once, it means only use it once) then i too, wouldnt have any qualms about doing it myself.

I have got into the habit of using the blower everytime I swap the lens - seems to be okay.

I would NOT recommend any compressor as it will add moisture as well as air, even with in-line moisture traps you will get some.

Hello all I bought a lensepen sensor clear last year and have cleaned the sensor on my a700 quite a few times and unless you are heavy handed or have no practical ability (no disrespect intended) it is a very simple operation it just needs a light touch and a careful approach

I've said it somewhere else before. I got a kit from Pentax, with a sticky foam head. I place it gently on the sensor and carefully take it away. Any dust spots that were on the sensor are stuck to the head. No problems.
