Sensor cleaning .. I did it!!
« on: January 08, 2013, 04:00:32 AM »
I've been to scared to wipe the A77 sensor and been plagued for a few months with some nasty dust bunnies. I was encouraged by Gordon who said it was easy. Thanks Gordon!! 

The other day I went out and took a sky shot at f16 first. See what I mean? Now, I'd never shoot at f16 in the field, but you get the idea...was not good. Ad I'd let this go on for too darn long.

You can see the difference between f8 and f10 in the two geese photos.

So I purchased this sensor cleaning kit and after reading and speaking to the camera store guy, I just did it.

Worked like a charm. Pretty pleased.

Photos are self explanatory.

Clive

Thanks for the info Clive. So far I have been impressed how little dust my 77's have gained. The mirror seems to act as a permanent barrier :) I think however I will buy one of these kits just to have handy.

Do you clean the SLT sensor any differently from the one in the A700?  I gather the mirror is meant to be more delicate in an SLT, and that care needs to be taken in cleaning it.  Did you find that?

I don't currently have any dust bunnies on my A77's sensor, but the camera's very underused at the moment. I bought it in August and it still has less than 1000 activations  :-(

REX ;) "My friend Clive we have telepathy" ;)

Thanks Gordon, I needed a boost. I've talked about doing this for a while and just had to do it.

Bluebear said. "I gather the mirror is meant to be more delicate in an SLT, and that care needs to be taken in cleaning it.  Did you find that?" Ah, I never cleaned the mirror (other than a few gentle blasts from the digi-blower), but was thinking it maybe had to be done with the swab. I tried to clean the sensor with a blower and it never got the bad pieces, so I was thinking the mirror was the source. It seems not. I have cleaned the mirror with a blower and watch a video about it. It seems stronger that we are led to believe..it actually temporarily bends when the air blast hits it.

Anyway, you just manually flip up the mirror (there is a latch) and the sensor is exposed.

So after three DSLRs, I did this deed. Seems painless. I was not happy about having to touch the sensor. Guess I should do he A700 now. ;)

I remember cleaning my A700 sensor a couple of times, so guess the A77/SLT is the same process.  When I need to, I'll use by rocket blower on the mirror--gently!

The A77 is a bit different. With the A700 you have to set the camera in "clean mode" or whatever it is called so the mirror flips up electronically and exposes the sensor.  With the A77, the camera can be off and does not need to be turned on. You remove the lens and manually flip up the mirror by releasing the little latch...the mirror is spring loaded and flips up on its own and you see the sensor as before. Just snap it back in place when done.

I've been using VisibleDust products for quite some time now. I've never been disappointed with the results.

I too have learnt something new reading this,I did not know about flipping the mirror up manually with the power off,its good to know in advance.

I occasionally give the sensor on my A700, and Jans A350, a blow with a rocket blower, and then after a while check for dust bunnies by doing  what Clive did and take the required action

I used similar kit but named Green Clean to clean my A200 and wife's NEX5 last year. It didn't seem too complicated.

"I did not know about flipping the mirror up manually with the power off,its good to know in advance."

Just in case there is confusion, this is only in the A77 .. not so the A700.

Thanks to all. I have to tell you this made me very nervous. I remember way back when we were warned about going near the sensor and if it needed wiping, then send it away.

So if you have stalled on cleaning the sensor with a swab, fear no more.
