Sensor Cleaning
« on: September 30, 2016, 08:15:21 AM »
My A77 camera had a few dust bunnies and I have watched the Youtubey things on how to clean it.
I followed the directions and got it cleaned and it was really good to see that I now had the talent to do it.

Dust bunnies are a part of photography here, so its either buy a compact camera or learn how to clean your sensor.
SO I now know how to do that part of it and all was good in the world again.
I thin got more and I cleaned my sensor only to see I had more.
Cleaned it again and there were a few I just could not move.

We had to got the the closest city to us as it was where our son lived to so it was really good.
I booked my camera in to be cleaned and it cost $130 and they got them.
It was a job I couldn't do so I didn't mind paying out to get what I could do done.
So if you are like me always remember that sometime there are thing we know but we still need help.
I am sometime too honest for my own good.

Yes, cleaning sensors can be very disconcerting.

The A77 and other A mount cameras have an anti-aliasing filter in front of the sensor, so you are actually cleaning that, not the sensor. However damaging the filter is as bad as damaging the sensor. All the A mount cameras have a mirror in front that can gather dust that would otherwise go onto the sensor and cleaning that can often solve the problem. Proper cleaning will usually require that you clean both. Note that the A77 has a removable translucent mirror that is very fragile and does not flip up out of the light path like DSLR mirrors, thereby providing a small amount of additional protection to the sensor. In the event that you damage the translucent mirror, it is much cheaper and easier to replace than the DSLR mirror. Most A mount cameras have a setting that vibrates the sensor to automatically remove dust. In my experience it does not work unless it is just dust bunnies. Other dust, like pollen, can bake onto the sensor and require more force to remove, not easy!

Imagine the chance of getting dust on the A7 series cameras which have no mirror at all. In addition, the A7R and A7RII do not even have the anti-aliasing filter. :(

I did have to take it to a proper camera place to get it done as I treid so many times to clean it and I knew I couldn't do it so I thought it had to be safer for someone who know what they are about would be better to do this job and they were.
That anti-aliasing filter in front of the sensor that flips up. I have cleaned it early on.
When I say early on I mean in the 1 month of owning it. I cleaned it and it bent,I tried to fix it by going on the other side of it.
And I couldn't fix the buckle in what ever it is made out of and I did think I had stuffed it up.

I put my camera back together and went out and took a few shots.
The shots were downloaded and not one dust bunnies was there so I must have cleaned the sensor to have none left.
That flip up screen with the damage I put on it had made no difference to any shot I have taken with it then or even now.
I was going to replace it but it does nothing to the photos so I will save my money.

The clean mode when me camera was dirty didn't work. And this was done more than one time.
I did try a lot of times. So I like what I done as it was in my too hard basket.
But since then, we were on a trip away and I had ordered one of those gel sticks, which was at home when we got home.
So I may not have to take my camera away to be clean from now on.

AScot thanks for taking the time to give me your input I really appreciated it.

The anti-aliasing filter is glued to the front of the sensor. What you are talking about is the translucent mirror. As long as you do not stick a finger through it or bend the frame out of alignment, it should work fine. You should never touch the mirror as you may transfer body-oil to it and the oil will then attract dust, like a magnet!

I would have preferred Sony to make the mirror move up out of the way to make sensor cleaning a lot easier.

Having to do this manually would, in my mind, make people think again before investing in an SLT, I admit that I am having my doubts now about upgrading................

Gordon, it is as easy as pressing a latch; the mirror then flips up... it's spring loaded.
There are people who actually think LENS stabilization is better than sensor shifting!

Yep; flips up flat against the top of the compartment to allow easy access to the sensor while keeping the mirror safe and out of the way.

Of course one must STILL take care. Your friend Cholly was once cleaning his sensor and CARELESSLY stuck the business end of his Rocket Bulb into that compartment without regard for the mirror. I put a dent into that mirror when the tip of the bulb struck it rather forcefully.

I tried to get that dent out... but no joy. The camera still worked, AF and all, and there was no artifact in the image with MOST of my lenses attached, regardless of Aperture value.

The replacement mirror cost me $60.00 U.S.D.... not too expensive in terms of Sony spare parts, and installing it took me all of 30 seconds.

Lesson learned.

That spring loaded one is the one I put a few dents on and it hasn't made for bad shots.
I rather blame the operator than the camera on this area.

But the point of this is that I prefer to give up when I know I can't fix it.
As I know of people who will keep going and more than likely would cause more damage.
So its knowing when to give up and get proper advice.
I was so pleased with the results I got this time..

I did notice that it has been said that the replacement Mirror is $60 US.
Here in Australia its around $130 now, I will get it one day just not too worried about it due to I'm still getting good shots.

I plan, when funds allow, I will get he A77ii with battery grip and the Tamron 150-600, once its all together it will stay that way, hopefully a good way to avoid dust bunnies on the sensor...........
