    Posted: 09 December 2013 at 01:30
I noticed that I had a couple specs of dust on my sensor after uploading the pics to my PC. I did the normal dust removal procedure. Removed the lens, flip the mirror up and used a super blower to remove the dust. When I dropped the mirror back down I noticed there was a huge cluster of dust on the mirror too. ONE quick blow and the mirror was KIA. No! The super blower did not make contact with the mirror. The A99 mirror is a flimsy piece of crap.

3~5 weeks until I get my camera back from Tokyo. Looks like I will not have a camera for my New Year trip to Thailand if the body is not back before I leave. Looks like I might be shooting film this time.

I think a replacement mirror can be purchased, and I would think it could be shipped in less time. I remember looking into that for my a77, there is a similar (but larger, of course) part for the a99.

I don't know what a super blower is, but all SLT mirrors are sheets of very thin plastic stretched over a frame. They have to be handled carefully.

Maybe should have posted here before sending it out. If you lift the mirror completely out of the frame, your camera can do everything - and I mean everything - it did before except autofocus. Manual focus is better than nothing while you wait for a replacement mirror to be sent to you.

There was a spot showing up on the shots so it needed to be replaced. I have used the blower on my camera since I bought it in 2012 without an issues. I already knew to not use swabs on A99 mirror but I am surprised that a low pressure burst of air can damage the mirror.   

Camera shop could not find a listed part# for the A99 mirror. I sat there with them for 30 minutes looking at part numbers and parts drawings. Tech at the shop called Sony in Tokyo and was told they would let him know somebody by COB Monday (today for me). I left my camera with the shop yesterday. If Sony Japan will not send a replacement mirror the shop is going going to express mail the camera to Tokyo. I am on an island 1000 miles south of Tokyo with most of that distance being over water.

The best part is I have a US model but Sony Japan said they would take care of the repair for me. Without express mail service the turn around time for the autofocus assembly on my old A900 was 17 days. Most of that time was spent waiting for parts.

I have an A700 plus my Minolta 8700i so I am not camera-less.

this is kinda freaking me out. I just browsed through the Knowledge Base sub-forum and didn't see any "How-to" on cleaning SLT mirrors... is there any threads on this? Perhaps with pictures?

It's normally not a big deal. I personally lift dust particles off with a tiny artist's brush. I have also cleaned a fingerprint and similar residue using a cotton swab - but with no pressure applied. The main rule is to handle the process gently.

I cleaned my A55 mirror along time ago. I don't have it anymore but, I removed it from the camera VERY carefully. I used an Eclipse dampened Pec Pad folded over twice and lightly swept it over the mirror. It cleaned it good but what a pain in the a??
There's a very good chance you will scratch the mirror if you don't totally prepare yourself for it and have confidence when removing the mirror and putting it back in. Use nitrile or a surgical type gloves so you don't accidentally touch the mirror.
I don't think a lightly scratched mirror will affect you IQ.

I have removed dust off of the A99 mirror/sensor many times without any issues. I have also cleaned the sensors/mirrors on my past cameras (A100/700/900, NEX3/5) without any issues.

No physical contact was made with the mirror. The film mirror is a cool "concept" but not very practical. Definitely looking forward to the release of the mirrorless A-MOUNT fullframe camera.

In the left-hand column on most pages under "Articles" there is MiPr's "Cleaning the sensor in your camera" -- see.

That's fine for cleaning your sensor , which the article is about , but don't clean an SLT mirror the same way .

The only time I have cleaned an SLT's mirror , just a standard blower bulb did the job.Needless to say I was carful not to touch the mirror with the tip of the blower .

How much force would be required to damage the mirror with air pressure alone , I don't know.
I would have thought that unless it was touched , and you didn't use compressed air , then no harm would come from it.

It would even do autofocus if Sony had decided to add CDAF - at least with SSM/SAM lenses. The implementation is there (feature exists in A560/A580), I never understood why it's missing in the A99. Take the mirror out in bad light, and you get an A7-like low light capability.
A99, NEX-C3, HVL-F43M, more than enough glass (A, E, M42, MD)

My bad. I got so engrossed in finding that article I forgot that what was really needed was one on SLT mirrors.

Does anyone want to write one? See.

Camera will be returned to me in mid January.
I wish I wouldn't have sold my A900 now

I am almost tempted to leave all of my gear and just use my fiancee's Nex-3. This way I can give her more instructions on how to use her camera. She has a great eye but sometimes doesn't pay attention to the settings.

Just got back form the camera shop. I requested that my camera be sent back to me since Sony was going to charge me for 2 hours of work when the mirror can be changed in less than 10 minutes.

I found a source for the replacement mirror I am going to order PN A1903073A and do the repair my self. Savings will be about $400. Camera should be in my hands by wednesday and hopefully the replacement mirror will arrive before the 26th. If not, I will just shoot MF and that doesn't bother me a bit.
