    Posted: 21 June 2010 at 04:25
I picked up my camera with the 70-200 mounted and noticed the viewfinder was VERY dark and I was only getting shutter speeds of 1/160th of a second at 200ISO and f4 on a BRIGHT sunny day. I was confused.

As I started to take pictures, I heard the sound of a motor whining as the mirror came down, viewfinder was still very very dark. Almost like I had a 8x ND filter on...Every exposure was making this whining sound and the exposures were going down to half a second in broad daylight.

Then it happened.

"Camera Error" on the LCD and "Err" on the top LCD, the camera locked up.

And every one or two shots I would get this error, and the body would lock up, now I'm getting nervous as I'm about to step into the pace car for a bicycle race happening in 5 minutes, the wife of the pace-car driver had an a100 so I thought that might be my last hope.

So it turns out, if I shot at anything past f4, the camera makes a whining sound, slows down the shutter and locks up.

Then I tested all my lenses, it does this no matter what, it's a body problem, so I pushed the depth of field preview, and again! Anything past f4, the blades stop down to the smallest aperture, like f22-32. Camera locks up, I have to restart and then sometimes even take the lens off and mount it again to open the aperture blades.

THIS IS BAAAAD, I have a bridal shower and g20 protests this coming weekend and a wedding in July.

Anyone have this problem?

p.s. If you want to see my pics btw, they're the last three in this slideshow. http://bit.ly/aw0yXc

Sorry to hear that as crap like this always makes me cringe.

I have an a900 and I have not had this issue.

Good luck!
Regards,
Bruce.

my a300 had the same problem.......I realised that it only occurred with the mino 50 f/1.4. On further inspection, I realised that the lens had oily blades that caused it the jam/stick when one closed the aperture. I got the lens repaired....the problem is gone. Could this be your problem too?

Nope, it happens with any lens.

I know Sony will say it's my lenses, that's what they said when my a700 was malfunctioning.

Unless they want to suggest my 17-35, 24-70, 50mm and 70-200 all got oily blades at 3pm on June 20th. LOL.

It's definitely the body.

Sounds like aperture motor has issues. You may want to find the warranty papers
Sony + Minolta + NEX stuff...

You might be able to fix this yourself.

Take a look at the lens mount. The aperture arm has probably gone slightly out of wack mounting or unmounting a lens. Wobble the aperture arm and you might be able to fix it. Don't apply unusual force doing this!

I second the suggestion to check aperture lever. I had the same problem once and fixed it myself :)

Yup, aperture lever. Rent a replacement, send it to Precisin Camera for repair. Contact msoars here (Mark Soars). He'll fix ya up! (He did a great job for me).

Same here, and after that the problem never came back (yet).

Does Dyxum have a section which includes a database of these issues and potential solutions, or could one possibly be created.

This sounds like two distinct problems with the aperture lever, and I've read of other quick do-it-yourself fixes for other issues.

It would be great to have a section as a first point of call with descriptions of problems and possible solutions.

This might also include 'fixes' that just need settings changed, as the problem descriptions might be similar

Wow, I should have counted the amount of camera dreams I had last night.

At least I woke up to a solution on this thread!

the pulleys that the aperture actuating ring rotates in are made of a soft rubber / plastic. They're white and there are two of them. One, around 2 'o' clock, another around 5 'o' clock.

The rail had slipped out of both, I popped it back in the lower one, but the one at 2:00 looked damaged, a pair of fine tweezers from my wife was able to pull the lip apart and I had to pull the lever away from the ring to relieve pressure, popped it back out and moved the rail back in... Seems to be working now...

Thanks for the tips everyone...

Puddleduck: I had to use some force :S

I admit, there was a time where I was changing lenses and my 70-200 went on kinda funny, so I removed it and remounted... This is a bad weakspot for press guys who sometimes need to change lenses while running or doing other tasks...
