Cleaning the mirror on A77V

[sjhughes]

The mirror on my A77 has what appears to be a small spot of grease on it.  This appears on photos where it is on an area of bright sky as an out of focus grey spot.  Can anyone suggest how to clean the mirror without damaging it?  The only cleaning instructions in the manual refer to cleaning the sensor.

Hi sjhughes

Sony warn against touching the a77's mirror, and I can only reaffirm that note of caution. It's very easily marked and should be treated with at least as much care as the sensor beneath it.

The reason you see the spot on your images is that the mirror is of the 'pellicle' type which remains in place during exposure. This is the primary reason why you should never touch it, as it lies in direct path of the image and any/all marks on it will show up on your shots to some degree.

Treat it as you would the sensor: dust may be dislodged with a blower brush, but if you have something stuck it, take it to a decent camera store and get it professionally cleaned.

If you need advice for removing the mark from your photos, just ask

Cheers

Mick
