I wanted it just do not believe that you can do it with a brush at a 20+ - megapixel sensor,
but it's actually perfectly.
I've gotten a Sony Alpha 230, a Sony Alpha 390 and Alpha SLT 2 successfully made spotless with this brush,
where you have to fold away separately in the Alpha SLT nor the mirror, there is a bottom so snap hooks where you can fold down the,
to reach the sensor.
The brush and the whole operation "open-heart patient" is not for Grobmotoriker,
Anyone who does not trust the, should be better and give his camera in the Service,
all other technical and fine motor skilled a recommendation for this product,
because it delivers what it promises, if the user is used properly,
Buy!
