SLT A57 RAW file quality, is it good ?
9 months ago

Hi ,

I own a Sony SLT A57, this is my first camera. I have been using it for about 8 months. I am an armature in photography.

I am using RawTherapee to process the RAW files. One observation is that there is lot of grain in the RAW file even at low ISO as 400 or 800. Is this normal ? or Is my camera defective ? I have seen RAW files from cameras like Canon 500D, Nikon D5100 (in similar light conditions & similar ISO). They look better. But in SLT A57's review it is said that A57 has got good RAW file quality.

Could some one guide me on this.

I have attached one of the RAW file from my camera. The lighting was not bad when i took this test snap.
