Strange that there are different sizes.

Thanks!

It isn't surprising to me. The A77's RAWs will vary in size slightly from one image to the next. The files, despite not being labeled as such, are really a form of compressed RAW. The other thing that can cause a slight variation is any extra information the camera is storing alongside the RAW image information (Lens corrections, GPS coordinates, etc.). Also, don't forget that RAW files usually have a very small sidecar photo that is in a JPEG/JFIF format for quick preview. That can cause the file size to vary a bit as well.
