24 Mpixels*12 (bit/pixel) / 8 (bit/byte) = 36Mbytes

Do any of you actually know the answer--like work for Sony?

I don't work for Sony but based on the compression ratios, my guess is likely it's a variant on LZW compression which is lossless. A lossy algorithm should net at least a 50% reduction in size.
