For a consumer-grade camera, as long as you set the JPEG format to the
highest resolution, lowest-compression setting, you should fine. You'd be
unlikely to notice any difference between the raw image and the compressed
one. Any of the professional-grade digital SLRs should have an option for
saving the data in a "raw" format (which typically is actually just a
proprietary, non-lossy compressed format).

Actually, most RAW files are compressed somewhat, too. Read the instruction
manual.
