External flash for bounce flash (bouncing flash off of the ceiling) allows for much better shots with more consistent colours and no paleness in the skin. Plus you can also fill better in daylight. Definitely worth it. STICK WITH THE CAMERA BRAND. Flash systems rely on dedicated metering systems (i-ttl for nikon for example) and you want something that will be fully compatible. The FL-36 is what most of my Olympus friends use.Originally Posted by erikzen
