Mea culpa, I mentally translated TTL to P-TTL, just treating it as Through The Lens metering in general. > > The AF540 is a good flash. It's P-TTL, which is the Pentax auto format. Why > would you want to use it in manual mode. So far, I've found three reasons to use my AF540 in manual mode, My K100Dsuper, my K20D, and to a lesser extent my K-x. Frankly, in my experience, Pentax flash metering technology lies somewhere between useless and destructive. Granted, it has improved a lot lately, and I have actually found several situations with the K-x that using p-ttl with the AF-540 has led to photos with nearly acceptable exposure. But, even if p-ttl were to work perfectly the question of why I would want full control of any piece of photographic equipment stuns me from a photographer of your ability? Do you just leave your camera in green mode and autofocus and let it make every decision for you? I didn't buy a DSLR because of how well it took photos without my input, I took a DSLR because of how well it lets me control it. -- Larry Colen l...@red4est.com sent from i4est -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
