Yes, I expect since TTL isn't supported on the K10D, so it does fire at full. If you can find out the GN at ISO 100 you should be able to work out your own flash table from there. The ISO 100 GN in Meters as published by Pentax for the AF220T is 22 so to get the correct aperture you need to

I admit, I'm useless when it comes to using flash. I use it as little as possible. When I do, I just stick the flash on the Canon and it all magically works - even on the G9 (tho the flash is bigger than the camera!) I don't remember having any problems with the MZ-S and 360FGZ That's the magic of

Since I almost always use the shortest or longesst focal length on my P&S, it does not seem imprecise, but it does seem slow. However most point and shooters I know are using their celphone can could not care less about a "real" camera. Graywolf (Tom Rittenhouse) Website: http://www.graywolfpho

Power Zoom is quite useful on big, heavy lenses such as the FA* 80-200 (and even more so on the 250-600); you can zoom over the full zoom range with only a very small hand movement. It's certainly not an essential feature, but it does have some uses. On Fri, Jan 11, 2008 at 03:48:53PM -0500, A

Pentax got the idea from Minolta, who introduced their wireless flash system, complete with moronic channel selection, in 1992. Given the peculiarities of the P-TTL wireless system, I halfway suspect it might be a licensed version of Minolta's ADI metered TTL system. The two work (And don't work)
