Subject: Flash issue (was: The first DS impressions)




My experience (with *istD + AF500FTZ) is that if you set P mode on the camera, the lens will be automatically stuck onto f/5.6 (even when using say f/1.4 lenses!) and flash exposures will turn out acceptable. If you try using faster apertures (e.g by using Av mode), the pictures will be hopelessly washed out. Looks like the camera TTL is unable to control the flash output and overcomes that by controlling the lens aperture (just a guess). This happened with 2-3 different cameras (*istD). Not tried the *istDs yet.


Anyone having such experience? Any advice for using fast lenses in order to increase the flash range/reduce recycling time?

Pentax adviced me to use an older flash (AF400T, AF280T) featuring auto (non-TTL) exposure ;-( Clever, isn't it?

My experience with the istD TTL flash control has convinced me to use a non TTL flash with the camera. The exposures in TTL are hopelessly innaccurate.
