Igor, Here's all I know. I've got a TR power pack II for the AF-500 FTZ. I don't believe it is compatible with the AF-540 FGZ, but I don't know what is (sure wish it was). The power pack takes heavy "C" size batteries, and acts like it has infinite capacity. I haven't been able to wear it down or slow it down. I think you'll overheat the flash first. It is too heavy for mounting on a camera unless you are a gorilla.
The TR Power Pack-2 is *NOT* compatible with the AF-540FGZ. It was "specially designed to be used with the AF500FTZ Pentax flash unit."
There is a TR Power Pack-3 for the AF-540FGZ. -- 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.
