Oh, I'm not complaining about the results I get at 1/125, it does work as expected. Its just that every one of my other Pentax bodies (8 in all) allow me to set them to X sync; either by an explicit X position, or by virtue of the fact it is a 'standard' shutter speed, like 1/125 etc. I was just suprised that there is no way to set it to 1/150 at all. It does select that with an external dedicated flash, just can't do it with a PC connection. - Peter -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
