But yeah, the Pentax flash system is prehistoric compared to the sophistication of the Nikon CLS.
Last weekend I had normal cycle times, but this weekend was just painful. And truthfully, while the 540 is slow compared tomehta my friends withnikon, it was never this bad. I have always used lithium batteries in it because it gave me the best response time. I am wondering if I got a bad batch of lithiums, though, because this was just abnormal behavior for my flash. I was thinking of switching to eneloops anyway, so maybe this is my push.
All of that said, I would still really like it if Pentax introduced a new flash at photokina. If they don't I will probably sell the 540(as long as nothing is wrong with it) and switch over to Metz. I am also debating buying an led video light because many of the DJs in my area have been getting fancy with the disco lights and it is a real nightmare photographically. I love the ones that make everyone look like they have green chickenpox.
