Originally posted by Digitalis This is actually a limitation of the camera shutters pentax have been using - not a flash system limitation per se. I can get my Pentax K5IIs* to synch at 1/250th, though what you end up with is this:
Pentax cameras don't send an electric signal to the hotshoe at shutter speeds above 1/180, thus the trigger does not fire, I find it annoying that an engineer in Japan 30 years ago decided how far I can push my camera, if I want a black line that's my own business, and 1/180 balancing ambient light and doing motion stopping stuff easily becomes too little
Quote: Why would a Pentax flash need this? the trigger voltages on modern flash units are quite well suited to cameras - there isn't the wild variation that you would see in the mid 80s where some flash units would use triggering voltages as high as 800 volts.
Sorry I didn't express myself in the right way, I was talking about thermal protection, I have an external pack for every speedlight I own, I don't go railgun mode but frying a capacitor is always an option.
Quote: This only really makes sense for metz and other off brand flash units where cross system compatability is essential and occasional bug-fixes are needed.
what about putting hand to to p-ttl logics and updating camera and flash units just like camera firmware like for ex. AF?
Quote: I haven't found this to be a problem with my wildlife photography:
Well I guess you don't use what 's not there, it's always about possibilities
Quote: Even if you use off brand wireless flashes you still have no wireless control of flash power output, and even with Nikon CLS you have to deal with a rather annoying menu system when you want to change anything. Elinchrom allow you to control flash units (BRX and Style RX only) from an Ipad or Iphone, I find this to be a great solution because the interface on a tablet PC or smartphone is miles ahead of any camera.
well since we have none of these options here what shoul I comment?
yeah menu systems are annoying better to eliminate them for good...(?)
Quote: Prehistoric you say? - have you ever had to use one of these with an AF540 for AF360 flash?
I know what that is for, still where're talking about basic capabilities
Quote: I agree with this complaint, however it is possible to modify an AF540 with a plug so that it can be used with these systems, though such a modification would in all probability void your warranty, and not many people are comfortable opening up a flash unit. Or you can simply buy an accessory shoe with the required plug on it and keep your warranty
I know, I wrote it...
Quote: * in a nutshell: I got my Pentax K5IIs and linked the shutter release remotely to my Nikon D4 which was set at its synch speed of1/250th which in turn triggered my studio strobes - I had to carefully compensate for the differentials in response time between the two cameras but when I got them to open their shutters to open in perfect sync with each other at 1/250th, I simply had to fire the flash and that was the result that I got.
Sure... we all own other system cameras to try even more workarounds....
Maybe we could go on for weeks, but I think I'll just forget about it, someone pointed out the real deal, there is no degree of innovation whatsoever, is really weather sealing more important than a 3.5mm jack,
a battery meter on screen, thermal management, settings saved at power off, grouping etc...?
We have a 20years old project inside a condom with "exceptionally fast battery recharge time of 5 seconds" (OMG this is almost incredible!! Oh wait, what about flashes recharging in half the time without external packs???) and we're alla sitting there with our jaws opened...
Everyone can judge for themselves, quoting someone else, maybe at pentax they've just weighted their users, and to most these features don't mean a thing.
My 2 cents.
