AF400FTZ or AF-360FGZ TTL with Pentax 645?
Anyone know if either the AF400FTZ or AF-360FGZ are compatible with TTL flash on the Pentax 645 (the original manual focus one)?

Anyone know if either the AF400FTZ or AF-360FGZ are compatible with TTL flash on the Pentax 645 (the original manual focus one)? The 400 is. The 360 (doesn't have TTL, only P-TTL) isn't. G

AF400FTZ or AF-360FGZ TTL with Pentax 645?
It is curious that the 360 seems to work, I'll be interested to hear how the pictures come out! Now, of course, I'm sitting at a table surrounded with bodies and flasguns trying out all sorts of combinations. My late 60s vintage Pentax flash works a treat with everything including the DS but I'd lon...

Thanks... I've looked those up and they look exciting, although I'd rather not replace my 285 with something unless it's a really nice flash. I'll buy the AF360FGZ when I win the lottery, but the 285 is the best flash I can get with no (E-)TTL, I reckon. I suppose my question has changed to: ...

it's very hard indeed to find qualitative descriptions or even pictures of the beam and its effects That's probably because you'd need two cameras, and probably a good sense of timing - as the AF beam is only flashed up for a second or two. On the AF360 it's a red and black grid. Bit like a bar-c...

Hello everybody, I've also been pondering about this, because I find the AF-assist (AFa) incorporated in my K10 to be at least annoying because of the potenial distraction generated by the strobe flashing and on top of that cumbersome when having to use it when needing AFa, but not wanting to use...

Wow - we have related careers: I'm an undergraduate biomedical engineering student, and study a lot of optics (and many hours of medical imaging a week next year). The Metz 50 MZ5... so it's compatible with the Pentax hotshoe and will flash its AF assist at an appropriate time? Does it do P-TTL m...

Hello Jonathan, First of all thanks for the compliment regarding my flower. I think very fortunate to be abled (and allowed by my department head) to use this energy spectrum for my photography hobby, not many are. Regarding my Metz flash, it isn't PTTL-compatible, but I don't have to use it ...

I heard somehwere else that the hotshoe sends out a voltage no matter if there is a flash on there or not. I have the 540 flash which works with just the beam when you set it to Standby. I am not sure if the camera knows if its on SB mode or if the camera just ignores it. I remember reading th...

Question
One other question, what the hell is P-TTL. Seen the word everywhere, and theres a guide to it in this forum, but what is it?!? It's where the flash emits first a small flash, during which it measures the light coming back and then sets the flash output for the main flash, which takes place a very ...

Question
It's where the flash emits first a small flash, during which it measures the light coming back and then sets the flash output for the main flash, which takes place a very short time later By the way, just to be clear... It's the camera that does the metering based on the pre-flash's reflection th...

taking photos in the dark
Just bought a Metz 58 AF-1 and finally found some time to try and get to grips with it! Decided to go out into a dark field with the dog (yeah you guessed it, that's not actually me on the left...that's him) and see if - 1: I could get him with the tele... and 2: I could set the flash up as a slav...

K10/Tammy combo failed to lock onto anything in the dark (murk). How do you take pictures in the dark? Surely . . . you need a K9 . . . sorry, couldn't resist. Fact, your camera cannot function properly in the dark, any more than a cat can see in the pitch black, a common myth. Fact, your came...

I have taken photos in pitch black with my K10D and the built in flash. This strobes to light the scene and aid focus. I assume a compatable flash should do the same thing. The red grid I am aware of was I though, infrared, and I believe the K10D can't see infrared though I might be wrong.

The flash certainly should give you a red AF assist light, however it seems to be the camera that requests the flash to do this, and the K10D seems to me to be a little reluctant to make this request. If I put my AF540 on my old mz10, it will use the AF assist light for pretty much any scene wher...

on the one hand, I think it's not the best way to invest your money or time... you could use a pocket flashlight (torch), or a shoe mount video light... or just focus manually.... but since I admire determination... here's an idea.... get a small led torch (one of those with three led's)...

Wow! great response guys, thanks. I was just messin' around in order to learn the equipment. the focus issue was with the flash on the camera and I think Mannesty was correct with the green absorbing it., plus the ground dropping away. The metz grid definitely works as I saw it perfectly across my...

<snip>I did my first product shoot at a client's with the Metz 58 today and the wireless light sensor was less than reliable. I am still getting to grips with it, but it seems to need to be pointing right at the camera and quite close, (10 feet) although it may have been something else.</sn...
