Hello Nigel. Could you elaborate a bit ? Do you mean that PTTL does not take into account the ambient level?
Sorry for my ignorance about how PTTL works, I really only use PTTL with my on camera flash when I need to fill something; I just fire and it seems to work. My assumption is that PTTL needs to know then ambient light level, and that it will add enought ligth just to get a 'correct' exposure, that is, something not too dark, not too light, without too many burned or black areas, etc... But I understand that the light from the flash is added to the ambient light to get an acceptable exposure.
Originally posted by Dericali I guess I could consider a bracket. Or look at one of the Yongnuo flashes that offers TTL. Or a Pentax one...
Brackets have been discused a lot, and mcgregni pointed to a good discussion.
In my usual setup, I have a PTTL flash on camera, just for fill if needed; then a trigger with a little sync cord to my camera's sync port. This way I can control flashes off camera; only manually without HSS or PTTL, but it's ok for me.
But now the problem comes: how can I hold the trigger ? My hotshoe is already occupied. My solution for the moment is to use a light bracket where I put my trigger, while my flash is still on top of the camera. I can't use velcro or elastic bans (like magmod ones) to attach the trigger to my camera or flash.
I think there are three solutions for trigger and flash on camera (I'm talking about Cactus or Godox devices):
A. Use a transceiver, so you put the transceiver on your camera's hotshoe and then your flash on top. You get problems like added height to your flash, tension on your transceiver on long term, radio communication problems (yes the flash is on transceiver's hotshoe, but you communicate via radio). I think that this way was tried without success, Search the post from BruceBanner and others.
B. The tipical bracket to put your flash there, trigger on camera's shoe and flash controlled by radio. Mixed experiences here, some users find the bracket comfortable and others not. I think Bruce found communication problems with this configuration.
C. A flash with transceiver capabilities. The ideal solution for me, but still doesn't exist fully implemented. The idea is a flash dedicated, so you can put it directly on a Pentax camera with PTTL support. At the same time, the flash is a transceiver so it can control other external flashes. This way you forget about having a bracket or two decives (flash+trigger). The flash should have a convenient display and controls to manage external flashes with ease.
I know that the RF60 is also a transceiver and can control other RF60's, but if you put on the camera's hotshoe you, can use it only in manual mode (not bad, anyway).
On Godox land, we have the TT350P (a PTTL flash with an internal transceiver), that I'm considering. But I see it still a bit lacking in power and about controlling external groups, you can only see one group at a atime, and it doesn't seem too easy to enable/disable groups or the main flash. A V860II-P should be the ideal flash for me, but no idea is Godox is going to develop one or not. Meanwhile... I will use my bracket just to hold my trigger
