Pentax 645N and TTL

[Shootar401]

Before I go and dump some cash into a remote TTL flash setup, does anyone know if the Godox XProP TTL transmitter (with a few Godox TT600 Thinklite Flashes) is compatible with the Pentax 645N? ObviouslyI can't use the HSS with the body, but I'll be using it indoors and in the shade outdoors without a strong back light.

I figure Pentax TTL would be Pentax TTL regardless of model, I just won't have access to the newer features, which I don't need anyway.

You might tease up more response if you add a reference to the Godox XProP TTL transmitter in the thread title - it would most likely take a moderator's intervention to do that.
By the way, the moderators are unlikely to see a request buried in a thread, unless they happen to read through the thread because they are interested in it. To draw their attention to something, you need to "Report" your own post, and then make your request in that report.
I know there are a number of Pentax specific resources out there. They might be able to answer the question about whether your camera's TTl connectors work the same as other Pentax cameras' connectors.
I know that that is not the case for the (non-Pentax) camera systems I use.

You might also want to check out pentaxforums.com in the ‘Medium Format’ forum. There are several users there that shoot a P645 in a studio setup, so they may be able to help.

The TTL that comes in film cameras is ENTIRELY DIFFERENT from the current xTTL found in digital cameras today!

Film TTL uses a sensor in the TTL body to measure light send from the TTL flash and falling onto the film plane, and when the light is measured to be 'enough', the body sends a 'Quench' command to stop the flash from sending any more light.
Digital xTTL uses an xTTL flash that has 'preflash' capability, the body then reads the amount of light seen by the lens, and then xTTL body it sends a 'Output Predetermined Amount of Light' command to the xTTL flash a moment before the shutter opens.

Many (but not necessarily all!) current digital TTL flash units can be put into film TTL mode, so it can accept the 'Quench' command from the TTL body.
