    Re: Question about flash photography with a Chamonix

    Your LF lenses are agnostic to that branding. Nikon or Canon iis all about their TTL proprietary systems. Not an issue with LF shutters actually. Which I like. I purchased Nikon trigger for my LF lenses (shutters actually), just because I have a Nikon DSLR in case I want to user that trigger/flash with it.

    Re: Question about flash photography with a Chamonix

    The other little detail--just linking this thread with that other recent one you've posted on about light meters--is the flash illumination to ambient illumination ratio. This may not apply to you, but I use my flash in a blacked out studio at times. But also applicable I guess is when I'm using the strobes inside the house along with sunlight or lamps. I've discovered, being new, that I just can't have dim lights when it is time to focus. There is a certain amount of light that I need to accurately focus, and how do I account for that in my overall lighting? Do I turn it off prior to exposure? Assuming it is constant illumination (daylight or lamps of some kind), do I want it to contribute to the overall lighting? This is where your Sekonic (I use a used 558 for simplicity and because it's cheaper) comes in since it can show you whether your constant light is going to contribute to overall lighting, and to what percentage?

    Since I use 1200 watt second Godox monolights or two Godox (Flashpoint) AD200's mated together for a total of 400ws, I have realized (by checking that % contribution of ambient illumination feature included on the Sekonic) that a little constant lamp lighting for focusing won't affect the exposure...unless I choose to make it so. If using less powerful lighting and longer exposures, then the ambient (daylight or constant lamps) might contribute to the overall illumination.

    But to get specific on the flash trigger, I am using the Flashpoint R2 Pro MarkII 2.4GHz Transmitter. It uses the 2.5 sub-mini port for syncing to the lens (shutter), so my cable is 2.5 to PC Sync. PC sync is what most of the LF lenses (Shutters) I have seen are fitted with (some Graflex cameras use bi-poles). Then add whatever Godox/Flashpoint strobes you want. But the same would go with any system other than Godox.

    Thanks again for the detailed explanation.
    There's a lot to learn.

    Can I shoot with the flash connected to this lens?
    I wonder if I can shoot a flash with this Linhof / Schneider 150mm lens.

    You need to know if that PC is X or M synch. To do that plug your flash into the terminal. Point the lens at a blank wall and fire the flash while looking through the back of the lens. If you see a bright circle of light then it is synced for any brand electronic flash. If you don’t then it is only synced for M class flash bulbs. Check it at several different speeds to be save.

    Flash sync is controlled by the shutter.
    Flash exposure is controlled by the aperture.

    Just wanted to clear that up.

    For electronic strobe.

    For flash bulbs there are also exposure impacts for “faster” shutter speeds.

    True. OP is considering electronic flash, so just keeping it basic.
