I have a Kodak Commercial Ektar with Synchro Shutter that I would like to use with both flash bulbs (m) and modern electric flash (x). The lens/shutter assembly is equipped with a bi-post and a dial that lets you select the type of flash being used i.e. (m) flash bulbs, (f) fast, and (x) electric. I will use this lens on my 4x5 field camera but for the purposes discussed here it will be used on a modified Speed Graphic press camera. The camera is equipped with a vintage flash gun that takes 25 and 25b bulbs. I am making a mountable flash mount that will house a modern electric flash via hot shoe. I would like to be able to use both flash applications (bulbs and electric) with this lens. Excuse my naivety but I am accustomed to using flash bulbs on this camera with a different lens assembly by connecting the flash gun via an ac plug with a bi-post connector (male connector) to a solenoid (fixed to lens board) with bi-post receiving holes (female connector) that is connected to the shutter lever and engages the shutter when the button on the flash gun is depressed. In order to use the Ektar with my flash gun do I simply get a different chord with a female bi-post connector and connect it to the Ektar's male bi-post and fire away or is there more to it? I do have such a chord but it is brittle and falling apart so I can't really use it to try. I've connected this cord to the flash and the lens but when I depress the button on the back of the flash gun nothing happens with the shutter. In regard to electric (x) flash, how do I use this lens with the electric flash that I plan to mount to the camera? I assume I need a bi-post adapter or adapter cord that will allow me to connect a regular pc cord to the lens. Are these difficult to find if this in indeed the solution? Also, does this work in the same way as it does using bulbs and the other lens connected to the solenoid i.e. connect flash and lens via cord, depress button on back of flash gun and flash goes off and engages the shutter simultaneously? If someone could offer some insight it would be greatly appreciated. Thank you!
