I am considering purchasing a SCA adapter and SF58 to go with my multifunction grip. I wondered if anyone in the group has experience with the Quantum Qflash, and if they would recommend its use with the M240. Which flash would serve me better for portraiture, and macro. (I also have a Nikon system, including SB900, SB800 and SB29). Thank you for your advice. John
Question: Why do you need a SCA adapter? Doesn't the SF58 TTL work directly on the M240? I have a pair of SF58 speed-lights for my S2, but do not have a M240 … so I wouldn't know.
The M240 multifunction grip gives you a PC port so you can use a TTL flash in the hotshot and still hard-wire a PC cord to a strobe. However, to use any radio transmitter, you'll need a grip bracket so you can mount a radio transmitter on it, and connect it to the multi-function PC port.
The classic mobile set-up is a TTL flash in the hot-shoe for fill, and a battery powered strobe off-camera as the key directional light. I use this mobile set-up 80% of the time.
Canon, Nikon, and Sony have the advantage of what is called "pass-through-TTL" radio systems. The transmitter is mounted in the hot-shoe, then the flash is mounted on top of that, but still retains TTL for that flash. The transmitter then also triggers any flash or strobe with a reciever connected to it. No one makes one of these for Leica.
The absolute ideal set up would be a SF58 in the M240 hot-shoe and a Profoto AIR transmitter on a bracket to fire a Profoto B1 … however, you will not be able to utilize the TTL function of the B1, which currently only Canon users can do, and supposedly Nikon users eventually will also (for your Nikons).
Leica has always been technologically behind in flash utilization.
