I’ve just tested the Elinchrom EL-Skyport flash triggers with the Sony RX1. I have both good news and bad news to report:
Good News: Sony’s 2012 cameras including the RX1 now use the ISO standard hotshoe, which should mean that the world of flash accessories should just work as they should. I’m sure that the move to abandon existing Sony system users wasn’t taken lightly but it will certainly be a positive for pros thinking about switching systems to Sony.
Bad News: The bad news however is that my version of the the Elinchrom Skyport transmitter does not work with the RX1 out of the box. In my testing, the Skyport wireless flash transmitter does not sit correctly in the hotshoe. I do not have the newer “SPEED” transmitter to test its compatibility.
Some theories: Perhaps the front of the skyport slopes forward or perhaps the limited depth of the “U” part of the RX1’s hotshoe is causing the poor fitting. The latter could be due to the design to accomodate the electronic viewfinder.
Temporarily, I was able to test the off-camera flash capabilities by using Nikon’s SC-17 coiled off-camera TTL flash cord. I was able to confirm that the hotshoe does properly trigger the transmitter and receiver.
- Last piece of Good News: The flash sync with an 300RX studio monolight is possible up to speeds of 1/1200th of a second. This is considerably faster than the 1/250 flash sync speed by traditional SLR’s and some mirrorless cameras, including the full-frame Nikons. This is due to the RX1’s leaf shutter.
(For reference, the specifications on the 300RX quotes a 1/2850 sec flash duration, although I suspect it doesn’t account for any delays in trigger transmission or warmup. Speeds faster than 1/1200 resulted in less amounts of light.)
