Oh, my favorite subject! Lighting.
If Canon or Nikon could pull this off it would be amazing. It is a key feature of my MFD systems that I can't live without. It would make a higher meg 35mm DSLR more attractive. Problem is that I'd need all the 35mm lens system to do this ... meaning an all new dual shutter camera, and all new FP/CS lenses ... which is unlikely IMO.
It is more likely that in future we may see the elimination of the shutter altogether which may allow faster flash sync speeds with FP lenses. When, is the big question.
Leica has
finally completed their proprietary Leaf shutter project for the S2, but it was worth the wait as the original spec jumped from 1/500 sync to 1/1000. :thumbs: Previous indications were that the S2 had to get the focal plane shutter out of the way also, so in theory it should be possible for a 35mm DSLR. I do not know if that is true now that they got to 1/1000 sync.
An adapter would only work if the camera originally was designed as a dual shutter ... like the S2, which is what allowed the adaption of the H Leaf Shutter lenses.
Presuming that you'd want portable power, you can get to 1/1000 flash duration with the Profoto 600B AIR @ full output, and the Profoto AIR remote does sync speeds up to 1/1500 in fast mode. Problem is, 600w/s usually isn't near enough to kill bright ambient while shooting at f/2.2 let alone f/1.4 or f/1.2 without some heavy duty NDs, and you are still relegated to 1/200 or 1/250th remote speeds with FP cameras ... plus, the B600 has a 2 second recycle @ full power ... and the levels cannot be controlled from the camera.
That can be mitigated by using two 600Bs @ half power running one Acute dual tube head. Faster recycle, and shorter flash duration for action shots ... but still limited to 600 w/s, no levels control, and 1/250 remote FP speeds.
In contrast, the Hensel Porty 1200L puts out 1200w/s, recycles in just under 1 second @ full output, full flash duration is around 1/1200 with the Hensel Porty Speed head ... and it has three remote receivers built in ... including Profoto AIR ... and it does 450 full power pops on a single charge compared to 200 with the Profoto.
BTW, I do have both horses in the race as well as the EL Quatra. However, I do use the 600B at weddings a lot. I gave up on Speed-lights some time ago ... huge waste of time and money trying to make it work (it'd take 6 SB900s arrayed in a single softbox to come close to the 600B alone ... and a dump-truck full of speed-lights to get near the Hensel output, if you could even fit them all in a modifier :ROTFL
I use a speed-light for fill only.
Frankly, I cannot wait to get the LS lenses working on the S2 and get out from under the 1/125 sync speed ... the shot below was done in early evening and the background was being blasted by dappled light with the subject in shade ... so I exposed for the background and lit the subject with the 600B @ full power using a Profoto Octa/Gold camera left ... the TTL Leica SF58 on camera with a Graslon Prodigy diffuser @ +2 stops comp for fill (S2 rotated right in portrait orientation to place the flash on the right side opposite the Key light). The 22" print is gorgeous.
If the scene had been shot earlier with more sun hitting the background, I would have been screwed.
I love lighting stuff. So many possibilities :thumbup:
