gizmo: CLS, not sure, i think so, at first i thought was optically, but after sometime i use it, it requires a signal (data) to know what it needs to fire to trigger. no idea.
sony, optically, but the optical has a pulses that only alpha flash understand.
i used to think those general optically can be trigger by any flash was good flash, used to hate sony for only able to trigger by sony, but after few public strobist, i think it very useful now, noone can kacau ur flash.
there is one time i used SB900 trigger by my alpha (lack of flash that time) and adjust the SU4, and small flashes (even car drive pass, reflection from the sun, the car is at the road which is at least 10meter awayyyy) triggers the flash =.=
Added on June 23, 2010, 12:58 pmthe 105 is just snooting it further, still researching, the snoot (DIY), can further increase distance or not, theoretically, it should not.
the 105 is just making the flash more concentrate in one area, but even 105, i ever shoot something 150-200 meter away, full power, iso3200, F5.6, no problem.
