Die, für mich wichtigere, Neuerung wäre aber das Rädchen um das Teil auf der Kamera fest zu machen.
Ich habe oft noch einen Blitz auf dem Sender drauf ..und ohne wirkliche Fixierung werde ich aufpassen müssen.
Wohl war, ebenfalls große Verbesserung!
Gerade gegooglt und folgendes gefunden:
"Compatible with Non Canon / Nikon and Single Firing Pin Cameras
With the rise of alternate brand mirrorless cameras its becoming increasingly important for radio triggers to be as universal, and compatible, as possible with non Canon/Nikon and single firing pin cameras.
The original RF-603 would not fire at all unless attached to a Canon or Nikon camera with full TTL contacts on the hotshoe. The RF-603 II will now work on most cameras provided they have a standard (non Sony) style hotshoe.
The flash wake up feature will not work on non Canon/Nikon cameras though."
Hört sich doch gut an, ebenfalls noch eine Übersicht:
Improved Features
Higher Sync Speeds, up to 1/320th (RF-602 were slow, RF-603 were very slow)
Locking Rings on trigger foot (RF-603 and flash on top would fall off the camera)
Pass Through Hotshoe now usable (see point above) though still manual only no TTL
Power Switch Finally Moved to the Side (was blocked by the flash on 602 & 603)
Compatible with non Canon/Nikon and single firing pin cameras (RF-603 was not)
Tx will fire via PC sync cord the camera (RF-603 and later RF-602 would not)
Test Fire Button works off the camera hotshoe (for taking light meter readings) (RF-603 did not)
300v Safe Trigger Voltage (for hotshoe and PC sync port) (602/603 where low 12 volt safe limit)
Not Improved
PC sync port instead of a reliable 3.5mm mini-phone jack (why oh why… still after all this time?)
