Product Description:

YongNuo have released the long awaited updated RF-603 II manual flash triggers. The RF-603 II are the follow up to the original and very popular inexpensive RF-603 flash triggers. And the MK II finally rectify many of the basic shortcomings of the original RF603 and RF-602 triggers.

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)
•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)

Sync Speed -
Low sync speed was always one of the main shortcomings of the RF-602, and even worse with the RF-603. Now that this is improved with the RF-603 II, it simply means you should be able to get a clean frame without any shutter (or black band) showing in the frame at your cameras maximum sync speed (1/250th etc). Though the Canon 5D series sometimes have to drop to 1/160th even with an instant sync cord. YongNuo are stating this as 1/320th maximum

Locking Rings - 
The original RF-603 has no locking rings on the foot. This was a major oversight now that a flash could be mounted on top of the transmitter on the camera. They would both simply fall off the camera hotshoe! The RF-603 II now has locking ring and locking pin.

The RF-603 II is still manual pass through hotshoe only though (the extra contacts seen on the hotshoe are only for the flash wake up feature).

Power and TX / TRX Switch -
Firstly the power switch has finally been moved to the side of the case, so that you don’t have to remove the flash from the trigger to switch it on and off like the RF-602 and 603 require. This alone would enough reason for many people to want to update.

More significant functionally though is the new TX – TRX option switch. The RF-603 are transceivers, meaning they are the same unit for transmitter and receiver, and can switch automatically between transmitting and receiving mode. This ability caused a number of extra issues in the original RF-603 though, like not being able to fire on non Canon/Nikon cameras, or fire the test fire button off the camera hotshoe.

So to help resolve these issues YongNuo have added a switch to the new FR-603 II allowing you to set them as either TX or TRX. TX being set to transmitter mode only, and TRX as self switching. TX mode is used when the transmitter is held in hand for taking light meter readings with the test fire button, or when used as transmitter only on the camera. If using combined flash and shutter release TRX mode would be used. Receivers would always need to be set to TRX.

Shutter Release -
One of the big advantages of the RF-603 (due to transceiver design) has always been the combined camera shutter release ability. You can fire the camera with an RF-603 used as a wireless remote shutter release, as well as fire remote flashes at the same time, with just the one radio trigger attached to the camera. Where as most non transceivers require 2 separate triggers  attached to the camera to do this. So the RF-603 offer a neater solution connected to the camera, and one trigger unit less cost.

This is where the TRX mode would also be used with the RF-603 II attached to the camera (via both the hotshoe, and a cord to a the cameras shutter release).

This also means you have backup transmitter, receiver, and shutter release units, as they are all the same unit and interchangeable.

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.

Versions -
The RF-603 II come in separate Canon and Nikon versions, though this is mainly for the flash wake up feature. Apart from that flash wake up the Canon and Nikon version can work together. There are Canon C1 and C3, as well as Nikon N1 and N3 versions available. The difference between the Canon C1 and C3 is just the shutter release cord compatible with different Canon cameras. That is the same with the Nikon N1 and N3 etc versions. The RF-603 II are also backward compatible with the original RF-603 (but not the RF-602).
