A rather perplexing decision by ALL the dSLR camera manufacturers (Canon, Nikon, Olympus, etc) who have implemented remote TTL metering flash capability<\/a> is to use infrared technology instead of radio waves.<\/p>\n

Whilst infrared works reasonably well for many situations, it has major limitations placed by line of sight and limited distance from camera. In particular, placing flash strobes inside umbrella softboxes or behind the camera can mean your IR triggering no longer works and you have to resort to optical or manual radio wireless triggering devices (eg. CyberCommander<\/a>, Pocket Wizards or cheap Chinese Ebay versions) and thus manual flash exposure (although I usually prefer this anyway).<\/p>\n

Canon and Nikon users have at least one 3rd party option (RadioPoppers) using transmitters and receivers which convert the IR signals to radio wave signals to remove the constraints of IR, but at a price and the nuisance factor of ensuring the receivers are actually placed to detect the IR signal.<\/p>\n

RadioPopper<\/a> have just announced their 2nd generation product “X system” which should be a significant improvement and the key features of the PX models are:<\/p>\n
