Hahnel Giga T Pro II - £60/$100
Like the other two Hahnel remotes on test, this one is available for Canon, Nikon, Olympus and Sony bodies. Along with a 100m wireless RF range, there's a full feast of features including adjustable self-timer delay, single, continuous and bulb modes, and interval settings for time-lapse shooting.
Better still, there are two independent interval options, so you can shoot a programmed burst of exposures at set intervals throughout a longer overall period. Everything's controlled via a neat interface based around a four-way pad and LCD display. Build quality is excellent, and overall the Giga T Pro II puts the Canon TC-80N3 to shame, while costing only half the price.
Phottix Aion - £80/$90
A significant step up from the TR-90, the Phottix Aion boasts wireless connectivity with a range of 60m, and comes with cables to fit both types of camera connection. The transmitter unit is packed with all the features you need for selecting different drive modes, programmable self-timer delays, adjustable long exposure (bulb) shooting and time-lapse photography.
There's even an adjustable exposure bracketing option for long exposures, and everything's wrapped up behind a neat control panel with LCD display. You can also use the controller in wired rather than wireless mode, connecting the transmitter direct to the camera using one of the supplied cables. It works with Canon, Nikon, Sony and Olympus DSLRs.
Canon TC-80N3 - £120/$136
Despite being a wired rather than wireless controller, the TC-80N3 still requires a single CR2032 battery to power its LCD display and all-round cleverness. Connecting to compatible cameras such as the Canon EOS 5D and Canon EOS 7D via a three-pin plug, the unit's features include a self-timer, long-exposure timer, interval timer and the option to set the number of shots in a sequence.
It also works as a straightforward remote control, with the same basic functions as the RS-80N3, even with no battery fitted. It's simple to use, with a switch that cycles between the four main operating modes, a start/stop button, LCD display illumination switch and jog control for altering the settings.
Canon LC-5 - £335/$430
In addition to being a consummately professional piece of kit the LC-5 is real beast of a controller, with the receiver module and transmitter taking eight AA batteries between them. The unit is compatible with three-pin terminals on DSLRs such as the Canon EOS 5D and Canon EOS 7D, and there are three infrared channels to reduce the risk of your camera being fired by someone else's controller.
You can switch the camera to continuous drive mode and then select between single or continuous drive, or a 3.5-second delay, on the controller from up to 100m away. It works for bulb shooting but the two-stage shutter button has no lock, so you have to keep the button pressed for the whole exposure.
