Hama RS60-E3 - £13 (around $20)
This is Hama's direct equivalent of the Canon RS60-E3 wired remote - it's pretty much the same size and it operates in exactly the same way. A two-stage switch enables autofocus and metering with a light press, and shutter release with a full press. The switch also slides forward once it's fully pressed, enabling you to lock it in place for bulb exposures or prolonged shooting in continuous drive mode.
The cable length is a bit more generous than on the Canon RS60-E3 equivalent, at 80cm rather than 60cm, but the two-stage button feels a little imprecise by comparison. Even so, it represents pretty good value.
Canon RC-6 - £15/$22
Bypassing the usual need for one of two types of terminal connectors, the infrared Canon RC-6 works with all current Canon cameras apart from the 1100D and variants of the 1D. Since Canon DSLRs only tend to have an IR receiver at the front of the camera, built into the hand grip, you can't operate the camera from behind.
But the RC-6 is particularly useful for self-portraits, with a range of five metres and a two-second self-timer delay, and unlike the older RC-5, the addition of a switch on the back panel also offers immediate shutter release. The main button is only a one-stage switch, so you can't activate autofocus and light metering in advance.
Canon RS-60E3 - £15/$22
Small and simple to use, Canon's RS-60E3 suits all cameras with a mini-jack remote control terminal, to which it connects via a 60cm cable. For tidy stowage, the cable wraps around the body of the controller and there's a dummy socket for the plug to fit into. The unit requires no batteries, and the only moving part is the remote shutter button assembly.
This has a good solid feel to it, with a precise two-stage mechanism for autofocus and metering with a light press, and shooting with a full press. Once fully pressed the button can slide forward to lock in place for bulb exposures or continuous shooting, without the need to keep the button manually pressed in.
Hahnel HRC280 - £15/$30
Ideal for photographers who have multiple cameras with both types of remote controller terminal, the Hahnel HRC280 fits both. The controller itself has a socket in which a cable can be fitted and locked in place, making it work with Canon, Pentax or Samsung DSLRs. Both types are supplied with 80cm cables, and you also get a two-metre extension cable; the controller therefore acts as a direct replacement for both the Canon RS-60E3 and RS-80N3 controllers.
The two-stage shutter button doesn't quite have the same level of precision as the Canon remotes, but it's still very good, and it also features a slide-forward locking mechanism for bulb exposures or continuous shooting.
Hama CA-1 - £20 (around $31)
A neat little unit, the CA-1 is a wireless RF remote for cameras that have a mini-jack remote controller terminal. It's cheap compared with most of the RF controllers on test, although it has a relatively limited maximum range of 30m, despite having an extending aerial built in to the transmitter (see the Hama CA-2 review for more).
As with other wireless remote controllers, you can switch between radio channels to avoid interference with other people's kit, using easily accessible switches on both units.
Hama CA-2 - £30 (around $47)
The Hama CA-2 controller looks and feels identical to the CA-1, but has an additional three-pin connector to suit cameras such as the Canon EOS 5D and Canon EOS 7D. Unlike most wireless remotes, the receiver unit doesn't have the facility to clip in to the camera's hot shoe, so it merely dangles from its connection terminal, putting a bit of a strain on the plug and socket.
The extendable aerial on the transmitter is a bit flimsy, but you can shoot from a few metres away, even through walls, without the need to extend it. As with the Hama CA-1, there's compatibility for single, continuous, self-timer and bulb shooting, but drive modes have to be selected on the camera itself.
