Hähnel Giga T Pro II £80, $95
More compact than the Phottix Aion, this wireless remote features an almost identical set of shooting options, from straightforward single, continuous, timed bulb and self-timer modes to more complex variable delay and programmable time-lapse shooting. It lacks the Aion’s bracketing option for long-exposure sequences, but adds a secondary interval option. This enables you to take sequences of shots, for example a few seconds apart, within a longer time-lapse period.
The claimed 100-metre maximum range is more generous than in the Phottix Aion but, in our tests, both controllers managed to cover similar distances in practice. Overall, there’s little to choose between the two controllers, but getting to grips with the Giga T Pro II is slightly less intuitive.
