Shooting images in the darkness of the cave environment can be challenging for even the most sensitive of camera autofocus systems which is where a decent focus (spotter) light comes in.
Recently I’ve been testing the Bigblue Al-250 AFO spotter light from Liquid Sports. Constructed of solid aluminium and rated to 100m, the Al-250 feels light a quality item – it’s reassuringly heavy and the ‘twist on/off’ mechanism is very smooth. It’s supplied with a YS mount so can be used with most camera systems with the appropriate mount adaptor.
What really impressed me about the Al-250 is the quality of the light that it produces which is bright, even and nicely diffused from its 250 lumen CRE LED head. The light features a sensor which switches the focus light off when your strobes fire.
Like all focus lights with this feature, this function works best when shooting macro in TTL mode as the strobes will produce a pre-flash. It does work in manual mode too but the lack of pre-flashes may cause the illumination from the focus light to appear in your shot under very rare circumstances. As it uses an LED head, the soft light and cool colour temperature of the Al-250 is close enough to modern strobes not to produce any discolouration.
My only feedback on the Al-250 relates to the YS mount that is supplied with it. Whilst the light itself is of very solid construction, the YS mount isn’t quite up to the same standard. Personally I would have liked to have seen this made of aluminium too – as it is, you have to hold onto the torch with both hands to turn it on and off.
In conclusion, the Bigblue Al-250 is a quality item that I’d be more than happy to recommend to any underwater photographer. It’s solid, works well and produces a very pleasing, soft light that made focusing in the low-light conditions inside the caves of Mexico an absolute doddle. It’ll certainly be staying on my camera housing!
