spotted that the video mode of Sony's new A55 and A33 digital SLR cameras shuts down automatically once the sensor starts overheating. Depending on the ambient temperature and whether Image Stabilization is turned on, video recording can be limited to barely 6 or 7 minutes.
It turns out that these oh-so-revolutionary translucent mirror shooters can't keep their cool for any longer than 11 minutes when recording video at a temperature of 20 degrees Celsius with Image Stabilization turned on. The A55 is even quicker to overheat at 9 minutes, though it's worth noting that with IS switched off you can obtain the maximum of nearly half an hour of footage -- provided the weather doesn't heat up. Sony blames this on the APS-C-sized sensor within, and it' true that plenty of DSLRs come with artificial time limits -- our D5000 won't let us get past five minutes however we try to sweet-talk it -- but it's an irksome limitation to consider if you're thinking of buying either of these Alphas for their otherwise awesome video capabilities.
