Sony A55, A33: Over-Heating Image Sensor Limits Video Recording

Engadget:

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.

Bonkers.
