Sony A55 / A33 DSLR Problems: Camera Sensor Overheating

A recent video that accompanied Sony’s launch of their new DSLR’s the A55 and A33 was set in a snowy scene. This could have been to keep the new cameras cool as there seems to be a problem with some of the new technology found on them.

Vlad Savov of Engadget is reporting that when using the cameras to shoot video for any longer than eleven minutes with the Image Stabilization on, and in temperatures of 20 degrees Celsius or more they overheat. On the A55 this happens even sooner after only nine minutes.

If the Image Stabilization is switched off the DSLR’s manage the maximum of almost thirty minutes of video footage. Sony has blamed this problem on the APS-C sized sensor found on the cameras. The problem is not limited to only Sony though, as Engadets own Nikon D5000 won’t last more than five minutes no matter what they try. This problem is not good if you buying them to regularly shoot video.

hi the alfa 33 in turkey now and in the summer the temp goes up too (40°c or more …i can still tack a vidio clip in the sun 4 around 11 minutes with stabilizator on (no problem )


Hi, the Alfa 33, in Chile at this time of the year (30°c or more), still can take up to 10 minutes of video with image stabilizator on. (without any problem with an old Memory Stick Mark1).


the problem is that it make video unusable in place like here (australia) where it is often over 30c (not 20c) and reasonably often over 40c. How much video would you be allowed to do, 10 seconds??


this is from the manual:

Camera overheating. Allow it to
• The camera has become hot
because you have been shooting
Turn the power off. Cool the
camera and wait until the camera
is ready to shoot again.

this no only happens with video, taken pictures for along period of time too.-

regards! sorry for my english

Big whoop for a small detail. This is a DSLR(-like) camera perfect for short clips, not a video camera.


Since they can't find any fault with the Sony a 55 and a33 they seem to have come up with this "heating" problem. By the way, who's gonna shoot movies for so long with a still camera??
Whatever u guys point out, I am going to prefer Sony a 55 over Nikon 3100 d and Canon 550 that I had chosen for options.


Not good? All DSLR overheat for video. Canon 7 and 5DMarkII has 12-minute limit per video. Nikon D90 has 5-minute limit. How is this even a news? No one shoots long clips. They shoot several shoot clips which are also easily edited and combined later in movie editor.
