Heat Problems for Sony NEX-5N in the video recording?

These days he is doing really talked about a video posted on YouTube that highlights a problem related to the new mirror less Sony NEX-5N , credited with 16.1 mega pixels and is particularly aimed at those looking for a camera with advanced video capabilities. Although the upper limit on the movie recording is equal to 29 minutes, for reasons of customs and trade name (otherwise the machine should fall into the category of video cameras), the video shows how the car is turned off as a measure to prevent overheating after about 23 minutes of recording.




The test was done indoors with a temperature of about 30 ° C and a slow stream of air, recording a full HD 1080p video at 60fps (the newly introduced with the new AVCHD format Progressive 2.0), leaving the display swivel slightly away from the body. The machine was displayed on the display the icon of the principle of overheating after about 12 minutes, then powering off automatically at 23 minutes and 22 seconds.

At first glance it might seem an important issue, but an interesting piece published by Photography Bay helps to draw conclusions more considered. First, it is recognized that a given digital sensors should be met by using heat: this was the first reason that has kept away for a long time, and the Live View video from the cameras with larger sensors.

This is true not only during movie recording: also a session of intense volleys and close-ups can lead to overheating of the cameras; the source cites several instances where this has happened to his Canon SLR. Secondly, other cameras, as a matter of file size, have much lower limits to video, such as 12 minutes. In third place is not a common situation to record HD video at 60fps for a long period of time, often the clips are much smaller in terms of time. Moreover, as can be seen from the video, the biggest problem in this area of application is the battery life of videos in one of the things that strikes you most is the speed with which the indicator falls in the percentage of remaining charge.

To summarize the issue definitely exists, but has practical implications in a number of cases that we believe content: probably also with the increase of interest in the capabilities of video cameras by the public is likely that producers are already working to limit this type of defect.
