The camera can be rebuilt but I would rather buy a camera used for video knowing the mechanical moving parts of the camera are still pristine. For a still photographer on this camra the more actuations of the mirror moving out of the way of the sensor will wear those moving parts at the points of contact. For the 7D mark ii there are no moving parts when recoding video so video recording hours do not adversely affect the useful life span of the camera. When you have mechanical moving parts hours or shutter counts do matter because the moving parts will wear down almost like clock work. Back in the film days mechanical shutters where used.

I read 'when it comes to video only hours matter' Somewhat true. Let the oldtimer fill you in, sometimes we are good for something:) I would rather have a used DSLR with 50% of its expected shutter life used than one that had been used for hundreds of hours of video discussion about 'does shutter count matter'.

I use a Canon XF-400 camcorder for sports video and leave its fan set in the default mode of continuous rather than temperature triggered operation which comes at the cost of slightly reduced battery life but keeps the electronics running at a temperature far more conducive to a long life. Purpose built better video cameras and camcorders use forced air cooling to manage this heat buildup giving up some of the weather resistance of most DSLR bodies to provide sustained video capability without cooking the internals. A DSLR that has been used a lot for video will have a greatly increased rate of internal component aging.

That increased battery draw is converted into internal heat that has to be managed.Ĭanon's 1DX series are the best of their DSLR bodies at video heat management with their heat pipe design but even these bodies will get very hot in higher ambient conditions shooting sustained video clips. Reviewers tend to attribute the electronic viewing screen in mirrorless setups as the reason for reduced battery life but the bigger current drain is from constantly reading the sensor and doing A to D conversion along with powering the supporting cast needed to provide the data capture, conversion, and processing functions. Mirrorless is a hybrid between the two designs and has some of the same thermal management concerns as shooting video (and shares some of the same hazards due to a sensor constantly exposed to sunlight/laser damage when in operation). As to video hours, heat management is an issue shooting video with a DSLR because video generates far more internal heat buildup than still photography with the sensor, A to D converter, and associated processors running effectively at a continuous duty cycle while shooting video instead of the low duty cycle imposed by photography.
