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.
