A:AnswerYou are able to connect the ILCE6600 to a USB power source and record at the same time, keep in mind that using a USB power source will only help extend the amount of time you can record since it only provides a trickle charge. The maximum continuous recording time for a single movie shooting session is approximately 13 hours. While recording the unit will not turn off unless there is no power available.
A:AnswerSony's commitment to customer satisfaction is our top priority. Comparing both those lens, you have a prime lens and a zoom lens. However, the 50mm has wider aperture at minimum focal length. f/1.8 vs 4.5f. Both are great lens, just depends on your needs. The 210mm is a telephoto lens compared to the 50mm. Thank you.

A:AnswerIt has fantastic motion tracking so it's an excellent choice for sports photography. High iso shots are very usable so one can use fairly high shutter speeds even when indoors.
A:AnswerHi Roman, all the Sony full frame lenses designed for full frame sensor cameras can be used with the Sony Alpha a6600. Please be aware that the focal length will be multiply by 1.5x. For example: a 50mm FE lens will become 75mm lens on a crop sensor camera body. Please also make sure that the full frame lens you are looking to use with the camera is an E-mount lens.
