hi everyone.
i have canon 6d and some nice lenses: 17-40L, 35L, 50L, 100macro, 200L
i am in photography business for a long period (10 years)....and start video recently. Now when i learn a lot about video recording and processing i thinking about to start to do stock video seriously.
so, my question is about camera. Is it better to upgrade to 5dIV and use all lenses i have, or to buy panasonic gh5. What is better camera for stock footage business.
