Excuse me, what kind of canon machine to buy, shoot feature films, commercials, promotional films, wedding photography!
If it is more than 2W, go to Rabbit 5D3, that is, the high sensitivity and focusing system should be strengthened. The price is not suitable for you now, and there is light leakage. You can go to the next ML plug-in to study the lens that plays a great role in focusing, especially in video shooting. If it's a lens, you can handle more than 90% of the situation, and then you can save money by installing similar shelves and flashlights, which is similar to your budget.
