View colissions

I want to reduce the number of draw calls by verifying if the view is colliding with "Some object" sprite. Eg. I have 50 enemies and i want to draw only who are colliding with the camera.and I don't know how.

Using sf::view getCenter and getSize, and if the view doesn't rotate, it's easy to compute an sf::FloatRect representing the view. (center ± size / 2, ...)
Then you can use intersects with the globalBounds of your sprites to check if they are colliding with the camera or not.
