Camera Lens Hood

Camera Lens Hood
I'm having a little trouble with the Camera Lens reflex hood can anyone help me?

"I can use my hood with a filter? when I put my hood on my camera and I half click the shutter button for auto focus shifts with my hood I do not think the goal is to happen. Can anyone help?

Lenses that have the front element rotate as the focus (for example: Nikon or Canon 18-55mm), must be circular hoods designed for them. The generic "pedal" hoods, but they look neater, it will cause problems. As to your main question – if the front element rotates, then filters and hood also rotate. Some lenses are designed to do this, but in others it is perfectly normal. Yes, you can use your lenshood with a filter, but the recommended order is to place a UV filter or 1a first, then the hood. You can use a polarizer, but there are some filters really needed for modern Digital Cameras.
