I use this camera in a video studio to replace a Logitech Brio. The camera is manual, with separate adjustments for Iris, zoom, and Focus.The adjustments are fine and sensitive, it takes some time to get used to them, but the focus is perfect when done.The camera does need a lot of light if the depth of field is to be reasonably deep. This depends on the type of filming required. I need around two feet (600mm) of depth of field. I got this as a trial, and at first, I was disappointed as it takes a lot of fine adjustment for a decent picture. Now I am pleased, but the adjustments took a long time to be accurate enough to accept.I will soon order two more to replace webcams that only do digital zoom.It does work with Manycam software. I noticed some other models of this camera specifically say they are not suitable for multi-camera software. This model is, although I have not used it with multiple of these cameras. When I get my other two, I will update this review.I love everything being manual. Many may not. Adjust one adjustment, and the others need readjustment. It does take time for that perfect picture, but it is worth it.It takes me back to pre digital film cameras.
