Cool, really can't wait to start having fun nowit might be just about right at that distance you will have to have a play around with it as i don't have a desk with that much space.
It is the same model yes! You won't regret the purchase im confident of that!
No worries at all i have already boxed it up and also thrown in something called an ND filter for you to try ( you screw it to the front of the lens and it gives you one more method of controlling how much light comes into the image ) these are really nice when you are outside because it means you can use a lower F stop such as F1.8 without having the image over exposed. They can be had for nice and cheap mind you
im not sure how well the camera works as a webcam however there are two ports on the side of it, one is a usb and one is a hdmi output so i would imagine you will need to get a hdmi cable to get full function from it as i think the image over usb will be really limited due to the bandwidth of usb.
I'll be using it with the Elgato Camlink (buying from OCUK) even though it's not mentioned as compatible on their website I've read a few posts/comments that confirm it works perfectly.
