I don't have alot to compare it with but I had it in my office for a couple of weeks and I was pretty impressed with it overall. Optics seem great, with a really clear picture without noticeable aberration even zoomed way in. Also, low light performance seemed pretty good. My office lights are often dimmed right down and I don't recall seeing any noisy images.

The NDI Latency is very low, a few frames Max.

PTZ Control is pretty good, although again I dont have much to compare with but it seemed to behave pretty well, its not like a Porsche where you push the pedal and its already moving. it takes a fraction of a second to get started, but it doesn't feel 'laggy' and it doesn't really overshoot. With the right controller you can do quite precise control even when really really zoomed in.

You will find the specification somewhat similar to :

All in all, there was pretty much nothing I would say was noticeably wrong with it. A very nice camera.
