Bought 2 of these, super satisfied, very sharp and versatile zoom range.
Bought this lens for a new Axis M 1125 camera. My goal was to focus tight on a single object, 40 feet away, so depth of field was not an issue. The clarity of the image is excellent for a lens in this price range. If I had the option, a higher end camera with remote zoom and auto focus would be sweet...but for this budget priced combo, I'm delighted. Shout out to the BHP rep who guided me to put this order together. I explained my requirements & he took hs time to make sure all items of the total system were compatible. I'll order more CCTV cams here in future.
