My following question is in regards to CCTV camera lenses. I am looking for a great Auto Iris Varifocal 3 to 12 MM lens that is manual focus. I have read some favorable comments on the quality of the Raymax brand. I am open to any brand and need input on specifications to look for. F-stop number varies from lens to lens and I don't know what is favorable. I also don't know what is preferable Video auto iris or DC auto iris. The lighting conditions vary from sunlight to dark. Any suggestions on what you have used or are partial to.
