Soundy 1 Posted June 25, 2009 Anyone know of a manual-iris, fixed 2.8mm, C/CS-mount, 1/2" megapixel lens... that's better than f/1.4? Preferably f/1? Even f/1.2 would be an improvement... Share this post Link to post Share on other sites
Soundy 1 Posted June 28, 2009 Hey, thanks for checking... actually, I was mistaken, the cameras ARE 1/3" (IQEye IQ-511)... I found Pentax's PDF lens chart, it was very handy.... I just went from being at a loss to think of names of CCTV lens manufacturers (came up with Tamron as well), to being completely overwhelmed with them once I found a good combination of Google search terms Biggest problem is, 99% of the hits are for resellers who don't have complete product or spec listings.

Hi Soundy, 2.8 fixed NO . 2.8- vari focal yes Tamron do a 2.8-6mm, f/1.2 auto iris megapixel lens Fujinon do a 2.8-8mm, f/1.2 manual iris megpixel lens The Tamron is not IR Corrected, no sure on the Fujinon. both are good lenses. Spec shhets for both are available on line from the munufacturers web site I think. hope this helps Edited June 29, 2009 by Guest Share this post Link to post Share on other sites
Soundy 1 Posted June 29, 2009 Thanks, I'll give those a look! The IQs don't have iris drivers, so it'll have to be manual-iris lenses all around. Share this post Link to post Share on other sites
