All you need to know about lenses, | ||||||||||||||||||||||||||||||
Dummy lenses - Dummy cameras need dummy lenses, but you don't need to be a dummy to figure out the most appropriate lens. Barrel lenses - A whole range of miniature lenses intended for use exclusively with Printed Circuit Board (PCB) cameras. Fixed Manual Iris lenses - Most installers wont touch them with a barge pole, yet manual lenses are our singular most important optics. Fixed Auto Iris lenses - Both Video and Galvo type automatic iris lenses are almost the industry standards .... how could this be?. Varifocal lenses - Extremely popular amongst installers, but are they the best option for end users? Manual Zoom lenses - Rarely used but extremely useful; what are the advantages over powerful varifocals? Motorised Zoom lenses - Serious glass with attitude - if you need to spot moths at one hundred paces ..... Pinhole lenses - The black art of covert surveillance - and its pinhole lenses that make it all happen. Photographic lenses - Put a nice chunky telephoto lens on a surveillance camera .... then pick yourself up off the floor!! Macro lenses - Extension Tubes, Reversing Rings and Close Up adaptors, lenses that bring you closer to your subject. Specialist lenses - Aspheric, Catadioptric, IR corrected, Germanium and a whole lot more. & Lens Accessories - Range extenders + adaptors + fun with filters (if you like that sort of thing!). | ||||||||||||||||||||||||||||||
