Welcome to the
All you need to know about lenses,
And yet the correct choice of optics is perhaps the key to good images. If you plonk a top quality lens on a crappy camera, the picture will probably look ok, but if you try it the other way around, apart from at best having seriously horrible pictures, it will almost certainly be a complete waste of money.
So what are the secrets for selecting the most appropriate lenses?
Before we look at the "key three" , one very important point to consider is the lens mount.
Sounds nice and easy so far, but, and you just knew there had to be a but somewhere, the same threaded lenses are actually engineered as two different types; which are known in the industry as 'C' and 'CS' mount versions.
Both types of lens can be made to work on any CS mount camera, but the CS mount lenses will not work on C mount cameras. The explanation is actually quite simple (if you believe that, you'll believe anything!).
Decades ago when CCTV cameras were fitted with large format 'tubes', the lens mount (type C) was borrowed from the world of cinematography, that's film cameras to you and me.
