Photography can be about a lot of things and when it comes to carrying gear it can be about compromises.\u00a0 How much space do I have for lenses and how much weight am I willing to carry?\u00a0\u00a0When it comes to the wide angle end of things you can’t really beat having a really nice\u00a0lens that captures an expansive view.\u00a0 Often though for reasons of weight it can be easier to just carry a lighter kit lens that maybe goes down to 18mm on APS-c or \u00a0maybe a better lens that goes to 16mm but if your willing to carry the extra weight of\u00a0an additional\u00a0lens there is something special about going all the way to 12mm on APS-c.\u00a0 This would be equivalent to 18mm on a ‘full frame’ camera.\u00a0 The horizontal angle of view of a 12mm lens on APS-c equates to 88.5 degrees<\/em>\u00a0\u00a0<\/em>while an 18mm lens is 66 degrees <\/em>this is a signifigant difference illustrated\u00a0bellow.\u00a0 (Note I am referring to horizontal angle not diagonal, human vision\u00a0with two eyes is\u00a0nearly 180 degrees horizontally but\u00a0a good portion of that is peripheral) <\/em>

Done well a wide angle image helps to make the viewer\u00a0feel more like they are right there looking at the scene for themselves. You can back up of course to take in more of the scene but that isn’t always an option as in the illustration image taken from a logging road\u00a0bridge deck.\u00a0 Another option is to stitch together several images but that can have issues and isn’t suited to anything with motion.\u00a0 So sometimes there really is no substitute for a good wide-angle lens.\u00a0 Personally as I shoot with a Pentax APS-c DSLR I use the smc PENTAX-DA 12-24mmF4ED AL[IF] but there are\u00a0 different options for it and other camera systems.\u00a0 Additionally these images are combed from 4 different cameras (Pentax K10D,K7,K-01,K3) proving my assertion that spending money on a lens is a better long term investment than on a camera.<\/p>\n

Here are sample images with this lens all\u00a0taken at the widest setting of 12mm<\/p>\n\n\t\t
