Why are fast wide lenses so expensive vs fast long lenses? I don't understand it...an 85mm f/1.8 has to capture more light on a reduced angle (hence the large front aperture) but a 24mm for example has a wider viewing angle to capture more light! Why doesn't Canon for example have cheap wider angle glass? I just dropped $290 for a brand new Canon EF 35mm f/2 but why is the 35mm 1.4 more expensive that some of the longer lenses just as fast?! Doesn't make sense to me...its also a pain trying to get wide shots on a crop sensor body...I mean yeah I can get wide shots but not wide shots at f/2!
