I have been playing around with my 12-24 tokina..and my experience so far is that 12mm has always been wide enough..whereas 24mm is not always long enough..but has allowed me to do some general shooting since 24 is 36mm perspective on digital..personally i believe a 12-24 range is more versatile..
any reviews on this lens yet? i thought it's been out for quite some time.. but seems like there's no comparison done yet on the ultra wides lenses yet? can't seem to find. if anyone can find, pls let me have the link!! thanks!
