I created this field table for myself to tuck into my camera bag. I thought it might be of interest to some of you landscape photographers too, who are using a sigma 10-20mm and Nikon d90,80,70,70s,60,50,40,40x. your welcome to print it out. just visit my photos page. All measurements are in metres not feet sorry if your not good with metres. I got the information from the link below.
