Originally posted by normhead I like my Sigma 70 but it's heavy, but it is a great performer. If you want a macro you can also use for portraits, this might be the best. A great lens for studio work, but too big and heavy to add to 4 other lenses in a camera bag if you're hiking.
I use a Lowe-Pro 100 sling when hiking. For serious walks it contains: K-3 with grip, 12-24 or *16-50, DA 55-300, FA 100/2.8 macro, AFA 1.7x. I also carry 2 L water in a canvas holder that can be dunked to keep the water cool, and lots of C******te for energy in my pockets. Light duty is 12-24 and 55-300. Same water bottle. If SWMBO is along the chocolate is replaced with something more "healthy".
