Latest Review Posted	Sigma APO EX IF Macro 180mm F3.5 When using it as a telephoto lens the AF is extremely fast. When using it as a macro lens I focus manually and it's very easy with this lens. 180mm equals to 270mm on my dslr so it's really great using this lens when you taking macros at butterflies or other shy insects. I have the bad habit of buying and selling most of my lenses because I like to try new ones. But no chance that I'll ever sell this one as I searched for this lens on eBay for a very long time, it's not often for sale (with K-mount). Sigma 180mm Macro gives you the best value for your money in the Macro Lens category. This is a full format lens so if Pentax ever will make a FF dslr I'll be ready :p
