Sigma APO EX 500mm F4.5 | | Latest Review Posted | Sigma APO EX 500mm F4.5
The previous review is not true: the lens works perfectly as it should (AF and metering). I'm not sure why anyone would think that the Sigma is manual only.
Now for my experiences: this is a serious hunk of glass and metal. Weighing in at more than 3 kilos, it's not easy to handhold. Optically, the lens is very very sharp. I have the non-DG verstion and it's said that the lens lacks a little in contrast, but that's not my impression. It mates well with the Kenko 1.5x converter.
All in all, a great lens if you need the reach for birding and wildlife shots. If you need one and find one: buy it! It's very hard to find one on the used market in Pentax mount.
