The Sigma 300 to 800mm f5.6 Zoom
Winning The Hearts And Lens Mounts Of Dedicated Wildlife Photographers
As soon as I opened the box
I was in hyper-drive. There before me was one very impressive piece
of optical gear. Made by Sigma, this new telephoto lens includes useful
focal lengths from the ever-popular 300mm to a mind-boggling 800mm.
For photographers on the go this just could be the ultimate "one
lens" package especially with the new restrictions on both the
airlines and world travel today.
No Small Lens
But wait, it gets better. When
out in the field I took both my F5 and D1X cameras. On the F5, the 300-800mm
with the Sigma 1.4x extender is now a 420-1120mm f/8 lens. Factor in a
digital camera and you wind up with a stock 450-1200mm lens, with the
optional extender you now have a 630-1680mm lens.
The other neat thing is the
way the Sigma lens hood was designed. On all of my other super telephotos,
trying to either install or remove the hood can be a frustrating experience
simply because of the narrow front mounting ring and somewhat awkward
thumbscrew. On the Sigma, they've machined in a bayonet type of
mounting which is a big improvement in not only convenience but in speed
and security. The hood is reversible for travel, has a thumbscrew to snug
everything up, matches the finish of the host lens, is flocked inside
to minimize reflections, and comes with a full leather hood cover.
