Lens for A33

Ahoy!

The Sigma AF 100-300mm F4 EX DG (IF) APO is all you really need (bar a 300mm/2.8 prime).  For static subject, a dedicated Sigma 1.4x EX DG teleconverter will help if AF speed isn't a factor as the TC tends to slow down the AF speed.

I have 2x copies of the lens and I have one for sale.  It's wickedly good at all apertures and focal lengths.  Samples available via URL below. I managed a Kestrel 'snap-shot' hovering above me which was pure luck.  You'll see the lens used in the right column, but you'll have to scroll a few pages.  I have other aviation images on other sites such as JetPhoto's.net.  Images were taken with A700.
