Visa And A Fellow Kalahari Blogger

My visa has finally arrived! I’m now all set with everything I need, all I have to do is pack and get on the plane!

I will be posting a photo packing list in the next couple of days.

Also I found Adam’s blog. He will be arriving the same time as me and is also interested in photography so if you want a different take on things check it out and follow him as well!

Welcome to Adam’s Kalahari Blog..

Sigma 120-300mm f/2.8 APO EX DG OS HSM Review

I will try to keep this review fairly brief as there are several more reviews and much discussion about this lens elsewhere (see this discussion: http://photography-on-the.net/forum/showthread.php?t=934592). I have put the good/bad points and a conclusion at the top for easy access.

 

UPDATE:  My review of sigmas newest version of the 120-300mm, the OS “Sport”.

 

Some pictures of the lens with my 7d attached (yes it was raining!):

Good points:

  • Zoom

Bad points:

  • Reliability (a massive negative for some users, not so much for others)
  • AF maybe not as great as it could be (although it’s still good)

Conclusions
