The link to the review doesn't seem to be working, it could be a traffic issue. I'll leave the links up and we'll see if it corrects itself.
Frank Wong has completed his review of the soon-to-be-released Tamron 150-600 f/5-6.3 VC zoom lens. This is currently the longest zoom lens currently in production and looks to be a steal at only $1069. If you're a birder or wildlife photographer on a budget, this lens may be the perfect addition to your kit.
The review has been translated to english and shows a lot of sample images.
“A good value lens appear in the market ! 600mm reach , F6.3 does not a matter for DSLR nowdays which have good ISO , fast focus , light weight (1.9KG with tripod mount), also a very long warranty period (3-6 years as i remember in Hong Kong ) . I am very impressive with this lens .”
