Dear Board,
New guy here, both as a poster and pretty much as a photographer.
I have read few online reviews of this lens but I was wondering if there are any members here who have firsthand experience with the Tamron 200-500?
I will be using the lens on a 20D with a monopod or tripod for nature photography. I am also considering the Sigma 150-500 OS and the Canon 100-400L IS USM. I know that those are not necessarily lenses that can be directly compared since the latter two have image stabilization and the Tamron does not.
Budget is a consideration with a limit of $1000.00 +/- a few $'s. I could get the Sigma in my price range but I know I'd be looking at a used 100-400L. I am attracted to the Tamron primarily because it is lighter in weight and it comes new with a 6 year warranty.
Anyone have any advice to offer?
Thank you,
Tim Murphy
