Thanks for the input Huff..cannot see that link..it comes up with google error???Stuart,
I love my Tamron 28-75. I picked mine up at a local shop used for $300 USD and it has hardly left my camera since. It is very sharp and very fun to use.
For some reason, I can't get a photo to simply load in this page but the link below will open a picture I took in my backyard.
This was handheld, wide open then taken straight out of the camera with no PP.
Good luck with the decision
I have to agree with you about sigma,they have some cracking lenses in their line up now and I have owned a few of them..another one which I think is over looked is the 100-300mm f4,I sold my 70-200mm for this and tbh I prefer the images out of it as well..the 70-200mm was great but I reckon this is better.
Thought I had decided on the sigma yesterday and shop had one left but it was the display model and sorry but not paying top whack for a lens that has been sat on a shelf collecting dust and mauled by god knows how many people!
