Hey guys.

Thought I'd get the old tamron out again and have a go. This pic was taken on tripod with the self timer activated to avoid camera shake.

EXIF details as follows:

300mm
f 10.0 1/125 sec
ISO 200

The lens seems sharper when not zoomed out far, but at 300mm I get this (This is a crop of the image and the focus was on the horses)



Should I return the lens?

Based on your shooting details that shot looks very very ordinary. I don't have the lens but I can't imagine it is that bad under those conditions and stopped down. I would say return it, but hopefully someone who has one can confirm

Hi Owen,
I have the Tamron 28-300 lens. While I know it is quite soft I certainly don't get the problems that you are having. Here is an example.



100% crop
1/800

Return it, but try to deal direct with the distributor rather than the local supplier.

Nothing more useless than snap-tackle that doesn't work!!
