Tamron AF016P-700 SP AF17-50mm F/2.8 Di II LD Aspherical (IF) Lens with Hood for Pentax AF Cameras (Black) (Model A16P)

welcome back to another lens review I thought I'd have a look at the Tamron 17 250 millimeter F 2.8 very popular lens and this particular one has been out for quite some time originally was released way back in 2006 and it's still in production I put the lens specifications on the screen for you so you can refer to that you don't have to go anywhere else to find that information this is an aps-c lens for a 1.5 or 1.6 times crop bodies and it's available in the four minus LR mounts to start with I will give you an overview of the lens just to show it to you in a bit more detail so you can see it the Tamron is I fill in foldable lens but the build quality is a slight step up over a kit lens we do have a few features worth talking about there are curved aperture blades which can sometimes help with the out-of-focus areas couple of shots there to show you open and closed aperture with these
