[QUOTE="STM, post: 169722, member: 12827"] One criticism, and it is not the only one by far, that I have of the new lenses out these days, and it is not just Tokina of course but with most everyone of them, is a [I]lack of a depth of field scale [/I]on the lens barrel. With a lens of this short a focal length it is not that big a deal. But the way that lenses are made nowadays, you cannot set a manual hyperfocal distance to give you sharpness from a pre-set distance to infinity because you have no way of knowing at a glance what the depth of field is for any given aperture.
