24mm Mk II TS-E Problem

Thanks.

I did comparisons at a range of apertures and as you'd expect both lenses improve the more you stop down, however if anything the 17-40 moves closer to the TS-E.

I'd probably be happy with the TS-E as it was if it weren't for every review, especially the one on this site telling me how amazing the TS-E is wide open (which is what I'll be shooting at much of the time) and how it even edges out the dedicated 1.4 24mm L.

I've already returned the lens for another one.

That's what I'd expect. Even inexpensive lenses like the 50/1.8 and 18-55 kit lenses sharpen up a lot at f/8. Much of what you're paying for with more expensive lenses is sharpness at wide apertures. While the 17-40 is not cheap as lenses go, it's cheaper than most L lenses and it's wide open performance isn't stellar.

it's wide open performance isn't stellar.

Which is why I'm none too pleased with the TS-E which 'is' supposed to be excellent wide open yet I see little difference between my two examples.

Suppose I'll have to wait and see what the replacement TS-E is like.
