Canon TS-E 24mm f/3.5L II
The Canon TS-E 24mm F3.5 L II is a lens which, given its price, has high expectations to meet. The good news is that, in almost all respects, it succeeds - the build quality is exemplary (certainly on a par with the EOS-1 series bodies it's likely to be paired with), and the new, more flexible system of movements works very well indeed. The ability to rotate the tilt axis freely with respect to shift increases the creative possibilities substantially, but despite this additional complexity the layout and operation of controls is still very straightforward and easy to master.
When centered, this is among the sharpest 24mm primes our there, with almost no CA or distortion. No matter what position it is in, this lens will draw straight architectural lines, with low color fringing even in the corners of the frame.
Corner sharpness isn't great in extreme shift positions, although this isn't a huge issue in normal use at small apertures.
