Canon Today announced a new tilt/shift lens 17mm, the TS-E 17/4L, and an update to the current tilt/shift lens 24mm, the TS-E 24/3.5L II.
The new TS-E 17/4L is the widest tilt/shift lens yet offered. It has full 35mm frame coverage and when used on an APS-C crop conditions camera such as the EOS 50D professionals will provide the same angle of view as a 27mm TS-E would on a full frame camera. From the illustration it looks like the highly curved front element protrudes significantly in front of the lens barrel, so some care will be needed to avoid damaging it. A lens hood looks like an excellent idea with this lens.Obviously front caption filters won't be usable with the TS-E 17/4L. I'd assume it has a rear physical for filters, as the EF 15/2.8 fisheye does, but I haven ' t found any reference to a rear filter holder yet.
Both lenses allow independent rotation of the axis tilt and shift. Previously on the TS-E 24mm (and 45 and 90mm), the axes could be setup parallel or perpendicular, but they could not be easily adjusted in the field.
The current version of the Canon TS-E 24/$1150 4L sells for around, but the new version will be $2199 MkII and the TS-E 17/4L will list at $2499 when they start shipping in May.Street prices are normally the same as the "list price" for new lenses, after a few months through it usually drops slightly.Looks like you should buy now if you want to save around $ 1000 and don't mind the "Mk I" version (which is a very good lens!).
