I owned the 90mm TS-E for a year (and will one day own it again)...
And I currently own the 45mm TS-E, which I quite like (and got it to replace the 90mm TS-E because the focal length of 45mm was more useful to me in many situations)....
I think both lenses are pretty darn amazing as it is. Yeah, they could have the improved movement range, but optically they're great already. I'd probably NOT upgrade to the L version of the 45mm, and would most likely go back for the non L version of the 90mm as well.
Two remarks here:
- 24-70 II start shipping on September-October (at least, current statement says so)
- the sharpest Canon lens is 100L and I doubt TS-E 90 can beat that
and guys, as I'm looking for a new lens, can you please shortly describe (with photos as well) what you need TS lenses for? I can afford any of them, but I'm worried if I will ever use one...
kirillica - sharpness is not ultimately that important of a factor when determining the "best" qualities of a lens. The 100L might be one of the sharpest Canon lenses, but so what? What about other functionality? Like contrast, color, focus speed, durability, CA, vignette, bokeh, aperture, IS? I can promise you THIS though, the 100L certainly cannot tilt, or shift .
If you don't know what you'd use this lens for, then I assure you, you don't need one.
I used mine for some product shots, but also mainly used it for unique perspectives and portraits. But traded it (the 90mm version) for the 45mm version so I could use it for more things like group shots and environmental portraits. But I still love the unique charm of the 90mm. And I'll get it again next year.
