A question to all the users of the TS-E 90 lens: Is the shift function useful in this lens?
According to calculations, a full shift on this lens only corrects for some 7° of converging lines. Is that important or even noticeable?
(Obviously shift is important for the wide-angle TS-E-s, as shift corrects for ~38° on the 17mm)
I just get Canon TS-e 24 mm. F/ 3.5 L MK II 3 months ago and Enjoy Shift Function in Architectural Photography of Tall Building= Perspective control = A++.
And I use straight 24 MM wide Angle ( with out T & S ) for my best Wide angle Scenery Shot with Best Corner to corner Sharpest , best of of My L Lenses, And Contrast in Color are Super Beautiful.
Yes, The Shift Functions are great to take 3 Photos at same location , on tripods ( at F = 8.0)---Start from Left Shift , Mid way and Right end Shift--And Use 3 photos in Photoshop / Photomerge, And Get the best Super Wide angle = 2.5 to 3 time of MP , for print 36 " X 60 " photo = Super Sharp in details from corner to corner.
Yes, I still in the Learning Period to use the Tilt Function of this Great Lens.
The Attached are the Photos of Hand Held Shooting of Shift Function Usage. ( The Traffic Police hate us to use the Big Tripods on the Public Side Walk or on the Street of Downtown area---for Safety Purpose of the public).
Enjoy your new great TS-E 90 mm.
Yes, All TS-e Lenses must use Manual Focus----I just set my Canon 5D MK II at 1 center Spot Focus and Set up The Beeping Sound---I just point the center one spot focus at the edge of buildind ( High Contrast area )and turn the focus ring untill the camera Beeping sound and the bright Green Square at the center light up= the Correct Focus for this Photos, And I just move the Camera for the best Composition.http://www.dpreview.com/lensreviews/canon_24_3p5_tse_c10/5
