Title: Tilt and shift Post by: jodaco on November 13, 2009, 07:32:45 AM Bob,
I found your write up of the tilt adapter very interesting. Going to the Kiev camera website I noticed they have a 35mm tilt and shift lens for Canon mount for only $600. In many ways this seems like a better option, especially if you don't already have a lens with separate aperature control to use, since you get variable tilt, shift and aperature control. Any chance of you getting a chance to look at one of these lenses? They are offerred in 35 and 80mm. Canon's T&S lenses are all wide angle. What would be the pluses and minuses of a longer T&S lens? Thanks for your always helpful insights -Josh Title: Re: Tilt and shift Post by: whizkid on November 13, 2009, 11:56:39 AM Just a thought but unless it is a vital image why not just use keystone correction as found in DxO Optics Pro or other software ?

Shift corrects keystoning. You can emulate it in Photoshop, but when you do so you lose some image quality in the sections of the image that you have to stretch most. For mild corrections and/or small prints it's not really an issue but for large corrections and/or large prints it can be. I think if I had $600 to spend on a T/S lens, I'd look around for a used Canon. You might have to add a few dollars, maybe another $200, but I suspect the Canon quality is higher. Wideangle T/S lenses tend to be used for landscapes and architecture. Longer forcal length T/S lenses (like the Canon 90mm) tend to be used more for product shots and closeup work |
