Another advantage of the tilt / shift lens is the ability to shift the lens up, down or even left to right. The biggest advantage to shifting the lens is it gives you the ability to correct perspective. This is really helpful at eliminating the leaning effect you get when you look up at buildings, trees etc. with a wide angle lenses. I think these two images demonstrate perspective better then I can explain it. I used shift to pretty much square the Alaska State Capitol building within the frame in the above photo. Below is a much older photo of the of the same Capitol building taken from the same location with a lens that I couldn’t shift.
I think the difference is very obvious in this example.
Here is the Canon tilt / shift lens from above with the lens shifted all the way to the left.
The ability to shift is also helpful when creating panoramics. In fact the photo of Mt. McKinley in the masthead of my blog was taken with a tilt / shift lens. I didn’t move my camera, I just shifted to the left, middle and right and combined the images later in Photoshop. Photos captured this way blend together with almost zero effort since the camera isn’t re-positioned.
Yesterday’s post touched on using tilt.
