About the maximum adjustment range
The V shift and H shift with the lens shift block is realized by changing the area used in the round-shaped
lens. Therefore, the maximum adjustment range becomes as shown in the following illustration (image).
On the other hand, it is mechanically possible to adjust the V shift and H shift over the maximum adjust-
ment range.
The lens shift amount (%) is indicated by the proportion assuming that the “height” or “width” of the
projected image is 100%. If the V shift or H shift is moved over the maximum adjustment range, the
image degradation or vignetting (lack of image) in the outer edge portion may occur, or the image center
position may not be adjusted when zooming. There is no problem to use them over the maximum adjust-
ment range if you understand these conditions. However, it is recommended to use them within the maxi-
mum adjustment range for ordinary purposes.
