First see this Pentax official website:-

http://www.pentaxslr.com/lenses

Look! It is really funny that some lens hoods are misaligned, and that there are some lenses with rear caps and some don't. What a serious piece of work! And, one can see how serious the working attitude of their staff!

I previously think that I was really unlucky with all kinds of alignment problems with Pentax DSLRs and lenses in reallife. The full story is told here:-
http://www.geocities.com/ricehigh/A_...rporation.html).

It now seems that there are even more obvious "alignment" errors shown at their official Webplace in the Cyberspace. Really funny and interesting! It is very funny to learn that there is no difference between the real-world factory and virtual place of theirs afterall. However, this is a sad case indeed.

Actually, I bet that the lens hood photos are copy and paste job, as the position of the lens hood put onto the 31 Ltd. is actually impossible, for a built-in hood and so do the 16-45 one.

I think some PS work on the pics has been done to:
-show the "top" of the lens with all interesting figures and numbers
-show a more interesting view of the actual hood, two petals on each side looks slightly more interesting than a big black bulge on top....

Looks to me like they may have used a camera with swings and tilts built in so they could show the top and side at the same time. Common practice used in advertising photography using a camera with a bellows attached where the lens board can be moved around to distort perspective or in other cases to take out distortion.

I see you still visit dpreview.com, some other people over there took note of the rather weird pictures of the Pentax lens lineup.

Well, at least they took the pictures with another camera than a Pentax, because they do seem properly exposed and in focus, right Rice? :yawn:

Yep, it's still interesting to look there to see how people are prasing their gear.

They are surely still using Pentax gear and undoubtly their gear do *always* expose and focus 100% accurately.:-)

View Camera 101:

On a View Camera the lens and film aren't fixed parallel to each other. This opens up a huge range of creative opportunities that are unavailable to most photographers. For example, if you want to take a photo of a building, the obvious thing to do is point the camera up towards the center of the structure. However, this results in projecting the vertical exterior of the building onto the angled film surface. The lines of the building will converge towards the top of the frame. A view camera allows you to keep the camera level with the ground and either shift the lens up or the film down. The film is now "looking up" at the building through the lens, but the film is still parallel to the building exterior so lines don't converge. If you're taking a picture of rocks in a stream with a view camera, you can achieve sharper focus by tilting the lens forward a bit. This will get the Scheimpflug Rule working for you: the planes of the subject, the lens, and the film should all intersect in a line. You can achieve the same result by leaving the lens fixed and tilting the film standard back a bit. This will improve the focus and also increase the relative prominence of nearby rocks since they will be stretched out onto the film.

Do you mean "shift lenses" which are usually used to do serious archectiture shootings?

BTW, I think the lens photos in the pentaxslr.com are wrong just because they shooted the pics carelessly but it is not something related to shooting techniques anyway.
