German Color Foto claims K-3 makes any lens a shift lens

Maybe I missed something in the specs and also in the many threads and posts about the K-3?

The well known German photographic magazine Color Foto introduces the K-3 on their web site, where they explain one sensational new feature mentioned neither in the specs, nor in the many other previews. Either they are wrong, or Pentax missed in the official specifications. The fact that the previews do not mention it, could be due to the fact that they all used pre-production bodies (they admitted that some features in the menues were still disabled).

Color Foto tells that the user can shift the sensor horizontally and vertically by 1.5mm each in 24 steps, making any ordinary lens a shift lens.

Well technically that was true for the k-5II and k-5 and I think the k-30 also. Not sure if they go as far as 1.5mm, but they allowed frame adjustment for minor shifting.

@JinDesu

I don't own a K-5, so I didn't know.
But they call it an enhanced sensor shift, so it probably can get better usage now.

Here is the reference from the forum. Only reason why I remember it was because of this article.

Composition Adjustment: old news. Been there since the K-7. From the Imaging Resource K-5 review:

Pentax K-5 Review: Full Review - Liveview
Compared to the K-7, the Pentax K-5 allows an even greater range of adjustment, so long as you don't use the rotational correction -- as far as 1.5mm (24 steps) away from centered in either the horizontal or vertical axes. If the sensor is rotated even by one step, the adjustment range reverts to the same as that of the K-7 -- 1mm (16 steps) in any direction.The level of rotational adjustment is unchanged, at approximately one degree (8 steps) on either side of level. A nice touch is that the K-5 now indicates the level of adjustment that you've made, allowing you to remain aware of how much further adjustment is possible.

Thank you.

So Color Foto have missed that Pentax increased the shift range from K-7 -> K-5.

It's certainly been there since the K-7 I wrote about using it in 2010 Pentax K-7 Sensor shift (Composition adjust) | Wallace Koopmans Artlog

doesn't the usage of the word "shift lens" in the article suggest that you can use the sensor shift to correct perspective distortion? (which is something the sensor shift can't do afaik, or can it?)

Correcting perspective distortion is done by keeping the sensor parallel with the subject. Normally an image requires the camera being tilted up to capture the entire subject (e.g. for architecture) and as such the sensor is no longer parallel to the subject. Shifting either the sensor or the lens means the camera either does not need to be tilted up or much less so. Of course lens shift can achieve a much more significant effect than sensor shift, but in principle both have similar effect. As such the statement can be considered correct. In practice, however, shifting the sensor is more about adjusting framing while on a tripod without having to move the tripod.

I don't think the German translation is misleading. I tells it exactly as Ishpuini explains it.

What they obviously got wrong is the "enhanced shift capabilty" of the K-3.
It seems the enhancement was done from K-7 to K-5, not from K-5 to K-3.
