I made up my mind to finally buy the pentax 28-105mm f3.2-4.5 (silver & black), which goes for about $209. Everywhere I look, it's out of stock. Ok, so it's popular.

Then I see these other flavors: 28-105mm f4-5.6 (silver & black also) sometimes priced similarly as above but easily found for less at $160ish, logically.

Then, I see a solid black 28-105mm f4-5.6 priced at around $400. What's the deal here? There is no apparent improvement in capability, yet it is way more expensive than the well-reputed 28-105mm f3.2-4.5.

Any ideas?

One of them is the Power Zoom version I think - has a big focus motor hanging on it... that would probably be the expensive one

ok, that makes sense. although, I don't think power zooms were that desireable; can't imagine wanting to pay $200 extra for the feature.

only a quick google, but it is a start. The power zoom is for the ZX only.

Power zoom works on film cameras only, PZ-1, MZ-S and other MZ, MX cameras and will also work on the new K10D. I have found it to be a handy feature, and it can be used for special effects on single or double exposure photos.
