Originally posted by calsan PentaxForums tends to live in a bubble. This is what a real, honest review looks like. It's not normal to have the site's head fanboy give a handjob to every mediocre product that passes through his hands. Or rather it sadly is in certain circles (Ken Rockwell with Nikon, Steve Huff particularly with Leica, etc) but you'd best take the "pros" with a grain of salt and read the "cons" carefully, or just read it for the technical info. Similarly when those fanboys can't find anything nice to fixate on except "it's small", it's a good time to consider the alternatives available to this $1000 lens. But just blasting reviewers in general because a lens you like performed poorly is childish and stupid, particularly given
which reviewer did this one.
To respond to the specific points above: the first article is asking "what is the point of this lens existing?" 15mm is a niche that is already hugely covered in Pentax's lineup, and a lens that is better (faster, internal focusing, etc) with a nearly identical focal length was less than a year out. This is ignoring the
gobs of 10-20mm type (8-16, etc) wide-zooms out there. It's reviewer's job to help their readers not waste their money, including asking "why?" at times.
The second article is Photozone, and their technical analysis is really not to be called into question. They get it right far, far, far more often than they mess it up. If they say that it's nothing exceptional, maybe they got a bad copy, but their copy probably is not the best lens they've seen in the world. Pretty much any lens produced by a camera manufacturer in the last 20 years is "good enough". You can make great photos with a kit lens, and you can enjoy the photos you've taken. But it doesn't mean that a kit lens is a fabulous optic producing superior resolution - at normal screen or print sizes, anything less than mushes of color will be non-distracting at least. If all you want is some pretty pictures from the lens, Photozone has that too, as does every other review.
As described in the review, the optics aren't
repellant. They behave a lot like a kit lens - stopping down is highly suggested for good optical performance, particularly on the long end. In that light it's an OK lens, although corner issues are still disappointing and it's kind of a poor overall performance for a limited-range zoom The problem is asking big-boy bucks for them - that much cash could buy a real pro-grade zoom or a used full frame body instead of a warmed-over kit lens And yes, if you want to spend $1000 you can certainly get metal-bodied lenses if that turns your crank.. If you showed up with one of these at a wedding you'd get laughed out, and that's range this lens is priced at. Heck, these days $250 buys you a used Tamron 17-50 f/2.8 which is faster and sharper with a wider range at 1/4 the price.
