Yep, I think it might be something of the early days of AF or the type of AF that they use.
I believe that you can look through a circular both ways but with a linear only in one way, the way the AF works in current DSLR this shouldn't be a problem.

I'm just speculating now though, do someone know the true reason?

Here is a little tip, get a linear filter instead of a circular it save you some money and the linear also work better I believe.

Aren't those weekly magazines all like that?
Reviewing the latest camera, most articles about Canon or Nikon orientated, some photoshop tricks and a some tips & tricks to do some shots.
And 12 months later they reuse almost the same article again to fill pages.

You should look at the monthly or longer magazines, like B&W they have 8 issues a year http://www.bandwmag.com/
Or silvershotz which come with 6 a year http://www.silvershotz.com/
They don't really do reviews or news article like in the weekly magazines but is more orientated on photography and on photographers.

I doesn't run on OSX right?
Id that is so the it's quite a miss though, like Photomonk says just a ipod thouch/iphone on hormones while it could be more

They should have done this if you ask me http://www.axiotron.com/
Don, I think this is what you're looking/waiting for or not?

You do know there are two pro series right the Z-pro and the X-pro.
I've the Z-pro.
I believe you can go up to 10mm on a crop sensor (15mm on 135film) with the X-pro.
The Z-pro can go up to 14mm (20mm 135film) but it can be reversed mounted and then it can go a bit further, they don't say how much but it could be wider then 10mm by the looks of it.

Yep the DA*, FA* or any other with a *star are the better lenses.

The limited series and certainly the FA ones are also very very good, and like Matt said any prime will also be better then most zooms.

Well first of all, Canon seems to sharpen their photos a bit by software, Pentax default settings with JPG is quite soft so for get that detail for now.

Pentax is now making althose classic focal lengths for APS-C sensor (1.5x crop)
The DA*50-135 f/2.8 is the digital equivalent what the 70-200mm f/2.8 was on 135mm film.
If you want that range though the only thing pentax has is the DA*60-250 f/4

The DA* (with the star) are the high grade/professional lenses, maybe not so pro as the super high end of Nikon or Canon but the price is important here, you can buy a car with some of the Canon/Nikon lenses.

"Not for ages and ages" sounds so long though, not a year...
I came to that date since the DA55-300 DAL was also launched with the K-X camera so you probably need to wait till the next WR camera is launched.

They might launch it as kit lens instead of the DA50-200.
I think early 2011 is the date.
You don't have that as option though so couldn't vote....

Then it's still under warranty of the repair... hopefully
