But the motor isn't everything though, it's also the AF sensor and the software behind it.
Wasn't it you Amin who tried a super fast K7 demo at SRS?

Also Pentax is one of the few, maybe the only one that have lenses with SDM and screw-drive focus, many people forget about the complexity that's involved to make that work and Pentax does a double focus check where others only use one.

It truly isn't that hard.
Get this program link and follow these instructions link and you've an ISO.
Virtual drive is also easy to get there are several programs, I use Daemon tools.

WR is weather-sealed, different lens coating and has quick-shift, metal lens mount and a hood.

You don't need to write a disk!
Just create an ISO and give it that name and mount it in a virtual drive

Good memory Kris!

Yes you're right the K-M and the K-X get the DA-L lenses in their kit but the other cameras have DA lenses and the K7 even gets the DA WR version.

If you would get lenses separately you could look for the DA 16-45 instead of the 18-55, the DA 16-45 is a bit more expensive but worth the money though.

Canon lenses still come without a lens hood I believe, don't know about other makes.

As for the versions.
There are 2 version of the 55-300 lens, one is the original DA 55-300 that one comes with a hood, metal lens mount and quick-shift.
Pentax had the "brilliant" idea to remove some features to make the lens lighter and cheaper and that's the DA-L version, that one doesn't have a hood, metal lens mount or quickshift.
Optics of both versions are the same.

You can buy both version in the shop.

It's a known problem with split-screen focusing screens.

Here this how every thing is placed inside of the camera.


#1 is the exposure meter
#4 is the focusing screen
#7 is the AF sensor.
I believe the rest is quite clear.

As you can see the exposure meter must meter though the focusing screen and that's causing the problem.

Me neither at first but the search term infracolor did wonders

Good luck with the filter and post some photos because i'm interested in how they look.
I've a K10D and I've used it with a real infrared filter but the K10D isn't so infrared sensitive, but your filter might work better.

Here you go link
I guess you needed 58mm because of your Adorama link

The one on the German site is cheaper but don't know how much shipping is, no tax though since it's an EU country.

Just checked for you, it takes 2 to 3 business days and cost €6 shipment so in total €26,32 and that would be £22,63
