I think they changed it on the K01/K30 (in video mode only) to combat the noise from the SR system when recording. Babies and bathwater spring to mind though, as the mechnical video SR is much better IMO.

This is all very well, but I haven't ever seen the point of switching from system to system when something new comes out. Next week it will be something else anyway.
It's probably very boring to some, but I use cameras to make images. Upgrading happens when needed because something breaks or because I get a sudden twitchy mouse finger on Amazon...
As for CSCs, there was one sat on my shelf a couple of days ago. Other marques are off topic, but suffice it to say that with lens it was only slightly less bulky than a K-50. It also didn't work. Dead as a dodo straight out of the box.
Switching bodies sounds fine in principle, but what about the lenses? You buy into a system as a whole, not because body X happens to be a cintilla better than body Y. I can't see Nikonians deserting in droves to Pentax.This is all very well, but I haven't ever seen the point of switching from system to system when something new comes out.

On what evidence are you basing this ridiculous comment on?
On reading numerous forum comments where people say they have bought a crop sensor camera but intend to get a FF when finances allow... and are already amassing FF compatible lenses. Heck some people on THIS forum are already marketing their F/FA lenses in the classifieds as 'FF ready'.On what evidence are you basing this ridiculous comment on?

Yes it does, in practical terms.The size of the sensor makes no difference to the DOF whatsoever
Quote:
As sensor size increases, the depth of field will decrease for a given aperture (when filling the frame with a subject of the same size and distance). This is because larger sensors require one to get closer to their subject, or to use a longer focal length in order to fill the frame with that subject. This means that one has to use progressively smaller aperture sizes in order to maintain the same depth of field on larger sensors.
As an example calculation, if one wanted to reproduce the same perspective and depth of field on a full frame sensor as that attained using a 10 mm lens at f/11 on a camera with a 1.6X crop factor, one would need to use a 16 mm lens and an aperture of roughly f/18. Alternatively, if one used a 50 mm f/1.4 lens on a full frame sensor, this would produce a depth of field so shallow it would require an aperture of 0.9 on a camera with a 1.6X crop factor — not possible with consumer lenses! - See more at: http://www.cambridgeincolour.com/tutorials/digital-camera-sensor-size.htm#sthash.H6dInnij.dpuf
Enough technical stuff that makes my head hurt. You can just see abundant evidence of the shallower DOF a FF sensor can produce if you look through the full frame thoughts thread on the other forum.As sensor size increases, the depth of field will decrease for a given aperture (when filling the frame with a subject of the same size and distance).

Appreciably shallower DOF than possible on APSC. I'm looking forward to seeing all the brilliant FF pictures that couldn't be taken on APS-C

On the K3 you'll be able to load a Flucard in the spare SD slot and connect the camera to any android/apple/windows tablet or phone.
Edit, I think you probably can also use it on the single slot K5, but you'll be limited to the capacity of the Flucard.

Comparing the 645D to FF is apples and oranges. Plus if the Pentax FF userbase is small, how small do you think the 645D user base is going to be?
Should the K3 capture a lot of interest (and hopefully some market share) maybe an FF will be on the cards. I believe Pentax will always struggle a bit, though, without an FF body to put at the top of the Xmas tree. People invest in APSC kit with an eye to one day going FF... which is one of the reasons they go with Canikon.

Isn't this comparison a bit like pointing out the price of a Lambhorgini to try and prove Volvos are cheap?
