Originally posted by lytrytyr Well, based on my K-01 experience:
1. No mirror slap, so you can use lower shutter speeds hand-held,
which is great in low light.
2. You can get precise manual focusing, even with a lens at f/1.2,
which is great in low light. (Did I say that already?)
3. CDAF focuses accurately with lenses like the Tamron 17-50,
which are hard to get adjusted properly for PDAF on a DSLR.
4. You can use lenses that would foul the mirror on a DSLR.
5. You can photograph from angles and places
where you couldn't get your head behind the eyepiece of a viewfinder.
YMMV.
This issue is definitely a matter of YMMV.
1. The K-5 and II series has barely any mirror slap. The mechanism is so smooth there is no discernible effect on either handholding or tripod shooting without the 2 second shutter delay.
2. The K-5 II is brilliantly and consistently accurate even when focusing through the dark and small OVF at night or indoors. Of course, there is also LV on the camera, which works well as an EVF and is just as good at nailing focus on this camera.
3. None of my lenses, including the Tamron ones, have needed any fine AF adjustment on my K-5 IIs.
4. There aren't any K-mount lenses I would like to use but cannot on my K-5 IIs.
5. That's what LV is for. I use it perhaps 5-10% of the time for those high/low angles and on the K-5 II/s it is fast, accurate and easy to use.
It may sound like I'm harping on about how great the K-5 II is, but in so many ways, this is the APS-C camera that so many pentaxians were waiting for, ever since the K10D. Now that it's here, all we want now is a D800 competitor.
We can be helplessly discontent, striving for the next development seems to pervade our human condition. Whilst this isn't necessarily a bad thing, it does make us forget the excellent developments we have available to us this very day, which is capable of so much, but the capability has not yet been tapped into.
Ash.
