After using it for a 30 days, here's what I found to like and dislike. I restrict what I assume are more crucial characteristics.
AF is fast, accurate and consistent. Not perfect, but what we found is that is predictable and consistent.
AF is really configurable involving 9pt, 21pt, 39pt and 3D dynamic. Not used yet dynamic, but 3D big factory, but as noted by Nikon, it can be fooled.
Flash is fantastic. The exposure is very accurate and consistent. It is not easily fooled by reflective objects. This is an aspect of my Pentax physiques (dl, K10, km, KX, K200), which I find to be very inconsistent.
Shutter noise is quiet, not as noisy as Kx, but not as peaceful as k7/k5.
Body size is good (for me). No body seems bulky at all. K7/k5 just "feels" more gorgeous when it occurred, Nonetheless. However, KX / km was a bit too small for me.
battery lasts very a bit on a single charge. (Do not use AA though)
Switching among AF modes (AFA, AFS, AFC Auto and single, 3D, dynamic 9pt/21pt/39pt) by pressing a button and turning the control wheel is very convenient.
MyMenu configurable - add the items most commonly used for this menu. Very nice feature.
In-VR / VC. This stabilizes also picture on VF, which in some instances can help with AF. The first time I used Tamron 70-300 VC and hit was amazing. I was ask myself, can really keep it this constant to 300? switching from VC told me my reply. No.
Switching in between manual is a PITA AutoISO and to make the menus. This is 2 or 3 button on the Pentax. To help this, I put this in MyMenu menu item to save a few button presses:
Edit: Fn button and add programming AutoISO On / Off at the top of MyMenu is effective in AutoISO toggling on / off so that it is an aversion.
When the digital camera is not able to say exactly meters beyond the range specified (in AV mode), exposure time displayed is "Lo". Why not only show exposure and flash it? "Lo" not good at all.
There is no instantaneous 100% zoom when reviewing shot taken. this is scheduled for Pentax.
No pixel mapping. This would be a nice feature to have.
The SR-Body will work with any lens mounted. If the lens has no VR / VC / OS, you will need your skill to make constant shot.
I imagined AA batteries lose Kx, but i can still use a clamp on the D7000 and LiIon battery lasts a while.
As a system, there is rather a bit more help from both Nikon and 3rd occasion vendors.
Lens assistance for example, Tamron 70-300, 18-270 and 60mm pzd. Yes, Nikon contact lenses are more expensive and high-end lenses are stratospheric, but at least they are available.
As many people have said, buy the digicam system that works for you.
So far, after one month, I like D7000 and Nikon process. There are a few quirks and afflictions, but with any program and so far I have not found any show-stoppers are. What will be my primary class to assess the number of owners until now, my rate elevated owner.
Primary lens and Tamron 16-85 and 70-300 is using VC.
