Originally posted by tjk911 I have both the display screens of the D7k and K20D down to lowest, but it seems like the D7k is brighter and consistently "brightens" photos. When I pop it onto my computer, images tend to be fairly darker.
This could be due to the Nikon having a 921k-dot lcd compared to the K20D's 230k-screen when viewing in camera. So no amount of tweaking the brightness settings will work since the effective number of pixels being displayed are different. BTW, the K-5 and K-r have the 921k lcd screens as well. As for downloading to the computer, the D7000 is known to slightly overexpose, so that might be a reason for the brighter images.
Anyhow, I've owned a K-5 and D7000 as well. I agree with what most everyone have said. For my hands (small glove sizes), the K-5 felt better ergonomically. Although I liked the dual SD card slots of the D7000, it made the grip fatter and I felt I didn't have as secure a grip as i did with the K-5.
Nikon's SWM lenses destroy Pentax's SDM in terms of speed and accuracy. Screw-drive lenses are about the same when it comes to AF speed. However, there is nothing on the Nikon side that's equivalent to any of the Pentax Limited lenses. I never realized how unique or light-weight the Limiteds were until I started shooting with Nikon.
A lot of people talk about lens choices and how Nikon has more, but in reality, if we're talking lenses specifically for cropped sensors (like the K-5 or D7000), Pentax still outnumbers either Nikon or Canon. Off the top of my head:
DA/DFA 15, 21, 35, 40, 55, 70, 100, 200, 300, 11-17, 12-24, 16-50, 18-55, 18-135, 50-135, 50-200, 55-300, 60-250.
In comparison Nikon's DX lineup:
DX 10.5, 35, 50, 85, 10-24, 12-24, 18-55, 16-85, 17-55, 18-105, 18-200, 55-200, 55-300.
But of course, you can always use Nikon's full frame lenses on the APS-C bodies
