dpreview.com page is now added with, -- AF fine-tuning.

I think that the d7000 will be frantic to impact the camera lover market.
maybe Nikon would not provide a d400? at least d400 will be delayed.

as a Pentax's user already 28 years, I have to say,

nowadays, If someone who has no Pentax lenses, absolutely you are ought to select a d7000. If I have no Pentax cameras and lenses, I would never care about a K5.

If Pentax K5 is still a higher pricing, Hoya should get hell.
d7000 body is 1200 USD, and then the K5 will be a value far less than 1000 USD.

K-5 vs. D7000

The K5 hasn't even been released yet. What makes you believe that it would be worth $200 less than the D7000? The Pentax is likely to be on par with the D7000 in most aspects except the 39-point AF, and is going to have its own advantages (in-body IS, and probably faster frame rate).

Re: two cameras compared.

two cameras compared.

-- hide signature --

Metering:

d7000, sensor -- TTL exposure metering using 2016-pixel RGB sensor, 3D color matrix metering II

Spot -- Meters 3.5 mm circle (about 2.5% of frame) centered on active focus area.

(Spot metering can synchronize with a focusing point, and that a spot metering is movable position. When your d7000 is locked to a tripod's top, that would be more helpful.)

K5, metering sensor -- like K7, Spot -- only a spot fixed.

--Autofocus:

d7000, Nikon Multi-CAM 4800DX sensor module, 39 focus points (including 9 cross-type sensors), a larger coverage area! (And, Nikon has the more reliable AF system)

K5, rumored a 18-point way, another rumored - that is still an 11-point like old AF. However, in any case also impossible to compete with d7000 39 points.

--Flash
d7000, up to 1/250 sec (up to 1/320 sec in Auto FP)

K5, 1/180 sec. (will have 1/250 available with new flashes to be released First half 2011)

--Viewfinder:
d7000 -- Frame coverage 100%
K5 -- Frame coverage 96%

--Continuous shooting
D7000 -- Max speed 6fps
K5 -- Max speed: 8fps

I have to say, that the continuous shooting with the 5fps were already sufficient, d7000 and K5 both are mainly facing the high-class camera lovers, and not the semi-pro grade DSLR, they did not need a machine-gun.

However, the mirror/shutter's oscillation must be lesser. Also, we are wanting the shutter's lag is smaller, AF is faster.

In K7, pre-focused's shutter lag time is only 67ms, not bad. But its oscillated amplitude is a unknown data. We would prefer K5 still be 5fps, and not a 8fps, K5 is having a smaller pixel size than K7, then a same oscillation amplitude would be a worse result. The worse luck -- if the oscillation amplitude moves up.

if K5 is finally 8fps, then its menu must provide an optional item, 5fps or 8fps.

a higher speed of fps and limiting of the oscillated amplitude, would be a higher cost. That is usually in a professional/semi-pro grade DSLR aspect, and not a K5, K7 or d7000.

Pentax Z1p is only a 4fps speed, but Z1p is a good camera, nobody doubts it. Historically, Eos5 is a faster 5fps, but its mirror/shutter's oscillation was very bad.

Re: two cameras compared.

PS.

If you take into account that the Nikon lenses and accessories have more advantage and easier to buy. Well, d7000 is very worth buying!

K-5 is not yet released!

You're funny, how can you compare the K-5 when it's not even released? Can you just wait till monday please? Some of the specs you wrote about the K-5 are completely off.
