オートフォーカス

方式 TTL位相差検出方式:フォーカスポイント39点(うち、クロスタイプセンサー9点)、マルチCAM 4800DXオートフォーカスセンサーモジュールで検出、AF微調節可能、AF補助光(約0.5~3m)付

検出範囲 -1~+19 EV(ISO 100、常温20℃)

"AF微調節可能"

d7000, English:

http://imaging.nikon.com/products/imaging/lineup/digitalcamera/slr/d7000/spec.htm

Autofocus Nikon Multi-CAM 4800DX autofocus sensor module with TTL phase detection, finetuning, 39 focus points (including 9 cross-type sensors), and AF-assist illuminator (range approx. 0.5 to 3 m/1 ft. 8 in. to 9 ft. 10 in.)

"finetuning"

d300s, Japanese:

However, website dpreview.com page is lacking that, -- fine-tuning,

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).

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.

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!

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.
