Veteran Member Join Date: Sep 2007 Location: Dayton, Ohio | My take on the K-7 after a few months.
I wrote this as a response to a p.m.. Thought it may be helpful for others. I also want to point out, that from early on, when people were whining about high iso (some even left Pentax) , I always maintained that K-7 jpeg sucks for iso and is amazing when processed in RAW. Now, DPR has confirmed my findings.
"................Firstly, I never yearned for a higher IQ than what the K10D could deliver at iso 100 and 200 and I see absolutely no reason to upgrade for IQ. I am quickly finding out, given my yearning for the ultimate in IQ, only iso 100 and 200 are suitable with any camera however good they may be in high iso (a camera that is very good in iso 800 compared to another only means that it is less shitty at iso 800 than the other, nothing else....so, high iso comparisons IMO only compares how much less another camera sucks, as none of them give the ultimate IQ). (P.S: But, high iso is still very useful in certain situation)
Secondly, I only upgraded because I was needing a camera for my work and I bought the K-7 and use the K10D for work, so money wasn't a big decision when I bought the K-7.
But, I am so very glad I did it. The K-7 does everything the K10D can and more, what better reason to upgrade ?, and the following is my very conservative praises of the K-7 (I don't want my enthusiasm towards the camera to overemphasize the positives so I will try to hold it back a bit).
The K10D had lots of sample variations, I think (as mine had good AF even in mild darkness, except AF-C which sucked royally, and mine had random metering, except in spot metering). Compared to my K10D, the K-7 meters perfectly to my taste with and without P-TTL flash. With the K10D, every new scene needed me to take a few test shots and adjust the exposure before taking that first good shot, there is absolutely no need for that with the K-7. Metering is just as easy as pointing and shooting. (I've gotten my money's worth with this alone).
I absolutely love the AF adjustment for each lens, made a huge difference with most of my lenses.
I am not too sure about AF. In testing conditions I see a huge improvement in how fast the AF-C locks indoors, I just haven't really tested it in the field yet. I think it will be a definite improvement over the K10D. (In AF-C testing indoors, when I move my K10D from one part of the room to the other, I have to wait a bit before it locks focus on the the new scene, the K-7 most of the time is already locked focus even before my eyes drop down to check the confirmation). But, with my very limited test outdoors I am afraid it is still not perfect and my hunch is Canikons are still better at it. AF in low light is marginally better without the green assist light, but is perfect with the green assist light ON in AF-S.
High iso: IMO both the k20D and the K-7 are a definite improvement over the K10D, but then again all three give the ultimate IQ only at iso 100 and 200. But, when pushed as in say sharpening beyond good taste the K10D images at iso 100 deteriorates among the sharpening edges and start to show dark lines before showing any noise, but the K-7 images even at iso 100 will start to show noise more than just the sharpening artifacts along the edges. But, this is when pushed beyond the limits, so not overly relevant but I know there is a tremendous hidden baseline noise in the k-7 images when pushed. K-7 JPEG shows a whole lot more noise than the K10D at iso 200 and 400, but then the K10D get worse. But, when processing RAW which is what I do, I used K10D below iso 400, and I can say I easily use the K-7 upto iso 1600. For faces I used iso 200 and less with the K10D, and I can easily use up to iso 800 with the K-7). So, even though I only really like images shot at 100 and 200 for showcasing purposes, the higher iso definitely comes in handy for family snapshots taken without flash.
AWB is a joy and is frankly voodoo magic. I know raw wb can be changed, but I never could get the skin tones correct in RAW when the WB is messed up indoors, the K-7 has perfect AWB indoors. So, WB is also as simple as just pointing the camera and shooting. I LOVE it.
I enjoy the auto-iso feature more with the K-7, but again I am preferring to shoot at iso 100, so not very well used.
In general usability, I am loving the K-7. The minor changes to the size and shape is making a huge difference to me in daily use. I am loving the feel of the camera in my hand, and i am just shooting intuitively. Carrying the camera with the DA21 and and the FA43 (one in the pocket) is a joy, what a package.
SR is possibly improved as well. Sensor cleaning is tremendously better too.
Therefore, the K-7 has removed most of the sluggishness of the K10D. Some say they don't see much improvements in IQ with primes vs zooms or zeiss vs Tamron etc...but, I see a huge difference in IQ and rendering when it comes to lenses, but I see no IQ differences between most cameras at low iso's.
With the K-7 and the Pentax primes, I am enjoying photography more.........................
