First days with K7, and images

It is now two weeks since I received the K-7, time to share a few first thoughts about it, as well as a few photos.

Two weeks ago, it was right in the middle of the Montreux Jazz Festival. I covered the first days with the K20D, and the last days with the K-7. I do not have a direct comparison between both cameras, as I did not want to take both cameras, but there were pretty much similar conditions on all days (all festival pics under Montreux Jazz Festival 2009).

First impressions:
  • The camera does seem to react faster. Wenn pressing a button, there is an immediate reaction. Inspecting photos on the rear screen is pretty fast, zooming is performed fast
  • The rear screen is a high res screen, allowing a better check of the photos
  • Under good light conditions, the AF seems to be of the same speed, at least with SDM lenses, as the K20D
  • Under bad light conditions, such as the festival, the AF is faster than the K20D
  • The exposure measuring seems to be more accurate. With the K20D I had to compensate between -1.7 EV and +0.3 EV at the festival, with the K7 in pretty much the same situations, I compensate between -0.7 and -0.3.
  • Exposure and AWB are more accurate
  • The 100% viewfinder is great. One does just need to remember that what he is seeing is exactly what is on the shot. The "safety" margin I was used to is gone.
  • The shutter is really much quieter
  • The dust removal is much better
  • IQ seems largely equal to K20D

I took only RAWs so far, but still around 1300, and I do convert the RAWs at the moment with the Release Candidate version of the upcoming Silkypix Developer Studio Pro which does support it.

The following photos are taken in RAW and converted with a non finished Silkypix version. I converted the photos with the default settings of the converter, without applying any other changes, and no post processing in Photoshop. This means that the first photos lack the usual final post processing.

By clicking on the small photo, you have access to the full resolution photo.

Thanks for sharing these. They're the most helpful K7 samples I have seen so far since I also shoot festivals and concerts.

tcom: could you post 100% crops of some of those black/dark backgrounds in the first few sets of photos? And perhaps anything similar you've done w/ the K20D?
Someone else posted images that seem to have a lot less chroma noise w/ the K7 on a lens cap, and your pictures would be a more real world test ;-)

Thanks for the comments.

kenyee: unfortunately, I do not have any similar shot taken in the same conditions with the K20D. If you click on a photo, you do get to the full resolution photo.

Impressively looking Iso 1600, and good seeing some real life images. (And very nice, with link to other sizes).
As I am a fan of your photography, it is great hearing your opinion on the K7

Thank you both for your comments.

Noise is definitely here at 1600iso, but is not that dramatic. The noise can be easily removed if one wants to. I do largely prefer having a file with noise and details where I can still apply the noise reduction to my liking and find a compromise between noise and details, rather than a clean high iso shot without much details.

Excellent examples of real world shots.

On the concert photos, clearly low light, how was the AF?

*scratches head* - I really, really don't understand why i've read a fair amount of negative comments about the K7's high ISO noise, these look absolutely excellent to me?
