K-x Vs K-7 Night Scene ISO Shootout @ DC Watch

The Japanese Impress DC Watch has published a shootout of the above for a single scene, with quite a number of different combinations of ISO and NR settings, which is quite interesting:-

(Or the English Translated Page Here)

Do note all the differences and compare, measurabate, observe and make up your own conclusions by yourself. I again let you to do your homework and decide yourself and I won't spoil their test and results here (and better to save some of my time, too :-)) Enjoy!

if K-x was able to shoot 1080p, I never ever thought about any other camera

720p is quite good enough actually. No problem and actually sharp image when viewed on a 42" panel at 3m or so. The main problem of K-x (or actually all DSLRs) for video is no realtime continuous AF which decrease image sharpness. And the Motion Jpeg is really not an efficient format and the video file is just too large.

It's not too large at all. Raw video data is always large, but not meant to be used as is. Better to have very high quality source material to work with, then encode later when production is done. I used to make gaming movies before, and exported at 2560x1600@ up to 1000 FPS, that's gives a lot bigger files :P

and exactly because of that, even a DV Canon camcorder performs better HD recording and AF (at least in Youtube test shots) but huge disappoint about color accuracy and low-light. it seems for one who wants both pro-photo/video features, at low price, there is not any bargain

KX iso 1600 is fantastic for me, but little soft in comparison of k-7, i put the k-7 image into the Neat Image and result still not so good, the higher iso comparison not to leave any chance to k-7

This time I found K-7 images have better fidelity, although noise starts appear at shadow areas from ISO 400.

K-7 much better up to 800. Above 1600, K-x better. Who shoots in 1600's consistently? I sure hell don't.

Pictures from K7 look better up to ISO 800.
Above ISO 1600, K-x JPEGs are better. But in RAW i'm not sure... Dpreview shows that K-7 Samsung sensor RAW noise is the same than Sony sensor.
See RAW nois graph in this page : http://www.dpreview.com/reviews/pentaxk7/page16.a...
