Originally posted by artificialillum So for those who are interested, I did a comparison of the K20D and Falk's K-5 image. I tried to follow Falk's processing settings (opened in CS3 with default color noise reduction (25%) and sharpening (25%, radius 1, detail 25 sharpening), saved as quality 10 jpgs, and then took samples from the JPGs at a light, medium, and dark area of the frame.
Two options:
1) It isn't, and Adam should update the post on the front page of this website...
2) High ISO on the K-7 is worse than the K20D
artificialillum, thanks for the work. While I think your general conclusions are correct more or less, I fear you made a mistake in doing the comparison.
It seems you took my other sample (the defocussed one) which is the perfect choice to compare noise at various gay levels (defocussed to hide the printer texture). However, this other sample was developed with different settings (all flat rather than default), as described in the image caption. This does affect noise comparisons.
Moreover, around ISO 1600, the K-7's SNR is about 1/2 stop worse than K20D (1.5dB). And the K-5's resolution is higher, translating to a 10% difference when comparing ISO.
Then, I agree that the advantage is about 1.5 - 2 stops. Adams claim is not backed by this thread. I PM'ed him. Still, he didn't change the Homepage post. He "
wants" the traffic, even if the news post isn't serious
Originally posted by macTak Falk, can you comment on the ease of SD card removal on the K-5 compared to the K-7 (which was not the greatest according to many).
I "felt" no difference to my K-7. But OTOH, I handle the SD card in my K-7 with ease now and think it should be exactly like this. My notebook's cardreader has the same "stop" and I really think it is the SD card standard (card must eject but not jump out when pressed). Don't know though.
Originally posted by solar1 there is the additional (to the color sensor) new 'light wave sensor" for faster AF, stated in the Pentax imaging K5 video.
Nic, I don't know about a "light wave sensor". And don't force me to watch the video with the clueless Pentax clowns.
