I have an example of how amazingly low shadow noise is on the K-5 in my review: http://enticingthelight.com/2010/12/01/review-pentax-k-5/#raw For those who don't want to click through, here is the evidence (warning, full-rez files): Image as shot:

Hello Tim, can you please explain the HUGE, BIG Difference in Improved Low Light Performance you got from your K-5 vs the K20D for the same photo situation by showing us some examples in terms of ISO, f-stop, shutter speed etc or photos. Regards. Bipin - from a far away enchanting land. -- PDML

Bipin, I don't have any exact side by side comparisons, but if you go to: http://www.flickr.com/photos/ellarsee/collections/72157603434373350/ you can see pictures taken in similar situations with different cameras. In order to fully appreciate them, you'll need to use the fluidr interface for

I confess I’ve never really done A-B comparisons. But here are some pictures that couldn’t have been taken on any camera I’ve owned prior to the K-5: ISO 3200: http://goo.gl/9G9eu, http://goo.gl/7CwWU ISO 6400: http://goo.gl/9SsZQ, http://goo.gl/2wT7s, http://goo.gl/t4vlF, http://goo.gl/xQ5SK

In the Something to think about. thread I opined that the D800E was likely to be in my upward growth path for more useable resolution in the type of studio shooting I'm doing lately. A few kind PDMLers suggested that the K-5 might give me what I'm looking for and sent me some RAW and high-rez

I moved to a K-5 from a K20 and the big difference - for me, huge - was the improved low-light performance. For someone like me who finds not plans pictures, and who hates flashes anyhow, it really is a big deal. -T On Sun, May 20, 2012 at 9:08 AM, Bruce Walker bruce.wal...@gmail.com wrote: In

I'm not surprised the resolution difference is minimal and all but disappears when you compare linear resolution. The place the K-5 shines is in high ISO low light shooting as far as IQ is concerned. Studio shooting with plenty of light you might as well stick with the K20D. There are only

Assuming perfect lenses it doesn't improve that much. I can say right now my lenses and the K20D sensor are better than my technique will show. On 5/20/2012 1:50 PM, Larry Colen wrote: On May 20, 2012, at 9:56 AM, Boris Liberman wrote: I remember a long time ago, before digital kicked in,

You won't notice any difference in noise between the K5 and K20D at ISO 200 in flat light. But when I have to use fill in conversion or brighten shadows with dodging, I find that those actions will generate significant noise in the K20 or K7 image but not in the K5 pic. And the few extra
