K-5 vs D700
Tonight a friend and I did a quick, very informal, comparison of D700 vs K-5 high ISO. My first surprise was the the D700 only goes up to 6400 without going to expanded ISO. He had a f/2.8 lens of about the same FoV range as the 16-50 on the K-5, so we used those lenses, at approximately the same Field of View, at the same f/stop, and the same shutter speed. Photographing a pair of sandals in the shoe rack, indoors, the D700, at full crop, ISO 6400, f/2.8, 1/80 had better performance than the K-5. But not as much better as one might expect. We then shot a fence and building across the parking lot, ISO 6400, f/2.8, 1/15, and the gap narrowed considerably, and in color noise, the K-5 may have just slightly edged ahead of the D700. As anyone who has ever been near a D700 used to take a picture would expect, the K-5 was much quieter, maybe 1/4 as loud. -- Larry Colen l...@red4est.com sent from i4est -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

What does expanded ISO mean in this context; is it Nikonese? -T On Wed, Mar 16, 2011 at 2:51 AM, Larry Colen l...@red4est.com wrote: Tonight a friend and I did a quick, very informal, comparison of D700 vs K-5 high ISO.

It means you manually have to unlock higher than 6400iso. 2011/3/16 Tim Bray tb...@textuality.com: What does expanded ISO mean in this context; is it Nikonese? -T On Wed, Mar 16, 2011 at 2:51 AM, Larry Colen l...@red4est.com wrote: Tonight a friend and I did a quick, very informal, comparison of D700 vs K-5 high ISO.
