Default K5 High ISO Performance

Having owned a K10 for a number of years, I was attracted to the K5 for it's ISO performance; a recent trip to the Zoo to see their new baby elephant provided the idea occasion to push the ISO to up to 12800 in order to capture a number of shots on a dull overcast day with poor lighting.

Noise is present but processed in LightRoom 3.6 & exported into PS CS5 as PSD files to be processed give results that would have been impossible with the K10.

AS Patty said .. nice sharp shots. The lack of noise (or otherwise visible noise) often has a lot to do with the background, amount of sky, shadow etc. in the shot but the K5 is wonderful in reducing it to a minimum and the amount of time I spend reducing noise in shots and then re-sharpening, compared to the K7, is down by 90% !

Tip. When shooting zoo shots try to keep visible signs of being in a zoo (anything man-made, worn paths etc.) out of the shot to make them as natural as possible. Those look like very healthy and good condition animals.

Wonderful shots! I always love flamingos, so I guess that's my favorite.
