Pentax K-5 II and K-5 II S: Digital Photography Review

Resolution Chart Comparison (RAW)

On this page we're looking at Raw resolution for both the K-5 II and K-5 IIS. For a (more) level playing field we convert the files using Adobe Camera Raw. Because Adobe Camera Raw applies different levels of sharpening to different cameras we use the following workflow for these conversions:

Load RAW file into Adobe Camera RAW (Auto mode disabled)
Set Sharpness to 0 (all other settings default)
Open file to Photoshop
Apply an Unsharp mask tuned to the camera, in this case 100%, Radius 0.6, Threshold 0
Save as a TIFF (for cropping) and as a JPEG quality 11 for download

K-5 II	K-5 IIS

Both cameras used the 50mm F2.8 Macro lens at F5.6. We see slightly more resolution in the raw output from both cameras, with the K-5 II managing to resolve well up to around 2200LPH and the K-5 IIS just a little more, towards 2300LPH. Moiré quickly takes over as lines get closer together in the K-5 IIS, shown as slight coloration that appears well beyond the 2000LPH shown in this crop, an effect that is better controlled on the K-5 II.

I heard and read alot about this pentax. and I believe it is a very good camera. what I know is that pentax k-5II is better regarding the details of the photo. and D7100 is better regarding the colors and the auto white balance. do you think the pentax is better is other situations?

The S has everything I need [Time Lapse too], EXCEPT a LCD that moves/articulates. . . ughhh!!!!

The auto focus in low light is better and the redesign of the rear LCD has been change for better viewing in bright light. Not much else as far as I know. I purchased the K-5II because I often take photos in low light situations and can use all the help I can get!

Seriously, what is the difference between K-5 and K-5II? Every single specification are the same.

The removal of an anti-aliasing filter. this allows for sharper images in the II but sacrifices the tendency to produce moire.
