I have ordered the 50-300 PLM and the 20-40 on Amazon.ca and will return the old 55-300 to the camera shop.
Here are the basic settings I recommend for your KP: First, put your Mode dial on "P" operation. Then go to the Custom Image menus and set the Sharpening to Fine Sharpening, in both the "Bright" and "Natural" categories by using your thumb dial to put an "F" by the "S". You access these menus through the quick access screen, which you bring up with the "info" button. Now the 4 buttons surrounding the "ok" button are used to navigate and for changing settings. Custom Image should be the first section, and the camera should already be set to the "Bright" category by default. Hit "ok" to display all categories, and "info" again to open that category.
In the "Bright" category, you will notice that the level of Sharpening is by default up one notch to +1. Leave it that way, but just add the Fine Sharpening also, then hit "ok". Then navigate to the next "Natural" category, and you will see Sharpening is not up by one notch, so you can advance it up to +1 yourself before adding Fine Sharpening. Then hit "ok" Now be sure to navigate back, putting the camera back on the "Bright" category, because this provides bast results for most shooting needs. Then hit the "menu" button to exit, or turn off the camera.
These settings will apply to the P, Av, Tv, Sv. Tav, and M modes, and will provide superior detail in your images right out of the camera. The KP has exceptionally fine internal processing. Avoid shooting in the green "Auto" mode, as many features and adjustments are then not available to you, which includes the Pentax Hyper System, and it may also choose alternative Custom Image categories decided upon by the camera's automation. The green "Auto" mode is basically there for occasions where you temporarily hand the camera to someone who doesn't know anything about it, to make sure those controls and features are not active, just in case that person might accidentally hit a wrong button or dial. For full automation where the camera is setting both the aperture and the shutter speed for "correct" exposure, use "P' mode.
I have used these same settings for years, through numerous Pentax models, with fine results, and there have been subsequent independent test reviews that have the same recommendations for both the KP and for the K-70.
