When a DA★-, DA Limited- or DA-series lens is mounted on the K-1 Mark II, its Crop mode automatically switches an image area to the APS-C size covering the middle section of the image field, while displaying the cropping frame in the viewfinder. It not only assures high-resolution images with approximately 15.36 effective megapixels, but also provides an efficient AF sensor coverage of the image area for more flexible image composition during autofocus operation. When you select the FF (Full Frame) setting of the Crop mode, you can even capture a 35mm full-frame image with a DA-series lens.
It's an APS-C lens, what's the point of showing it next to a full frame K1II ?
