Continuing the move toward cameras without optical low-pass filters, Pentax last year released two versions of its flagship digital SLR, the K-5 II and K-5 II S, the latter with no OLPF. Both cameras retain the same body and 16MP resolution, but get an upgraded autofocus sensor and a new air-gapless LCD. We've started our review, but wanted to put up a quick look exploring whether there's a difference between the two in terms of image quality. Click on the link below to see whether removing the low pass filter makes sufficient difference to warrant the risk of moiré.

The Pentax K-5 II and K-5 II S are identical save for the lack of a low-pass filter in the latter. Our main question was what difference we could find between the two in terms of detail and moiré. Click the image above to see what we found.
