I am currently using a Pentax K-5 for my photography.
I also use a Leica Digilux 2.
I have a range of lenses for the Pentax ranging from a wide angle DA 14mm/2.8 through to a tele-zoom DA 55-300mm. I own a Zeiss ZK 35/2 which is a stunning lens - and one I use for a lot of my landscape and other photography.
The photograph displayed was taken with the Zeiss ZK 35/2
