A spring fed waterfall in Northern California
Pentax 6x7 / Portra 160
— Robert Adams
If you are within reach of the Los Angeles area I would highly recommend checking out this photo show. I attended the inaugural show last year and was truly in awe by the diverse collection of extremely high caliber photographers represented at this show. It was a mind opening and inspiring experience that I lost myself within for an entire day.
I am using the Pentax 6x7 with MLU (mirror lock up) which is the 2nd version of the camera. The first being a Pentax 6x7 with no mirror lock up. There is little difference between the 6x7 MLU and 67 MLU other than age which can come into play with the longevity of the body.
I am shooting with 2 lenses as of now. The SMC Pentax 67 45mm f/4 and the Super-Multi-Coated Takumar 6x7 105mm f/2.4. Some people have come across slightly soft optics in some of the older 45’s (SMC Pentax 6x7) so I’d recommend looking for the newer (SMC Pentax 67) version of that lens or a 6x7 version that is in very good condition. As for the 105, I believe this lens is reason enough to buy into the Pentax 67 system. Sharp at small apertures and beautiful unmistakable 3D-ish looking bokeh at large apertures.
If I was to add another lens to my kit it would probably be a 200mm or 300mm f/4. There are some landscape compositions that benefit from the use of the compression characteristics of a slightly telephoto lens.
