Hi -- Very close to 2:1 ratio. Plus a bit... For instance double 50mm, add a bit, and the 105mm has very close to the same angle of view -- at least going by diagonal lengths, since they have different proportions.
For your 35mm equivalent angle of view you have two choices in the P67: The older and much less expensive 75mm f/4.5 and the latest hot stuff and more expensive 75mm f/2.8 AL aspheric. I have the latter and it's a wonderful lense except for a touch of barrel distortion. Pentax specs say it has a 61° angle of view, which is a touch narrower than the 63° usually quoted for a 35mm, but it seems the same to me. I hear the f/4.5 is more closely rectilinear, therefore preferred for architectural photography for instance. Also there's a third choice, more obscure and also expensive; the perspective control 75mm f/4.5 with pre-set diaphragm. The excellent 55mm f/4 or the older f/3.5 gets you wider, more into the 26-27mm equivalent range. Enjoy your shopping!
