Originally posted by ecoronin I currently have a Nikon D40 with only the kit lens so Im not that well invested in the system. Have been looking at changing from Nikon to Pentax. Pentax is more in my price range for lenses than any good name brand Nikon glass. Also I love primes and Pentax has lots more than Nikon, and the pancake lenses look really attractive. I do a lot of outdoor photography with hiking and bike touring in mind. Weather proofing is a huge issue. I am well aware of the issues with auto focus problems.
Hi, welcome to the forum!
The DA limiteds on a K20D will give you years of brilliant images, and are great, small lenses to carry backpacking.
The DA* 16-50 2.8 & DA* 50-135 2.8 are weather sealed, and among the best zooms money can buy from any manufacturer.
The Super Takumar, K, M, and A manual focus lenses can be bought relatively cheaply, and some of them are simply exceptional.
I have a Nikon system also (D90 + some lenses,) and really, my K20D system is superior in almost every way besides AF-lock speed, and maybe flash (but I don't use flash.)
I think you're heading in the right direction, be sure to post specific lens questions you may have in the lens section and body questions in the DSLR section of the forum.
