OK - I think I am finally over my pre-buyer's remorse, which caused me to question the quality of the K-5 and to try to find an issue there. I know that all consumer products can have problems and that forums magnify the few that do occur. The K-5 looks awesome and the support of its many happy owners has let me get past that now.
I do want to visit my local camera shop though and maybe get it there just in case I do have any issues.
So I have homed in on three lens choices, and any suggestions would be greatly appreciated.
1. I could just get the kit 18-55 mm lens while I sort out what I really want in the way of zooms. (suggested several times)
2. I could get the 18-135 mm lens and cover the whole walkabout option with just one lens, but which is still just as slow as the 18-55 mm kit lens.
3. I could go crazy and get both the 16-50mm f2.8 and the 50-135mm f2.8 and have two excellent quality lenses that cover the whole zoom range, but at a significant cost increase.
I have noticed that a lot of people that own the K-5 think that the slower lenses are quite acceptable when mounted on the K-5. If I don't need the f2.8 lenses with this camera, I would rather save the money for some nice primes later on. But I can suck it up and get #3 if that is what I will ultimately end up needing.
Thanks for listening and offering your opinions.
