I have become a little paranoid about dust recently, and changing lenses in the field (literally sometimes) seems to encourage it a lot. For most situations, I think I could have a couple of lens in place and avoid the lens changing.
Am I being paranoid, or will enough money spent get me the zoom of my dreams, without losing much quality. (Would really like a 18-135 range to avoid the lens changing issue.)
I often carry two bodies. I recently bought an a6000 and it has become the preferred second body because it's so much lighter than my K20D, and image quality matches my K-3. I quite often carry a small kit instead of a DSLR, a6000 with 16-50 instead of a compact, or a6000 with the very fine Zeiss Touit lenses. I will not be giving up my K-3 however. No MILC can match it for telephoto or action.
There's no need to be paranoid about lens changes, just use good technique to minimize the occurrence of dust. The camera's dust removal system works very well if you do have an issue, and worse case scenario, sensor cleaning is not that difficult. I change lenses a lot and I've not had to clean my K-3 since I got it in November. Most of my bodies have needed intrusive sensor cleaning about once a year.
An 18-135mm is a nice lens to have in the bag, for its range, quiet AF and weather resistance. IQ is good, if you need pristine IQ, use a prime.
Originally posted by JimmyDranox If you want to buy a second body, why a Sony A 6000. It will not work with Pentax lenses.
Any Pentax lens can be mounted on an a6000 with a suitable adapter. Metering is automatic, and you can use P-mode, S-mode and even M-mode with auto ISO. Aperture is controlled on the adapter or lens. There are also adapters that let you mount full-frame lenses and have FF equivalent coverage. No auto-focus with any adapters.

Not if the zooms are kit zooms, but if you mean better zooms like DA*, then I agree.
