ALL Pentax lenses should be WR. Maybe the DAL kit lenses can stay non-WR just for lower entry cost.
Fog is a magnet for my camera, producing a whole class of images that I find irresistible, but it drenches all my equipment. At least it's not salt water spray, which I have to watch out for during my expeditions to beaches and tidal pools. My trips to the desert require dealing with dust, which just my walking about stirs up into a cloud of helicoid-abrading and sensor-spotting evilness.
Back when I started with film SLRs (a Mamiya/Sekor 1000DTL), cameras had rather simple mechanics, very little electronics (light meter sensor, meter indicator, battery), and were thus inherently more rugged than today's DSLRs, which are full of electronics and many small moving parts. My friends and I took our cameras to the North Shore of Oahu, slapped on our cheap 400mm preset lenses, and took surfing pictures. At the end of the day, a wipe with a damp towel, and a careful cleaning of the salt spray off the front of the lens. The next day, it was off to shoot motorcycle racing for Hawaii Raceway Magazine, out on the track right next to the bikes hurtling by. There, I learned how to change M42 lenses on the dead run through the dust clouds, as I lined up for a close-in wideangle shot 4 feet from flying bikes, or a telephoto shot of a tangle of bikes exiting the straightaway. At the end of the day, bring out the damp cloth for the outside, and the blower with camel-hair brush for the inside.
I went Pentax, and eventually ended up with a fleet of M-series lenses to go with my LX. A very rugged equipment set that I could count on at the beach, on drizzly days, when there was a fog hovering above the snow, anytime. Clean at the end of the day, keep going.
Although I now shoot only digital, I expect that my equipment will still be able to get the pictures that I want. WR is a requirement for my confidence in my equipment, and, for me, merely brings equipment survivability back to the level of those old film SLRs. DSLR equipment without WR requires babying to avoid equipment failure. Covers for bodies and lenses are awkward, and if they get some water inside, can actually increase the damage. And avoiding those great situations is not satisfactory at all.
My 2nd DA lens was the 55-300, to complement the 18-55 kit lens on my K100D. I took this combo to the beach, but felt antsy about the lack of protection for the electronics and mechanics in the system from the salt and sand. I eventually got an old K200D, a 18-55 WR, and a 50-200 WR as my inexpensive, yet rugged, "beach kit". Not quite wide enough, not quite long enough, not quite sharp enough, but it's "WR" and fairly expendable. With this kit, I'll wade into the waves washing up the beach to get images that unprotected equipment won't survive. This summer, my new K5 will take over for the K200D at the beach. (I'm not talking about getting "into" the waves themselves, just up to about mid-calf. For "into" the waves, I'll get something like a WG-2.)
The K200D won't be put to pasture just yet. I also want to use some of my sharper M and A-series primes out in the beach wash zone. I recently got some O-rings to fill that unsealed gap between the lens and the camera body (where the "A" contacts are). Some experiments will determine if they can reliably keep salt spray from penetrating that gap and getting into the camera, where major damage could be done. I'll risk the K200D rather than the K5 until I know whether this sealing is effective.
Oh, I'm supposed to select a few lenses that REALLY need to be WR? OK. As others have mentioned, the DA 55-300 should be WR. Maybe the DAL version can stay non-WR as a lower cost kit lens. The wide zoom, currently the DA 12-24, needs to go WR. Of course, if it's the current 12-24 rather than its upcoming successor that goes WR, I'll be pissed, because I've had my DA 12-24 for only 2 months and I have to keep it safe from those nasty water drops and desert dust. Unless Pentax makes a WR retrofit kit for DA lenses.
I don't see any excuse why the "Limited" lenses are not becoming WR. Without WR, I just don't see them as top of the line for my purposes, and have been reluctant to buy into them. I agree with RobA_Oz, who expects that WR will become the norm in equipment at the DSLR level. I don't want to put my money into "Limited" lenses that will soon be replaced by "Limited WR" lenses. I have my M and A-series lenses to tide me over until WR is more the norm in primes.
