Pentax K-S2

While the K-S2 isn't waterproof, no matter how many times Chris (in the video) says it is, it certainly should be able to take a good bit of splashing, rain and perhaps even live through a dunk in the drink with a quick recovery. Watch the video for that demo.

The online prices for the Pentax K-S2 are currently:

$627 USD for the body alone.
$749 USD including the weather sealed 18-50mm lens (27.5-76.5mm)
$800 USD including both the weather sealed 18-50mm and 50-200mm (76.5-307mm) lenses
$903 USD including the weather sealed 18-135mm lens (27.5-207mm)

Pentax also has the slightly larger and much less expensive K-50 body ($295 USD), the heavier K-3 ($749 USD) and slightly upgraded K-3 II ($997 USD), which are all well weather sealed.

The entire lineup of Pentax weather resistant lenses in production is impressive:

18-55mm (27.5-84.5mm) $163 USD
50-200mm (76.5-307mm) $170 USD
18-50mm (27.5-76.5mm) $297 USD
55-300mm (84.5-460mm) $340 USD
18-135mm (27.5-207mm) $400 USD
100mm f2.8 (153mm) $547 USD
16-85mm (24.5-130mm) $647 USD
20-40mm (30.5-61.5mm) $697 USD
70-200mm f2.8 (105-300mm) $2,300 USD
150-450mm (225-675mm) $2,500 USD
560mm f5.6 (859mm) $5,000 USD
(This is just what my go-to camera store stocks. There are a few other WR Pentax lenses.)

I'm thinking about giving one of these setups a try. It would be useful on touring days when I'm not planning to get wet, not needing to keep the camera in any kind of case.

I also believe it "might" survive a roll... Extra water pressure (pushing against atmospheric pressure inside the camera) on the o-rings would be about 0.5 PSI at 1 foot depth. You'd still have to resort to your quickest roll though :D

But... my other concerns, if using this SLR while paddling on the ocean, is to have it exposed to a very salty environment for long periods of time.
I am afraid that would induce :
  • Corrosion (although, honestly, I don't know how these Pentax "WR" bodies rate in term of corrosion resistance in marine environments)
  • Salt deposits building up where metal or plastic parts are suposed to slide freely against each other, like lens and buttons (difficult to dissolve by rinsing with fresh water).

So quite risky overall in most real ocean paddling situations, except maybe the most calm seas?
(in my experience, protective housings all have the problem of fogging on their window/lens when paddling in colder climates/waters. desiccant bags are a pain to keep dry on a expedition)

I am hoping the recently released Leica X-U (Typ 113) (Can$ 4500.... :shock: ... yes... ) will be an incentive for Nikon to produce a new and better version of their AW-1 (priced in the $1000 range), or for Panasonic to make an affordable version of the X-U.
