Weather sealing user’s expectations
7 months ago

Although one user from another thread has suffered a glitch with his new K-3, he is covered and his camera will be replaced.

It is still well under warranty and the local supplier is nothing short of amazing in providing exceptional customer service.

However, this is an opportunity for other users learn a few valuable tips before the purchase, and remember them during and after the purchase of the Pentax K-3 camera and a lens from the Pentax range.

TIP NO. 1 — WHEN WARRANTY WILL BE NULLIFIED?

Any warranty will be nullified by the manufacturer if the damage to a camera was caused by moist that creeped in when using the K-3 with a non-weather-resistant lens. It is plain common sense, right?

Not to some. Many folks expect camera to be weather-proof using any lens they have, under all weather conditions. To them, DA Limiteds, old A, M, K series of lenses and Takumars, etc. is all the same. Well, it doesn’t work like that.

Get to know your camera and your lenses first. Don’t go out in adverse weather and shoot openly exposed to elements if you don’t have a WR lens — you will most likely damage your camera and your lens. And your false expectations.

TIP NO. 2 — BE MINDFUL OF DIFFERENT WR DESIGNATIONS.

Pentax has two different WR designations:

a) WR, and

b) DA*.

WR lenses have limits as to what to expect from them. WR lenses cannot be used for a prolonged time in adverse weather. Instead of them, use DA* lenses, which were purpose-built for such use. DA* lenses have better seals overall.

In short:

  • Light rain (WR) — Prolonged use in rain (DA*)
  • Light snow (WR) – Prolonged use in snow (DA*)
  • Slightly dusty atmosphere (WR) – Prolonged use in dusty atmosphere (DA*)
  • Low temperatures use shortly (WR) — Prolonged low temperature use (DA*)

Note: None of WR, DA* lenses or the K-3 camera can be submerged in water at any time. Lenses and camera are not water-proof, they are weather resistant.

TIP NO 3. WHICH ONE TO BUY — WR or DA*?

Be sincere to yourself, and to your gear. Plan your budget carefully, and be mindful of the intended use of camera. If you really want to use camera frequently in early mornings, in adverse weather or in extremes of climate, get yourself DA* lens(es). Fo example, users living in tropics on in cold north / south, will be better suited with a DA* lens. It is much better investment, better economy and a peace of mind too, especially considering the lifetime of use of such a lens.

If you live in moderate climates and think you may occasionally take some photographs in adverse wether, but nothing too serious and all very guarded, WR lenses may be a good choice.

TIP NO. 4. TEST YOUR K-3!

If you have a WR or a DA* lens, go out and test your K-3. Be mindful of designations and what to expect from each. Do it right away, so if there is any problem with camera’s seals, you will notice it in time, and have the camera repaired or replaced when it’s still well under warranty.

TIP NO.5. EXERCISE COMMON SENSE.

Even if you think that camera and lens should perform in a certain way, don’t push it too hard and don’t be unreasonable. Many amateur users deliberately push their equipment well above limits of any common sense, and then blame the manufacturer for their own negligence and lack of respect. Firstly, take all care that you are well protected when shooting in adverse weather, and then, be mindful of your gear too. Take all reasonable precaution to help your equipment work as best as possible, by minimising adverse impact onto it. Extra covers for your camera and lenses are always recommended, same as you would wear a raincoat yourself.

TIP NO. 6. LET THE EQUIPMENT DRY WELL BEFORE OPENING.

When you come home, or into your shelter, do not unmount your lens immediately. Wipe the camera and lens with dry cloth, and let the camera and lens dry slowly and completely. Only then, after an hour or two at a stabilised temperature with no excessive humidity around that may creep inside the camera, unmount the lens.

Digital cameras are far more susceptible to moist damage than their film counterparts. Thus even when designated as weather-resistant, digital cameras are more likely to suffer from condensation if you are not conscious about

1. sudden rapid changes of temperature,

2. unmounting/mounting of lenses, and

3. changing of batteries.

Hope this will save some users unnecessary moans
