complete brain fart - is my DA 16-45 weather sealed?

Showing my age but for some reason I can't remember and or find if my Pentax DA 16-45 can handle some snow or lights rain?

Not weather sealed but some light snow or rain shouldn't be a problem if it isn't for extended periods. Also make sure to wipe it of afterwards and let it dry.

If it's snow, blow it off before you bring it inside.

But be careful, consumer zooms suck air in, so airborne moisture can get in too.

Easy way to tell: Any DA lens with a * or WR in the nomenclature is weather-sealed. All-else, take due care in austere conditions.

Maybe up for debate, although Pentax switches up their nomenclature so much it is hard to say. But to clarify, according to Pentax DA* sealing is better than WR. I thought a simple way to understand it then is that DA* is "weather-sealed" while WR is "weather-resistant" but their marketing uses those terms interchangeably so who knows how much better they are sealed, and why WR can handle water but not dust....doesn't make a ton of sense to me...

We hear that from time to time, but there's never a clear-cut definition of both. And I would assume a DFA 100 mm WR to be as well sealed as a DA*...

I believe , based on my own personal training field, that the difference simply goes with the tighter manufacturing tolerances associated with DA* lenses. Nothing more.

For the record, even Ned doesn't seem to actually know the difference.

* and WR are samething.

* is used for zooms
WR is used for primes.

Kinda like the da 18-55mm WR kit zoom lens? Or did you mean the da* 55mm prime?

Life's too short to worry about * vs WR

Please have the slightest idea what you are talking about before making definitive statements like this. These types of posts are why there is so much perpetuated misinformation on this subject.

And the 100 macro WR is sealed like the other "WR" lenses, it is not sealed like DA* glass, as the major distinction is that DA* glass is sealed not only for water but also dust according to Pentax marketing, and the 100 macro WR is sealed like the other "WR" lenses. It is helpful to realize "WR" isn't just an acronym, it is a specific designation for a "simplified sealing" by Pentax given to the 100 macro, the 2 kit lenses, and the 18-135, versus DA* all weather sealing. On the boxes DA* lenses show water and dust, while WR lenses only show water, consistent with the vague descriptions.
