What does the AL stand for in the lenses? I've seen WR for water resistant, but never AL. Also, what is the designation for water and dust resistance?

Found online, hope it helps...ED = extra-low dispersion glass elements, reducing chromatic abberation. Not reducing the price of the lens, unfortunately.AL = aspherical elements, used in wide angle lenses to get a flatter focus field and better corner/edge sharpness. Like ED, it costs more.IF = internal focusing. Only glass elements inside the lens moves when you focus, the rear and front elements keep in place. The lens keeps the same size at all focusing distances. A bit more complicated for the engineers, thus adds to the price of the lens.

My best guess is "automatic lens" to distinguish them from lenses without automatic focus or aperture, which the K-30 can also use.BG

I have a Pentax older that yours and all of the lens seem to work fine. I have both Sigma and Tamron lenses You know that with the older lenses it won't be weather resistant. It's only WR with Pentax WR lenses.

I erroniouslly purchased the non coated version for my wife. She is a sunrise/sunset photographer. The non coated version allowed significant lense flare when pointed into the sun. While on vacation, we met another photographer who had the coated UVA filter. She had the same problem we did, only bought the MRC and hasn't had a problem since. I have since purchased a B+W UVA MRC filter for her, among other stupidly expensive filters, but I have wasted enough money buying items "on the cheap" for her hobby to know that you get what you pay for. I buy B+W exclusively for her 5D Mk ii and L series lenses.

The kit lens in 18mm-55mm is not weather resistant but the kit lens in 18mm-135mm with WR suffix is weather resistant.

the only lens for this camera that is not water resistant is the DA L. if there is no "L" you can order the lens or pkg and know that it is water resistant, even if it doesn't have the "WR" on the lens. this i asked pentax (you can call). i lost money ordering the one with the "WR" from another company. i did not have to do this. :( hope this helps.

I don't believe I've ever gotten any unless I'm specifically trying to get them. I suppose if you have the hood off it would be more susceptible, but why would you? The FOV is narrow and the hood is pretty long, especially if you use the APS-C adaptor. Hard for strong light to hit the lens without aiming nearly right at it. I love this lens, it is my flagship lens. Excellent for sports photography.

Mine just say JAPAN OPTICS. They do not seem to be multi-coated. I use the polarized filter to protect the lens, and it does a fine job of that at a low price. I would recommend a more expensive single filter for more serious work.

the body is weather sealed and very well, even without wr lenses i have been out in sub zero temps and rain and had 0 issues at all, but i wouldnt change lenses in the pouring rain

They are machine screws. They come in and out but are tight and don't let water in. What the screws do is they hold the black seal onto the housing. In other words they hold on the lense. This was considered old now because the standard housing has the same exact screws just on the inside. Get this housing it's awesome. Your case( if you look on inside) you should see screws. It's the same on this just on the outside to attach or hold on the lense. If you have any more questions feel free to ask

It is "water resistant" when used with a water resistant lens. Older lens probably won't give much protection. I think if it a a safeguard if I get caught in the rain.

Have had the lens for a while now....It's been in some pretty dusty places - Including a few National Parks as well as the Beach. Never really experienced the "Dust Problem." Great little lens that delivers beautiful photos. Great walkabout lens for my 60D. Saving for the 70D as we speak.

Mine did not. It came with an 18-55 mm AL lens. Pentax has announced two new WR (water-resistant) lenses: the 18-55m WR and the 60-200mm WR.

T2i isn't dustproof either... If your worried about serious amounts of dust, you should buy L lenses and a XXD or XD frame (e.g. 30D frame, 5D frame, etc). If you can't afford a weather resistant frame, you probably shouldn't worry about getting weather resistant glass...

When I purchased this I read in all the reviews the body is WR but the lens is not. I don't understand why they sell the lens with the camera when it is not WR. But it was not a issue for me personally .

The K-5 II (and designated Weatherproof) lens are designed to handle average dust, rain, humidity, and the occasional splash. The manual does recommend that the camera be dried and cleaned as soon as possible when exposed to these extreme conditions. Otherwise I have to agree with the prior answer, if you are planning to be exposed to the elements for a prolonged period of time, an appropriate housing or weather shield is still a good idea. For more extreme conditions where water exposure is a guarantee, I would recommend one of the Pentax / Ricoh Optio line of cameras such as the WG-3. Those cameras are water sealed and better suited to handling an under water experience.

Yes, the lens that comes with the AW1 is weatherproof. Other Nikon 1 lenses also work with the AW1, but are not weatherproof.
