10-24 or 18-55WR

I am looking for a wide angle lens and an stuck inbetween the 10-24 Tamron, 10-20 Sigma and the 18-55 WR DAL version. I do have the K-5 and have a 28-75 F2.8 Tammy. the WR lens is my preference as I wanted to have something to shoot in the elements.
Any suggestions?

Just for the record the DA L version isn't WR (the DA one is however).'

SMC Pentax-DA 18-55mm F3.5-5.6 AL WR Reviews - DA Zoom Lenses - Pentax Lens Reviews & Lens Database
SMC Pentax-DA L 18-55mm F3.5-5.6 AL Reviews - DA L Zoom Lenses - Pentax Lens Reviews & Lens Database

I mean there's a huge difference between the quality and field of view of the 10-20/24mm lenses and the 18-55mm kit lens, so I guess it depends on what's more important: weather sealing or image quality and field of view?

As Adam has indicated, you have to decide if you want weather resistance or wide angle. I have the Tamron 10-24 SP and the Pentax 18-55 DA WR and they are both fine lenses.

If you want WR, then the 18-55 is the way to go but 18mm is NOT wide angle. If you want wide angle, then the Tamron 10-24 is the way to go but it is not WR. Even the Pentax 12-24 is not WR.

Only you can decide which feature is more important to you.

18-55 is not wide compared with the other lenses you mentioned there. So, I can't see this being the answer, unless you don't really want an ultra wide.

So you need to decide what angle of view you need first: 10mm is a vastly wide lens - you can stand on the footpath in front of skyscrapers and fit the whole thing in.

There is not much in the way of weather resistant lenses that are also wide. Only the DA* 16-50, but again, not an 'ultra wide', just 'wide' and not cheap either.
I have the 18-55wr and it's OK outdoors in daylight, but when using the flash I really miss having a bit more aperture, as it's often too slow for decent flash photography. It's definitely too slow when teamed with the K7 for high iso shooting. I mainly use it if it's raining or if I just want to pack a small kit. The quick shift focus is a nice feature, though.

I did a few calculations to help with field of view:

28mm = 54.5 degrees (diagonal)
24 = 62
18 = 77
17 = 80.6
16 = 84
15 = 87.7
14 = 91.7
12 = 100.4
10 = 110.5
8 = 122
Hope this helps choosing.

I think that should fill in the gap very well. Also, the IQ should be better than the 18-55 but not quite as good as the 28-75. But since they're both Tamron you'll also get some similarity in the color and image rendering, which should make them a nice kit together.

Why is everybody advising to deceide between either WR of the kitlens or the high IQ and wider view of the 12-24, while the OP can have both?

An old UV or skylight filter, a plastic bag and a tie wrap and you DIY some WR in under 5 seconds for less then a dollar. Or you can get some universal protective sleeves from the fleabay for under 10 dollars.

Personally, after having seen all the threads about failing WR seals and the resulting destroyed gear, I deceided to always use such precautions with my precious gear, even when carrying a fully WR body and lens combination.

WR is a nice feature to have when your camera suddenly get splashed, or when you get cought in the rain. But when actually deliberatly planning on having your gear face the elements, use protection.

I am wondering why no one has mentioned the Pentax DA Fisheye 10-17. I have this lens, and like it a lot. I can stand about 10 feet in front of my house and capture the entire structure at 10 mm, and it is great for major architecture--cathedrals, downtown buildings, etc.
