K-5 vs K-30 which is more weather resistant?

I'm looking to purchase my first DSLR. I plan to take a lot of outdoor photos occasionally in inclement weather. I'm considering both the K-5 and the K-30. Which is more weather resistant? The K-30 is advertised as weather resistant but I have read that the K-5 is also very weather resistant even if Pentax didn't advertise it. If they are the same level I'd rather go with the K-5 because of the better feature set. Thanks for your replies!

The nature of the sealing is the exact same.

However, the sealing in DA* lenses is superior to that of DA WR lenses.

You won't be sorry with the K-5. The thing's built like a tank.

The K-30 advertising campaigns have been a bit more aggressive with regards to weather resistance. But Pentax has always advertised the K-5 as also being weather resistant. On their webpage, they used to show the K-5 completely wet, as if in the rain.

It seems there are so many lenses on Amazon, is there a chart that shows the level of weather resistivity for the different abbreviations: DA, DA-L, DA, IF, AL, ED, DC, WR, etc. ?

If the lens is a DA* (vs DA, D FA, DA L, etc), then it's got slightly better sealing. The specs for the weather sealing aren't posted anywhere.

If you're curious about the different Pentax lens series, you can read about them here and here:

To add to what Adam said, and the excellent links he provided, the lens must either be a DA* series, or have a WR suffix in the lens designation, to be considered weather resistant. Some lenses are available in WR and non-WR variants.

I have got my K-7, then K-5, and now K-5IIs, mindbogglingly drenched in rain several times over the last 4 years. (In each case with a DA* lens). They have always carried on working without problems. (So far!) But I wouldn't change lenses in rain!

I find the K-7, K-30, K-5 and K-5 IIs all interchangeable when it comes to weather sealing, and I would bet quite a bit the K-50 would be just as sealed. I would be comfortable using any of them in the following experiences:

The DA* are a little pricey for me. Can I expect good results from the DA WR lenses in drizzle or snow?

Also does it make sense to get a single 18-135mm WR lens in place of two lenses, the 18-55mm WR and 55-200mm WR? Does the 18-135mm WR perform better than the 18-55mm WR in it's zoom range?

Way better....it's edge sharpness in the 70-135 range that holds it back in the ratings and even then, it still has excellent center sharpness, just rated on it's performance from 18-50 it's got everything the DA* 16-150 has except the 16 and the ƒ 2.8. I haven't willingly put an 18-55 on the camera since I got the 18-135...as for the 55-200, I don't know, but I don't see how you replace the 135 -200 thing. Although if you think of it that way.. 135 APS-c is 200 FF. That lens (the 50-200) just doesn't have much of a reputation around here. Given that the forum rating for sharpness is 6.6 and an overall rating of 7 something...no one ever gives a lens a rating under 5, so you can effectively subtract 5 from that score and rate it out of 5... so say 1.6 out of 5 for sharpness.. ouch. The 18-135 is probably just as good if you blow the images up to the size of the 50-200 images shot at 200mm, but I'd ask someone who has both if I wanted to be absolutely certain.

Anyone have both?

I would recommend the 18-135 over the 18-55+50-200 combo. I have both, and my 18-135 is equal or better than both at all overlapping focal lengths. My 50-200 is strongest at the ends, about equal with the 18-135 at 50mm, but a lot worse at 135mm.

I will gladly give up the 135-200 range for the flexibility of not having to change lenses in bad weather.

Thank you for the great input. I plan on starting out with a K-30 and likely the 18-135 for most foray into DSLR cameras. Do you ever feel limited in not having the extra 135-200 range? I plan to take a mostly family photos and landscape photos both in sunlight and low light.

The only times I feel the need for anything longer than 135mm is when I'm shooting wildlife, but I have a DA 55-300 for that, and it's better than the 50-200 anyway. Should you wish for anything longer than 135, that's the one I would recommend. There is sadly no WR version of it, though.

For more general use 18-135 should cover most of your needs.

For low light you should consider a faster prime in addition. The DA L 35mm f/2.4 is a good and affordable allrounder.

But start out with the 18-135 (or 18-55) first and see if it does the job, or if you feel limited in any way.

Thanks for your advice. Can I still expect reasonable low light performance from the 18-135mm?

I quick question on a separate topic; does the K-30 work with a remote for controlling the shutter button?
