About to purchase new lenses - Opinion needed. Thanks!

Iíve been playing around with my new camera Pentax K-X and I think it is time to buy a new pair of lenses. Iíve read some reviews and done some research and narrowed it down to 3 possible choices.

Two of the lenses looks very similar with the exemption that one (ED WR) is weather-resistant but the other is not - SMC PENTAX DA 50-200MM F4-5.6 ED. They both feature Quick-Shift Focus System, but the smc Pentax DA 55-300mm f/4-5.8 ED apparently does not.

I am also a bit confused in the Lens Mount. According to my cameraís ( Pentax K-X )manual, it features the Bayonet mount and some of this lenses use Pentax KAF2 mount.

I am basically looking for an all-purpose pair of lens, mainly for landscapes, indoor and close ups shooting. I am currently leaning towards the 300mm, but the 200mm price makes it more appealing. Then again, I donít know if I should buy the weather-resistant or the regular ones.

Any input will be greatly appreciated.

I just went through the same process. I was leaning toward the DA 60-250 F2.8, but in the end the cost got to me. I picked up a Sigma 120-400 F.4-5.6 that was a couple hundred off, (probably because the one with image Stabilization activated just came out and my camera store had 11 of the old one's left.)

With what I saved over the DA 60-250, I'm getting the DA 18-135 WR. I already have the DA 10-17 so I have 10 mm to 400 mm covered. If I ever have lens money again I can fill in with fast primes.

This is a duplicated thread :-( So, I'll paste my answer from the other one.

The DAL version of lenses (50-200 and 55-300) do not have a lens hood, a distance scale, or quick shift, and have a plastic mount. Only the missing hood you will need to buy is of concern for general photography.

However, the lenses you list are not really the best choices for the uses you list.

Anything over 50mm is probably too long for indoor use. Although you can get great landscape with longer lenses, the majority of them are likely made with lenses around 35mm or even far less. None of those lenses are particularly close-focusing (if you are thinking of flowers or smaller items). For low-light shots, you generally want a lens with a large maximum aperture with an f-number of 2.8 or less.

Oh, and you say you want a pair of lenses, but only list options for one of them. I'd choose the 55-300 over the 50-200.

If I were you I would start off with either the Tamron 28-75 f2.8 (for speed) or Pentax 17-70 f4 (for flexibility) before buying anything else. I don't really know how useful you would find any focal length over 150 for the purposes you list.

The DA55-300 has quickshift, the DA-L55-300 does not have it. WR lenses are more useful on a WR body; if you intend to upgrade (in the foreseeable future) to a WR body, it might be worth it.

Thanks a bunch guys and girls. I've done some more research based in your helpful input and opinions. I think what I really need is something like a Pentax SMCP-DA* 16-50mm f/2.8 ED AL (IF) SDM or the more affordable Pentax 16-45mm f/4.0 SMC PDA ED AL.
