[langtitle=sv]First new lens - advice[/langtitle]

Hey all,

Just found the K-5 as a strong candidate when buing a new DLSR. I dont why I haven't noticed Pentax before...

My question, Im looking for a walkaround lens and I can only afford 1 lens with the body for the moment, next step later this year is a fast prime for portait.

Im consider the Pentax 18-135, the Pentax 17-70 or the Sigma 17-70.
Any opinion that can help me in the right direction?

I use the Tamron 18-250 as my walk around lens. Maybe you could have a look at this lens in the store and check it out on the internet . It's a fairly decent lens.

+1 for the 18-250mm. My first lens was the DA18-250mm. Manufactured by Tamron and rebadged Pentax, the Tamron/DA18-250 mm is the most polyvalent and best all-around lens.

While the lens is not longer manufactured, you can find some good copies on the used market (eg PF marketplace, Adorama, Over the last 4 weeks, I saw prices ranging from $350 to $450. The Tamron tends to be listed cheaper than the A18-250m, but both lenses are really about the same.

Are those options any cheaper than a 18-55 & 55-300?

I have the DA 18-250 now and prefer that over the 17-70 that's now boxed waiting to sell

Get the K-5 plus 18-135 kit, it's a better deal than K-5 body plus a handpicked lens on the side.

If you decide against the kit lens (18-55... nothing wrong with it as a choice, BTW), I'd go for the FA 31 limited. In the end, you are going to want a 31 anyway, so you might as well take it to the dance. Like the K-5, it has a learning curve, but after a year of constant use you will understand why it's known as the best of the best.
minus 1 ... how off could you be?

The length you need on the lens depends on your subjects... 18-135 if its going to be mostly people, 18-250 for wildlife + people, 18-55+50-300 for more wildlife.

Keep in mind that how you use the lens is not just the focal length but the conditions under which you plan to use it. The K5 is a weather sealed body, it might be important to have a Weather Resistant (WR) lens for it as well? Depends on the planned or anticipated use of the camera.

If this is your first dslr get a zoom lens that covers a wide range. Over time you will discover what you like to shoot and upgrade as needed while keeping this original zoom as your travel lens.

Pentax 18-135
or an 18-250 lens from tamron or sigma

+1. You want the flexibility of a zoom for a walk-around. I would substitute the 12-24 for the 18-55, though it is expensive.

18-250 is a great starter lens - once you outgrow it - look at 16-50 and 50-135 and eventually 70-200/2.8

if the OP is considering the 18-135, then I guess his budget is around 400-500. he has two alternative, either get a Tammy 28-75 or get the 18-55 and 55-300 combo. the choice depends on what focal length he would need or use more often.

I am going to guess the OP already has a DA 18-55mm WR. Therefore, a good 2nd lens in the zoom arena would be the DA 55-300mm. It is very good optically. None of the big long DA zooms are all that aesthetic in the looks dept, but it is good optically, only slow on the long end but so is the 18-250mm. I have owned the 55-300 (replaced it with a DA* 300) and 17-70mm lenses and currently have the 18-55 WR (my only af zoom at present).
