Standard zoom lens for a K100d

G'day All

I own a K100d with the Sigma 18-50mm kit lens. I use the camera for all sorts but mainly when on holidays and hiking taking pics of landscapes and scenery.

I'd like to get another lens that has a little more reach and don't won't to change lenses back and forth, perhaps a 18-125mm or 18-200mm.

- Any suggestions on a good lens better than what I've got ?
- Seeing as though I've had the camera for a couple of years, am I better off flogging it on ebay and buying a brand new camera (pentax, canon or nikon) with a 18-125mm lens ?

Any advice greatly appreciated.

you don't need to change a brand of your camera, smc-pentax DA 18-250mm is the lens you're looking for.

check the marketplace at the bottom of this forum, there might be one or two for sale there..

Either the DA 18-250 f/3.5-6.3 or the basically identical Tamron 18-250, these are probably the best of the breed. As far as I know these are generally preferred to the Sigma superzooms but not sure how differently priced they are in your neck of the woods. (I'm assuming you're in Australia--for whatever reason, that's the only place that everybody seems to have Sigma rather than Pentax kit lenses). I wouldn't necessarily expect these to be dramatically better between 18-55 but should perform similarly to your kit lens in the overlapping range but offer significant additional reach.

If you're basically happy with the K100D I wouldn't sell it. The superzooms available for other brands are not substantially better. If you want to upgrade the body, any of the newer Pentax bodies (K200D, K20D, K10D, K-m/K2000) are nicer but that doesn't take away from the fact that your K100D is still pretty good.

You'll generally get better quality with a multi-lens kit but convenience is the name of the game with the 18-125 or 18-2xx superzooms. For example, you could add a telezoom (DA 50-200 or 55-300) to your existing lens. Either one of these lenses combined with a DA 16-45, DA 17-70, or Sigma 17-70 make for a really good kit. Sigma 70-300 APO is another good telezoom choice. Another reasonably-priced alternative would be to add a designed for film zoom like a FA 28-105 f/3.2-4.5 for the times you don't need wide angle.

The 18-250 would be as good as what you have, and also longer, although it isn't cheap. The 18-125 and 18-200 lenses, while cheaper than the 18-250, would be a step down in image quality from what you have. You'd have to decide if you're willing to sacrifice quality for the convenience of not having to change lenses when you want more reach.

I have the same setup and went for the DA18-250. Haven't taken a lot of shots yet, but happy so far with the choice.

I agree with the recommendation of the 18-250mm: it's a very versatile lens that has given me remarkably good results.

I have a K100D Super as well. My main kit for the last year or so was a 18-55 Kit lens, Quantaray 70-300 (Sigma rebrand) and a A50 1:2. I have since gotten a Tamron 18-250 to replace my two zooms. I couldn't be more happy with my decision. I figure the glass I have now works just fine on my K100D and a couple years down the line when Pentax releases something along the same lines in terms of size and weight of the K100D but with a lot of new features my transition will be quick and relatively painless. That is if you don't count the pain of paying out the cash for a new body

1 more vote from me for the DA18-250. The price has, however, more than double its price now so u might want to consider the Tamron 18-250 as well.
