Default Raplacement Kit Lens - 16-45/4 or 20-40/2.8

Looking for something to replace my kit lens... Mainly debating between the Pentax 16-45/4 and the Sigma 20-40/2.8. (I also thought about the Sigma 28-70/2.8, but really want to keep the wider range available). They can be had for about the same price, so I was wondering what everyone's thoughts were on each. Also, how's the distortion on the 16-45 at the wide end... does it get fishy at all?

Any input would be greatly appreciated!

dont have any experiance with these lenses but for me my eventual intension is to replace the kit lens with the DA* 16-50mm - its kinda pricy so wont be happening soon but hopefully should be worth it in the long run

Seeing as how I picked up a K20d with faulty SDM (it was DIRT cheap!), I don't see myself spending that kind of money and not being able to use it to it's full potential.

What's your motivation for replacing the kit lens? i.e. need for speed, additional zoom, wider angle, LBA, etc? If it is speed/ low light shootiing, I'd definitely get a f/2.8. (Sigma 18-50 f/2.8 is $419 @ B&H). If it is a wider shooting angle, the 16-45 or even a 12-24 f/4 would work. If your answer is LBA, then get them both .

lol yeah that sounds about right!

On a more serious note if the contact points for sdm lenses are broken on your k20 why not see about getting it fixed? then you bring back the DA* back into the equation - its wide its fast and its weather sealed

...because I have no need for SDM and the price of the slightly damaged K20D was the only reason I was allowed to upgrade from my K100D, I lived without SDM on the K100D, so I told the wife I wouldn't spend anything more on the K20D than I could sell my K100D for and she agreed.

Plus, What I plan on using this lens for doesn't need to be extremely quick or silent focusing, so why spend the extra? I think I am going to pick up the 20-40/2.8 for now then save up for a 10-17 or 12-24 for shots that need an extra-wide lens. We'll just have to see.

The only problem with your plan is that when you get either the 10-17 or the 12-24, you'll decide you also want the other one. I debated over these two lenses and got the 12-24. Love it, use it all the time, it's a real workhorse, wouldnt be without it. But it didn't satisfy my creative urges as much, so now I have both lenses (and am a much happier camper). Good luck deciding which one to get.

Inneyeseakay... what did you ever do about this lens decision? Willoughby's Camera in NYC has the Pentax 16-45mm lens brand-new with warranty for $304.99 as of this date. That's about $100 less than you'll find it most other places these days:

Here is a shot using the 16-45mm Pentax lens and I don't find it too fishy at all, although I hear that there are some quality of the image issues with some versions of the lens.

I have the Pentax 16-45...use it as a standard lens on both my K10D and KM (K2000). I have taken 1000's of photos with this lens and I'm very happy with it. I take a lot of closeups of vintage cars.....very close up...using 16-18 mm settings...distortion in my eyes seems ok and the len's pictures are crisp, very clear.
