Tamron 28-75 or DA 17-70?

Pros - 2.8 and the reviews says that it is good, really good.
Con - no Pentax... not that wide. Big chance getting a bad copy??

Pros - good focal lenght, it's a Pentax and has the SDM-motor (I like the quietness).
Cons - "only" f4...

What is your 5 Swedish krona's?

2 alternatives:

- Sigma 17-70mm: Very sharp and wider than the Tammy, very close focus, but slower at the long end.

- Sigma 24-60mm/2.8: A little wider than the Tammy, F2.8 throughout, a bit less at the long end, but a lot cheaper than anything mentioned above.

The Tammy is a very highly regarded lens, with good reason.......just take a look at some of the images produced. It's a little pricey for me so I'm looking for something a little cheaper. I looked at the Tammy 17-50 and Sigma 18-50, but liked the range of the Sigma 24-60mm better, so that will be my next purchase. It'll be a nice fit with the DA*50-135, which I don't mind spending a few more bucks for...

I have the Tammy 28-75 - and it is hands down the best zoom I have ever tried. When I first got it, I compared it to my DA 40, and the Tammy actually seemed sharper at 40mm/wide open.

The range is great for portrats, any kind of people photography, but the wide end is really more like a traditional normal than wide. So, if you want a do-it-all lens, you may want to look elsewhere, but on the other hand, if wide is not so important to you, you could keep the kit lens for that.

Also check the Sigma 17-70, it's faster than the Pentax, a lot cheaper, and has a very good reputation.

Put up with a little noise and take the tamron. The chances of getting a defective one is rare.This is one lens that Iwould never sell.

Agrees with Tammy 28-75 is permanently affixed to one of my K10D bodies. This lens' images are an absolute bargain for the price.

With the Tammy 28-75, never mind the primes--this lens is SHARP! The main reason I continue to keep any primes in the 28-75 range is that they do things that the Tammy doesn't do--the DA35 is a true macro and the A50/1.7 is my low-light lens.

If you find that you need wide only every once in a while, then depending on your budget and/or shooting tastes, you've got several choices, including the DA14, DA21, DA12-24, Sigma 10-20 or Sigma 12-24. You can't go wrong with any of them.

For those of you considering the Sigma 24-60mm f/2.8, Cameta Camera, through Amazon, is offering them at a ridiculously low price: Sigma 24-60mm f/2.8 EX DG IF Aspherical Wide Angle Zoom Lens for Pentax and Samsung SLR Cameras: Camera & Photo

$200 + $13 S&H is almsot illegal

I have the Tammy 28-75mm and love it to bits. It goes from APS-C Normal to Telephoto in one light, compact, crisp package. And at $360 new, it is NOT expensive. Ask the Canikon folks how much they pay for this focal length in their OEM brand.
