Swap DA* for Tamron 2.8?

I'm after another lens soon and i was wondering would it be a good idea to sell off my DA* 16-50mm and buy a much cheaper equivalent the Tamron 17-50mm and use the remaining cash to fund the Tamron 70-200mm?

Or Would it be wiser to keep the DA* 16-50mm and just fork out epic loads of money for the DA* 50-135mm which doesn't have as much range as 70-200mm..?

The Tamron is not without their problems. The 17-50/2.8 is known for misalignment and inaccurate AF. The 70-200/2.8 is overall unreliable. I am no fan of SDM, but even less so for any modern Tamron lenses which have great optics but poorly built. I cannot advice what to buy though cos I don't find modern Pentax zooms attractive. I keep Pentax for their primes only.

For what it is worth, I have both the DA* 16-50 and the Tamron 17-50. I bought the Tamron after I had fits with the DA* hunting badly in low light on my K20D.

I shot a whole vacation of landscapes with the Tamron, and found it to be an excellent lens, very nice looking BUT the color rendering is NOT as pleasing as the Pentax DA. The Pentax does something magic with greens and blues, just looks great. The Tamron is fine, just not as good color-wise.

While I can't scientifically prove it, I also want to say my Tamron is a little softer than the Pentax at f2.8 .... again, just a feeling.

I moved up to a K7, and the better autofocus allowed me to return to using the DA full time, especially if I used center point focus only. While you'll never hear me complain about the Tamron (especially at it's nice cost) ... for pure image quality and color rendering, I'm happy to put the DA * back to work.

Keep the D* 16-50mm and buy the Tamron 70-200.

I like mine, too. I don't know what the "color" issue is, especially since you can change colors, and everything else, to suit in PP.

But, after buying the 17-50 you will still need a bunch to get the 70-200.

Yup. If you like the 16-50 the 50-135 will be a treat.

Agreed, colors are in the eye of the beholder and very easy to change in PPing.

I love the Tamron 17-50 2.8, would not trade it even up for the Da 16-50 2.8.
