Tamron 70-300mm DI f/4-5.6

So I'm quite happy for now, until I can save up for a k20d down the road, with my spunky little k100d. I have a storied Pentax 50mm M f/1.4, a 28 mm f/2.8 and the kit lens, as well as a bunch of other old k1000 lenses that aren't of any great renown.

The one thing I am lacking is a decent telephoto. Unfortunately I cannot afford a decent telephoto.

So in the spirit of compromise I was looking at this Tamron 70-300mm DI f/4-5.6:
Tamron 70-300mm 1:2 F/4-5.6 DI LD Macro FS=62 For Pentax AF |, The Internet's Digital Superstore

I know it's not top of the line, but I really don't have the cash to spend on something question is, is this good enough for amateur shooting, or is it cash thrown away?

Also, and suggestions for something else as an alternative in the sub-$200 range?

Sub $200 .... that is your choice.

If you can afford just a bit more.... go with the Sigma 70-300 APO

I just went with the Sigma (I was in the same debate as you) and I think I chose correctly.

Keep your eyes out for a used one (That is what I did) and you can certainly save some bucks.

I am finding the sellers here on this forum to be very stand up and honest.

I went on the reccomendation of other photographers...

Do a search here on the forums I think you will find lots of comparisons as well as do a google search.

See if you can go to a camera store and try both.

I think in the end the choice will have to be yours.

I have the Tamron and use it with the Tamron 1.4 x tc. My copy is very sharp and has very very rarely had purple fringing. I posted many shots with this lens a while ago on dpreview to show just how good mine is. However there are many reports of copies with lots of purple fringing so it is a risk you take. I paid half of what the Sigma goes for.

IMHO, Tony got an unusual Tamron. Most will have PF (I even sent mine back to Tamron to check it and they said it was normal).
It is sharper than the Sigma though and the PF is mostly fixable in Helicon Filter (though it does cause some side effects when you fix it that way)...

Check out used lenses. I have Sigma 70-300mm DL version that I have bought used for $60 (or $80 I do not remember). I love this lens. Sure it is bigger than DA lens and AF is not that fast but the image quality is very good.

I have a Pentax FA 80-320mm. Pictures are very sharp and colors look very good. You can get a used one for $100-150.

I posted some shots with the FA 80-320mm and my K100D here >
