For the people who bought one of these three lens as a replacement to the kit lens, how noticeable was the improvement in IQ?

the kitlens would be eating dust.

Thanks. I kind of figured IQ is much better. I'm just not seeing pictures on the web which make the purchase as easy as it was for the Sigma 10-20 or the DFA-100WR. However, Tommot1965's pictures look quite nice.

I had mentioned this before with the improvement in IQ of the zooms, there will be a time where I would limit myself having an all-zoom setup. well, probably keep 1 fast prime and buy a telephoto macro.

my setup would probably be a 12-24, 24-70, and 70-200. if not, a 17-50 and 70-200. then buy either buy FA31 or keep the A50/1.2 + a 150mm macro. trading my current line-up would not cost me anything and still have some extras to buy a new body and an X100. yummy.

Dan - just go through The Tammy Club thread. It is a very long thread but choc full of great shots, the majority of which seem to have been shot with the 17-50 ! The *16-50 has it's very own thread - also full of beautiful shots. The Sigma is very new so it's more difficult to find shots but every test indicates extreme sharpness - it's basically a case of cost and whether or not you require SDM/HSM (as the Tamron doesn't have it for Pentax).

Personally for me it came down to the Sigma or the Tamron as I couldn't justify paying the extra for the Pentax since I didn't see any advantage over the others, either in the lense functions itself or the quality of the output. Since the Sigma wasn't in stock here I bought the Tamron and am very happy so far, this was my first time using it : https://www.pentaxforums.com/forums/post-your-photos/126657-landscape-sunset-...west-lake.html

If it works out then great, if it doesn't I'll get the Sigma, but I'm happy so far, it is a very sharp lense with excellent colours and rendering. No matter which of the three you buy I think you would be very pleased with the major leap in quality.

I love my Tamron 17-50- great lens. That said, the bokeh is hit and miss for me. Point light sources sometimes (not always) have a ringed 3-D effect:

the OS works great..better than the SR I feel. easy hand-held at 50 mm 1/15 no shake....HSM is noise free, you can hardly hear it..and its so fast its almost instant focusing it takes about 1.5 secs from macro to Infinity and back again.....its by far the best lens ive had yet...mind you ive not had many...LOL
I'm wondering if you have had a chance to test this lens in low light AF conditions? I've run into some situation where my Sigma 10-20 on a K-x has had trouble locking in on a focus point.

I have no problems ...although anything under 4 EV and the K5 doesn't focus too well through the VF...but all my shots using LV have been great...so no problems with the lens

And just another one. This is the boat I took to an off shore island at Hong Kong.
Main complain about the 17-50 is the weight, but seriously it is making my FA43 look shy. Luckily the FA43 maintains its pride with the colour, weight and a little special magic it could take.

Nice shots Hide ... suggest you put them in The Tammy Club thread (I double checked JT - definitely a Tamron this time) ! Also maybe crop or clone bottom right of that very nice Chinese junk shot.

Mr Frogfish is correct, these are nice images & it would be great if you could post them here: https://www.pentaxforums.com/forums/pentax-slr-lens-discussion/31955-tammy-cl...ml#post1322486

Hey Hide, The Tamron 17-50mm f2.8 is light actually= 440 grams. The Da 16-50 f2.8 w hood is 600 grams. It surely is not fair to compare the weight of 1 prime, to the whole 17-50mm range. Try instead comparing the weight of 4 primes: say a 15mm, a 24mm, 35mm & a 50mm to the weight of the Tammy.
