Sometimes is helps to look at hard facts and measurements.
Why don't you have a look at the following reviews:

Tamron Lens: Zooms - Tamron 28-300mm f/3.5-6.3 XR Di AF (Tested) -!

Construction Quality --- Image Quality --- Overall Rating

6.20 --------------------------- 6.20 ----------------- 6.60

Tamron Lens: Zooms - Tamron 18-250mm f/3.5-6.3 Di II LD Aspherical IF Macro AF (Tested) -!

Construction Quality --- Image Quality --- Overall Rating

7.40 --------------------------- 8.20 ----------------- 8.20

Perhaps this works for you. It does for me.

Thanks for the links..
That test that was done in this review of the 28-300mm tamron is what I too have found...This is why I was hesitant to purchase the 18-250mm lens and instead choose the 28-75 F2.8 that I am very, very happy with...
Like most folks here, I don't mind spending my hard earned bucks on lenses or a lense, but we do want to get what we pay for if not more... I for one will spend the $500.00 bucks on that Tamron Lens today, but if it does not meet expectations then I will for the first time return something...I have some 12 lenses now and this is getting expensive.

By chance and determination I got what likely was the first 18-250 for PTX in the US. Except for special shooting needs it is rarely off my K100D since getting it in March. I am no pro but this lens suits all my needs and produces results that satisfy my and my audiences. I went to the PhotoPlus show in NY on 10/18 and looked at and treind the PTX version. It seemed identical to the Tamron though maybe a little smaller. The PTX product manager did not deny it was a Tamron-made lens but emphasized the PTX coatings...........cost me $40 to find that out. PTX folks were lonely - Nikon was mobbed. PTX did say something BIG is on the way....

matix, thanks for the heads up on "Kamera_store". I hadn't spotted him on eBay before.

Russ, your 18-250 set on flickr has convinced this "lurking" lens hunter to get one.

Just got mine today and I am impressed...The speed of the lens was a bonus as I was not expecting that...The sharpness at both ends is pretty darn good...
I have it on my K110D (no shake reductionz) and the pics come out sharp with NO motion blurr, good colors, I am trully amazed....

I also have the same lens on order from Pentax, but I think I am going to request a refund as I do not see how the pentax version will be better..

Hi jgredline
Here's what a forum member had to say about the Tamron 28-300mm he was selling......hope this summation may help ?
"Tamron 28-300mm f/3.5-6.3: Now $80 (was asking $100) shipped to US 48
This was an impulse buy. I had looked at several "superzooms" and wasn't impressed. I then saw this used in "EX" condition at KEH for around $120 total shipped. Most people said both this older circa-1999 model 185D full frame and the 25% smaller circa-2001 newer A06 full frame were better than the latest APS-C sized circa-2005 version, so I figured I'd try it. I then did some "test shots" of a letter with print on it from about 20' away with the DA 18-55, AF 28-105, DA 50-200 and this Tamron 28-300mm at 50mm, 100mm and 200mm (sans the DA 18-55 at 100/200 and the AF 28-105 at 200, obviously). No comparison, the text was barely legible with the Tamron 28-300mm. I guess that's why I hate superzooms, including this 10.7x. But you may not. The most I'll ever go with personally is the Sigma 18-125 (6.9x), and I probably won't even get that until I hand down my K100D to my wife. I'd rather just change lenses. Again, you may not want to".
Best regards
That was me BTW.

I'm still trying to sell this lens if anyone wants it for $80.
It's fine for resizing down to LCD monitors (e.g., 1280x1024) and you won't notice the IQ on even a high-res photo frame (800x480).
But if you want to print at the native 6MP or 10MP K100D or K10D, respectively, look elsewhere if there is any fine detail at the pixel level (like my "text" test shots).

I was previously going to buy the Sigma 18-125 for my wife when I handed my K100D down to her (when I upgrade to Pentax's next camera).
But now I think I'm going to just get her this 18-250 lens, especially if it's sub-$300 after rebate mid-next year.
Especially if everyone agrees the IQ is good for this level of superzoom.
