nice... :)

i was thinking about this one as a replacement for my 18-55 as it gives a longer reach, but is also relatively light.

can share where u got it from and est. damage?

Ya I got this to replace my 18-55m kit lens also. Like the focal length and its not bulky. Not so much distortion like 18-200mm / 18-250mm / 18-270mm. Got this from a friend, a good condition should be SGD300 or below.
But now I have problem, poison by the DA*16-50 F2.8.... Struggle not to sell this and save for the DA* :D
If few weeks later you see I post in B&S section, you know why lol!;p;p

At longest length, 125mm. Consider ok right? Btw this photo have done brightening, think I stopped down too much (F/10).



And dont know why in Photoshop it read me exif info lens as PENTAX-F 28-80mm F3.5-4.5 instead of Sigma 18-125mm. Also to check with you guys, how can I enable the exif in flicker, I mean i can view the exif in flickr page, but when I insert the picture here it can read only the copyright... Any advice? Or maybe I need the paid account to enable this.

The starburst effect is inherited from the aperture blade design on the lens.

Thanks for viewing, overall this lens is quite sharp to me, Im not a pro, just the interest in photography.
