Here's a 3 part "review" of this lens. I initially got a bad copy (misaligned or decentered lens), returned it  and received a good working copy. The text is copy and pasted from our Facebook page but I couldn't attach the images so I'm including the direct links to the album. Check each image for a more detailed description of the image, settings and issues:




I just picked up the "new" sigma 18-250 OS Macro as a walk-around lens and wanted to share some of the test shots. The over all impression I have from my limited time with it is that Sigma has put together a decent... not awesome... a decent general snaphooter. Great range in focal lengths, lightweight, amazing OS, a few sweet spots of sharpness and versatile. For under $300 (keep your eyes open for sales on eBay!) it might be one of the better do-it-all lenses for casual snaphots. All shots were taken in Jpeg Fine, resized to 1000px and "saved for web" in Photoshop CS6. No post processing in any shot

Ut-oh, problems spotted!:

I did some further testing of the Sigma 18-250mm OS Macro lens and determined that I received a bad (defective) copy. Something about the softness in the wider angle shots wasn't well sitting with me so I decided to run a few extra tests to see if i was being picky or I was truly seeing an issue with softness in the lens. Read through the descriptions of each images and I'll explain what I found but my guess is that there's a misaligned lens element in one of the groups. Telephoto shots are wonderful, macro shots even better, but anything less than 135mm was mushy, ghosted and full of chromatic aberrations.

Ah, a good copy:

So you may recall that I ordered a Sigma 18-250mm OS Macro lens last week and after a few test shots determined either the lens was just plain terrible or I got a bad copy. A bunch of research lead me to believe the first copy had a misaligned lens element so I took a swing returned the first copy and ordered another. 

The results from this batch confirm that the first copy was indeed defective. While the lens is a "walk-around super-zoom" and not going to produce the highest quality images you can clearly see that this copy is MUCH better than the first. Images resolve to acceptable sharpness, there's minimal distortion and none of that ghosting I saw in the original version. My initial assessment still stands; the macro functionality is actually impressive, focal lengths above 70mm are really pretty nice but under 35mm are still a little "weak". Not horrible, it's just that the deeper zooms are much better. Again all images are jpgs straight from the camera, resized to 800x600 in Photoshop and saved at web quality. No post processing other than to provide the 100% crops.

With that I can comfortably recommend this lens as a walk around snap shooter. It does the job nicely...as long as you get a good copy.

I also own the lens and think Very highly of it. Zoom have come a long ways as far as image quality, even the super zooms. But for the best you will need primes. Although I do have a Tamron 70-200 2.8 that continually surprises me for the tack sharp shots it delivers, Bob

been thinking of getting this. I'll check out your pictures later.
