New Sigma 18-250 Macro or old Sigma 18-250 OS HSM

I'm wondering which would be the better of the two lenses the 18-250 Macro or the older 18-250 OS HSM lens ??

I can't attest to which is better or worse, but you can see the photos I've taken with the new lens in the photo archive here: https://www.pentaxforums.com/forums/lens-sample-photo-archive/231056-sigma-18...ns-sample.html

There are even more samples (some taken this weekend) on my flickr (over 100 photos in the set): Sigma 18-250 HSM DC Macro - a set on Flickr

I ordered the 18-250 non Macro OS HSM but when I got the order I received the 18-250 Macro non OS version of the lens I actually wanted the OS non Macro version because I have had very good results with my 150-500 lens. I read many reviews and even here on the Pentax site the non macro version rated slightly better. I am going to keep the newer version because got it from Amazon for the older lens price. I am curious if anyone is using the older verion here on the site and what their thoughts might be also would be interested in B & H's thoughts.

I've heard that the newer version is better optically though I can't confirm. While OS might be better than the built-in IS of the Pentax camera, the trade off is battery life. I heard that Sigma stopped putting the OS in the Sony and Pentax version of the lens because of the the in-camera IS. I find the macro very useful (though it's not really macro, but more like close focus). It does help being able to zoom in close to a subject. I've only had a few times where I wanted to get closer and the lens wasn't able to focus close enough and I had to back off a bit.

According to what I have read the barrel distortion is a little worse on the newer version and from close attention to reviews the newer Macro version is better in image sharpness. So far I have no complaints other than the fact that I ordered 72mm filters for the non macro version I ordered but I do have a 400mm prime sigma lens that I can use the filters with, the 400mm lens is used much less than the 18-250 probably ever will. Thanks for your input I appreciate it very much. Still wondering what other users of the two 18-250 lens thoughts are ? Battery life is something to consider but I shoot with my K5 & K7 and always have a battery grip on the camera and so far I have never run out of power on a shoot.

I correct for barrel distortion in Lightroom. It does make a big difference in the outcome of the photos. You can really see the distortion in the before and afters but if you have the appropriate software, it's a non-issue.

I use Elements 11 not sure if I can fix barrel distortion with that program will probably need to buy more software. although for the time being I do little PP.

I used a canon macro version. The 250mm sharpness is really good. Although I feel some photos are not as natural as taken with other canon lenses.
