Hi all,

I will appreciate any advice on my zoom lenses consolidation plan below.

Currently I own the following zoom lenses:
- DA18-55 + DA50-200
- FA20-35 + Tamron 28-75 + F70-210

I am thinking about selling the two DA lenses and get the Sigma 10-20 which is the cheapest of all the ultra wide lenses. (Plus I just got $200 voucher from my friends for my birthday so hopefully I won't need to pay too much extra).

I might also consider getting the Tamron 18-250 if I still got any money left over from my wedding in early Dec. This way, I will have a set of relatively good zoom lenses (not quite the FA* or DA* but probably just a step down) and a good "travel" lens.

What do you think? At one stage I was thinking about getting the Sigma 18-50/2.8 instead but after trying out my Tokina 17mm on MZ-5 today, I think I want an ultra-wide to try out the different views on my dSLR.

PS. I still shoot films on occasions so that's why I still want to keep my compatibility with film bodies.

Thanks
Kenny

Hi Kenny

There are plenty of previous links for you to investigate on these two lenses using the search button at the top of the main Pentaxforums page. You may read about the problem concerning de-centering issues affecting some earlier Sigma 10-20mm lenses, but I believe these have now largely been addressed. Here are just a few of the relevant ones:

P.S. The original room images (in the first link https://www.pentaxforums.com/forums/pentax-slr-lens-discussion/11523-sigma-10...ht=Sigma+10-20 ) were withdrawn shortly after they were posted, to avoid possible problems from the contributor's real-estate clients. Please note that the apparently 'blurred' quality of the two internal photographs of the rooms are NOT the initial images. I copied them from the first post and 'straightened' them out slightly using my photo-editing software before reposting them again. However, doing so made them appear less than wonderful, so go figure.....!!! Read this link:

Whatever you do, don't judge the quality of the Sigma 10-20mm lens from these blurred images, but simply admire the lack of distortion in the wide-angle shots.

P.P.S. Re your comment:

I still shoot films on occasions so that's why I still want to keep my compatibility with film bodies.

A word of caution: You cannot use the Sigma 10-20mm on a film body without suffering from visible vignetting.
The Sigma is designed to work correctly in conjunction with APS-C sensors ONLY !
