There have been various threads both here and on other forums about Sigma lenses breaking, either the zoom mech of the AF. To be fair to Sigma, it has also been said that they have repaired the lens at reasonable cost. Then there was the case of a certain lens having to be returned to Sigma for the mount to be changed as it wouldn't fit the K1. Add to that the threads about incorrect exif data because Sigma back engineer their lenses rather than pay royalties. I may well have missed them but I have not seen such threads from any of the other after market lens producers.

So to go back to the original post quoted "might be good optically but very poor mechanically. [/quote]I don't get it, we as pentax users should know better than to believe everything that's posted on forums, if we wanted to we could find posts and threads about failures and breakages and quality control in our own brand , in canikon, samyang, tokina , oly, pano, so knee
And every other marque out there, I have had and used many sigma lenses, didn't like all the ones I've tried, but that's down to my preferences, others I've absolutely loved. I'm sure there's been some that have broken, but I've never had one break or fail on me.

So to see someone completely write off a brand, prompted the question on what He was basing his rating on.


Ah I see Haris has already made this point anyway

Nice way to start the year Gareth.
3 and 5 for me.
Sweet shooting.

Sigma 105mm macro lens is af, and can be bought quite cheaply, just because it has af, doesnt mean you have to use it.
Its the macro lens I use, and I use it with bellows and ext tubes.
Cracking lens.
You'll probably see some sample shots on my posts.
Plenty of other 100mm options and 90mm

Yep, I've seen dafs are up already too, same as last year.
Nice shots btw.

Certainly seems to be performing well judging by those sample shots.
If you don't like it, let me know

What do you base that on,
Plenty of us happily using sigma on here.
No better or worse than any other brand.

Pm sent

A little bump, and open to offers.

Cheers Bill, Much appreciated.

Here's a link to some unedited shots, only jpegs but should be good enough to get a flavour of what you'd do with them.

Cheers Haris, I thought it was poignant enough to warrant sharing.
I might make another trip now I know the story. Weather was against me that day, just to see if I can get a fitting shot of it. Not that it really matters, but I'd like to try.
