Im presuming there has been some extra processing in there but even so, I really like them.
Nicely done.

Thanks for the comment Mike. The second photo has minimal processing. The first was taken near dusk and has contrast, exposure upped. Also some extra saturation to show vegetation and beach sand colour. Clouds are courtesy of nature.

Hi Guys

It's my first post here - been lurking for a while and building my kit up. I was lucky enough to get the Sigma 10-20 as a Christmas present for my K100d and have been testing it for the last couple of days. I'll try to link a few examples through photbucket below. I've read that a lot of the lenses have had softness issues and i'm worried I have a duff one but too inexperienced to see it! What do you guys think?

Thanks for any advice/comments

Owen

They do look a bit soft, but can't be sure from those reduced-size pictures. It would help to post some crops at full size and state the settings. Preferably post a good example from another one of your lenses too for comparison to eleiminate any issues with software, etc.

Focusing can be tricky with this lens, so take several attempts to focus a test shot (select the best from a batch) before suspecting that the lens is faulty.

Time for a brick wall and a tripod I think

For me that always seems like a good test as you have a flat surface with lots of texture if you get the right light and you really ought be able to get a good focus too.

Boring but helpful and the tripod will eliminate any camera shake which again with this quite large lens I have found to be an issue. If you haven't got a tripod just stand the camera on a chair and use the self timer.

The last shot suggests it's OK to me.
