Testing my new Sigma 18-35mm f1.8

[dulceza]

Hello everyone,
As promise, here are few shots at apt 1.8. The lens performed well in good light condition but at night I had this vignetting probably as all wide aperture lenses used with wide open apertures (??) . Overall I'm pleased , however the lens hood is mandatory to prevent glare and in low light is the vignetting that's curbing my enthusiasm.
Please let me know what you think.

Sunlight

Worked very well for Sunlight.

Hi, Dora

That vignetting just goes with the territory, and if you are otherwise happy with the results, look no further. I just shoot a little wider than needed, an crop the vignette.

Nice captures. The one of the doggy looks a little soft.

Hi Dora,
Are you sure it is vignetting and not the lens hood? To me it looks to serious to be vignetting.

Hi Dora,

Well it's not physical vignetting or it'd be all 4 corners. It's possibly but unlikely, internal vignetting. That can be seen strongly on 2 corners but would also seem tae "creep" up the sides.

Ah tend tae agree with Andre, looks tae me like the hood is incorrectly fitted, obvious though it may seem. Doesn't it come with a default hood? Vignetting that bad would be obvious in bright sun as well. Looks like the two long edges of the hood. That Sigma has an excellent rep for anti-vignetting. Remember reading an interview with the designer where he was very proud of that fact.

Hi Dora

i agree with most of the comments about the lens hood causing the problem,is it the petal type that has 2 sides longer than the other? if so there's a good chance its on the wrong way.

I remember a joke about someone complaining about pain between eyebrows when drinking tea and the doctor asks: have you tried to remove the teaspoon? True, is a petal type but I think it was fitted correctly (should I remove it in low light?) at 23mm I don't have the black corners. Tomorrow I'll go back to the store and see what's wrong. I wish it was just the hood.
Thank you all for your input
Actually it is the hood, I tested now and it seems a little bit loose

Problem solved?
Now try shooting with in camera flash and a longish zoom having a hood on.

Yes, solved, silly me , I followed the instructions from the brochure
Thank you
