sigma 15-30mm EX DG f3.5-4.5

hi, about this superwide zoom, many people do not get any vignetting but some on the internet commented they had.

what are your experiences?

internet price $800, i heard fotoguide is $1050 or so.

only uses gel filters, so that's it, no circular polariser?

With an S1, I experience vignetting at 15mm end when use with the hood (which also act as a lens cap). else no prob.

Take the lens cap off and the problem will ceased to exist..

Using it on my ex-EOS300 and D30.. no pro so far!

hmm...looking for super wide angle for my eos33 this lens sounds interesting.

kailord: what do u mean by internet price? assume we're talking about 1st hand lenses here?

[Klause]

Hmm seems like 15-30 is a good lens. Ultra wide.. got anyone with sample pic of it being used for 15mm ?

another one..with picture comparisons!

Dunno about using it on a DSLR but with film, the 15-30 I used gave me "smeared" edges and corners till f/8-f/10. It was as if the different parts of the image were pulled disproportionately. Looked like spherical aberration. I shot some frames using the Canon 15/2.8 fisheye just to compare, and the difference was incredible. The centre 50-60% of the image looked good, so it may not be a problem for DSLR users.

I am not sure about the colour balance on all lenses, but the sample I tried was extremely warm, though the colours were very saturated. One problem was flare... quite bad.

Bear in mind, this is only ONE sample of the lens - the one I tried. You might have better luck. I am not too confident about Sigma's QC.

Let me see if I can find the slides I shot with this lens. Will put up some scans if I find them.

oh,.... there is so many thing you don't know abt mi....
so I'm not really suprised.

Keep trying harder dude!

using D30 no count leh, the 1.6 FLM...
problems with the sigma15-30 lies around the edges/corners and there are quite a few reports floating around the internet that mentions these... they also agree that stopping down to f/8+ is the way to correct them. that might be a small price to pay for versatility.

can take off hood one meh?

apparently u can get flare quite easily and even bright light within the frame itself can give rise to further flaring as well.

today alan photo quoted me $1000 for 1 piece of sigma15-30, i asked how much if 3 pieces, he said $990.
FG quoted $1030 for 1 piece.

I'm pretty interested in buying this lens for my D60. Anyone else also?

new?? 2 weeks ago i ask was $1150 leh...

may be $890 for used?

[StreetShooter]

No, boxed and new. That was the asking price. I wanted to trade in two lenses for it and top up the difference, but in the end I changed my mind.

[Bluestrike]

grey market?

green market, blue market, as long as got warranty, looks new, sure can bluff me one.

TCW ah.. ok will check it out, thanks Doc.
