Sigma 14mm, anyone?

Has anyone tried that lens UW on a digital camera? I'm looking for something that would be similar to a 20 mm lens on a 35 mm camera - fairly wide, fast and rectilinear. What are the options?

cheers

fast and rectalinear

sounds like a good nite out for those peculiar boys

My experience has more to do with the Nikon 14mm, very nice coverage, similar to what i had in film with the 20mm Nikkor, if the Sigma is half the Nikkor it will still be a great lens, throw in a Magic Filter in the rear filter slot and you have an awesome combo, I did some really cool shot of wreck and shark with this combination (Nikkor 14mm & filter).

Christian,

Ken Kneznick from Island Dreams in Texas has used this lens very effectively underwater, plus I know Doug Perrine and I think Jim Watt has, too.

It's VERY wide, and does tend to flare a bit. But if you don't shoot into the sun as much it is nice and sharp.

At MUCH less than the Nikon as Jean states....

Good luck!

Thank's guys. Sounds promising. I have noticed the Nikon, but it is a bit costy compared to the Sigma and if it doesn't perform significantly better the Sigma seems to be a good buy.

Ooops, a small misspelling there I see. Foreign people can be fun

Do you know if there are any differences in optical quality on the Sigma and the Nikon?

"Do you know if there are any differences in optical quality on the Sigma and the Nikon?"

I've used Nikon 15mm MF lens and Sigma 14mm MF Lenses underwater and doubt that you'd see any optical difference between these two (the Nikon flared more though). So assuming both companies have progressed designs I don't see that the Sigma will be noticably different for the vast majority of uses. On a cropped sensor the Sigma should be great - however you will need to be sure that a port is available for your housing which will properly align with it, as you will find corner blur/streakiness if you get this wrong.

If you're shooting it on a cropped sensor camera make your own lens hood and mount it on the lens. This will help to cut down on the horrible flare.

Thank's Paul and James

According to Hugyfot in Belgium it will work with the 17,5 cm FE domeport that I already have for the Nikkor 10,5.

And I am shooting on a cropped (D200) sensor, so a lenshood might be a good idea. James, do you have a suggestion or reccomendation on how to shape/manufacture such an item for best effect?

cheers

I made one out of a piece of matte black paper cut to fit. Not the most permanent though so you might consider one of the commercially available rubber hoods that you can cut to fit.

Actually, it looks like there is already some sort of hood on the lens:

The most efficient hood you can make would be one made from a plastic tub of the right size, that fitted over the existing lenshood and with an appropriate rectangle cut out of its base (trial and error on this). Paint it matt black inside and out to minimise flare (which these ultra-wides are very prone to) and ALWAYS ensure that it is fitted square on to the lens so that you don't get uneven vignetting.

Sure, it comes with a built in lens hood, but that's for use on full frame cameras. With a cropped sensor, you can make the hood stick out a lot more w/o appearing in the shot - thus helping minimize flare.
