It's not surprising. A 20mm lens is an ultrawide angle, and therefore can "see" the edges of most lens hoods..

You need to look for a "flat" hood which extends out to the sides quite a bit before it starts to extends forward. And it should not extend very far forward at that..

For lots of money, look for a petal shapred hood, which has straight sides and cutouts in the corners..

For cheap, look for a rubber lens hood and a pair of scissors..

Thanks for the quick response. Most of the hoods I found don't go lower that the 28mm mark, which is fine for putting it on my 30D, but I simply haven't found *anything* that claims to work at 20mm (expensive or otherwise)..

I have seen a few rubber ones, but how do I test it on an analogue camera without wasting a bunch of film? Do I just look through the view finder and cut the hood until I can't see the hood?.

The Sigma website lists Model # LH875_02 as the lens hood made for this lens..

Sorry but what made you think I got the Sigma 20mm f/1.8? The lens I actually got is a Carl Zeiss Jena Flektogon MF 20mm f/2.8 with a 67mm filter thread which is where I plan on putting the hood..

Cheers,Smog..

Hi,.

20mm is a bit extreme in terms of lens hood and the front element might just be recessed enough apart from straight into the light shots..

Have you asked the makers what they recommend, btw? Makers often make things that don't get much publicity....

Failing that, buy a sheet of black matte card and use a pair of scissors and a bit of sticky tape. There's a web site somewhere devoted to it..

Regards, David..

According to Wikipedia Carl Zeiss Jena became Jenoptik in the early 90s and it seems that they don't make camera lenses anymore (the site was in German, but it seemed like the majority of their products were laser optics)..

Last night I found a guy selling a metal lens hood online that he used with his copy of the lens and told me it worked alright, and the price isn't bad at all..

Oh and the printable lens hood site is this: http://www.lenshoods.co.uk/I was considering this before I found a guy selling the appropriate lens hood..

Thanks for the ideas,Smog..

Hi,.

Thanks for the link. C Zeiss gets it's name on a lot of lenses though..

Regards, David..

I'm sorry, I don't know where I got the Sigma part from. I must have been thinking about another thread that mentioned one.Scott W. McClure.
