Polariser for Sigma 10-20

JMcL

Hi all,

I treated myself to a new lens for new year, and need to add a polariser, does anybody have any recommendations for or against. I'm tempted by a Hama, which can be had for £18 from 7dayshop, and I'm pretty happy with the one I have on my 58mm lenses. The slimline Hoyas are a bit pricey, and I also had a look at the 105mm one that attaches to the Lee system (tempted by their ND grads), but the price of that is really scary!

My fear is of vignetting, as it's a normal size filter (it'll be on a 300D). I took a few test shots with one in the shop, and didn't seen any significant vignetting, but the conditions weren't really that ideal, so what're peoples experiences in the real world?

If it's only an issue when the lens is wide open, the that's not that much of a problem for me, as the camera will mostly be on a tripod and stopped down.

Fajitas!

I have a Hama for mine. You're from Waterford yeah? Mulligans should have them in stock. It won't vignette if you only have the Polariser on, but will if you have anything else on with it.

That's not true Fajitas, the 10-20 will most certainly vignette with a normal polariser at least below 14mm (maybe 16mm, my memory is hazy on what I read at this stage). You definitely do need a slimline one. I spent quite a bit of time researching before buying. On my last trip to the states I picked up the Nikon 72mm slimline CPL. I like it. Expensive, yes, but as many people will tell you - putting a cheap filter on front of an expensive lens is a bit silly. There will be image degradation.

My reason for going with the Nikon in particular was that many/most/all of the other slimline ones that I saw on B&H lacked a front threading. My great master plan was to attach the Lee system to the front, that I also got. It does work but it's tough to turn the right thing without holding the filter holder. It's doable though.

As for ND, I went with HiTech. Better and more expensive than Cokin, designed for the HiTech filter system but it mounts on the Lee holder (Lee even sell mounting brackets for it - that said, I didn't use them because I found it *too* tight). Much cheaper than the Lee ND or the Singh-Ray.

I've got the slimline Sigma DG circ-pol on my 10-20mm. It's very thin, much thinner than the Hoya ones I have for my non-wide angle lenses, probably no more than 4-4.5mm or so. Oh yes, and it's front threaded too.

Cheers, I'll check them out

Wouldn't agree with that, I've used a polarising filter many a time before without difficulty.

I agree with fajitas ,you only get vignetting when you leave the uv filter on .
unless you buy the specific sigma polariser which frame is a lot thinner so you don't see the metal frame in the corners.
sigma one is a lot dearer though

Hmm... that might be a Nikon/Canon issue (I'm assuming you're a Nikon user halenger) AFAIK, the Nikon sensors are a bit bigger that the Canon APS-C sized ones - 1.5x versus 1.6x, which would make them more likely to vignette.

I had a look at the Sigma, and it is pretty nice, though still upwards of €100, which I'd rather not spend at the moment while perched on the Lee (have to research the Hi-Techs a bit more too) ND grad fence (this is where I get myself by treating myself to a Joe Cornish book for Christmas ). I did pick up a Sigma UV filter though, as I got it almost thrown in with the lens

Fair point JMcL, I didn't even think of it at the time. Carry on.
