Topic: Siggy 10-20

Been offered a Sigma 10-20mm for £300 +£7 postage .
As I am looking to get into landscape togging is this a good deal ?
I know its a great deal cheaper than buying new but hows the second hand market holding up for these ?

I have no problem with mine, chuffed with the performance and bought new due to the relatively high s/h prices!.......

I hope that answers your questions?...... (BTW I assume you know they do two?.... a 3.5 & 4/5.6... I bought the cheapy!)

Andy.........

This is the 4.5/5.6 version as well .
I have actually found it new cheaper ! But as I trust this guy and don't want an import from HK I will stick with him 

Cheers Andy .

I know HK do some silly prices on Sigma stuff, but as Alex said how much would you risk?.......

I know you'll enjoy this lens, it's suprisingly versatile, and you can get some interesting perspectives too!.....

Andy......

I love my one Shane. It's a very good lens. Welcome to the world of ultra wide, just make sure you use plenty for foreground as it's easy to end up with a mass of very distant looking mush with no interest if you don't think really hard about composition.

Composition with that lens is paramount as Barry pointed out.

With Architecture, and in fact most things at the 10mm end what you need to do is get as close to the foreground interest as you feel comfortable, then take one step closer

Barry will probably be able to tell you what factors you need to plug into PS to remedy any distortion for buildings and horizons.

Actually it's pretty good in terms of pincushion and barrel distorsion. The main thing is perspective distorsion if the sensor plane isn't parallel to the object but that's useful too sometimes!

Thanks guys .
As I haven't used an ultrawide before I am looking forward to having a play with it .
I won't be getting it untill later next week ,but it does give me time to plan and get out over the Easter weekend break with it 
A CP filter would be a good idea as well I understand ?

I think that even the thin CP's are likely to give some vignetting at 10mm Shane. 

Ta Barry , I will get the lens first I think and then think about changes when I have used it .

I have a thin UV on mine?..... not noticed a problem?.....

Andy.........

Indeed but the thin CP's are thicker as they have the rotating element and a fixed ring which makes then nearly 50% wider IIRC. Personally I was put off by being asked to pay £140 odd quid for a pro spec filter and have happily gone without. I regret not attaching a UV though as I seem to have used my lens pen on top of a spec of grit and scratched the surface coating in a couple of places

I have UV's on all mine for just that reason!...... I wasn't aware CP's were thicker?.....

Andy.........

Because they have a stationary bit and a twiddly bit both of which have knurled bits I think (occasionally even I do) they are a bit thicker. I'd be interested if there is one that doesn't cause a problem on the 10-20 though.

I fancy the Siggy 10-20 too. I know people who rate them in high regard so i will be on the lookout for one at the right price.

Hmmmm, just read the blurb on the Hoya Pro spec CP, 5mm thick, all the others are 3mm, and as you say at 150 beer tokens maybe a bit too rich to risk!....

Try the cokin p system of filters, works with just about every lens which has a filter thread, about 50 beer tokens and pretty good grade.

10, cool, been using my 18-75 on buildings this month and love getting close with a nice distortion
got a little something in the post to make that even greater
never really used my small lens on wide angle before

Even with my P system on backwards (old indian trick) I still get vignetting at 10mm...

Andy, that's the one I was looking at till I decided I'd tweak saturation and levels in PS instead of having one!!

Looks like that question has pretty much been answered then ! 

Maybe the cokins screw in adaptor gets in the way on that lens?

You lot at least have the choice of some filters...my siggy 15-30 full frame lens cannot have ANYTHING put on the front or itll hit the glass...there isnt even a fiter screw thread

I do love my sigma 15-30 though, its probably the sharpest lens out in that range for a full frame camera, it blew the stupidly expensive nikon equivalent out of the water accross the frame Its like a secret weapon in the bag
