Isn't distortion always a slight problem in ultra wide lenses?
Smeggypants comments have kind of had impact on me and I'm actually considering the 10-17mm now...I've also read about the distortion of the fisheye effect decreasing quite a lot towards the 15-17mm end of it, if that's the case I could see it being a useful thing when i'm travelling as I probably wouldn't shoot all things at the wide end but probably more at the "narrower" end of the lens (well it's still 15-17mm which is quite wide), and the fisheye effect will nicely compliment when I want to be creative...
and also de-fishing shouldn't be too hard if I can find a lens profile somewhere?!?!

thanks a lot, I've read most of the reviews there and just can't come to a conclusion as they all say something different and it's hard to choose, I'm also somehow attracted by a 10-17mm fisheye which seems to be very fun to play with but not sure how practical will it be for travelling uses...

thanks guys that's pretty much all i've heard about the super wide zooms, but really like to find out more about the tamron since I'd quite fancy the extra zoom coverage...

I often see people praise about the DA 12-24, which we all know is great but also very expensive and I can't afford it, wondering if anyone's used the tamron 10-24mm, or would be able to recommend some cheaper ultra wide zooms?

or £360 posted to UK for a direct sale?

Trying my luck, but I can't justify keeping my DA 17-70mm F4 since I never use it. Looking to swap for a Tamron 10-24mm plus a little bit of cash.
It comes with it's hood, both front and rear caps as well as the box!

I'm in a bit of a similar but different situation,
After travelling I've not used my 17-70 f4 at all and am very tempted to swap it for a tammy 10-24mm since I go outdoors so much and the wide end seems a lot more useful to me.
The thing is I lose the length, though I have a 43mm 1.9 and a 1.7 AF TC to cover that end, so I might actually replace my 17-70 f4 with the 10-24 plus a cheap zoom

Ok, maybe put a price up. £80 posted ono

In very good condition and also comes with the original box, haven't actually used it at all since I bought it, never shoot at that sort of length...
Open to sensible offers, buyer pays postage (£5)
cheers

I'm interested in making a dive into macro photography, and being an owner of a 1.7x AF TC I'm thinking about getting a manual lens and use it with the AF adapter to get autofocus...
Just very confused about which one to get, or even a M42 lens + mount??!!
Probably looking at the cheap end at the moment...
Thanks for the help!!
