10-24mm Lenses.

[Tommo224]

Hey all, I'm looking in to ideas for my next lens (down the track). I dwell, sit on the idea, and read in to things for a while before buying!

I would like something wide angle, but I don't know how wide I want to go, and I don't know if it is worth spending more on something with a lower f-stop number thing or not. However, on all of these, I've figured that I could be happy with at least one of them!

I have a Sigma 30mm f1.4, and I love how low I can set the thing, but when it comes to wide angle I've read that you don't really need to drop it that low (I read you can end up with ugly bokeh). Would it be worth spending money on a 15mm or 20mm lens? Would there be that much more view range? I know it may be hard without knowing my photography style, but I tend to easily blend in with whatever the capabilities of the lens I'm using is


I have a few in mind (I chose this store because they have a shop front 5 mins from work, in which I can cut my list down and try-before-buy lol):

Sigma 15mm f2.8 - $869

Anybody here have experiences with any of the above lenses, and is anyone able to give me good/bad comments/comparisons with any of the above? (Such as, if you've used 1, 2 or more of the above, etc etc).

Price is also a factor, so if you think one isn't worth spending more on than another on the list, could you please let me know?

Thanks in advance!!
