For Canon xti
ultra wide or just wide?
ultra wide Canon 10 22, Tokina 12 24
wide Canon 17 40 4.0L, Tamron 17 50 2.8
sigma 17-70 f/2.8-45
Is there sample shots taken with these lenses? I'm just getting into photography.
I got to go now but ill check this thread later
I'll second this. I have this lens and it's fantastic.
me too I just got it
What kind of wide angle? And what price range?
Tokina 12-24 or tamron 17-50 f/2.8....
hmm, not sure really. Something for landscapes and outdoors I guess. For price range...Maybe sub 500 if thats possible.
What is better.... @ f/2.8 or @ f/5.6 and why?
Thanks in advanced for all the responses guys.
f/2.8 - its a larger aperture (more light can come in, more background blur, less DOF)
just to add - a faster lens allows more light in. Under low light conditions, this allows you to shoot at a lower ISO. A slower lens (ie f/5.6) requires more light, so you have to shoot at a higher ISO or a slower shutter speed.
My policy is to always go with the faster lens, even if it means more money, unless there's a slower, but still acceptable, piece of L glass available. Like the debate between the Tamron 17-50 and the Canon 17-40L, the L glass is a better build and has better optics, but is significantly slower, but will last you a lifetime. But on a crop body, with no intention of going balls out pro (5D 1D), the Tamron is usually the more economical and smart choice.
had the sigma 17-70 & loved it. great lens for around $300.
My only issue with the sigma 17-70 is that its not a fixed f/2.8 If it ends up being an issue I might sell it and get some L glass
