Hi,



I currently own a Canon 15-85 f/3.5-5.6 lens. I'm very pleased with the IQ in a good lighting/outdoors,

but i find it a little slow indoors or on a very cloudy day.



I wonder if the Sigma 17-50 f/2.8 will bring much difference to my shots.

Can anyone post some examples of shutter speed differences between the F numbers?

I suppose there won't be much difference between 2.8 and 3.5, but what about others?



Thanks
