Sigma Lenses For Canon T1i
Is this a good choice?

T1i Currently I have a Canon lens with a 18-OS-200mm Sigma and a Canon f/1.8 50 mm. As Canon 50 mm that is a very strong target for the price, that the addition of a 0.45x wide angle lens to be better than if I was using my Sigma lens, or the quality of image, are disadvantaged? And right now I can not afford a wide angle Canon first sadness.

One source is a green screen. I put my camera on a tripod and began testing. I have a Canon T1i. I have a manual mode ISO 100, F-stop 5.6 and the shutter is 1 / 25. I'm using a lens Sigma 28-70mm DG of 2.8 to 4. I do not really know how to set up lights, stage, location, and power. My questions are: • Setting my good camera? • How do I pay light? • Are there better lenses that would make a difference? I took pictures Search faded and not crispy. And it is difficult to achieve Backlit with enough without washing my theme.
