I have simple cheap Canon lens and Canon XSI. I need to know what difference i will see if i take a picture with simple cheap Canon lens and then with Canon white L lens - same picture. What do i get if i use L lens, for example 70-200mm f/4L USM ? Please be specific. What will be different ?
question is not about F stops.

If you take a shot with your "simple cheap lens" in it's sweet spot you may not see a huge difference. Being that I don't know what lens you have nor do I know what L lens you'd want to compare it to I will be very general. Surprisingly, some of the IQ differences may be subtle, but they are there. You probably will see better CA characteristics, less distortion overall, less light falloff in the corners, and sharper in the corners. You'll also see a considerable improvement in build quality and sealing.

What about sharpens and colors of whole image ? Light is frequency and it means better Lens will have different light frequency than simple one.
I got 18-55mm IS F3.5-5.6 lens that come with Canon XSI and 55-250mm F4-5.6 IS lens - both simple cheap grade. I want to compare with Canon 70-200mm f4 USM - about $500-600 used.
Will it give me better colors and sharpens ?

i saw pictures on your site - they colorfully alive and sharp. What lens/lenses do you have ? Or do you use cheap ones ? Probably not because they all colorfully alive and sharp.
Why do you use good lens - answer this question considering you always have enough good light.

Why don't you just go out and rent one to see the differences yourself

yes, i am thinking about it. But will i really see the difference ?
If i go to Fresno Photographer Mariano Friginal, Fresno Wedding Photography & Portrait Photography i see sharp images. I know you can add colors and sharpness in Photoshop but i wonder how much color and sharpens improvement will i get from L lens ? Everywhere i only see post processed images but no photographers are ready to show straight of the camera image. Are there web sites to see straight of the camera images of different lenses ?

You have to understand that sharpness and vivid colors are not only a factor of the lens but also f/stops used, exposures, post processing, camera setup, focus point selection, etc. Most of our portrait work is done with primes, (35mm, 50mm, 85mm) and not zoom lenses. However, we will on occasion use the zoom lenses we do have. And they are not the high priced ones just to be clear on that.
