عدسة Canon EF 24-105mm f/4L IS II USM

The GMo aspherical lenses really do make a difference in sharpness corner-to-corner, even wide open. Distortion is noticeably lower than my older zoom, which makes cityscapes look much cleaner. A solid upgrade for the money.

The constant f/4 aperture across the whole zoom range makes shooting in changing light seamless, and the image sharpness is noticeably better than my older kit lens.

I was worried about distortion with a wide zoom range, but the fixed f/4 aperture stays bright and consistent from 24mm all the way to 105mm. That balance of image quality across the entire focal length is exactly what I needed for event photography.
