Lightest/sharpest 16mm prime for Canons?
I'm looking to replace my dinosaur 16-25mm 2.8 II Canon brand lens, it's been through the wringer and ready to retire. I use the 16mm range so frequently, I'm looking to save my wrists some strain (from all those slow shutter spins @ the reception) and just get a prime 16mm.... and it has to be a 16! I have a 14 fisheye and it's too wide, the next up I have is a Sigma 35 and that's too narrow. 16 is my sweet spot apparently. I see a few manual focus lenses for this (why?!?) and I'm okay with that, but I've never used any of these brands- Rokinon/Samyang/Tokina. Does anyone have experience with this?
