actually my widest is my 16-45 Zoom.
I use it quite often because It can focus on something almost touching the lens...
The Tamron 17-50/2.8 is also great like that. But since you already have the 16-45, you'd really have to value the speed to go to the Tamron.
What's your budget look like? If you want something special, the Zeiss Distagon 35/2 is available in K Mount & M42 and will/should be cheaper than the 31/1.8 limited. The Ziess is Manual Focus, but i'm guessing you already knew that.
