I'm a researcher at my university doing work towards my MSc. My field of study is photography and computer vision (pattern/feature recognition, image processing, etc).

I need a wide angle macro lens, at least f/4 (2.8 would be nice) for an application I'm working on. It needs to be as sharp as possible. If I had no budget, what would you suggest?

That's actually pretty good! It has tilt correction, too, judging by video reviews it works well. I take a lot of photos of materials from a tripod pointing downwards; tilt correction means I can have it more relaxed at an angle versus direct BEV.

How much magnification do you need? You could use basically any lens with some extension tubes for more magnification.

Feature recognition and pattern matching mostly, but I'm taking some things outside that but still inside computer vision.

A wider angle, yeah. 15-25mm is perfect. I have an 11-16mm Tokina lens which isn't as sharp as I need.

At least 1:1.
