Nikon 105mm f/2.8D AF Micro Nikkor
9 out of 10 points and recommendedImage quality, 1:1 magnification, f2.8.Slow focus.Great macro lens that reaches 1:1 magnification. Good bokeh. Excellent image quality both for closeups and for more distant subjects. Even when not shooting macro, I keep using it as a telephoto for landscape (because it's brighter and has more contrast than my other zoom) and portraits.

Canon EF 17-40mm f/4L USM
9 out of 10 points and recommendedImage quality.Heavy. 40mm too short to use as walkaround lens for 1.6x sensor camera.Lens with excellent contrast and sharpness, especially at the wide end.

I use it on a digital with 1.6x crop sensor and sharpness remains excellent despite the smaller sensor.
Minor point, but the lens hood provided with this lens is ineffective for the 1.6x sensor (at the wide end, it's a '27mm equivalent') and gets in the way when using the camera's built-in flash. -
Canon EF 50mm f/1.8 II
7 out of 10 points and recommendedprice, sharpness at f5.6-f8, 1.8 max aperturepoor bokeh, cheap constructionThis lens is a great value because of its low cost and excellent sharpness at f8. Great for portraits on a 1.6x body, or for still life.

The main downside for me is that when used open to get background separation or because of low light, bokeh is very poor.. don't know how to describe it... it has a chunky appearance rather than being smooth.
At f1.8, depth of field is also less than the autofocus precision of 1.6x Canon bodies, and maybe my lens is slightly front-focusing... the result is that about 50% of the shots at f1.8 are from slightly to more substantially out of focus (especially in low light situations, and almost always with focus in front of the subject for my copy). AF is ok at f4 or up.
Despite these issues and the cheap construction, I think this lens is great if you plan to use it at f5.6-f8, hence my recommendation. Very sharp.
