Shedd Aquarium is one of the "places" I'm going to visit in Chicago - so thank you for the information... I'll need to get that 50 before my vacation

the lens is darn cheap comparing to any other 50mm. For the money the lens has the best value. In fact some copies are sharp event wide open. F1.8 is a fun lens and a must have considering the price

my first camera was 20D and the only lens i got along with the camera was 50mm F1.8 which i had for almost 3 months before getting a 17-50 lens. I still believe the initial 3 months with the 50mm made me learn about composition on my own. Not only composition but also various aspects of the camera functions. I will still credit all my learnings to the 50mm F1.8.

It is a great prime for the price.

Which one will render better bokeh? 50 f1.8 or 85 f1.8?

The longer the focal length, the shallower the depth of field, but lack of IS definitely becomes a problem with longer focal lengths if you shoot handheld. One of my friends very kindly gave me his Sigma 105mm Macro which is very fast at f/2.8 and the bokeh is beautiful, but it is extremely difficult to take handheld shots in low light without a flash, even with the large aperture and high ISO.

Not really the lens is fast enough to combat the need for IS. At 100mm you will want IS at 2.8, but I have the 85mm 1.8, and if you shoot down at 1.8-2.8 IS is not a issue. I still have fast enough shutter speeds to avoid camera shake. Also the lens is shorter and lighter, so it balance better on the camera. Which help against camera shake.

I remember the zoom lens I had for my D90 - 135-400mm and f/5.6 max aperture, no stabilizer lol

85mm f1.8. It has 8 blades aperture compared to the 5 non-rounded blades on the 50mm f.18.
