For someone with the Canon 20D and Canon EF 50mm F1.8 II lens, would it make more sense to upgrade the 50mm to a Canon EF 50mm F1.4 USM or keeping it and getting the Canon EF 24mm F2.8 for indoor low-light / available light photography in a museum / restaurant? Any other suggestions?

You do realize the f/1.4 is two stops faster (just 4 time more light capability) than the f/2.8
If you have the room to backup from I'll go with the f/1.4!

Even though the 24mm is an excellent lens it's not USM - you can pick-up a really good Sigma 24-70 f/2.8 EX (not HSM either) for not much more and have a fantastic 70mm f/2.8 to boot - Remember on a 20D you're not using the performance of the lens at the peripherals: the center 13mm image circle part of almost any full-frame lens is plenty good...

I'm in the same situation - wanting a fast normal prime for my 20D.

At the moment the front-runner is the EF 28mm f1.8 USM, but I'm impatiently waiting for the Sigma 30mm f1.4 HSM to see what price it comes in at. The Canon 28mm can be got for around £325 and I suspect that the Sigma will be available for around £200.

I "need" this lens before the end of May so I'm anxiously awaiting the release of the Sigma.

Sigma also have a range of 3 EX f1.8 primes at 20mm, 24mm, 28mm. Optically they all seem good but the AF is universally regarded as being quite slow, if you can live with that they're definitely worth a look.

I'll be careful with a fast WA @ large aperture: While this combination works well for sunrise/sunset at infinity (I do this all the time) - indoor you're still limited by the DOF

-> at 10ft the DOF of the 30mm for example is only ~2ft which is good for a statuette, but not for architectural landscape of an entire room for example :?
