Well, I'll have to say I'm gravitating to a certain set of objectives as well, though my job as optics designer sort of requires me that I have some knowledge of the common objectives and knowledge of using them too.
I admit I'm gravitating towards the shorter end of focal lengths, my most used objectives seem to be:
Canon's 24-70/2.8 I (not looking to II, this one is better for me)
Canon's 70-200/4.0 L IS
These lenses I do have as well, but there's something I'd like to change in them:
Sigma's 12-24 I - If this was a constant 4.0... I run against 5.6 on cloudy days
Sigma's 120-400 - 20 - 30 % lighter version would be nice. Or 300/4 II, if it happens.
Canon's 50/1.4 - Quite a long to list on what I'd like to change here. Though the motivation for this is just outside photography in low light, where I would not like to take the 1 kg behemoth.
Though, I can live with Sigmas, but that 50 mm update Canon... I'd also be interested in trying out a fast wide angle (something like 24/1.4 or 20/1.8 ) when I can find one that I like. After that I think I'm pretty much set.
What did not work for me? Well, 85/1.8 and 28/1.8, I don't use neither of them that much. Though they make a good light weight set for holidays with a crop body. And since I travel quite a bit with bicycle, long and or fast teles are pretty much a no-go. For example 200/1.8 was far too heavy for me, and 70-200/2.8 IS II sounded intriguing until I realized its twice the weight of the 4.0.
