I am pondering my next purchase and what better place to discuss than this forum 
Ok bottom line is there much point in me getting an UWA with me already owning the 17-40, i mean we are only talking effective 7mm- any thoughts?
If anyone else has faced this dilemna let me here what your reasons were- no matter how strange 
Not sure whether to go for the 10-22, the 135L or stump up a bit more cash and go for the 35L- each lens completely different i know- its a sweet shop condition.
Am very confused at the moment, any thoughts from you lovely helpful people would be appreciated. Many thanks.
