EDITED: sorry for the mistake..i didnt notice. thanks for pointing it out Sp00kY
It's not like that at all actually. Tamron DO NOT YET produce lenses with high-speed & silent autofocusing motors like HSM (Sigma), SWM (AF-S Nikon), SSM (Sony), USM (Canon).
There's basically two types of built in motor, Ring-type and Micro.
-- Ring-type is normally found in large-aperture and super telephoto lenses.
-- Micro is used in more compact lenses.
Tamron lenses which have built in motor all use the micro type motor which is slower than the internal bdoy motor. It is also noisier.
Example:
Ring-type motor - Nikon AF-S 17-55mm f/2.8
Micro-type motor - Tamron 17-50mm f/2.8 (A16NII - model number which indicate the built in motor version)

HDR is like PP la. No point to do PP if the original image isn't nice. Best to work on the composition, shutter speed to get the right blur effect. Once everything is nice, then only you decide to HDR or further PP.
With regard to UWA specifically the Tokina 11-16 for weddings, I think the range is too limited and it is very very wide at the long end. I have no experience doing any paid photography, but I imagine with so much going on during a wedding, you don't want to be taking on and off lenses in order to capture the moment, unless of course you have two camera bodies with two different lenses attached. Even then, perhaps a normal wide will be more than enough.

Good to have lens that can do double duty instead of being specific for DX only. Dats why I lub

the D series lenses.

Yes the range of Tokina 1116 if compared to Sigma 1020 is limited but maybe that is why the IQ is better than the Sigma. A DX normal wide at 18mm is definitely not enough, ask any who does weddings or events.
Lets say you have a group photo and you dont have enough space to move backwards...what will u do to take the whole group in your shot? UWA.
To put a bride and groom in a short distance away from my camera so that they are clearly seen in the pic and at the same time have a wide scenery...this aint possible with even the tamron 1750. not wide enuff...
Yeah, I go shooting with a friend or two..this aint rambo where i can just shoot alone, i need backup..
