I have a Nikon D300 and looking for a wide angle lens for an upcoming European holiday. I am looking to do wider angle landscapes and imagine the new lens will be useful in some of the cathedrals that we will be visiting. I also hope to get a bit more creative with landscapes when the trip is over. As the equipment below indicates, I have the 18-135 kit lens already.

I am trying to decide between the Tokina 11-16 F2.8 and the Nikon 10-24 F3.5.

I have heard and read about of back focus issues with the Tokina but it is only two thirds the price of the Nikon. ($829 v $1225). Is this fault as common as some of the reviews indicate or is it just a few problem lens creating the feedback and the good lens not having comments made?

Can anyone give some feedback on their experience with either lens?

Any suggestions or comments would be appreciated.

Thanks,
Greg
