Do you have an extra $2000 laying around? If so, I would suggest coming to Dubai with us, but you might also want to buy Canon's premiere portrait lens, the 85mm 1.2. Mark calls this lens "the magic lens" because of it's incredibly shallow depth of field that can make almost any location look amazing. For a similar look check out the critically acclaimed 85mm 1.4 by Sigma.
