I cannot make up my mind!! I am trying to decide between the Canon 85mm 1.8 prime and the Tamron 28-75 2.8 zoom lens, I am starting to do alot more portraits, bridals soon and even a wedding in Nov. If you had to choose between the 2, which would you choose and why? Right now I have 50mm 1.8 18-55 75-300 and we all know that the last 2 arent that great so please HELP!! lol Thanks!!!!!!!!
