So with the relative success of my first wedding shoot, I've booked a few more weddings in the next year. Looking around at other wedding shots, I see a lot of pics taken with the 85mm lens. I have the opportunity to buy the 1.8, or, I could take that money and rent the 1.4 several times over. I've been drooling over the cream machine, and I'm sure how much I'd use the 85 mm focal length. (Then again, I said that before my 50 and I use that one all the darn time). Thoughts? Opinions?
