The Rokinon 35mm F/1.4 is surely a nice lens to have in your kit - especially nice when there's a discount available. Normally about $500 dollars, today it's part of Amazon's Lightning Deals which is usually the best price you'll find anywhere. The deal was so good last time (just $350), I ended up buying a couple for my friends who missed the sale. They also only run a limited quantity during these sales so be swift. Check it out at the Lightning Deals page (Click here).
