I recently traded my 7d for a 5dc. I had a Sigma 30mm f/1.4 lens and a Helios 44-2. I'm looking at buying a new lens. What has me drawn to the Samyang manual focus lenses is the superb image quality and large aperture. I ordered a Canon EE-S focus screen for the 5d, and plan to buy either the Samyang/Rokinon/Bower 35mm f/1.4 or the 85mm f/1.4 or the Canon 70-200 f/4 non-is. I have owned the 70-200 in the past and know it's a great lightweight sharp lens.
I am wanting to get into more people photos and portraits, so the 35 and 85 draw me to them. I really enjoy the full frame depth of field and the f/1.4. I'm not so sure the f/4 of the 70-200 will give me the "look" I want. I need persuasion on which to purchase as my primary lens for the 5d for a couple months.
I plan to shoot cars, people, and random shots walking around such as sunsets/barns, etc.
I can't stop looking at this photo using the 35 f/1.4 on a 5d(NOT MY PHOTO):
