Samyang is going to announce several new lenses in Q1 2010: two version of 35 mm for FF with max aperture f/1.4 for Nikon, Pentax, Sony and maybe Olympus 4/3. The second version with max aperture of f/1.2 will be only for Canon. Canon bayonet has a bigger diameter which will make this possible. It is expected those lenses to be with an ED element and at least one aspherical lens.
Here is the current offering from Samyang on Amazon and their prices.
