I am thinking of getting a wider angle prime lens that doesn't cost an arm and a leg. I see Rokinon and Samyang which cost in the low US $300's, but I want to get folks' opinion first before making the choice. Any help would be appreciated.
For me, the choice was between the Rok/Sam 12/2 and the Sony 10-18. But, the latter gets you back into arm/leg $$.
I chose the 10-18 for it's range of FLs, which I knew I would get use out of with my interest in landscape and architecture photography. It complements my 18-105 perfectly, making for a great 2-lens solution.
But, if I had more interest in astrophotography, I think I would have happily gone with the Rok/Sam 12/2, saving a lot of $$ in the process. I agree with the others who say autofocus and stabilization are overrated at this focal length. When it comes to astrophotography, they're a hindrance IMO.
