I just got a rokinon 12mm fisheye for my canon 5d Mark ii. So far this lens has been super fun, but now I'm thinking of getting a wide angle to do some real estate photography. I'm no pro or anything but wanted to see if I can make a little cash to compensate the purchase of a lens. I was thinking of getting a sigma 24-105 art series lens. I've heard great things about it. I was just curious to know if this is a wide enough angle for the full frame camera? I don't want to spent a ton of money on a lens. Any suggestions? I've done some research and a lot of lens that I've read online are referring to lens that is capable to only a crop sensor like the canon 10-18mm or 10-22mm. Need some feedback and suggestions! The sigma 24-105 is also good for the overall walk around lens. I eventually want to get a 70-200 f4 in the future to shoot surfing.
Thanks for the help!
