Samyang 14mm or Rokinon 8mm fisheye? Which is better for landscapes?

Canon EF-S 10-18 or Tokina 11-16/2.8. :D Sorry. Neither one of these is ideal on a crop body as a landscape lens. The fisheye has too much distortion and would require defishing if you ever wanted a ...

Samyang 14mm or Rokinon 8mm fisheye? Which is better for landscapes?

I have the 14mm and use it with a T3i (still a crop body). I like it for what I get but I wouldn't consider it the best option. If time is not of the essence, I would recommend this: Canon EF-S 10-...

What can I do to protect a bulbous lens when no lens cap is available?

Until you find a proper one, I would simply fashion one out of some cardboard and gaffer tape. Or if you happen to find some plastic drain pipe of the correct diameter, you could use that.

Can we use a cine lens for still photography also.

Why does my Rokinon lens have no aperture control on my screen?
