Wide angle lens for crop-sensor videography and photography
We all know lenses are really important in photography and videography. I love the look of longer focal lengths, but in many situations wider lenses are needed. This is especially true for my personal videography as there isn't often a lot of space. I have found it quite difficult to find a good, not too expensive wide-angle lens for crop-sensor cameras (Canon APS-C). I really want a prime, as they are often faster and zoom-lenses make me lazy.
The ones that I've looked at are Samyang/Rokinon's 24mm t/1.5 cine, the Tokina 11-16/2.8 (all though it's a zoom) and even the Sigma 30mm f/1.4.
The Samyang seems really nice (although not great wide-open) but is a bit pricey.
The Tokina gives a wider image, but that gives a certain look in the z axis which I'm not a fan of. It's also quite expensive and not as fast as the other two.
Then comes the Sigma, which seems like a truly awesome lens, but with the drawback of the focal length; it's not that wide.
Is there some other lenses that I should look at? Price is a limiting factor, so try not to suggest too expensive lenses. Do you have any other tips?
