No ultrawide primes for cropped sensors?

samyang 14mm is cheap and neat. An ideal solution for ultra super wide angle on Full Frame camera. It would be cool to have a 8 or 9mm prime for the rest of us poor souls stuck with crop...

8mm f/3.5 Rokinon (Vivitar, Samyang, Bower, Pro Optic, etc. all the same)
Reviews seem pretty good, and its only $300!
Cheers!

That one a fisheye no? Once you correct the distortion, it's not going to be so wide anymore. Still, if you dont care the crazy distortion, it's always an option!

I think 14mm is generally going to be your widest non-fisheye prime lens. If you need ultra wide and fast on a crop, then get the Tokina 11-16 f/2.8 and keep it at 11mm.
I think the fastest wide non-fisheye prime lens available is the Sigma 20mm f/1.8

tokina has the iq just like the prime
Im waiting for the mark 2

The Sigma 8-16mm, while not a prime is wide and well reviewed.

Yep. And slow too.

Slow is fine if the lens is cheap. For telephoto you need fast and DoF. On a wide lens you're not going to get much DoF anyway and the wider the lens, the the longer you can slow your shutter speed.

Problem is there's no UWA for less than 450$ and they are huge beast.

Actually wide lenses produce the most depth of field.

As far as really wide primes go on crop sensors, there are the Canon EF 14mm f/2.8 L USM and the more expensive II version, and the EF 15mm f/2.8 Fisheye which can be defished to be pretty wide. Sigma also made a 14mm f/2.8 rectilinear prime which I haven't tried but gets good reviews as well as a few fisheyes. After that you are into manual focus lenses but i don't think you will find anything rectilinear wider than 14mm other than maybe the 13mm f/5.6 Nikon which would be ridiculously expensive even if you could find one.

Really? I understood that the DoF is the same (with similar f-stop and distance) but the longer lenses zoom more in it, making the circles appear larger.

Actually the samyang 14mm would be perfect even on my crop sensor if I didn't have already a 15-85mm. I guess that's what frustrating me. However that lens make sens for people with a 17-55mm lens.

That is only approximately true with the same f-stop and framing if it is not at large magnifications (macro distances), and not near the hyperfocal distance. The hyperfocal distance on an ultrawide can be closer than the min focus distance of a long telephoto. Infinity is a lot of depth of field.

There's simply nothing available on crop that acts like a 24L on ff.

You want a fast UWA prime? Go ff
