Amazing 6

I had only the Olympus Body Cap gained me 9mm to get a taste of fish eyes. With the Olympus Viewer can 9mm shooting still correct something: CA is considerable (but to judge) and the distortion can be adjust to Wide level (if it must be because). The edge sharpness in the corners, however, remains doubtful ...
Not so with the Samyang! Not only the difference in screen sizes is significant, the fisheye effect is much greater, but the picture is just perfect: sharp, contrasty, without CA. For me convincing already from open aperture. The correction on conformality is hardly feasible, it's just all around nice and bulbous. I have tremendous fun on the shard.
But there are two points to note:
1. The manual focus is absolutely no problem, the depth of field in the optical includes yes pretty much everything
2. The lens has no aperture jump: That is the darkening of aperture 22 in the viewfinder before it gets a little dark, with little light

So the 300 are well laid out, a more interesting objective for this money you can find hardly. Set course, the Apetit on fisheye is available.
