In this article, I want to show the difference between ultra wide angle Samyang 14mm f / 2.8 ED AS IF UMC and fish Samyang 8mm T3.8AS IF UMC.
The photos below were taken at 14mm full frame and 8mm crop fisheye (signature side):
As you can see, the coverage of the fish is much greater. The Samyang 14m has a field of view of approximately 115 degrees, while the Samyang 8mm fisheye gives a 167 degree field of view at a 1,6x crop. It is difficult to say how many degrees the field of view is in a full frame, but much more.
И even on the crop a fisheye 8mm will have a larger field of view than a 14mm lens on a full frame:
Overall, both lenses offer a very interesting perspective. You have to get used to both. At first, the focal length of 14mm seems very specific, but this is until you pick up the fish. With an 8mm fisheye, you have to be very careful about what and how to shoot. Of course, the same goes for the 14mm ultra-wide angle. Either way, both lenses open up a lot of creativity. Everyone must decide for himself what he likes best (or shoot both :).
