I was shooting new born lambs in a barn and I had to close the camera to f/5.6 or smaller to make sure the mother head just behind was in focus. Previously with my every day lens PL 12-60 I would have taken that shot at f/4 and it would have been perfectly crisp small gritty and green

Fisheye Imaging Lenses Edmund Optics

There are many fisheye lenses that you can choose from, but here we're using Canon’s EF 8-15mm f/4L Fisheye USMwith a 180-degree angle of view that enables you to create circular fisheye images, as well as shots with full-frame coverage. See more Fisheye lenses enable you to achieve a large depth of field. So we’re going to shoot with an aperture of f/8, to maximise this, and use the ISO and shutter speed to control the … See more With its enormous field of view, we can get down and close to the subject, exaggerating the perspective. This achieves a low angle that wouldn’t be possible with a … See more Shooting at f/8 severely limits the light – especially at dusk, to get that sunburst. Expose for the sky, as that’s tricky to recover in post, and ensure that you’re shooting Raw so … See more With a portrait lens and/or a shallow depth of field, you can disguise almost any background – but with a fisheye, you’re going to see everything. As this image shows, a bad background can ruin your shot. See more http://www.bobatkins.com/photography/technical/field_of_view.html A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens. Instead of producing images with straight lines of perspective (rectilinear images), fisheye lenses use a special mapping ("distortion"; for example: equisolid angle, see below), which gives images a characteristic convex non-rectilinear appearance. small grizzly screen
