Review on Rokinon RK8MS-E 8mm F2.8 Series 2 Fisheye Lens for Sony E Cameras - Silver: Capture Stunning Wide-Angle Shots by Justin Munajj

Great for sky or landscape shots, this lens fixes corner color cast issues experienced with some version 1 cameras. However, the minimum focus for a fisheye is not good, it is actually difficult to blur objects. Center sharpness at f/2.8 is good, and it's good across the frame when you stop down. You'll see some solar flares in the frame, but you'll also get some pretty good starbursts if you turn down the aperture. It is excellent for 180 degree (diagonal and near horizontal) starfield and sky photography. The lens has a different projection than most fisheye lenses. It is equiangular (also known as stereographic), which preserves the angles between objects. This way you still get a slight perspective distortion (stretching of objects near the edge of the image) but less center bulge than with a classic equidistant fisheye. Because of this, your horizontal and vertical field of view is slightly wider than a 10mm fisheye, but the diagonal is the same 180 degrees. I recommend this as a fisheye where you're mostly shooting at infinity. Close focus is sharp but very wide for a fisheye. You won't get much magnification from this lens at all. If you want dramatic close-ups look elsewhere, if you want excellent quality fisheye for landscapes, cityscapes or skyscapes this is your lens.
