Review on Rokinon FE75MFT-B 7.5mm F3.5 UMC Fisheye Lens for Micro Four Thirds (Olympus & Panasonic) - Black by Abdirahman Mensah

This is a very cool lens for little money. OK, I know what you're thinking. MANUAL lens, but FISHEYE? Called from the 1970s, they want their lens back! But no, seriously, it makes a lot of sense. First the MANUAL part. This is a 7.5mm lens. Of course there is focus control, but the depth of field is absurdly large anyway. You don't need autofocus with this lens. If you're at infinity and f3.5, you're sharp from about 3.5 feet to infinity. Moving back a little from infinity to use your hyperfocal range gives you another foot or so. You can focus, but for many shots it's not necessary. Manual iris you say. actually I do. But think about it for a second. You don't use an SLR camera, you use an EVF camera. When you stop, your electronic viewfinder adjusts. Unlike with a DSLR, you can't see that the lens is covered, at least in the AGC area in the viewfinder. This is the main reason why manual lenses for EVF cameras are very popular. Well, that's the video. Further. FISH EYE? Isn't that a stupid distortion circle in the middle of the picture? Well, you're half right. This is a full frame fisheye equivalent to a 15mm fisheye on a 35mm camera. Fisheye in design, not in focal length. A wide angle lens tries to be straight - straight lines stay straight. Is it expensive. Fisheye allows for linear distortion, so everyone is familiar with the "fisheye effect". The fact is, we really are living in the 21st century now. There are tools to eliminate the fisheye effect in fisheye recording. Google "de-fisheye". There are three or four easy ways to convert a fisheye shot to wide-angle in Photoshop if you don't like the fisheye look. By now you have 180 degree coverage. It's wider than the more expensive 12mm non-fisheye lens I have on my full-frame Canon DSLR. The build quality on it is excellent. while it looks a bit like the plastic lenses of the Olympus m43, it is made from higher quality plastic and metal parts. Image quality is very good at f3.5 and excellent at f5.6.
