Review on 📸 Rokinon 300M-FX-BK 300mm F6.3 Mirror Lens for Fuji X Mirrorless Cameras, Black - Enhanced SEO by Emily Wilson

This is a good compact telephoto lens option for Sony NEX cameras. I use mine on the A6000. If allowed, my rating would be 3.5 stars. It has all the ins and outs of a well made SLR lens. Pros: It's small. It's about the same size as the Zeiss 16-70 but much lighter. Pinning focus can also produce great results. Dogs and geese - full face but the kestrel is removed - extreme crop. The bad: Most of the bad things about SLR lenses in general are just a fact. Firstly, the lens has a manual focus and an aperture setting - 6.3. At 300mm, this is a shallow depth of field. You need to nail focus with focus assist zoom. Peak focus gives you a pretty good shot when you're filling the frame like a dog and geese, but for a shot like a kestrel you'll need to use focus assist. This isn't for a quick shot, and expect lots of misses. There is also no optical jitter reduction system. So you need to use this lens with a high shutter speed, at least 1/500 and preferably higher. This also means that the image is very blurred when using the focus assist. Then comes the weird bokeh (out of focus) of the SLR lens. You can see it in the geese photo. This lens is not a performer. my best ED 300mm f/4 DSLR autofocus lens, but it's about 1/3 smaller and 4 times the price. In terms of sharpness, it's comparable to a 70-300mm zoom at 300mm, but without autofocus. It also pairs well with the A6000 and is good for places where I wouldn't take a large birdwatcher.
