Questions & Answers

JOSEPHINE M : Since this is a static 300Mm, what is the 'wide" measure? 18mm, 24mm ?ANDREW R : I'm afraid I don't understand your question. This lens is a single focal length, 300mm.
JOSEPHINE M : Will this work with the Sony a6300?ANDREW R : This manual focus lens should work with most Sony "E" mount mirrorless camera bodies.
Shopper : Why Did You Choose This?ALEX C : Inexpensive 300mm. Won’t know if it’s right for me until I try it.RICK M : Reviews

Rated 2 out of 5

Razor thin focus

Given this is a manual lens, focal depth is extremely important. Unfortunately, when taking pictures of deer standing within 3 feet of one another, one was in focus and the other out of focus. When attempting astro photos from a tripod, I could not get the moon or stars to properly focus either.

Rated 4 out of 5

good construction, strong vignetting and limited sharpness

as stated in the title this lens represented a point on the compromise curve: very low cost, good physical construction, mediocre image quality. When shooting against any light background the vignetting is strong enough to make post processing a hassle. Sharpness in the dead center is also visibly worse than premium super telephoto lens. The other problem is the sheer difficulty of getting a good focus. I was trying to put it on infinity when shooting the moon, and it felt like that the focus ring needs to be placed with very high precision. I needed to do a 'focus bracketing'. Because of the low cost, I have to give this 4 stars rather a lower score reflecting its image quality. before you buy, check out all the reviews on the internet and think about your priority.

About Rokinon 300mm f/6.3

Just imagine capturing the distant wonders of the wild or the thrilling action of a sports event with precision and clarity. The Reflex 300mm f/6.3 ED UMC CS Manual Focus Lens for Sony E-Mount, presented in a sleek black finish, is a high-quality, durable lens that offers photographers a versatile and reliable tool for telephoto photography. This innovative lens is specifically engineered for Sony NEX mirrorless cameras, boasting a 450mm 35mm-equivalent focal length that brings distant subjects into close view without the bulk typically associated with traditional super telephoto lenses.

Crafted with a sophisticated Cassegrain design, this Reflex lens maintains a compact profile, making it an excellent choice for photographers who need to travel light without compromising on reach. Its high maximum aperture of f/6.3 facilitates faster shutter speeds and enhances performance in low-light conditions, ensuring that you can capture the moment with exceptional detail, even when lighting is less than ideal.

The manual focus operation of this lens allows for precise control, enabling you to focus on subjects as close as 2.95 feet. This level of control is perfect for photographers who enjoy the tactile experience of manually fine-tuning their focus to achieve the perfect shot. The inclusion of one extra-low dispersion element in the lens construction significantly reduces chromatic aberrations, resulting in images with superior sharpness and color fidelity.

Moreover, the inherent mirror construction of the Reflex 300mm f/6.3 lens not only contributes to its compact size but also plays a role in minimizing aberrations and enhancing image quality. The UMC (Ultra Multi Coating) applied to the lens elements is another testament to its innovative design, effectively minimizing surface reflections, lens flare, and ghosting. This coating also boosts contrast, ensuring that your images pop with life and vibrancy.

Whether you're a wildlife enthusiast, a sports photographer, or simply someone who appreciates the ability to capture distant scenes with clarity and precision, the Reflex 300mm f/6.3 ED UMC CS Manual Focus Lens for Sony E-Mount is a superb addition to your photography kit. Its unique combination of a long focal length, portability, and image quality makes it a standout choice for discerning photographers looking to elevate their telephoto capabilities.

Rokinon 300mm f/6.3 Features

  • Mirror lens designed specifically for Sony NEX mirrorless cameras
  • Catadioptric system with Cassegrain design helps to reduce the overall size of the lens while still providing a 35mm-equivalent focal length of 450mm
  • One extra-low dispersion element and a UMC coating are integrated into the lens construction to improve sharpness and clarity as well as enhance the overall image contrast
