Review Summary

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

Bring your photography to new heights with the Rokinon Reflex 300mm f/6.3 ED UMC CS Lens, expertly crafted for Micro Four Thirds mirrorless cameras. This innovative mirror lens employs a Cassegrainian design, delivering an impressive 450mm 35mm-equivalent focal length in a remarkably compact and lightweight form. Unlike traditional 300mm lenses, this model is designed for portability without compromising on performance.

The lens features a fixed f/6.3 aperture and a manual focus system, allowing you to focus as close as 2.95 feet. Its construction includes one extra-low dispersion element, which, combined with the mirror design, effectively minimizes chromatic aberrations. This ensures your images are sharp and clear, with vibrant color fidelity.

Enhanced with Ultra Multi Coating (UMC), this lens significantly reduces surface reflections, lens flare, and ghosting, resulting in superior contrast and image quality from the center to the edges. The minimized flare and ghost effects make it an excellent choice for capturing crystal-clear images in various lighting conditions.

Designed for convenience, the Rokinon Reflex 300mm lens boasts a compact and lightweight build, making it an ideal companion for travel photography. The smooth focus ring provides precise control, ensuring incredible sharpness in your images, which is particularly beneficial for indoor and night photography.

The reflex mirror lens design not only shortens the barrel for added convenience but also creates a unique donut-shaped bokeh, adding an artistic touch to your photographs. This lens bundle includes Hoya 58mm UV and CPL filters, enhancing your creative options and protecting your lens. Elevate your photographic experience with the Rokinon Reflex 300mm f/6.3 ED UMC CS Lens, where innovation meets portability.
