Rokinon 7 5mm F 3 5 UMC Fisheye Análisis | 54 Datos comparados

This review highlights the Rokinon 7.5mm f/3.5 UMC Fisheye Lens as a high-quality, dedicated manual lens designed specifically for Micro Four Thirds cameras like the Olympus PEN series. On the positive side, the reviewer praises its top-notch, mostly metal construction that feels robust and lacks loose parts. It is exceptionally compact, measuring just under 2 inches long and weighing 6.9 ounces, making it an excellent physical match for small camera bodies. Furthermore, it delivers impressive image quality with crisp, clear results that remain sharp even at the edges, avoiding the softness common in other fisheye lenses. The tight, precise feel of the focusing and clicking aperture rings also adds to its premium tactile experience. Conversely, the lens has several notable drawbacks tied to its manual nature and extreme wide-angle physical design. Because it is a manual lens, users must carefully configure settings, like setting the focus near infinity and using aperture priority mode, to ensure sharp images. Additionally, the protruding front lens element means that photographers cannot attach any filters, though a built-in petal-style lens hood is included to mitigate...

The Rokinon 7.5mm f/3.5 UMC Fisheye Lens for Micro Four Thirds cameras is highly praised by The Gamer With Kids for its brilliant value and exceptional, top-notch build quality. Priced at $299 and available in black or silver, this dedicated fisheye lens offers a massive 180-degree field of view that captures incredible amounts of visual information. The reviewer notes that its mostly metal body creates a very solid, tight feel, and its tiny size (under 2 inches long and 6.9 ounces) makes it perfectly balanced for compact cameras like the Olympus PEN series. Optically, the lens delivers remarkably crisp and clear images with impressive corner sharpness, especially when stopped down to f/5.6. However, potential buyers must weigh a few specific drawbacks before purchasing this extreme piece of glass. Because it is a fully manual lens, photographers must adjust the focus and aperture rings entirely by hand. The unique, bulging front glass element means that no lens filters can be attached to protect the optics, though a built-in petal lens hood is included to help mitigate glare. The lens also introduces...

The Samyang 7.5 mm f/3.5 UMC Fish-eye MFT is an exceptionally compact, lightweight diagonal fisheye lens specifically designed for Micro Four Thirds sensors. Its build quality is highly impressive, featuring a durable metal mount, a well-damped 8 mm aperture ring that allows for adjustments in 0.5 EV stops, and a smooth 13 mm manual focus ring with a 120-degree throw. Optically, the lens is constructed with 9 elements in 7 groups, incorporating one aspherical and three low-dispersion ED glass elements to help control aberrations. It is available in both black and silver finishes and includes a permanently attached plastic petal-type lens hood. The major advantage of this lens is its mechanical design, which offers better overall build and smoother operation than Samyang's larger APS-C equivalents. However, its extreme miniaturisation introduces several functional drawbacks. The combination of a massive field of view and tiny dimensions makes it incredibly easy for users to accidentally capture their own fingers in the frame. Additionally, because the aperture and focus rings are placed so close together, photographers may prone to accidentally turning both rings simultaneously....

The Samyang 7.5mm f/3.5 UMC Fisheye lens, reviewed on ePHOTOzine, is lauded for its compact, robust construction and exceptional sharpness, offering a 180-degree view at an affordable price. Its UMC coating effectively manages flare, and its light weight makes it a versatile choice for Micro Four Thirds shooters. However, the lens lacks any electronic coupling, requiring manual control of aperture and focus, with no EXIF data transfer. Further limitations include the inability to use screw-in filters, a stiff focusing ring for some, and a bulbous front element, according to the review.

The OpticalLimits Samyang 7.5mm f/3.5 Fisheye Review highlights the lens's strong optical performance tailored for the Micro Four Thirds system. A key pro is its excellent center resolution, which delivers highly sharp images straight from its maximum aperture of f/3.5, with the borders maintaining a very good level of sharpness. Additionally, the lens employs an equisolid (equal area) projection characteristic of standard fisheye lenses, meaning the extreme barrel distortion acts as an intended artistic feature rather than an optical defect. While vignetting data is difficult to isolate due to the nature of the lens, the reviewer notes that the fisheye effect completely overshadows any light fall-off, making vignetting virtually meaningless to the viewer. On the downside, the lens experiences noticeable lateral chromatic aberrations, producing color shadows at the image borders that reach roughly 1.2 pixels in width when shot wide open at f/3.5. These color fringes become even more pronounced in the extreme corners of the frame. Fortunately, this con is mitigated by stopping down the lens to f/5.6 or smaller, which drops chromatic aberrations below 1 pixel and aligns...

The Samyang Rokinon 7.5mm f3.5 Fisheye review by Gordon Laing highlights this budget-friendly lens as a compelling option for Micro Four Thirds system users seeking an ultra-wide perspective without breaking the bank. The reviewer notes that Samyang has built a strong reputation for offering good quality optics at highly affordable prices, with this specific model costing roughly half the price of its competing Panasonic counterpart. Designed to squeeze an impressive 180-degree diagonal field of view into the frame, it stands alongside more expensive alternatives like the original Lumix G 8mm f3.5 and the high-end Olympus 8mm f1.8 in the Micro Four Thirds ecosystem. The primary tradeoffs of this lens are its lack of autofocus and its inability to support auto exposure modes, meaning photographers must be comfortable operating completely manually. However, the review emphasizes that because the focal length is so incredibly wide, these limitations are minor inconveniences that users can easily live without in day-to-day shooting. Ultimately, the review frames the lens as a highly accessible tool for creative photography, delivering excellent structural and optical value for budget-conscious creators.
