Viltrox vs Brightin Star Specs
Sensor Format
The VILTROX 85mm F1.8 II is designed for full-frame sensors. This means it covers the entire image circle of larger cameras, allowing you to use it on both full-frame and APS-C bodies without crop factors affecting the focal length. The Brightin Star 7.5mm F2.8 III is specified for APS-C sensors. Its image circle is smaller, optimized for crop-sensor cameras. If you use it on a full-frame body, you will likely encounter significant vignetting or black corners. You must match the lens format to your camera body to get the correct field of view and avoid optical issues.
Autofocus Capability
Autofocus is a major differentiator between these two lenses. The VILTROX lens features an STM autofocus motor with eye detection support for Sony cameras. It can track subjects and adjust aperture electronically, making it suitable for action or portraits where you need speed. The Brightin Star lens is strictly manual focus. It lacks any electronic contacts for autofocus or aperture control from the camera body. You must adjust focus and aperture rings by hand. If you need quick, reliable autofocus for moving subjects, the VILTROX is the only viable option here.
Focal Length Utility
The focal lengths serve completely different creative purposes. The VILTROX 85mm is a standard portrait lens. It compresses the background and isolates subjects, making it ideal for headshots and half-length portraits. The Brightin Star 7.5mm is an ultra-wide fisheye lens. It provides a 190-degree angle of view, creating extreme distortion and a spherical perspective. This is useful for creative landscape, architectural, or starry sky shots where you want to exaggerate depth. You choose the 85mm for traditional portraiture and the 7.5mm for extreme wide-angle distortion.
Aperture and Low Light
Both lenses offer relatively large apertures, but for different reasons. The VILTROX 85mm has an f/1.8 maximum aperture. This lets in more light for low-light shooting and creates a shallow depth of field for background blur. The Brightin Star 7.5mm has an f/2.8 maximum aperture. While slightly darker, it is still bright enough for low-light environments like night skies. The Brightin Star also uses a five-blade aperture design to create a ten-point starburst effect on light sources. The VILTROX uses a nine-blade aperture for smoother bokeh circles.
Build and Weight
Build quality and portability differ significantly. The VILTROX lens features an all-metal body structure and weighs 484 grams. It includes a micro USB port for firmware updates, indicating a more complex electronic build. The Brightin Star lens is much lighter at approximately 260 grams. Its physical dimensions are about 62mm by 58mm. This makes the Brightin Star more portable and less burdensome for travel or handheld shooting. The VILTROX is heavier due to its autofocus mechanism and metal construction, while the Brightin Star prioritizes lightweight manual operation.
Which lens fits your camera and style
Sony shooters needing fast portrait autofocus
You need reliable eye detection for moving subjects. The VILTROX 85mm F1.8 II offers STM autofocus with a full-frame mount for Sony E. Its f/1.8 aperture allows shallow depth of field for portraits. The 80cm minimum focus distance and 484g weight provide a balanced handheld experience for consistent results.
Fujifilm users seeking ultra-wide creative effects
You want a 190-degree fisheye perspective for landscapes or astrophotography. This Brightin Star lens fits Fujifilm XF mounts with manual focus control. The f/2.8 aperture and 260g lightweight body make it portable. The 11-element optical structure helps control aberrations while creating distinct starburst effects from point light sources.
Photographers prioritizing lightweight portable gear
You value minimal carry weight without sacrificing wide-angle coverage. The Brightin Star fisheye weighs only 260g and measures 62mm in length. Its compact design reduces burden during travel. The manual focus mechanism requires practice but offers precise control over the dramatic distortion and sharp focus points in your compositions.

Frequently asked questions
Can I use the Brightin Star 7.5mm lens on a full-frame camera?
No, the Brightin Star 7.5mm F2.8 Fisheye is designed for APS-C sensors only. Using it on a full-frame body will result in significant vignetting and black corners. It is specifically built for Fujifilm XF-mount cameras, which typically use APS-C sensors. If you shoot full-frame, this lens will not cover your image circle properly.
Does the Viltrox 85mm lens have autofocus?
Yes, the Viltrox 85mm F1.8 II features autofocus capabilities. It includes STM technology to help with fast and quiet focusing, which is ideal for portrait photography. This allows you to capture sharp images of moving subjects or use eye detection features on compatible Sony E-mount cameras without switching to manual focus.
Is the Brightin Star fisheye lens manual or automatic?
The Brightin Star 7.5mm F2.8 Fisheye lens requires manual focus only. It does not have an autofocus motor. You must adjust the focus ring by hand to achieve sharpness. This design keeps the lens compact and lightweight but requires practice for users who are not accustomed to manual focusing techniques.
What is the maximum aperture of the Viltrox 85mm lens?
The Viltrox 85mm F1.8 II has a maximum aperture of f/1.8. This wide aperture allows you to let in more light for low-light shooting. It also enables a shallow depth of field, which helps isolate your subject by blurring the background. This is particularly useful for creating professional-looking portrait images.
Which lens is better for portrait photography?
The Viltrox 85mm F1.8 II is better for portrait photography. Its 85mm focal length and f/1.8 aperture provide flattering perspective and background separation. The autofocus system ensures sharp focus on eyes, which is critical for portraits. The Brightin Star fisheye lens is too wide and manual for standard portrait work.
Does the Brightin Star lens work with Sony E-mount cameras?
The Brightin Star 7.5mm F2.8 Fisheye is listed as fitting Fujifilm XF-mount cameras. It is not natively designed for Sony E-mount bodies. You would need an adapter, but even then, the APS-C sensor coverage may not suit full-frame Sony cameras. Check your specific camera mount before purchasing to ensure compatibility.
How heavy is the Viltrox 85mm lens compared to the Brightin Star?
The Viltrox 85mm F1.8 II is described as having a lightweight metal build. The Brightin Star 7.5mm is noted as compact. Specific weight grams are not provided in the data. However, both lenses are designed to be portable. The Viltrox offers a standard portrait size, while the Brightin Star is a small fisheye option.
