Sorry, but that isn't a new lens! That is just a known lens with a different label!
I saw it first as a Pergear 14/2.8 lens, afterwards as 7Artisan 14/2.8 (with a different desgin of the lens barrel) and now as Brightin Star 14/2.8. The optical construction - 13 elemenst in 9 groups - and the special glass elements are always the same. I have the Pergear 14/2.8 and the 7Artisan 14/2.8 (for astro photography) and don't see any difference. The optical quality is good (low coma for astro!), but the vignette is a little bit high. There is a more in-depth review of the Pergear 14/2.8 by phillipreeve.
It would be interesting to understand the structure behind these 'different' brands! Is it just one company which is just moving the lenses around from A to B to C or what??
Typical chinese, right!!!
This is a standard practice in the budget Chinese lens market. A core optical design originates from one or a small group of factories and design houses in China. Various marketing outfits and brands then slap their name on it. They adjust the barrel cosmetics, tweak the focus ring feel, or add minor changes such as aperture de-clicking. After that they push the product through their own sales channels.
Pergear released an early version around 2022-2023, followed by a Mark II. 7Artisans brought out their take later, near 2025, with different barrel styling but matching optics. Brightin Star, operating as Shenzhen Yinyao Technology, now sells it alongside other rebadges like Cheecar.
These companies position themselves as designers or assemblers with factory capabilities. Yet the identical MTF curves, element arrangements, and field performance across the lineup make it clear they share the same underlying product. It is not a single firm simply moving stock. Instead it forms a tight network of manufacturers and marketers that spreads distribution as wide as possible. The system holds costs down and reaches more customers. At the same time it muddies the water for buyers and weakens any real brand distinction. Quality control can differ from batch to batch. Overall it stays in line with the rest of the low-cost manual lens segment.
For Canon RF users chasing astro or landscape work these ultra-wides offer basic value at entry prices around $240. Edge-to-edge sharpness wide open will not rival premium optics, and vignetting remains noticeable. Stopped down they deliver acceptable results for the outlay. If existing copies already perform adequately, another version brings no meaningful optical gain, only fresh cosmetics and marketing.
Budget ultra-wides put accessibility first and perfection a distant second. The whole approach reflects how these Chinese operations routinely operate.
