Brightin Star Announces the MF 14mm F2.8 Wide Angle Lens

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??

I'm still chugging along with my Bower EF mount 14/2.8 which has 14 elements in 12 groups. A different optical design, of course, given that the lens is designed for EF. As often as I use it, which is almost never, I'm fine with what I have.

It'll be interesting to see what this Brightin Star/7Artisan/Pergear lens is like compared to the EF 14/2.8. Price and feature-wise, they're in the same ballpark.

I'm happy to learn about this stuff. I can't dive deep into everything. For me, Brightin Star are just nice people. These don't sell like hotcakes, there really isn't a revenue stream. I tend to promote the nice ones.

I might dive a bit deeper down the road. I have enjoyed their 50 f/1 and 9mm 5.6. not claiming optical excellence!
