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??
