Amateur photographer here. For those wondering, this is aimed at a very strange segment. It’s cheap so it seems to go for beginners who want to have different prime (non zooming) options but don’t want the expense. It’s also lighter.

The problems:

• more serious photographers will want better optics and I don’t think this brand is it
• Sharing optics adds complexity to gear in terms of dust/moisture ingress *Cheap prime lenses are not that expensive. This will cost more *You’re better off with a higher quality zoom lens that covers the range of this system
