Who can introduce Hasselblad, mamia and Lycra and compare them?

These three products are obviously different categories. Hasselblad represents the top medium format technology, and its Hasselblad 5 series and 2 series are widely used by photographers. Professional H3 digital products are the best choice for professional photographers, who mostly use Zeiss lenses. Mamiya, on the other hand, is a relatively cheap medium format product. Mamiya's 67 and 645 cameras used to be a necessary assembly for domestic photo studios, and most of the products used their own brand lenses. For many photographers, Leica's M series paraxial film camera is still a portable camera. Leica is famous for its cutting-edge manufacturing technology, which not only produces M series paraxial cameras, but also produces R series SLR and Leica lenses, telescopes and other products.
