Taihu 4型

The Taihu 4型 is a medium format TLR camera introduced by Taihu in 1978, utilizing 120 film and equipped with a simple shutter offering B (bulb) setting and speeds from 1 second to 1/300. As a TLR, it features two lenses - one for viewing and focusing, and one for taking the actual photograph - a design that provides a waist-level viewfinder image but no focusing screen. This appears to be a straightforward, functional camera aimed at general photography enthusiasts rather than professionals or specialized applications, typical of many TLR models from the mid-to-late 20th century that followed the established pattern of more prestigious predecessors.
