If you're aching to go back in time to when people frequently shot with medium format film, the Seagull 4A-109 is for you.
Here's the scoop from dealtime.com: "The Seagull 4A-109 is the top of the Seagull medium format roster. This non-metered classically-styled twin-lens reflex camera is patterned in the time-honored design of older Yashicamats.
Its lightweight simple design consists of a waist-level finder with pop-up magnifier, manual film crank advance and separate shutter speed and aperture levers.
The 4A-109 has all the features of the GC-107 and includes a 4 element "picture taking lens" plus a shutter lock lever.
The viewing lens is a 75mm f/2.8 lens made of 3 elements in 3 groups. The mechanical lens shutter design provides flash synchronization at all speeds up to 1/500 second and there is also Bulb exposure.
This camera also features a cold flash shoe and PC terminal for external electronic flash connection."
