- Seagull 4 (4·4A·4B·4B1·4C)
Seagull has been producing a series of Twin-lens reflex camera since 1960s and it is believed that they are still producing; the latest model is 4A-109 featuring modern lens coating and some other improvements.
Seagull 4 is the first model from 1967. The predecessor is Shanghai 4.
Seagull 4A is the second model from 1968. Some Chinese amateurs[who?] consider the 4A and the later 4A-1 variants professional, partly because of the very unaffordable prices for most Chinese citizens in 1960s and 1970s, a 4A for 230 RMB and a 4A-1 for 290 RMB, whereas a worker earned only 20 RMB per month. And so to the unavailable to ordinary people, only those working for government and press could can some.
Seagull 4A-1 from 1970s and later 4A-1XX models feature Tessar type lenses. Another noticeable feature is the finally coming hot shoe. The later 4A-1XX models are mainly for selling overseas, hence the absence of Chinese characters is no surprise.
Seagull 4B and 4B-1 are simplified models of 4A. The 4B-1 may take 645 formats. The focus screen of 4B-1 is Fresnel lens achieving bright viewing. Unlike 4A, the original lenses for 4B and 4B-1 are three-element cooke triplet.
As some Chinese vendors are selling proclaimed Tessar lenses components for upgrading old cameras, one may come up with 4B-1 featuring four-element lenses.
Seagull 4C can load 135 films. This model is however very rare.
