You may or may not find the exact manual for your camera.
That's the bad new. The good news is that a lot of these cameras
have the same features as other cameras. There is a good chance that
you can find a manual here that is very close to what you need -- even if
the extra brand or model name is different from yours. For example,
the manual for the Seagull DF-1 works fine for the Seagull
DF-2.
A few Minolta models are listed because they are exactly the same, or very similar to, some of the Chinese SLR models. For example, the manual for the Minolta X-9 works fine for the Seagull X-9.
Another point to keep in mind is that with many of these models, the translation is obviously muddled, making the instructions difficult to understand -- and some instructions, unfortunately, are incorrect. This may be a problem with translation -- or simply lack of correct information for the translation. For example, the manual for the Kalimar KX 5000 -- which is the same camera as the Seagull DF-99 and the Phoenix P-2000 -- states that the shutter will work without the battery. It will not.
