The Revue 400SE is manufactured by Minolta (OEM'd by Cosina in most cases) for Revue of Europe and is indeed a Minolta Hi-matic 7s-II clone-- well, almost. The main difference is that the 400SE is shutter priority only, which to my mind actually makes more sense since the aperture ring on the 7s-II is so damn small, no one ends up using it anyway--at least I don't--and it only clutters up the interface. The 400SE, unlike it's 7s-II cousin, has a Guide Flash Control and a PC connector *as well as* a hot-shoe.
Also unlike the 7s-II, the 400SE has Guide Numbers marked "LZ" (Leitzahl = guide number in German) for flash automation. If you fire a flash at full power, you can calculate depending on the LZ/GN and aperture the distance where the light is optimal. If you know the distance (and the camera does from the rangefinder) and the LZ/GN (which you can set), you know the aperture - and the camera sets it automatically. So if you have a non-automatic flash, just dial in the LZ/GN (in meters), focus and get perfectly illuminated shots. A nice feature, which provides results better than some TTL flashes. And the camera can sync at any speed, enabling daylight fill flash at shutter speeds of up to 1/500 sec!
That may have been more info than you needed--certainly more than you asked for--so take it for what it's worth. Happy shooting.
