刚好我才得到一个Weltur69机子，可谓同好。九迷兄可以在这两个链接找到更多介绍。

Welta Weltur
Here's a camera I really like, and like to shoot… whether in 6x9 or 6x6/6x4.5. Ironically, the best ones were made before WW II. They are fitted usually with Compur or Compur-Rapid shutters and usually carry Zeiss Tessars or Triotar lenses, both exceptionally good.
Being a pre-1949 camera it also means that the lenses are uncoated, which is NOT a big concern, especially if you are shooting B&W. But even with color, I noticed no lack of brilliance or contrast… you gotta use a lens hood! In fact, check out the boat picture by the Weltur 6x9 w/ Triotar lens. I enlarged this to 24x30 and hangs in our breakfast room. Really awesome results!
The Weltur cameras are unique in that they have an excellent coupled rangefinder which moves the whole lens assembly to focus, not just the front element. Everyone who has used this camera has praised its design and optics. It is "pre-war German quality" - an easy match for Zeiss or anyone else. Unfortunately, the Welturs were not made after WW II and Welta quality was not quite the same as before.

http://www_camerapedia_org/wiki/Weltur
The Weltur is a series of rangefinder folding cameras using 120 film, made in the 1930s by the German company Welta. The lens is unit focused, driven by a small knob at one side of the folding bed, a system which was already used in the earlier Solida model. The distance setting is visible in a small window on the interior of the folding bed. The rangefinder is coupled, and combined with the viewfinder. There is a depth of field table on the top plate, and a body release.
The Weltur first existed in a 4.5×6 version, with a black finish. Then it was released in 4.5×6, 6×6 and 6×9 versions with a chrome rangefinder, looking like the rangefinder of the first Weltini model. The 6×6 and 6×9 versions are dual format and can also take 4.5×6 pictures, with a mask inserted in the exposure chamber and another slid in front of the viewfinder. They have two red windows on the back.
Lens/shutter combinations:
Weltur 4.5×6 black:
Schneider Radionar 75/2.9 & Compur
Schneider Xenar 75/2.8 & Compur-Rapid
Carl Zeiss Jena Tessar 7.5cm/2.8 & Compur-Rapid
Carl Zeiss Jena Tessar 8cm/2.8 & Compur-Rapid
Weltur 4.5×6 chrome:
Schneider Xenar 7.5cm/2.8 & Compur-Rapid
Weltur 6×6:
Schneider Xenar 75/2.8 & Compur-Rapid
Carl Zeiss Jena Tessar 75/2.8 & Compur
Carl Zeiss Jena Tessar 75/2.8 & Compur-Rapid
Weltur 6×9:
Schneider Xenar 105/3.8 & Compur-Rapid
Carl Zeiss Jena Tessar 10.5cm/4.5 & Compur-Rapid
In all cases, the Compur shutter goes to 1/250 and the Compur-Rapid to 1/400.

http://www_camerapedia_org/wiki/Welta_Solida
The Welta Solida is a combined 6×9cm and 6x4.5cm folding camera released in 1933. It has a coupled rangefinder, separate from the telescopic reverse Galilean viewfinder, in a long rectangular black box. It also has a brilliant finder on the lens standard. The lens is focused by moving the lens panel, driven by a small knob in one side of the folding bed, thus making the camera a mixture of self-erecting folding camera and a folding bed camera. This system was continued in the later Weltur series. The winding is by key, and there is no double exposure prevention. The Solida is dual format, having the ability to take 4.5×6 exposures with a mask inserted in the exposure chamber and a switchable mask built in to the viewfinder.
Known lens/shutter combinations:
Carl Zeiss Jena Tessar 105/4.5 & Compur 250
Carl Zeiss Jena Tessar 105/4.5 & Compur-Rapid 400
Schneider-Kreuznach Radionar f:4.5 F=10.5cm & Compur-Rapid 400
In all cases, the Compur shutter goes to 1/250 and the Compur-Rapid to 1/400.

有几个问题需要注意：
1.不要指望黄斑对焦还准确。由于机构磨损，可能无法校准无限远双影重叠，折衷的办法是把5米左右调校准确，则在3米到15米范围内可以做到基本准确。凑合用就行了。
2.要检查镜头定位可好。Weltur的折叠机构设计得很精巧，大约有14个部件，需要有10个支点的杠杆组来实现支撑和定位（相比之下，军旗820只有6个部件，4个支点），容易出故障，一旦损坏，几乎无法修复。如果支撑臂变软，镜头就会往后退，导致相面定位失准。
3.后背的压片板设计不好，有可能卡住胶卷的衬纸。我还没有找到解决的办法，只有在压片板两端的楞上涂点蜡。
总之，快80岁的老机器了，好好珍惜吧。

想起来，不好意思，该机是某个系列中的一款，还是独此一款。

Royer 6x9 爱展能 100/3.5 X1头.

几个月前应你要求上过几张，在再上一张。

这个头还是真好！

是白头，红窗过片吗？可有用它影的片子？

整组调焦机，黄斑机构是否联动？

再来一张

不要听人说，产品示出是100度就是100度，黑白胶卷的宽容度较大。
