Auch das Minolta 4/135mm gab es in drei Versionen, einmal mit Fokusschnecke und zweimal ohne - für die Nutzung am Balgengerät:

ZITATMINOLTA 135mm f3.5 & f4.0 LENSES
[...]
From the earliest days, Minolta made several 135mm lenses targeting the lower-priced market. Initially, these appeared with a f4.0 optic, but later evolved into a f3.5 lens. These should not be construed as lower quality lenses just because they are lower priced. Like the 28mm f3.5 lenses, the 135mm f3.5 and f4.0 lenses were designed to cut cost, not quality.
The competition
There are several 135mm lenses with a f3.5 aperture. Most are these are very inexpensive, thanks to poor workmanship, with poor results.[/quote]

COMMENT
A less expensive alternative to the 135mm Auto-Rokkor, but don't assume this lens is a slouch. It's 12 blade aperture tells you that Minolta didn't cut any corners in quality.[/quote]

ZITATMINOLTA 100mm & 135mm BELLOWS LENSES
[...]
Bellows lenses are sometimes referred to as short-mount lenses since the part of the lens barrel that focuses the lens is removed. It's not needed since these lenses are designed to be used on a bellows -- and the bellows does the "focusing". This keeps the lenses small, light and less expensive -- BUT, you have to have a bellows. Fortunately, these are not expensive, but they are more difficult to use than a typical lens.
Unlike many SLR manufacturers, Minolta always had a commitment to close-up photography, and sold a wide range of lenses designed for use on a bellows and for macro- and micro-photography. Minolta made bellows lenses in five focal lengths:
* 12.5mm
* 25mm
* 50mm
* 100mm
* 135mm
At one end of the spectrum are the 100mm and 135mm lenses. These were the first bellows lens made by Minolta and are considered the standard by which the other bellows lenses are measured. The first bellows lenses were designed to be able to focus to infinity. This is useful under some circumstances, but most people use a bellows for macro-photographic purposes -- focusing to infinity is the last thing on their mind. These lenses will focus to 1:1, AKA (Also Known As) 1X or life-size -- or closer, depending on the amount of extension on the bellows. Some even have automatic diaphragms which was a breakthough in bellows operations, but you'll need an automatic bellows to utilize this feature. Minolta later added shorter focal length lenses to their line-up to get even higher magnifications!
Minolta also made a wide variety of enlarging lenses that make excellent bellows lenses with the correct adapter. In addition, Minolta made macro lenses in 50mm and 100mm lenses which allow close-up photograhy WITHOUT a bellows, but if you want to get REALLY close, you need a bellows and a bellows lens![/quote]

COMMENTS
Minolta's first short-mount lens (i.e., designed for use on a bellows), it has a Leica thread (39mm) and was supplied with a Leica-to-Minolta adapter. Why a Leica thread? Minolta knew that sales of a specialty lens, such as this, would be relatively low. By supplying it with a Leica thread, users of other cameras (not just Minolta and Leica) could adapt it to their particular camera. The lens was not, as some suggest, designed, nor maufactured by -- or for -- Leica. The lens is, in fact, the Minolta 135mm f4.0 Rokkor with the focusing mount removed. Consequently, for close-up work the results are not as good as might be expected with a bellows lens, since the lens is not a flat-field optic.[/quote]
Nicht ganz eindeutig geht aus dem Text hervor, ob es sich bei dem Adapter um den dünnen Minolta "L adapter" (Leica-to-Minolta adapter) handelt oder um den Minolta "M adapter", der 20mm Auszug aufweist. Beide Adapter adaptieren vom Leica M39-Gewinde auf das Minolta SR-Bajonett und bei beiden Adaptern stimmt das Auflagemaß nicht, so daß mit normalen Objektiven keine Fokussierung auf Unendlich möglich ist.
