To turn the aperture ring on the original 55/1.8 PF Rokkor, you had to depress a chrome latch. The left pic shows the chrome latch at the rear of the lens near the lens mount. Its knurled edge is barely visible to the right, opposite the FP sync marking. Separate PC connections were used for flashbulbs (FP) and electronic flash (X). The large knurled chrome button is the lens release, a design which lived on to the last of the mechanical Minoltas, the SRT-202.

OK Minolta Super Fans, What is that little black hole for on the bottom plate?? I am fairly sure it is the anchor point of Minolta's announced, but never produced, SR-2 electric motor drive.That's right Minolta fans, the SR-2 announced the availability of a motor before the Nikon F! Unfortunately it was an awkward design, similar to the Alpa, that did not have an internal connection. Instead, a complicated mechanism manipulated the lever advance and normal shutter release! You guessed it. Once Minolta saw Nikon's much more advanced motor which did make it to production, Minolta quietly shelved production of its motor. A good thing too. Later the motor, or at least a version for it, was produced for professional use in very limited quantities for the SR-3.

SR-2 Cases are not easy to find today. They were well made, heavy duty leather cases with metal trim.

Black SR2? Does anyone know of a black SR-2? If you do, please email me the serial #.

Serial Numbers: If there is a definitive list for SR-2 serial numbers, as well as the early SR lenses, please direct me to it. In any case, accurate information seems to be lacking in English. So, I am collecting serial numbers of the SR-2, SR-1, SR-3 in an effort to determine production figures. Please email me. Eventually the results will be posted here.

Family portrait of early Rokkors: left to right: 35/2.8, 135/4, 55/1.8, 100-200/5.6, 100/3.5.

Minolta's 1st SLR wide angle, the 35/2.8 Auto Rokkor HG. This is a rather large lens for its focal length and f/stop, weighing in at 10 1/2 oz. This lens has a 55mm filter size, close focus distance a commendably close 9 inches. You could not change f/stops without pushing in a chrome lever at the rear of the lens. Clicked marked at full f/stops.

Though not one of the earliest lenses, the economy priced 35/4 pre-set Rokkor has been forgotten by many Minoltaites. It remains one of Minolta's first attempts at low priced SLR lenses. Early SR lens cases are kind of plain. If you look very carefully in the center of case top, at what seems to be at first glance an insignia of some sort, you can read a styled 'Minolta.'

Minolta's 1st SLR portrait lens, the 100/3.5 Auto Tele Rokkor QE. This is a rather large lens for its focal length and f/stop, weighing in at 11 1/2 oz. This lens has a 55mm filter size, close focus distance about 3 1/2 feet. You could not change f/stops without pushing in a chrome lever at the rear of the lens. Clicked marked at full f/stops.

Initially Minolta's longest SLR focal length, the pre-set 135/4 Rokkor TC which was the low budget companion to the earlier 135/2.8 pre-set. This is a rather large lens for its focal length and f/stop, weighing in at 13 1/2 oz. This lens has a 48 mm filter size, close focus distance just under five feet.

The illustrious 100-200/5.6 Pre-Set Zoom Rokkor.

.

As the zoom zoomed to 200mm, the lens gained 38mm in length. Close focus was a none-too-macro 7.75 feet. Filter size is 52mm. This is a pre-set lens. The photog had to manually turn the aperture to the pre-set f/stop to take the picture, and then manually open up the lens again to focus. Not one of Minolta's more elaborate designs, this simply engineered and finished 100-200 Rokkor zoom looks much more like it came from the mind of Soligor or Vivitar than Minolta. hmmmm.

The SR-2's instruction book shows the 35/2.8, 100/3.5, 135/2.8, 200/3.5, 600/5.6, Microscope Adapter, Polarizing Filter, Angle finder, Bellows, Focusing Magnifier, Extension tubes, Flash, and Copy Stand.

The SR-1 followed in 1959. It was a less expensive SR-2 with a 1/500th top speed and a slower 55/2 lens, being modified over time in five different variations. The first versions had the semi-automatic diaphragm of the SR-2. The 1962 version was updated with an automatic diaphragm. Eventually it had a different body style, 1/1000th top speed, and depth of field preview on the lenses) with the SR-1s of 1964. Late versions got rid of SR-2 style top plate terraces, replaced with squared body styling.

The SR-3 replaced SR-2 in 1960, basically a SR-2 with accessory clip for an add on selenium meter. It introduced Minolta's automatic diaphragm.

The SR-7 of 1962 looked much like the SR-3 that it replaced, but made history by being the first still camera with built in CDS metering (not TTL). One nicety was mirror lock up. 1962 version had top plate terraces like the original SR-2. 1964 version got rid of the terraces with squared body styling which carried over to the SRT-101.

Sony camera serial numbers

The famous and very successful SRT-101 was introduced in 1966 with TTL metering, MC Rokkor lenses, and self indexing lens to meter coupling. It's worth mentioning that Nikon's 1977 AI coupling is for all intents and purposes a copy of the Minolta SRT-101 MC meter coupling. Minolta was never really in the first ranks of SLR makers until the SRT-101 which set new standards of excellence for Minolta. It remains of the best mechanical SLRs ever.

The SR system steadily grew from its introduction in 1958, but was always a quality amateur camera without the extensive professional system capabilities necessary to capture most Pro's hearts and pocket books. This changed in 1973 with the introduction of the professional XK and XK motor. Alas, pros did not trade in their Nikons and Canons for the XK. It was eventually discontinued -- without a replacement. Even today Minolta remains a very capable system fully capable of professional results, but it is still a notch behind the likes of Nikon and Canon with a smaller system and fewer lenses. The new Dynax aka Maxxum 9 introduced in the Spring of 1999 aims at the pro's heart and pocketbook. The 9's abundance of features, some of which are not matched by Nikon and Canon, means that Minolta finally has a pro camera fully capable of going against the best from Nikon and Canon. Time will tell if Minolta's new visit to the Pro ranks is a success.
