Extension Bellows II AR
Extension Bellows 2 AR
The Extension Bellows II AR / 2 AR are simple bellows for the newer AR bayonet. The guide consists of a single round gear rack, only the lens plate can be moved, the camera plate is fixed. With a 52 mm standard lens in normal position, a magnification ratio of up to 2.5:1 can be achieved with these bellows. On the gear rack, magnification ratios and exposure compensation values are marked for 52 mm and 135 mm lenses. The lens plate can be clamped in any position on the rack by a respective screw.
As with all Konica bellows, automatic AE exposure is not possible with the Extension Bellows II AR / 2 AR, as there is neither a coupling for the lens's widest aperture nor an aperture actuator mechanism. With the Extension Bellows II AR / 2 AR, the aperture must be closed manually on the lens's aperture ring prior to exposure. The bellows can be combined with the Auto Ring and Double Cable Release, then the automatic closing of the aperture to the value preset on the lens prior to exposure is possible. But as the Auto Ring does add 14 mm additional extension to the system, the values for magnification ratios and exposure compensation marked on the bellows's gear rack will not be correct any longer.
The camera bayonet connection of the Extension Bellows II AR / 2 AR can be turned anti-clockwise by 90°. With the turnable bayonet connection, switching between landscape and portrait images is easy and can be done without having to turn the whole set-up or the bellows themselves.
The lens plate offers no possibility to use the lens in reversed position. If the lens is to be used in reverse position, a Reverse Adapter is required, which was available as a separate accessory.
There is no matching Slide Copier for the Extension Bellows II AR / 2 AR, the bellows do not have a possibility to couple to it.
An 1/4" tripod socket is placed in the bottom of both lens and camera plate of the Extension Bellows II AR / 2 AR.
The Extension Bellows II AR / 2 AR were introduced shortly after the new AR bayonet had been established. As a better equipped alternative, the Extension Bellows II Deluxe AR / 2D AR were sold contemporarily. During the time of the Autoreflex T2, both bellows were replaced by their successor models Bellows 3 AR and Auto Bellows AR.
The Extension Bellows II AR / 2 AR are quite rare and show up only once in a while. Third-party bellows are easier to find and just as cheap, while they frequently offer more possibilities than these very simple bellows.
Accessories for Extension Bellows II AR / 2 AR
Allows for reverse position of lenses with a 55 mm filter thread without having to turn the lens plate of the bellows.
Auto Ring with Double Cable Release
An extension ring with a built-in mechanism for closing the aperture when tripping the shutter release by aid of a double cable release. It is not needed on the Auto Bellows AR, as the bellows themselves offer the respective functionality. The use of the Auto Ring with the Auto Bellows AR only makes sense when the lens is mounted in reverse position with a reverse adapter.
Bellows adapter 57mm F1.2
The extremely fast lens Hexanon AR 57 mm / F1.2 does not have the 55 mm filter thread as do most Konica lenses. For this reason, the Reverse Adapter does not fit that lens. With this adapter, lenses with a 62 mm filter thread can be used in reverse position on bellows. On Extension Bellows II AR / 2 AR and Extension Bellows 2D AR you will also need the reverse adapter.
