The Hexanon 57 mm / 1:1.4 was introduced shortly after the switch-over to the newer internal linkAR bayonet (1966), as faster alternative to the cheaper standard lens internal linkHexanon 52 mm / 1:1.8. For the older internal linkF bayonet the lens was not yet available, in this mount the internal linkHexanon 52 mm / 1:1.4 was offered as faster alternative, but that lens was not re-introduced in the new AR mount.

The first variation of the Hexanon 57 mm / 1:1.4 did not provide automatic aperture, but was a preset lens. The introduction of automatic aperture with EE setting for automatic exposure followed not long after the lens was introduced.

A short time after the introduction of the internal linkAutoreflex T3 the lens was dropped from the program and superseded by the much better internal linkHexanon AR 50 mm / F1.4, therefore all variations of the Hexanon / Hexanon AR 57 mm / F1.4 still have the splined metal focusing ring.

Image quality is o.k., the Hexanon / Hexanon AR 57 mm / F1.4 renders sharp and contrasty images with neutral colour rendition – results are quite similar to those of the Hexanon / Hexanon AR 52 mm / F1,8 regarding quality. But especially in terms of sharpness, the lens can't keep up with its successor, the first-class internal linkHexanon AR 50 mm / F1.4, you will therefore be served better with that later lens. The differences between the lens generations are a bit smaller than with the slower budget standard lenses, but can still be seen clearly.

The Hexanon / Hexanon AR 57 mm / F1.4 is not very sensitive to stray light. A round metal screw-in lens hood with inner velvet lining was available from Konica as an accessory.

As a slower budget alternative, beside the Hexanon / Hexanon AR 57 mm / F1.4 the internal linkHexanon / Hexanon AR 52 mm / F1.8 was offered first – towards the end of the construction period, with introduction of the Autoreflex T3, the legendary internal linkHexanon AR 50 mm / F1.7 was offered instead.

The difference in speed over the budget standard lens is about 2/3 f-stops – this is nowhere near as important as it used to be in the days when the fastest colour film available was Kodachrome 25. Somtimes, the shallower depth-of-field when used wide open is desirable, especially for portraits. In low-light situations, it still can be the small difference that decides whether or not hand-held images can be made without blur caused by camera shake.

The Hexanon AR 57 mm / F1.4 is much rarer than its slower budget alternative, but can be seen once in a while – it is not a very rare lens. In my opinion, it is only interesting for collectors who look for a historically correct lens for their old camera body. For photography, the successing internal linkHexanon AR 50 mm / F1.4 is better, which in addition is much more common and can therefore be obtained easier and cheapter.
