Minolta Minolta 55mm f1.7 Heritage

Overview

The Minolta MC Rokkor 1:1.7 55mm is a normal lens with a lineage stretching back decades. According to phillipreeve.net, Minolta made two very similar versions: the first introduced in 1966 with a flat focusing ring, and a second introduced in 1970 with a 'hill/valley' type focusing ring. Both versions came with and without a stop-down lever. The lens described in the review is roughly 50 years old, making it a product of Minolta's classic SR-mount era. The reviewer names it one of his favorite normal lenses to use on the Sony a7, citing exceptional build quality made from nothing but glass and metal with very low tolerances, better in his opinion than the $1000 Sony FE 1.8/55. No nicknames or community jargon are evidenced in the reviews, so none are claimed here. Its cult appeal comes from being an inexpensive (around $30-40 on eBay), superbly built, well-handling classic normal lens that adapts well to mirrorless cameras. Note: this profile is based on the MC 1.7/55; the review does not cover an MD-mount 55mm f/1.7 specifically.

Verdict: Based strictly on the available reviews, the Minolta MC Rokkor 1.7/55 is a superbly built, compact, and inexpensive classic normal lens that is a favorite for adapting to mirrorless cameras. Its detailed optical rendering is not documented in these reviews, but its exceptional metal-and-glass construction, pleasant handling, and low price make it an easy recommendation for anyone wanting a well-made vintage fifty-ish normal lens on a Sony a7 or similar. Note the provided reviews cover the MC (SR-mount) version rather than a specifically MD-mount 55mm f/1.7.

Community Insights

What people love

Outstanding build quality made entirely of glass and metal with very low tolerances, engraved numbers, and minimal wear even after heavy use; the reviewer says it is built better than the $1000 Sony FE 1.8/55
Small, light, and well-balanced on both the Sony a7 and the smaller Nex-5n
A focus throw the reviewer describes as 'just right' for both portraits and landscapes (about 80° from 55cm to 1m, plus a further 45° to infinity)
The metal aperture ring has perfect resistance and distinctive stops
Non-rotating filter thread, which makes using polarizers easier
Very affordable, typically selling for around $30-40 on eBay
Adapts very well to mirrorless mounts (Sony E, Fuji-X, Micro Four Thirds, Samsung NX)

What people dislike

There is no aperture stop between f/1.7 and f/2.8, making it hard to set an intermediate aperture
The 55cm close focusing distance is a bit high compared to most normal lenses that focus to 45cm (only partially compensated by the longer focal length)
The unusual 52mm filter thread, which differs from the more standard 55mm thread found on most Minolta lenses from about 1968 onward
Cannot be used well on DSLRs due to Minolta SR flange focal distance; adapters need corrective optics that hurt image quality or you lose infinity focus

Pro Tips

Use it on a full-frame mirrorless body like the Sony a7 for best results, though it also gives nice results on APS-C bodies like the Nex-5n
Avoid DSLR adapters entirely; use a simple mirrorless adapter (Sony E, Fuji-X, MFT, Samsung NX) to keep image quality and infinity focus
Take advantage of the non-rotating filter thread when using polarizers
Be aware there is no intermediate stop between f/1.7 and f/2.8 when setting exposure
