  1. Elements, groups, angle of view, minimum aperture, closest focus, magnification, filter size, dimensions and weight are the maker's own figures, identical in the 1995 Mamiya 7 manual (p. 27) and the Mamiya 7 II lens manual (p. 13), both hosted at butkus.org.
  2. Camera-wiki gives the 65 as 8 elements in 5 groups. Both Mamiya manuals and the Japanese Wikipedia product list say 9 elements in 5 groups, and the manual's cross-section shows nine; the maker's figure is used.
  3. The 1995 date is the camera's; the lens is in the launch manual, and no source gives a separate lens release date. The 2014 end date is Wikipedia's for the Mamiya 7 system as a whole.
How to tell them apart (expand)
  • One optical version only, sold from the 1995 launch to the end of the system; a lens marked N 65mm f/4 L fits the Mamiya 7 and the 7 II alike
  • Not to be confused with Mamiya's other 65s: the RB67 and RZ67 65mm lenses (Sekor C f/4.5, Sekor Z f/4, L-A), the Press/Universal 65mm f/6.3 and the TLR 65mm f/3.5 are different lenses on different mounts
  • The 58 mm filter thread is shared with the 80mm and 210mm; the 43, 50 and 150 take 67 mm

Mamiya N 65mm f/4 L (single version, 1995–2014):

  • Engraved N 65mm f/4 L on the front ring; black barrel 65 mm long by 67 mm across, 380 g, 58 mm filter thread, bayonet hood supplied (Mamiya 7 manual, p. 27)
  • Aperture ring 4–22, rangefinder coupling lever, distance scale in m and ft, infrared index, depth-of-field scale; the body's finder shows the 65mm bright frame automatically (Mamiya 7 II lens manual)
  • The 65 frame is also what the body shows when the 43 or 50 is mounted, so a 65 frame in the finder does not by itself mean a 65 is fitted (Mamiya 7 II lens manual, p. 5)

History

The N 65mm f/4 L is the moderate wide-angle of the Mamiya 7 system, a 69° lens that Mamiya’s manual equates to 32mm on 35mm film, and the lens most often sold with a body. It was one of the four lenses in the 1995 instruction book (“Wide angle: 65mm f/4 L”) beside the 43, 80 and 150, and its figures did not change through the 7 II years: 9 elements in 5 groups, f/4 to f/22, closest focus 1 m at 0.078× (a field of 719 × 892 mm), a 58 mm filter thread, a bayonet hood supplied in the box, 65 mm long by 67 mm across, and 380 g. The 1995 manual prints a cross-section, a thick front group in front of a smaller symmetrical rear, which is linked below rather than reproduced.

One count is disputed. Camera-wiki gives 8 elements in 5 groups; both Mamiya manuals and the Japanese Wikipedia product list say 9 in 5, and the cross-section shows nine, so the maker’s figure stands here. There is otherwise one version. The Mamiya 7 of June 1995 and the 7 II of January 1999 share the mount and the whole lens line, and the 7 II changed the body (a tinted bright-frame finder, multiple exposure, a second strap lug), not the glass. Every Mamiya 7 lens carries its own #00 electronic leaf shutter, timed by the camera: 4 s to 1/500 and B, flash sync at every speed, and no exposure at all without the body’s 6 V battery. Wikipedia gives 2014 as the end of the system. No serial ranges, production figures or list prices were found.

The 65 is inside the body’s finder, which brings up its bright frame automatically and corrects parallax as the lens focuses; the same 65 frame is what the finder shows when a 43 or 50 is mounted, which is why the 43’s external finder is needed. Reviewers treat the 65 as the everyday lens. Michael Nguyen at Japan Camera Hunter calls it the kit lens and points out that it is wider than the 80mm standards most medium-format cameras ship with; Jake Bryant used a 7 II with only the 65 for years and calls it “truly a great combination” and “wonderful for landscapes”; Andrew on 35mmc ended up shooting his colour work on it after his 80 arrived with severe balsam separation. Nguyen’s reservation is a matter of taste: the Mamiya lenses are sharp and great, but he prefers the character of the Makina’s Nikkor.

What to check when buying: the gold-plated contacts on the rear mount, since aperture and shutter are driven electronically and a dirty contact stops the exposure; that the shutter fires at every speed on a body with a fresh battery; the glass against a bright light for haze and balsam separation, which Andrew reports on the 80 and warns is common; that the bayonet hood and rear cap are present; and the barrel itself, which is light and partly plastic, the standing complaint about Mamiya 7 lenses set against glass that nobody complains about. What remains open: the designer, the month it shipped, its price, and how many were made.
