Mamiya 7II review

General

Mamiya 7II, the successor to Mamiya 6 and 7, is a medium format (6X7) rangefinder camera. It boasts interchangeable lenses with leaf shutters and features automatic parallax correction, aperture-priority auto-exposure, exposure correction, multiple exposure mechanism, as well as... a self-timer (6X7cm snapshots, anyone?). The camera has very few controls and no frills, which allows one to concentrate on photographic subject matter. Most importantly, it produces huge slides (or negatives) of astounding quality. That said, Mamiya unfortunately made a couple of controversial design decisions which turned the camera into a very specialized tool and significantly limited its potentially wide range of applications.

Built quality, ergonomics and handling

If you are used to Hasselblad or Nikon/Canon top-of-the-line equipment, you are certain to find the built quality of the Mamiya 7II somewhat unsatisfactory. Does this mean that the camera is not reliable and is likely to fall apart on you? I do not think so. My experience and overall impression have been that if one sets aside such metaphysical concepts as "plasticy" etc., the camera appears fully dependable in the field.

Generally, it is fairly intuitive to use, very comfortable to hold and handles quite well. Film loading (the camera takes both 120 and 220 film) is very easy and I found it only marginally slower than with a 35mm camera. However, some design details could certainly be improved. For instance, I find the lens release bottom too rough and unergonomic. As another example, light shield curtain closing lever handle is plastic and bends slightly when used (it is unlikely to break yet does not inspire confidence either; there is the same problem with the film speed dial). As another illustration, back cover is not very easy to open. And as yet another case in point, power on/off lever is designed in such a way that if you are not careful it is easy to accidentally trigger shutter release (which, by the way, is a hair-trigger) when switching the camera on or off.

Mamiya 7II is very light considering the huge 6X7 slides that it delivers. The camera with a lens is actually lighter than a top-of-the-line Nikon/Canon body with a zoom lens. This, obviously, is a great benefit and perfect for situations when weight is of a major concern. However, the camera is quite bulky. It takes quite a lot of space in your bag unless you remove the lens; also, it is big (and strange-looking) enough to constantly draw other people's attention in the street. For one thing, I feel less vulnerable when doing street photography with a Nikon (D)SLR.

Lenses

There are six lenses available for the camera - 43mm f/4.5, 50mm f/4.5, 65mm f/4.0, 80mm f/4.0, 150mm f/4.5 and 210mm f/8 (respectively equivalent to 21mm, 25mm, 32mm, 40mm, 75mm and 105mm in 35mm format). Most photographers, however, seem to settle down to a three-lens kit either choosing a combination of 40mm, 65mm and 150mm lenses or, alternatively, deciding to use the 50mm, 80mm and 150mm set.

All lenses boast built-in electronic leaf shutters, come with bayonet mount lens hoods made of cheap plastic and are nearly perfect in terms of optical quality - they are very sharp (in fact among the sharpest in the medium format), free from distortion and flare and show no visible light fall-off even at maximum apertures.

Only three lenses can be effectively used without external viewfinders - 65mm, 80mm and 150mm; there is an optional viewfinder for the last-mentioned yet most users report that it is not really needed. Viewfinder frame is automatically indexed upon lens interchange. The rest of the lenses need external viewfinders which are attached to the camera's flash shoe and used for composition only (metering and focusing are still done using the camera's viewfinder). Most users find using one viewfinder for metering and focusing and a separate viewfinder for composition quite cumbersome.

The 210mm lens is a strange beast. Its minimal focusing distance is seven (!) meters; its maximum aperture is f/8; it is not coupled with the camera's rangefinder and is focused by guessing the distance. Obviously, these factors significantly limit its possible applications.

Metering and auto-exposure

Mamiya 7II features a built in meter in a form of a simple SPD sell. It is of a center-weighted pattern (with the 80mm lens) and located behind a window on the camera body. This, obviously, has two implications. First, it is not a TTL (through-the-lens) meter, which means that you need to take special care (adjust exposure) when using filters. Second, the meter has a constant angle of view, which in effect changes its pattern when lenses of different focal lengths are used - it has a center-weighted pattern with the 80mm lens, a roughly averaging pattern with the 150 lens, and becomes almost a spot meter with the 43mm lens. I have to also note that the actual area metered is not specified anywhere and can be established only through testing and extensive experience.

Very naturally, one would want to know how accurate/reliable the meter is. The answer is very simple, really - it behaves exactly as meters of the above-mentioned patterns do. To be more concrete, though, one needs to always keep in mind two factors when using the meter - namely, a lens' focal length and a scene's contrast and overall tonality. On the one hand, the meter is very easy to use when photographing low-contrast scenes with the lenses of longer focal lengths, in which case you can use the camera as a point-and-shoot. On the other hand, it is quite difficult to employ when photographing high-contrast scenes with wide-angle lenses (in this case you have to apply the good old zone system). And of course, there are all kinds of situations that fall between these two extremes.

To be able to cope with different lighting conditions, the camera offers two auto-exposure modes - aperture-priority auto-exposure (AE) and AE lock. The former simply meters whatever the camera is pointed at and sets the shutter speed in 1/6 increments (the viewfinder display only shows shutter speeds in full stops - more on this below). The latter does the same but locks the shutter speed when the shutter release is half-depressed to allow you to recompose. I tend to use the camera in AEL mode most of the time.

The camera in manual mode

The camera was designed to be primarily used for handheld photography in aperture-priority auto-exposure mode. This is exactly the reason why the viewfinder display shows shutter speeds only - you choose and set the aperture manually and the camera sets the shutter speed. This also explains why shutter speeds are shown in full stops only in spite of the fact that they are set by the camera in virtually stepless manner - they are displayed to let you roughly estimate whether the shutter speed chosen by the camera is fast enough to shoot handholding.

If you want to set exposure manually (read to use the camera on a tripod), the Mamiya 7II is crippled. The problem is that in manual mode shutter speeds can only be set in full stops and the aperture ring is equipped with full stop clicks only (it is possible to set the aperture in between full stops but this is very imprecise). Due to this, it is very difficult to exercise precise control over exposure and the camera is not suitable to shoot slide film in manual mode (this is not a big problem if you shoot negative film, though).

What Mamiya engineers should have done is enable exposure-compensation (in 1/3 stops) to be used in manual mode, too, which would have allowed one to fine-tune exposure up to 1/3 of a stop. Or at the very least, all lenses should have been equipped with half-stop clicks. Had this been implemented, the camera would have become a great choice for a far wider range of photographic genres including landscape.

Other drawbacks and advantages

The camera offers all the benefits which are usually associated with the rangefinder design and leaf shutters:

  • The shutter is very, very quiet - to the extent that I personally find it way too quiet. It gets difficult to hear whether the shutter has been triggered when photographing in noisy streets or near waterfalls.

  • There is no mirror box. On the one hand, this means that there is no mirror slap and sharp results can be obtained hand-holding the camera at slower-than-usual shutter speeds. On the other hand, the rear element of a lens can get as close to the film plane as necessary, which makes correcting for lens aberrations much easier (hence the outstanding optical quality of all the lenses). And of course, overall design of the camera is lighter and more compact.

  • Flash synch at all shutter speeds (i.e. up to and including 1/500).

Among other advantages I would note that I personally adore the near-square 6X7 format and find it the best for composition.

Likewise, the camera inevitably has all the drawbacks inherent in rangefinder cameras:

  • No depth-of-field preview - I am sure you know what that means.

  • Very imprecise framing - when a lens is focused at infinity, the camera captures 18% more than what viewfinder frame indicates. That said, with experience one learns to estimate what is going to be captured on film quite precisely.

  • Filters (especially polarizer and graduated ND) are difficult to use.

  • The rangefinder is a mechanical device that needs to be calibrated every once in a while.

One drawback specific to this camera system is that DOF (depth of field) scales on Mamiya lenses appear way too optimistic and one normally has to be at least one stop conservative (many photographers suggest two stops, especially if you plan on making big enlargements).

Conclusions

To be completely honest, I have very mixed feelings about the camera. It does produce absolutely beautiful slides when used properly and in the way it was designed to be used in. However, I find it very difficult to live with some of the camera's limitations. I do not entirely enjoy using rangefinders to begin with and am discontented with the imprecise framing. Most importantly, though, the inability to precisely control exposure in manual mode is unacceptable to me.

If you enjoy using rangefinder cameras and the way the Mamiya 7II operates suits your shooting style, I am sure you are bound to be fond of the camera. Otherwise, I am afraid you will have to consider other options.
