That being without the external finder to carry around. For the 50mm you can guestimate the composition and I just preferred the idea of a small camera setup. The Mamiya 43mm lens is wider so needs the additional external wide angle viewfinder. The Mamiya 50mm f/4.5 lens was the second Mamiya 7 lens I bought with the concept that if I bought the 50mm rather than the 43mm I could approximate the composition in the camera viewfinder. This prompted me to buy the Mamiya 7 210mm lens and soon after the Mamiya 150mm lens. I noticed I always wanted to be closer to my subject (or you could say the subject was always too far away for it to give any impact in the image)(and usually I couldn’t get close enough to change that fact). A year or so later I tried some Mamiya 7 35mm photos (loading 35mm film into the Mamiya 7 using a 35mm to 120 film adapter). I didn’t fall in love with the Mamiya 7 and I soon reverted back to my Hasselblad and Leica cameras. When I bought my Mamiya 7 camera I planned to use it for wide angle photos so I bought the 50mm lens and the 65mm lens. Here is a summary of the key data for each lens. In addition, lens hoods can offer some degree of physical protection for the lens due to the hood extending farther than the lens itself.There are six Mamiya 7 lenses available for the camera system – 43mm, 50mm, 65mm, 80mm, 150mm and 210mm. Lens hoods are often designed to fit onto the matching lens facing either forward, for normal use, or backwards, so that the hood may be stored with the lens without occupying much additional space. For wide angle lenses, the length of the hood cannot be as long as those for telephoto lenses, as a longer hood would enter the wider field of view of the lens. Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle lenses. This allows the lens hood to block stray light with the higher portions of the lens hood, while allowing more light into the corners of the image through the lowered portions of the hood. The geometry of the lens hood can vary from a plain cylindrical or conical section to a more complex shape, sometimes called a petal, tulip, or flower hood. This stray light often comes from very bright light sources, such as the sun, bright studio lights, or a bright white background. Flare occurs when stray light strikes the front element of a lens and then bounces around within the lens. Nevertheless, if it is absolutely necessary to use a hood, you can use one which is designed for 80mm f/1.9N lenses (67mm screw-in type).Ī lens hood or lens shade is a device used on the end of a lens to block the sun or other light source in order to prevent glare and lens flare. In this floating system, a portion of lens elements moves back and forth in accordance with the photographing distance to obtain the optimum lens performance.Īlthough this lens does not feature a hood, it provides a sufficient hood effect. The lens contains a built-in floating system which is designed to automatically compensate for increasing typical aberrations with close focusing distances to obtain sharp resolution down to the edges of the pictures. The Macro Space is coupled to the automatic diaphragm mechanism so that you can take pictures in exactly the same way as you would with a standard lens. By applying the optional Auto Macro Spacer which is especially designed for this Macro C 80mm f/4N lens, however, you can go up to life-size from 1/2 life-size magnification. You can focus up to 1/2 life-size with this lens without using an accessory. The Macro C 80mm f/4N lens is designed to provide a high resolving power not only in ordinary picture taking but particularly in close-up photograph and copying.
