Hasselblad's configuration

For professional photography, macro lens is the most ideal equipment for close-up photography. Because the macro lens is specially designed for close-range photography, this lens performs maximum optical aberration correction on magnification, which is superior to the ordinary lens in distortion and aberration control, and is easy to cooperate with the fuselage to realize various automatic exposure functions. When it comes to Hasselblad macro lens, many people immediately think of the famous Zeiss Makro-Planar CF F4/ 120mm macro lens. In fact, Hasselblad's first macro lens is Zeiss S-Planar CF F5.6/ 120mm, which has black and white colors like many Hasselblad C mirrors. The biggest difference from the CF mirror produced in the later period is that the ratio of image to object is 65438.

Since CF, Zeiss has successively produced three f4/ 120mm macro lenses for Hasselblad: CF, CFi and CFE. Because the object ratio of this lens is only 1:4.5, it can only be regarded as a close-up focus lens according to the recognized close-up standard 1: 10 to 1. This lens is named Makro because it is suitable for close-up shooting, and it is also excellent for portraits and landscapes. The large aperture design can avoid the loss of light caused by lens elongation, and the image can be moderately corrected, and the quality from the center to the corner can reach the highest, especially when shooting plane images, which can provide high contrast and clarity. The lens consists of 4 groups of 6 lenses, and the shutters between the lenses are symmetrically arranged on both sides, which can best reflect the Excellence of this head when shooting at close range. The shooting distance is 0.8m, and the magnification is 1:4.5, which can be increased to 1:2 after connecting Hasselblad extension ring 32E. It is an excellent macro camera lens. Among the three macro lenses, CFi and CFE are completely consistent with CF in structure, volume and weight. CFi has improved the shutter and lens materials on the basis of CF, the inside of the lens barrel has been treated by flocking and extinction, and the lens mouth is made of engineering plastic to prevent wear and exposure. The lens focus ring needs to rotate 3/4 times from 0.8m to infinity, of which 0.8m to 3m rotates 1/2 times. CFE adds electronic contacts to CFi. CF and CFi lenses have been discontinued, and only CFE lenses are still produced and sold.

Hasselblad f4/ 120mm lens is specially designed for macro photography, which is convenient and quick. Excellent image quality and uniform exposure can still be guaranteed under full aperture, and it can also be used for other purposes. The main disadvantage is that the maximum object-to-object ratio is only 1:4.5, and ordinary single flowers can't make up the picture. Compared with the macro lens of 135 camera, its application range is not enough, the maximum relative aperture is small, and its volume and weight are large.

The brand-new Hasselblad close-up skin cavity and the matching CF f5.6/ 135mm close-up lens linkage telescopic cavity are special accessories for connecting the fuselage and the lens. One end is connected to the lens bayonet of the fuselage, and the other end is connected to the photographic lens. Its function is to extend the image distance between the fuselage and the lens, so as to obtain a higher macro magnification that can be adjusted continuously. The calculation method of exposure compensation for lens-linked telescopic cavity can refer to the related contents of the close-range ring part behind.

The telescopic leather cavity produced by Hasselblad was earlier. The early leather cavity was made of steel and aluminum alloy, and the pleated cavity was soft leather. The telescopic range is 53.5-202 mm, and it is equipped with a double shutter switch wire, which can release the shutter and lens of the fuselage at the same time. There is a lens shutter wrench at the junction of the leather cavity and the lens, which is not convenient to use. During this period, Zeiss S-Planar f5.6/ 135mm was a special lens for close-up of telescopic leather cavity. Like the lens produced in the later stage, this lens can only be used on the telescopic leather cavity, and the focusing range is from 53.5 mm to infinity. The filter adopts Hasselblad 50mm bayonet.

The new lens linkage telescopic cavity adopts monorail structure, which has made many improvements compared with the old one. Especially through the transmission mechanism on the guide rail, the leather cavity can be linked with the lens, and the fuselage and the lens can be wound at the same time, thus eliminating the need for double-headed pay-off. All operations are exactly the same as the lens is directly installed on the fuselage. The lower part of the guide rail is provided with a quick connection seat plate, which is convenient for the quick connection seat to be connected with the tripod and can move back and forth on the guide rail, thus facilitating the accurate adjustment of the whole machine body.

The new Zeiss Makro-Planar CF F5.6/135 mm macro lens, like the previous generation, can't be directly installed on any Hasselblad fuselage, and it doesn't have a focusing ring, so it needs to be used in conjunction with the linkage telescopic cavity. When the longest extension distance of the skin cavity is 202 mm, the ratio of the original size of the skin cavity is 1: 1, and when the shortest extension distance is 63.5 mm, the skin cavity can take an infinitely long image. Suitable for all kinds of close-up, documentary, natural and scientific photography. When 503CW+ telescopic leather cavity +CF f5.6/ 135mm shortest leather cavity is 63.5 mm, the frame size is close to CFE F2.8/80mm+32e; When shooting at 120 mm, the image-to-object ratio approaches 1:2, and the viewfinder picture begins to darken, and the top is blocked. The use principle and method of the close-range distance extension ring are basically the same as those of the close-range leather cavity. Its principle is to connect between the lens and the fuselage to extend the distance between them. Due to the increase of image distance, a higher magnification can be obtained in the end. The main difference is that the magnification of close-up skin cavity can be adjusted continuously, and the magnification of close-up joint ring is fixed or adjusted in steps. Its magnification varies according to the focal length of the lens used and the extension length of the connecting ring. The shorter the focal length of the lens, the longer the extension length of the connecting ring, and the higher the magnification after combination. Hasselblad manufacturers do not recommend the use of extension rings for lenses below 60 mm

Hasselblad produced two generations of close-up connecting rings, including 40363 extension pipe 10, 4054 1 extension pipe 16, 400 10 extension pipe 2 1, 40568 extension pipe 32 and 40029 extension pipe 55. These connecting rings are made of aluminum alloy, and their surfaces are anodized to black. Using 50mm Hasselblad standard plug-in interface, the transmission device can cooperate with the fuselage to complete the winding and release of the lens shutter. The focus range and object image of the old close-range ring connected with 80mm meter head are as follows: the focus range of 80mm lens+close-range extension ring 10 is 8 1.2-52cm, and the object-image ratio is1:8; 80mm lens+close range extension ring 2 1 focus range is 40-48.5cm, and the image-object ratio is 1: 3.8. The focus range of the 80mm lens and the close-range extension ring 55 is 3 1.9-32.8 cm, and the image-object ratio is 1: 1.45.

In the late Soviet Union, four kinds of close-range extension rings were produced, namely, close-range extension ring 8, close-range extension ring 16E, close-range extension ring 32E and close-range extension ring 56E, and the new Hasselblad φ φφ60mm standard plug-in interface was adopted. Due to the volume problem, the close-range ring 8 cannot be directly installed on the 200 or 2000 series fuselage, and the display of digital data will be interrupted if it is installed between the FE/CFE lens or the E-type rangefinder. Other 16E, 32E and 56E are equipped with digital data contacts, which can be used on all Hasselblad fuselage. The built-in digital data contact can transmit lens data to the 202FA, 203FE and 205FCC fuselage for use. The new close-up ring connects the side length of the 80mm head shooting object, and the object is as follows:

80mm lens+16E Close-up shot an object with a side length of 170 mm and an image-object ratio of 1:5.

80mm lens +32E close-up shot of an object with a side length of 102 mm, with an object ratio of 1:2.5.

80mm lens +56E close-up shot of an object with a side length of 62 mm, the object ratio is 1: 1.42.

The 80mm lens+16E+32E has a close-range object length of 74 mm and an object ratio of 1: 1.66.

80mm lens+16E+56E Close-up shot an object with a side length of 5 1 mm, and the image-object ratio is1:1.1.

80mm lens +32E+56E close-up lens shoots an object with a side length of 43mm, and the object-to-image ratio is 0.9 1: 1.

80mm lens+16E+32E+56E Close-range shooting object side length is 37 mm, and the image-object ratio is 0.77: 1.
