Operation of the Hasselblad Arcbody camera.

When first exposing your image you will notice that the edges of the image get darker. We call this light fall off or vignetting. The purpose of the Hasselblad Center Density (CD) Filter 47057 is to compensate for this fall off. The glass is coated with neutral density coatings that gradually get darker towards the center of the filter.

The CD Filter should be used at all times with the 35mm and 45mm lenses.
The filter can be removed to brighten focus, don't forget to put it back.
The filter is recommended for use with the 75mm lens when extreme shift is employed and should be left in place during focus.
The filter is attached to the holder 47018 which bayonets into the front of the lenses.
Any additional M77 screw filters attached onto the CD filter will cause vignetting.

At extreme shift with the 35 and 45 lenses you may close down your aperture to f/16 or smaller to correct light fall off.

After taking a light meter reading reduce the EV value by 2 stops, for example EV 5 becomes EV 3. In other words you could slow down your shutter speed 2 stops (i.e. 1/125 to 1/30) or open the aperture 2 stops (f/8 becomes f/4).

The 75mm lens has an extension tube of 26mm attached. Although removable it is intended to be left on at all times.

All Hasselblad viewfinders can be used on the Arcbody's focusing screen adapter. If using a pop up waist level finder a diopter of -1 is recommended. The RMfx (72530) viewfinder is a right angle reflex most recommended for comfort and corrected viewing. It can be used inverted with the Inverter mount. Before taking a light measurement with a prism be sure to set shift and tilt to zero, remove the center filter. Insert the small correction slide when using the 35mm or 45mm lenses. Insert the stray light mask when using the 75mm lens. When taking a reading with the 35mm lens remember to open up 0.5 f/stop.

Shift, tilt and close up settings are chosen according to the desired effect as seen through the lens. The 8mm Extension Tube is used with the 35mm and 45mm lenses to produce reproduction ratios of 0.25 or 1/4 lifesize. The 16mm tube produces a similar 0.25 magnification ratio with the 75mm lens. When combining tubes place the 8mm tube closest to the lens to reduce vignetting during shift. The less shift used the greater the tilt available. When the 26mm tube is used in conjunction with the 35mm or 45mm lens the use of the 10° or 20° Correction slide will improve brightness. The bellows of the Arcbody is made by Lee and is very durable. Storage should be in neutral shift / tilt however.
