[. . . ] ATTACHING TO CAMERA BODY AF AF G When this lens is attached to the camera body it will automatically function in the same way as your normal lens. On the lens mount surface, there are a number of couplers and electrical contacts. To avoid damaging the lens, be especially sure to place the lens with its front end down while changing the lens. [. . . ] This is due to possible focus shift resulting from extreme changes in temperature which cause various components in the lens to expand and contract. AF AF DEPTH OF FIELD SCALE The depth of field scale helps you to check the depth of field (the zone of sharpness) of your composition. For example in figure (3), the depth of field zone is shown when the aperture F16 is used. this lens hood helps to prevent flare and ghosted images caused by extraneous light. When using this dedicated hood adapter with digital cameras with an APS-C size image sensor, it provides more effective shading. Please attach the APS-C Hood Adapter between the lens body and the lens hood. 5) When using this lens with digital cameras with a full frame or APS-H size image sensor as well as film cameras, please do not attach the APS-C Hood Adapter. If you use the APS-C Hood Adapter with above cameras, vignetting will occur. In order to place the lens and hood into the storage case, you must first remove the hood, then replace it on the lens in the reverse position (fig. (It is possible to attach the lens hood in the reverse position and the front lens cap to the tip of the APS-C Hood Adapter, even if the APS-C Hood Adapter is attached to the tip of lens. Two or more filters and/or special thicker filters, like a polarizing filter, may cause vignetting. When using a polarizing filter with AF camera, use the “circular” type. When using filters with the APS-C Hood Adapter, please attach the filter to the filter attachment thread of the lens. If the filter is attached to the tip of the APS-C Hood Adapter, vignetting may occur. [. . . ] When entering a warm room from the cold outdoors, it is advisable to keep the lens in the case until the temperature of the lens approaches room temperature.
