---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ----------------------------------------------------------------------

The large aperture of F1.4 allows for photographic expression that makes use of an extremely shallow depth of field. The eight-blade circular aperture suppresses light beams when shooting point light sources and produces soft bokeh from maximum aperture to F2.8. The front of the lens is coated with SP (Super Protect) which is highly water- and oil-repellent and easy to wipe clean. By supporting aperture setting on the lens side and AF using an in-body motor, all functions can be used when the lens is attached to older K-mount digital SLR cameras or AF film SLR cameras.
