• No.5 - Working Distance (Approximate distance from the front of the lens to the subject): 5.5-7.9 inches / 14-20cm
• AC (Achromatic) corrected for chromatic aberrations - recommended for those who pursue a sharper photo.
• Made in Japan

Bonding the two lenses, to reduce the distortion of the surrounding, AC close-up lens to demonstrate the superior descriptive power. When AC No.5 is the focus position of the lens mount is ? (infinity), 0.20m from the shooting distance lens. Can be taken in a shorter distance if the focus position of the lens to the shortest. These close-up lens filters range from No.1 to No.10, where the larger the numerical value the closer to the subject focusing is allowed. Please choose more than No.3 If minimum shooting distance of you have of the lens of 11.8 inches (30cm) or less. AC (Achromatic) By combining a plurality of lenses, the lens is corrected for chromatic aberrations.Spherical aberration in comparison with the single lens type is also less, so you can get a clear image, and is recommended for those who pursue a sharper photo.
