I'm listing another item as it came out of indoor storage. It has been used once for testing. The inner plastic bag is not included. Release Date: March 2005 Original Price: ¥57,000 Lens Configuration (Groups): 8 Lens Configuration (Elements): 12 Aperture Blades: 7 Minimum Aperture: 32 Minimum Focusing Distance (m): 0.2 Maximum Magnification: 1x Filter Diameter (mm): 52 Maximum Diameter x Length (mm) x (mm): 73 x 69.8 Weight (g): 335 EF-S lenses, which feature optical systems and mechanical structures optimized for digital SLR cameras with image sensors smaller than 35mm full-frame (APS-C size), have been gradually expanded since 2003. They can be used with the EOS DIGITAL series, including the "EOS Kiss Digital N" released at the same time, and the "EOS 20D," which has received high praise from advanced amateurs since its release in September 2004. This is a medium telephoto macro lens capable of 1x magnification. The optical design leverages the advantages of a short back focus, which shortens the distance from the lens's final surface to the image plane, and a small image circle, achieving both lightweight and compact design, as well as 1x macro photography with a focal length equivalent to 96mm in 35mm format. Furthermore, similar to the EF lens "EF100mm F2.8 Macro USM" (released in March 2000) compatible with 35mm full-frame, it employs an inner focusing system with a 3-group floating system, achieving high image quality across the entire shooting range and securing a working distance of 90mm, the longest in its class* during 1x magnification. In addition, the optical design is carefully considered to prevent adverse effects on image quality when light passing through the lens is reflected by the image sensor of a digital SLR camera, and the optimization of the coating achieves both suppression of flare and ghosting and a good color balance.
