【Tested and Working】Canon EF 28-105mm F3.5-4.5 USM Standard Zoom Lens This is a standard zoom lens for Canon full-frame cameras. It features an ultrasonic motor (USM) for very fast and quiet autofocus. It's compact and easy to carry, making it ideal as a go-to lens. ■ Condition ・Appearance There are minor scratches from use, but there are no major scratches or dents, and it maintains a good appearance for its age. ・Optics There is some mold on the rear element. It's difficult to see in normal light, but it's noticeable when a strong light is shone on it. I checked it by taking pictures, but I didn't feel any impact on the image quality (cloudiness or reduced contrast) in normal environments. You can use it without any problems at a practical level. ・Operation AF (Autofocus): Focuses very smoothly and accurately. MF (Manual Focus): The focus ring also operates smoothly. Zoom operation is also smooth without any sticking. ■ Compatible Models ・Single-lens reflex cameras (can be mounted directly) Full-frame: EOS 1D, 5D, 6D series models APS-C: EOS 7D, 90D, 80D, Kiss X10, Kiss X9i, Kiss X7, etc. (※With APS-C cameras, it can be used as a telephoto zoom equivalent to approximately 45-168mm) Film cameras: EF mount cameras such as EOS Kiss, EOS 55, EOS 7 ・Mirrorless cameras (requires a mount adapter) R series: EOS R, RP, R6, R7, R10, R50, R100, etc. M series: EOS M, M6, Kiss M, Kiss M2, etc. ■ Accessories ・Lens body ・Front cap (compatible) ・Rear cap (genuine) ■ Shipping and Other Due to the mold on the rear element, it is being offered at a lower price than the market average. It can be seen when a light is shone on it, but it did not affect the photos, so it's a great deal for those looking for "practical use." As it is precision equipment, it will be cleaned and disinfected, and carefully packed with cushioning material before shipping. If you have any questions, please feel free to comment.
