Canon EF 100mm f/2.8L Macro IS USM Lens

Product Overview

The Canon EF 100mm f/2.8L Macro IS USM is a high-performance macro lens designed for Canon EOS cameras. It features an advanced Image Stabilizer (IS) and an Ultrasonic Motor (USM) for fast, quiet autofocusing. The lens is capable of 1:1 life-size magnification, making it ideal for detailed close-up photography as well as standard portrait work.

Key Features

The lens incorporates UD lens elements for superior image quality and a rounded aperture for smooth background blur. Its robust construction includes a dust-proof and drip-proof design. The integrated Image Stabilizer is highly effective, providing the equivalent of up to four stops of shutter speed compensation during normal shooting, and remains effective even during close-up photography.

Focusing and Operation

Users can switch between autofocus (AF) and manual focus (MF) using the focus mode switch. The lens also features a focusing distance range selection switch to optimize autofocus speed by limiting the search range. Full-time manual focus is available after autofocusing in One Shot AF mode. An infinity compensation mark is provided to adjust for focus shifts caused by temperature changes.

Image Stabilization

The Image Stabilizer is effective for hand-held shots, especially in low-light conditions, during close-up work, or when panning. It should be turned off when using a tripod or during long exposures (Bulb setting) to prevent potential errors. The stabilizer operates for approximately two seconds after the shutter button is released.

Macro Photography Techniques

Macro photography requires careful attention to depth of field, which is very shallow at high magnifications. To minimize camera shake during hand-held close-ups, it is recommended to hold the camera firmly, use a tripod, or utilize techniques such as leaning against a steady object. Setting the camera to AI Servo AF can also help maintain focus on moving subjects.

Maintenance and Safety

Always attach the lens cap when the lens is not in use. Avoid looking directly at the sun or bright light sources through the lens. When moving the lens between environments with significant temperature differences, place it in an airtight plastic bag to prevent condensation. Keep electrical contacts clean and free of fingerprints to ensure proper communication between the lens and camera.
