Price Comparison

The Canon EF-S 10-18mm f/4.5-5.6 is STM Lens is priced at $349.00, making it significantly more budget-friendly than the Canon RF100mm F2.8 L Macro is USM Lens, which costs $1,248.95. This means the RF100mm is about 258% more expensive than the EF-S 10-18mm lens. If you are a photographer or videographer looking to save money while still obtaining quality optics, the EF-S 10-18mm lens is a more accessible option. However, the higher price of the RF100mm lens could be justified by its advanced features and capabilities, particularly for macro photography.

Intended Use

The Canon EF-S 10-18mm f/4.5-5.6 is designed for wide-angle photography, making it an excellent choice for landscape, architecture, and travel photography. Its ultra-wide zoom capability allows for expansive shots, while the stepping motor ensures quiet operation, particularly beneficial for video recording. In contrast, the Canon RF100mm F2.8 L Macro is tailored for medium telephoto and macro photography, making it ideal for portraits and close-up shots. With a maximum magnification of 1.4x, it excels in capturing fine details in subjects like flowers or small objects, offering versatility in creative photography.

Image Stabilization

Both lenses incorporate optical image stabilization, but their effectiveness varies. The Canon EF-S 10-18mm lens provides up to four equivalent stops of shake correction, which is beneficial in low-light conditions or when shooting handheld. Meanwhile, the RF100mm lens boasts a more advanced stabilization system, offering up to five stops of shake correction. This added feature is particularly advantageous for macro shooting, where even the slightest movement can affect image clarity. Those prioritizing stability in their shots may find the RF100mm lens more suitable for their needs.

Focal Length and Aperture

The EF-S 10-18mm lens features a focal length of 10-18mm with a variable aperture of f/4.5 to f/5.6, making it versatile for wide-angle shots but limiting in low-light conditions. Its wide-angle capability is perfect for capturing expansive landscapes. On the other hand, the RF100mm lens has a fixed focal length of 100mm with a bright f/2.8 aperture, which allows for excellent low-light performance and the ability to create a beautifully blurred background. For photographers focused on portraiture or macro work, the RF100mm offers a distinct advantage in terms of depth of field and light-gathering capability.

Autofocus Performance

Autofocus performance is critical in photography, especially for capturing fast-moving subjects. The Canon EF-S 10-18mm lens features a refined focus mechanism powered by a stepping motor, enabling smooth and continuous autofocus during video recording. This is ideal for videographers needing quiet and unobtrusive focusing. In contrast, the RF100mm lens offers fast, highly-precise autofocus, which is essential for capturing fleeting moments in macro or portrait photography. Photographers looking for speed and accuracy in their shots may prefer the advanced autofocus features of the RF100mm.

Design and Build Quality

When it comes to design and build quality, the RF100mm lens is part of Canon's premium L series, which typically signifies superior construction and durability. It includes a spherical aberration (SA) control ring that allows users to manipulate the bokeh effect, adding creative flexibility to portrait shots. The EF-S 10-18mm lens, while well-constructed for its category, lacks the same level of premium features. For those who prioritize high-end materials and advanced control options in their lenses, the RF100mm may be the better choice.

Compatibility

The EF-S 10-18mm lens is specifically designed for Canon EOS cameras with an APS-C sensor, making it an excellent option for users of that system. Conversely, the RF100mm lens is designed for full-frame EOS R series mirrorless cameras, showcasing its advanced capabilities tailored for modern photographers. If you own an EOS R series camera, the RF100mm is the clear choice, while the EF-S 10-18mm lens is more suited for those with APS-C systems looking for a versatile wide-angle lens.

Which should you buy?

Choosing between the Canon EF-S 10-18mm f/4.5-5.6 is STM Lens and the Canon RF100mm F2.8 L Macro is USM Lens ultimately comes down to your specific photography needs and budget. The EF-S 10-18mm lens is significantly more affordable at $349.00 and excels in wide-angle photography, making it a great choice for everyday use.
