Overview of the Canon RF45mm F1.2 STM and Sony SEL90M28G

The Canon RF45mm F1.2 STM is priced at $469.00, making it significantly cheaper than the Sony SEL90M28G, which retails for $1,048.00. This price difference of about 55% may influence the purchasing decision for many photographers. Both lenses cater to different photography styles, with the Canon lens leaning towards portrait and lifestyle photography, while the Sony lens is designed for macro and detailed shots.

Design and Build Quality

The Canon RF45mm F1.2 STM features a compact design that is easy to handle, making it suitable for casual shooting and portability. With a large-diameter mount and a short back focus, Canon has crafted a lens that balances size and performance. On the other hand, the Sony SEL90M28G prioritizes durability, boasting a dust and moisture-resistant design. This feature is especially beneficial for outdoor photographers who may encounter varying weather conditions. The weight of the Sony lens is 602 g (21.3 oz), which might impact how comfortable it feels during extended use, especially compared to the Canon lens.

Optical Performance

The Canon RF45mm F1.2 STM excels in low-light situations thanks to its wide f/1.2 aperture, allowing for faster shutter speeds. This feature is particularly valuable for capturing dynamic portraits and lifestyle shots with a soft, expressive bokeh. Conversely, the Sony SEL90M28G offers a maximum aperture of f/2.8, which, while not as wide, still provides good performance in various lighting conditions. The Sony lens also features advanced optics, including Super ED glass and a floating focus mechanism, which helps maintain sharpness across all focusing distances.

Bokeh and Background Isolation

Both lenses are designed to create beautiful bokeh, but they achieve it differently. The Canon RF45mm F1.2 STM's large-diameter lens allows for a three-dimensional look that effectively isolates subjects from their background, making it an excellent choice for portrait photographers. The Sony SEL90M28G, with its 9-blade circular aperture, also produces a pleasing bokeh, although its primary strength lies in macro photography, where the background can be blurred to emphasize intricate details of the subject.

Focusing Mechanism

The Canon RF45mm F1.2 STM benefits from a straightforward focusing mechanism that is geared towards ease of use, making it ideal for photographers who prefer a more traditional approach. In contrast, the Sony SEL90M28G features a Direct Drive SSM (DDSSM) for quiet and precise focusing, which is essential for capturing fine details in macro photography. This difference in focusing technology can be a deciding factor for users depending on their shooting style.

Price Comparison

The Canon RF45mm F1.2 STM is currently available for $469.00, while the Sony SEL90M28G costs $1,048.00. This makes the Canon lens approximately 55% cheaper than its Sony counterpart. For budget-conscious photographers or those just starting, the Canon provides a compelling choice without sacrificing quality. However, the Sony's advanced features and build quality may justify the higher price for professionals focused on macro photography.

Target Audience

The Canon RF45mm F1.2 STM is tailored for creators looking to enhance their portrait and lifestyle photography. Its compact design and impressive low-light performance cater to a wide range of shooting scenarios, from casual to more serious photography. In contrast, the Sony SEL90M28G is aimed at professionals and enthusiasts who require a specialized macro lens capable of capturing intricate details and textures in subjects. This distinction in target audience highlights the different uses for each lens and how they fit into a photographer's toolkit.

Which should you buy?

Ultimately, the decision between the Canon RF45mm F1.2 STM and the Sony SEL90M28G comes down to your specific photography needs. If you're looking for a versatile, budget-friendly lens that excels in portraiture and low-light conditions, the Canon lens is an excellent choice. However, if your focus is on macro photography and you require advanced features such as image stabilization and superior optical performance, the Sony lens may be worth the investment despite its higher price.
