Overview of the Lenses

The 85mm f1.8 Portrait Lens - F Lens for Nikon is priced at $96.22, making it significantly more affordable than the Canon RF45mm F1.2 STM, which costs $469.00. This price difference of about 79% means that budget-conscious photographers might lean towards the Nikon-compatible lens, especially if they are looking for a manual focus option.

The 85mm lens is designed specifically for Nikon DSLR cameras, enabling users to capture stunning portraits and detailed close-ups. In contrast, the Canon RF lens is a versatile 45mm prime lens suitable for a variety of shooting scenarios, including portraits and lifestyle photography.

Compatibility

The 85mm f1.8 Portrait Lens is compatible with a wide range of Nikon DSLR models, including the D3500, D850, and D7500, among others. This extensive compatibility ensures that many Nikon users can take advantage of its features. However, it is important to note that this lens requires manual focus, which may not appeal to everyone.

On the other hand, the Canon RF45mm F1.2 STM is designed specifically for Canon's RF mount cameras. This lens utilizes a large-diameter mount and is optimized for digital distortion correction, which enhances image quality when paired with Canon's mirrorless systems. Users must ensure that they own compatible Canon cameras to fully benefit from this lens.

Focus Mechanism

The 85mm f1.8 Portrait Lens operates solely on manual focus, requiring users to rotate the focus ring to achieve sharp images. This approach can be both challenging and rewarding, as it encourages a more hands-on shooting experience. However, it may not suit everyone, particularly those accustomed to the convenience of autofocus.

Conversely, the Canon RF45mm F1.2 STM benefits from a more modern autofocus system, allowing users to capture images quickly and efficiently. The autofocus system is particularly advantageous for photographers who need to react swiftly to changing scenes or subjects. This difference in focus mechanism is a crucial factor for potential buyers to consider based on their shooting style.

Aperture and Image Quality

The 85mm f1.8 lens features a wide f/1.8 aperture, which is ideal for creating beautiful background bokeh and achieving a shallow depth of field. This makes it perfect for portrait photography, where isolating the subject from the background is essential. The lens also allows for effective low-light performance, although manual adjustments are required for exposure.

In contrast, the Canon RF45mm F1.2 STM boasts an impressive f/1.2 aperture, enabling even faster shutter speeds in darker environments. The larger aperture contributes to exceptional bokeh and three-dimensional imagery, effectively isolating subjects from their backgrounds. This lens is particularly appealing for those who prioritize low-light performance and artistic depth in their photography.

Size and Portability

The 85mm f1.8 Portrait Lens is compact and lightweight, making it a practical choice for photographers who prioritize portability. This feature allows for easy handling and transport, especially during long shooting sessions or when traveling.

The Canon RF45mm F1.2 STM, while still relatively compact for a lens with a f/1.2 aperture, is somewhat bulkier due to its advanced design and features. However, its compact nature compared to other f/1.2 lenses makes it an attractive option for those seeking a balance between performance and portability. Ultimately, the choice between these lenses may depend on how much weight and size matter to the prospective user.

Price and Value

The 85mm f1.8 Portrait Lens is priced at $96.22, offering a budget-friendly option for photographers who want quality without breaking the bank. Given that it is about 79% cheaper than the Canon RF45mm F1.2 STM, it provides excellent value for those who can work with manual focus.

The Canon RF45mm F1.2 STM, priced at $469.00, represents a significant investment. However, its advanced features, including superior autofocus and a larger aperture, may justify the cost for professional photographers or enthusiasts looking to elevate their work. In this regard, each lens offers distinct value propositions that cater to different user needs.

Intended Use Cases

The 85mm f1.8 lens is perfect for portrait photography, street photography, and situations where a natural perspective is desired. Its design allows for stunning close-ups and half-body shots, making it an excellent choice for photographers focused on human subjects.

The Canon RF45mm F1.2 STM excels in various applications, from portraits to lifestyle photography. Its versatile focal length and exceptional low-light capabilities make it suitable for capturing a wide range of scenes, whether in controlled environments or dynamic outdoor settings. Depending on your typical shooting scenarios, one lens may prove more advantageous than the other.

Which should you buy?

Ultimately, the decision between the 85mm f1.8 Portrait Lens - F Lens for Nikon and the Canon RF45mm F1.2 STM depends on your specific needs and preferences. If you are a Nikon user seeking a budget-friendly manual focus lens that excels in portrait photography, the 85mm f1.8 is a strong contender at $96.22.
