How each alternative compares
Panasonic Lumix G 12-60mm F3.5-5.6
The Panasonic Lumix G 12-60mm F3.5-5.6 is a zoom lens for Micro Four Thirds cameras, unlike the Canon RF 45mm F1.2 STM which is a prime for Canon mounts. It offers focal length flexibility from 12mm to 60mm, whereas the Canon lens provides a fixed 45mm view. The Panasonic lens has a variable aperture of f/3.5-5.6, which is significantly slower than the Canon’s f/1.2 maximum aperture. This means less light gathering capability in dark environments. Weighing only 8 ounces, it is lighter than the Canon’s 1.21 pounds. Choose this if you need zoom versatility and compact travel size over low-light speed and portrait isolation.
Sigma 70mm F2.8 DG Art Macro Lens
The Sigma 70mm F2.8 DG Art Macro Lens is designed for Sony E-Mount cameras, not Canon RF. It features a 70mm focal length and f/2.8 aperture, differing from the Canon’s 45mm and f/1.2 specs. This lens is a dedicated macro tool, prioritizing resolution and close-focusing ability over the general-purpose portrait performance of the Canon. It weighs 1.1 pounds, slightly less than the Canon’s 1.21 pounds. The f/2.8 aperture is slower than f/1.2, reducing low-light performance. Select this if you shoot with Sony full-frame bodies and require macro capabilities rather than the wider aperture and specific focal length of the Canon RF 45mm.
Canon RF 35mm F1.8 Macro STM Lens
The Canon RF 35mm F1.8 Macro STM Lens shares the Canon RF mount but differs in focal length and aperture. It offers 35mm coverage and an f/1.8 maximum aperture, which is slower than the Canon RF 45mm F1.2’s f/1.2. This lens includes macro capabilities, allowing closer focus distances than the standard prime. It weighs 10.8 ounces, making it lighter than the Canon RF 45mm at 1.21 pounds. The smaller size and weight favor portability, while the wider aperture of the 45mm lens favors low-light shooting. Pick this if you need macro functionality and a lighter, more compact prime lens within the Canon ecosystem.
Nikon NIKKOR Z DX 50-250mm VR Lens
The Nikon NIKKOR Z DX 50-250mm VR Lens is a zoom lens for Nikon Z-mount APS-C cameras, distinct from the Canon RF 45mm F1.2 STM. It provides telephoto reach from 50mm to 250mm, unlike the fixed 45mm focal length. The lens includes vibration reduction for stabilization. It weighs 14.2 ounces, which is lighter than the Canon’s 1.21 pounds. The aperture is not specified as f/1.2, implying it is slower for low-light conditions. Choose this if you use Nikon APS-C bodies and need telephoto zoom versatility and stabilization rather than the wide aperture and prime lens characteristics of the Canon RF 45mm.
TTArtisan 50mm f/1.2 Manual Focus Prime Lens
The TTArtisan 50mm f/1.2 Manual Focus Prime Lens is for Micro Four Thirds cameras, not Canon RF. It offers a 50mm focal length and f/1.2 aperture, matching the Canon’s speed but differing in mount and focal length. This lens requires manual focus, unlike the Canon’s STM autofocus system. It weighs less than the Canon’s 1.21 pounds, with dimensions of 2.44 inches by 2.44 inches by 2.36 inches. The f/1.2 aperture provides similar low-light performance. Select this if you shoot with M4/3 bodies, prefer manual focus control, and want a compact prime lens with comparable aperture width to the Canon RF 45mm.
Viltrox 13mm f/1.4 Nikon Z Mount Lens
The Viltrox 13mm f/1.4 Nikon Z Mount Lens is a wide-angle prime for Nikon Z-mount APS-C cameras, unlike the Canon RF 45mm F1.2 STM. It offers a 13mm focal length and f/1.4 aperture, differing from the Canon’s 45mm and f/1.2 specs. This lens is designed for wide-angle photography, providing a much broader field of view than the standard lens. The f/1.4 aperture is slightly slower than f/1.2. It weighs less than the Canon’s 1.21 pounds. Choose this if you use Nikon APS-C bodies and need a wide-angle perspective with good low-light capability, rather than the portrait-oriented focal length of the Canon RF 45mm.
