Meike 50mm F1.8 AF Key Differences
Minimum Focus Distance
The Meike 50mm F1.8 AF STM Full Frame Portrait Lens for Nikon Z Mount Cameras offers a minimum focusing distance of 0.63 meters. This specification allows you to get closer to your subjects, which is useful for strong close-up performance in portrait and street photography. The competing Meike 50mm F1.8 Full Frame AF Lens for Nikon Z Mount Mirrorless Cameras does not list a minimum focusing distance in its provided data. Without this specific measurement, you cannot compare how close either lens can get to a subject. For buyers who prioritize macro-like capabilities or tight framing, the listed 0.63m distance provides a concrete advantage for the first lens.
Physical Dimensions
You can see a significant difference in the physical footprint of these two lenses. The Meike 50mm F1.8 AF STM Full Frame Portrait Lens measures 2.83 inches in width and height, with a length of 4.06 inches. In contrast, the Meike 50mm F1.8 Full Frame AF Lens lists dimensions of 0.39 inches for width, height, and length. These measurements for the second lens appear inconsistent for a full-frame prime lens, as they suggest an extremely small form factor. If the data is accurate, the second lens is substantially more compact. However, the first lens provides clear, standard dimensions that you can rely on for bag planning and balance with your camera body.
Weight Specification
Weight is a practical factor for handheld shooting, especially with larger mirrorless bodies. The Meike 50mm F1.8 Full Frame AF Lens for Nikon Z Mount Mirrorless Cameras explicitly states a weight of 10.6 ounces. This data point helps you gauge the balance and fatigue during long shooting sessions. The Meike 50mm F1.8 AF STM Full Frame Portrait Lens for Nikon Z Mount Cameras does not provide a weight specification in its data. Because you lack the weight data for the first lens, you cannot determine which is lighter. The second lens has the advantage only because it provides a concrete number for comparison, while the first remains undefined.
Firmware Update Method
Maintenance and updates can affect long-term usability. The Meike 50mm F1.8 Full Frame AF Lens for Nikon Z Mount Mirrorless Cameras features a Type-C interface for firmware upgrades. This allows you to update the lens software directly via a cable, with updates available from the official website for Android devices. The Meike 50mm F1.8 AF STM Full Frame Portrait Lens for Nikon Z Mount Cameras does not mention firmware update capabilities or ports in its data. If you value the ability to fix autofocus issues or improve performance through updates, the second lens offers a clear method for doing so. The first lens leaves this aspect unspecified.
Aperture Blade Count
The number of aperture blades influences the shape of the bokeh in out-of-focus areas. The Meike 50mm F1.8 AF STM Full Frame Portrait Lens for Nikon Z Mount Cameras specifies 9 aperture blades. This count typically results in a more circular bokeh shape, which many portrait photographers prefer for smoother background blur. The Meike 50mm F1.8 Full Frame AF Lens for Nikon Z Mount Mirrorless Cameras does not list the number of aperture blades in its specifications. While both lenses share an f/1.8 maximum aperture, the first lens provides specific data on its optical construction that affects image quality. This makes it the stronger choice if you care about bokeh characteristics.
Which Meike 50mm F1.8 Should You Buy
Travelers wanting minimal bulk
This model weighs 10.6 ounces and measures 0.39 inches in width and height. The compact dimensions make it easier to carry during long shoots. You benefit from a lightweight design without sacrificing the f/1.8 aperture or STM autofocus performance for portraits.
Shooters needing close focus
This lens offers a minimum focusing distance of 0.63 meters. This specification allows you to get closer to your subjects for tighter portraits or details. The 9 aperture blades also create smoother bokeh, enhancing background blur for isolated subjects in low light.
Users wanting firmware updates
You can upgrade the firmware online via a Type-C interface. This feature supports real-time updates for Android devices, helping to maintain autofocus performance. It is a practical option if you prefer keeping your gear software current without visiting a service center.
