Customized Production of Full-Frame Large-Aperture Prime Lenses

As a highly flexible optical lens manufacturer, Leedsen offers customized services for various focal lengths, including 35mm, 85mm, and 100mm, based on the same high-standard optical platform. This lens series supports a maximum fast aperture of F1.4, perfectly covering Full-Frame sensors. For brands seeking prime lens OEM services, this means leveraging our proven solutions to quickly build a high-end product line covering wide-angle portraits to telephoto close-ups, significantly shortening development cycles.

Flexible Focusing Systems and Mechanical Structures

Our engineering team provides unique “modular” manufacturing solutions. Depending on your target market needs, we can configure the product as a classic manual focus cine lens, equipped with a mechanical focus ring with comfortable damping and a depth-of-field scale (as shown in the image); or upgrade it to an autofocus prime lens assembly supporting modern electronic contacts. This technological flexibility makes us an ideal custom camera lens supplier, providing precisely matched hardware support whether you’re serving nostalgic film photographers or modern digital mirrorless users.

Precision Metal Body and Durability

In B2B sourcing, product quality directly determines premium pricing. Leedsen insists on using high-precision all-metal lens housings, rather than cheap engineering plastics. This robust construction not only enhances stability during handheld shooting but also effectively protects the delicate internal optical components. As a quality-focused private label lens factory, we support laser engraving or custom nameplate designs on the metal lens bodies, helping photography equipment brands create highly recognizable and luxurious high-end optical products.

Cross-Platform Mount Compatibility

To adapt to the complex market environment, our lens lineup is fully compatible with mainstream SLR and mirrorless systems. The specifications show support for multiple interfaces, including Canon EF/RF mounts, Nikon FX, and Sony E-mount. This broad compatibility eliminates inventory concerns for mirrorless lens distributors. You no longer need to search through multiple suppliers; by connecting with Leedsen, a comprehensive optical solution provider, you can procure F1.4 high-speed prime lenses compatible with different camera ecosystems in a one-stop shop, efficiently responding to the diverse needs of the end market.
