Aksen 2-lens Bundle [45mm f/2.8, 17.5mm f/1.7 (Coaxial Illumination Version)] Nikon F

The 45mm lens covers 1–5X magnification with a fixed 40.35 mm working distance, while the 17.5mm lens continues from 5–10X with a fixed 22.48 mm working distance. Each lens is parfocal within its own zoom range, so focus remains locked as magnification changes and the barrel stays fixed.

Both lenses use apochromatic optical designs to reduce chromatic aberration and colour fringing at high magnification. The 17.5mm lens is the Coaxial Illumination Version and can be paired with the optional Laowa USB coaxial light for more even, low-shadow illumination on very small subjects.
