Supermicro APO lens for Canon EF

The Venus Optics Laowa Aurogon FF 10-50x NA0.5 Supermicro APO Lens mounts on Canon EF cameras and delivers magnification from 10x to 50x. It targets scientific imaging and artistic macro work where resolving microscopic detail is the primary goal. Four interchangeable magnification tubes provide discrete steps at 10x, 20x, 35x and 50x without recalibration. The apochromatic design controls chromatic aberration across the 435-656nm wavelength range for accurate colour rendition.

Adjustable numerical aperture

The lens offers an adjustable numerical aperture from 0.5 down to 0.15, letting the photographer balance depth of field, brightness and diffraction for each magnification. A constant 20mm working distance is maintained across all tubes, giving consistent clearance for lighting rigs and sample manipulation. Focal lengths shift from 18.8mm at the lowest power to 5.56mm at the highest, optimising optical performance at every step.

Interchangeable magnification tubes expand

The four supplied tubes replace the need for multiple dedicated optics, allowing immediate changes between 10x, 20x, 35x and 50x magnification. Each tube is calibrated so focus and aperture settings remain valid, reducing setup time in laboratory or field conditions. No additional software or electronic accessories are included; the system is purely optical and mechanical.

Questions about this item

How do I install the magnification tubes on the Canon EF mount, and which step do users often miss?

Attach the lens to the Canon EF mount first, then thread the chosen magnification tube (10X, 20X, 35X, or 50X) onto the lens barrel; the step often missed is confirming the tube clicks into its detent so the 20 mm working distance stays fixed.

What maintenance or replacement will the adjustable numerical aperture mechanism need over time?

The iris blades that shift the numerical aperture from 0.5 down to 0.15 should be kept free of dust; if blade movement becomes stiff, a professional clean-and-lubricate service restores smooth aperture control.

At which magnification does the fixed 20 mm working distance become the limiting factor for lighting under sustained use?

At 50X the 20 mm working distance leaves the least room for illumination, so lighting placement becomes the first practical limit during extended sessions.
