In this video I review the AstrHori 25mm f/2.8 2–5x Ultra Macro lens, and yeah—this thing is basically a microscope for my full-frame camera. I’m used to topping out at 2x on this channel, so jumping to 5x is wild. I do a quick unboxing (AstrHori’s packaging is honestly one of the best), then I break down the build: all-metal lens body, metal pressure-fit front cap, metal mount, tiny front element, no filter threads, and a clicky aperture ring from f/2.8 to f/16. It’s a fully manual lens, and it looks super unique once you mount it on something like my Canon R6 Mark II—especially when you rack it out from 2x to 5x. Then I get into real-world shooting: how insanely close you have to be to your subject, how shaky handheld macro can get, and why a tripod is basically the move. This lens is hungry for light—I was pushing high ISO indoors, and for my cleaner samples I used a tripod, a timer, and two 100W lights to keep shutter speed usable. The payoff is legit: razor-sharp images even around f/4, no obvious vignetting on full-frame, and minimal chromatic aberration once stopped down. If you need dedicated macro for textures, jewelry, and extreme detail, I genuinely think this is a killer budget option compared to the big brands.
