I recently purchased an Asahi SMC Macro-Takumar 50mm f/4 lens from Fuji X Weekly reader Tony Reidsma. I love Takumar lenses! Generally speaking, they are super sharp and have great character. There’s something special about them. They are often quite affordable, so you can add a bunch of Takumar lenses to your collection without going broke.

Asahi was the original name of Pentax. Up until the mid-1970’s when they switched from M42 screw-mount to K-Mount, Pentax used the Asahi brand name for their lenses. Asahi called their lenses Takumar in honor of the founder’s brother, Takuma Kajiwara, who was a famous photographer and painter. Asahi Takumar lenses require an M42 to Fuji X adapter, which can be found for cheap, to attach them to your Fujifilm camera.

The Asahi SMC Macro-Takumar 50mm f/4 is, no surprise, a macro lens. It has a 1:2 magnification ratio, which is not as close up as some macro lenses. An earlier version of the lens (without SMC) does, in fact, have a 1:1 magnification ratio. This SMC Macro-Takumar has a similar close-focus capability as the Fujinon 60mm f/2.4 Macro, which is good-but-not-great.

What I love about the Asahi SMC Macro-Takumar 50mm f/4 lens is that it’s very crisp. There’s some corner softness at f/4, but the lens is edge-to-edge super sharp at f/5.6 through f/11 (diffraction begins after f/11). I haven’t noticed much distortion, vignetting or chromatic aberrations. This lens has excellent contrast and controls flare very well. Bokeh is pretty nice, too. The lens is made of metal and feels very solid. It was a quality lens when it was new, and all of these decades later it is still a quality lens.

The Macro-Takumar is an all-manual lens. You’ll have to manually set the aperture and manually focus. The aperture ring on my lens is a little stiff, but otherwise works as it should. The focus ring is super smooth and accurate. Because it’s a macro lens, it takes a little effort to get from the close end to infinity, and the lens will actually focus just past infinity, which isn’t entirely unusual.

On the Fujifilm X-T30, because of the APS-C crop factor, the 50mm focal length is equivalent to 75mm. Essentially the Asahi SMC Macro-Takumar 50mm f/4 is a mid-telephoto prime that’s very sharp but with a maximum aperture of only f/4, which isn’t especially fast. It doubles as a macro lens, and it’s quite good at that, just as long as you’re not trying to get really close, as the magnification ratio isn’t particularly impressive. There are certainly shortcomings with this lens, but it has the “it factor” when it comes to image quality, producing especially lovely pictures. If you find this lens for a good price, be sure to buy it, because it’s worth having around. The technical specs of this Macro-Takumar lens won’t knock your socks off, but the images that it produces very well could.
