Fuji achieves this with an “inner focus af system” that uses a stepping motor to move the relatively small focusing elements in the middle or rear of the lens. Take Kayo aka BIGHEADTACO is a Vancouver photographer, camera reviewer, YouTuber, instructor and iPhoneography advocator.

The f/2 aperture is fairly modest for this type of lens, being a third of an f/stop slower than that of more typical f/1. If you want to see a great review with the gorgeous product photos, then check out Jonas Rasks' page.

You could conceivably even slip this lens into a jacket pocket ready for quick switching with a different Fujifilm lens in the f/2 range. With the lens hood attached you can see the lens in the bottom corner of the OVF but it just barely touches the corner of the 23mm frameline. You might think these two Fujifilm prime lenses cost a small fortune seeing as they both have so many great qualities, but you would be wrong. The XF23mmF2 R WR is great for low-light use, helping X Series users to keep shooting handheld, but it is also useful when you want to blur the background for professional-looking portraits.

The thread size of the Fujifilm XF 23mm f/2 R WR lens is 43mm, which is the same as the 35mm f/2, but different from the 46mm thread of the 50mm lens. When shooting at the widest aperture of f/2, it’s possible to see some slight drop-off in light at the corners of the image. Let’s just start off by saying that both of these Fujifilm prime lenses are outstanding at what they do.I decided to test the XF 23mm f/2 R WR exactly how I would normally use it, as a portable compact solution for travel. Although fairly small and lightweight, at just 60x52mm and 180g, build quality is excellent, with a metal barrel and a full set of weather-seals.
