The Fujifilm X system has a comprehensive set of lenses available. There are two different denomination: XF and XC.
XF are the original X-Mount lenses. XC are Compact, and don’t have aperture rings.
Other suffixes are R, OIS, WR, LM, PZ, APD, Macro.
– R is for the “premium” line-up. XC lenses are not R.
– OIS denote in lens Optical Image Stabilisation.
– WR mean Weather Resistant, ie the lenses have seals to protect against the weather. Don’t be afraid to shoot in the rain with a weather resistant lens and body like the X-T3.
– LM means Linear Motor, silent motor for a fast autofocus. This is important for video recording.
– PZ means Power Zoom: the zoom is motorised and the user rotate the ring that controls the motor.
– APD mean Apodization meant to provide a better bokeh when wide open, suitable for portraits. There is only one lens with that suffix, the XF 56mm f/1.2 R APD.
– Macro is for lens that are designed for use in macro-photography, with reproduction ratio of 1:2 and higher.
– II is 2 on roman numeral and denote the second iteration of the lens with the same characteristics.
Some lenses have a “Red-badge” and are higher-end lenses.
There are two kind of lenses: prime and zoom.
Here are some samples.
Primes
Primes lenses have a fixed focal length. While sacrificing flexibility of not being able to change the focal length like a zoom, they are usually faster and more compact, optical perfection is more attainable. The original XF lineup was only 3 prime lenses, the XF 18mm F2 R, XF 35mm F1.4 R and the XF 60mm F2.4 Macro.
XF 14mm F2.8 R
This ultra-wide angle was the widest X-mount prime lens from Fujifilm until the release of the XF 8mm F3.5 R WR in 2023. The focus ring pulls to switch to manual focus.
It comes with a bayonette mounted lens hood the same as for the 18-55, and a clip-on lens cap. The filter thread diameter is 58mm.
XF 18mm F2 R
The 18mm was part of the original line-up for the X-Pro1. it was the wide angle. The compact form factor make the combination small. I got this quickly after I got the X-Pro1 to complement the 35mm.
It comes with a rectangular bayonette mounted lens hood, and a rubber lens cap.
XF 27mm F2.8 R WR
This 27mm is a pancake lens with a maximum apertures of f/2.8. Combined the smaller bodies it makes of a compact all around setup. When used with a weather resistant it make it ideal for shooting in the rain and other condition. It’s field of view equivalent to a 40mm in full frame provide what is often considered as the standard field of view.
It comes with a clip on lens cap, a screw on lens hood with a fit over lens cap.
XF 35mm F1.4 R
This lens, offering the field of view considered standard, was part of the initial line-up that came for the X-Pro1. That’s actually the lens I got with the X-Pro1.
The maximum aperture of f/1.4 offers a shallow depth of field and comes handy for low light conditions.
Comes with a rectangular bayonette mounted lens hood, and a rubber lens cap. The filter thread diameter is 52mm.
Zooms
XF 18-55mm F2.8-4 R LM OIS
A reasonable “standard range” zoom, the 18-55 came as a kit-lens with the X-T3. With built-in image stabilisation, and non-constant wide aperture it remains reasonably fast, better than the usual kit lenses from other brands, and is a less expensive alternative to the Fujifilm XF 16-55mm F2.8 R LM WR (II).
Comes with a bayonette mounted lens hood the same as for the 18-55, and a clip-on lens cap. The filter thread diameter is 58mm.
Other
There are also cinema lenses, with the Fujinon MKX denomination. These are the X-Mount versions of the Fujinon MK for E-mount (Sony) dedicated to the Super-35 format. These lenses are entirely manual focus and zoom, with gears to allow coupling for focus pulling. And they are quite big.
There are two extension tubes available, one 11mm and one 16mm. They allow increasing the magnification ratio on most lenses.
