What's the difference between Fuji lens 23 1.4 and 23 1.4r?

I don't remember this thing having a second generation ..................................................................................................................................................................... Earlier there was an old 1.4 without wr.

The full name should be XF23mm f 1.4 R LM WR.

XF stands for high-end relative to XC, R stands for ring with aperture, and these two old 1.4 also have it.

LM is a new linear motor, which is more powerful than the old step focusing.

WR stands for all-weather, with splash-proof function, and can be shot in rainy days with a single-digit body. No matter how bad the weather is, I won't try.

In addition, by looking up the parameters, we can know that the recent focal length has increased from 28 to 19 cm. The weight has increased from 300 grams to 370 grams, and the length has also increased from 63 mm to 78 mm, and the appearance has naturally changed.
