Welcome,

The 24mm Olympus Zuiko 2.8 is probably the smallest and lightest 24mm lens that you can buy, is only 180g, 31mm long and the filter thread is 49mm. Is well built mostly metal and glass. Three versions of this lens where made. The one with H.Zuiko is not multicoated and it will flare and ghost a lot more than the 2 version made after that. The version that I own is the one with the multicoated glass.

The lens is compose of 8 elements in 7 groups, Olympus engineers where amazing to put all that in this small package. It is the perfect lens to walk around with if you like the 24mm focal length. The only digital cameras that I own are Fujifilm GFX on the GFX it becomes about 19mm. The lens vignette a lot, the corners are very soft even at small apertures but still fun to use and very easy to carry around. My version of the lens cost me around $100aud.

I don’t know if I will recommend this lens to be use on a Fujifilm GFX it is fun to use easy to carry around but it doesn’t have a lot of character. I think on a 35mm camera would be a very competent lens will vignette but nothing crazy and the extreme corners would be ok.

On my Infrared converted Fujifilm 50r it is very good I couldn’t get the lens to hotspot which is great because the GFX 23mm hotspot from f4. I’m not comparing the 2 but is an option to use as a wide infrared lens.
