Many vintage lenses can be adapted to Fujifilm's X-mount cameras, opening up some fun and affordable options. Here are a few of my favorites:

1. Minolta MC and MD series - These 1970s-80s lenses offer great bang for buck. The 50mm 1.7 is a sharp, compact prime and affordable at around $50. The Rokkor 85mm 1.7 has gorgeous bokeh for portraits. Just watch out for lens coating peel issues on some copies.

2. Canon FD - Lots of fast prime and zoom choices. The Canon FD 50mm 1.4 is very sharp wide open with pleasing bokeh. The FD 85mm 1.2 L has a legendary dreamy look. Build quality is excellent but they can be pricier.

3. Olympus OM - Compact, light and sharp lenses perfect for travel. The 50mm 1.8 "Zuiko" pancake is a winner. The 28mm lenses deliver excellent wide angle views. Great mechanical feel in use.

4. Pentax M series - These tiny Pentax-M series primes around 40-50mm have outstanding image quality in a pocketable form factor. The 40mm 2.8 "pancake" and 50mm 1.7 are affordable favorites.

Remember to get an adapter to fit the lens mount properly. K&F Concept, Fotodiox and Techart make good adapters.

Canon FD and Canon LTM lenses are my favorite vintage lenses.

For landscape photography on Fuji, it's hard to beat vintage Nikon Ai-S manual focus lenses. The Nikon Nikkor 24mm f/2.8 and 35mm f/1.4 are super sharp and render cleanly on Fuji's X-Trans sensors. The 105mm f/2.5 is also stellar for compressed landscapes or for macro work. Nikon made their manual lenses up through the 2000s so they're easy to find and very well built. Highly recommended if you shoot a lot of landscapes on Fuji.

I love Helios 44-2 lenses. A good start for vintage photography.

Helios 44-2: Known for its distinctive swirl bokeh, this 58mm f/2 lens is a favorite among portrait and artistic photographers.
