Your precious and honest opinions about differences between Fujifilm and others (Sony, Canon, Nikon)

I was a long-time Fuji X shooter. Had the original X-Pro1 & X100. Then went through a X-T1/X-T2/X-H1 progression. Had many lenses.

I'm also a passionate (but not pro) Landscape photographer, and, more recently, astro.

About 2.5 years ago I switched from Fuji X to Panasonic FF (L-mount). S1R, S5, and more lenses than I like to admit.

I will say - the files I get from the S1R & associated lenses are in another class, from a detail perspective. Colors are great too (I was always a raw shooter and didn't use the OOC JPEGs, even when I was shooting Fuji).

And the lens selection, is, IMO, a better match for what I do. For me, there wasn't much in it from a weight perspective given that I was using the 8-16/16-55/50-140 lens trio with Fuji. Yes, the Panny "Pro" lenses are significantly heavier, but their non-pro lenses compare very well to the Fuji red-dot lenses from both a weight and an IQ perspective. But yet if I want even better IQ, it's there waiting for me, if I can accept the weight (and sometimes I do). Also, if I want to cut back on weight, I carry the S5/20-60/70-300. Still not nearly as light as a minimalistic Fuji X system, but it's light enough for me and still has very good IQ.

And yes, I like PASM. Works better for me.

So overall I'm super happy I switched.  Even though I loved Fuji X.

Note that I'm not looking to pick a fight with Fuji X landscape shooters. It's mostly about composition and timing, anyway.

Cheers!
