Didn't mean it that way but if you read some comments by some folks it is mainly if you don't shoot FF you basically don't know what you doing. It is always DoF and 6400+ ISO.
I think this day and age things have changed drastically. Back in the day not long ago it was a battle of Nikon shooters vs Canon shooters. Now the photography world discusses Mirrorless vs DSLR.
Just think how much crop sensors have changed!!! If you shot with a 40D or 50D and compare it to an 80D there's a big change in how the newer sensor puts "meat on the bones" with more rich looking files with more tonal depth. Older gen crop sensors appeared more flatter in comparison. Now Fuji and Sony are hitting the streets with great Mirrorless bodies that are almost as good in AF of a DSLR.
Seems more people are getting more "educated" and they know what they want in their gear. Now that crop sensor image quality is so good these days the "jump" for full frame isn't anything to brag about compared to many years ago.
Today I took my X-T2 out with a large crew of preschoolers to a class field trip. The image quality was truly fantastic shooting with the 10-24mm UWA and 16mm f/1.4. I'm challenging myself to see if I can use the fuji as a primary system. I absolutely find the fuji files to be extremely easy on the eyes and pleasant. Rich lush files great for viewing on an IPS panel screen or print!!! I will have to say the video capabilities of the fuji non graded is remarkable.
One thing I would say is that I still feel I can have great "3d pop" to the image shooting full frame with an f/2.8 zoom without throwing on primes. I guess my point is that there is some advantages of greater versatility in a fast zoom lens on a full frame. I cannot justify purchasing a $5k CDN Canon 5dmk4 but that camera would provide the full frame DOF and 12800+ ISO would provide extremely clean images effortlessly for incredibly versatility. Throwing on a 24-70L f/2.8 MK2 on a full frame still shocks me in how razor sharp and pop a zoom lens can provide. Some people may not ever need high iso performance but having a Camera capable of extremely clean images and shallower dof is a nice bonus for some users demanding that type of performance. Everyone's needs is different....
I'm not a sony shooter but I'm extremely curious if Sony mirrorless have any issues locking on AF in a dark venue like a dance floor during a reception. Fuji has still not met my needs in locking AF in low light. Since I'm a Canon shooter I've never ever questioned my 5dmk2 or 5dmk3 in locking AF in darkness while having a Canon external flash on shoe. So far with my Fuji with EF-X500 I certainly can say the fuji is not even up to my standards for that type of low light shooting situation. Even during casual outings I've found the red indication "NO AF" which I miss shots. I've always locked on virtually anything in almost pitch darkness while using focus assist on my Canon flash and canon bodies.
This is not disrespecting Fuji. Everyone has different shooting methods and needs/wants. I'm enjoying the fuji world for a high percentage of my shooting but I'm also fully benefiting keeping my heavier Canon bodies too.
