Why is it "clinging"....?
just relaying what others write. I have no issue with DSLRs, although I don't think I'll ever own one and think many current users would be equally well served by a mirrorless camera. I suppose that in the long run DSLR's will be a niche, but I think that's still at least a decade off, simply by virtue of millions of customers having already invested in them.
I doubt Fujifilm are going to make a 16-47mm F1.9 for it would be too big and heavy for their cameras.
The biggest problem for mirrorless is that Canikon are deeply entrenched in the pro scene with pro support and the AF tech. and the f2.8 pro lenses are a god send for many since the bokeh is effectively like a Fujifilm/M43 prime throughout the focal length. I doubt Fujifilm are going to make a 16-47mm F1.9 for it would be too big and heavy for their cameras.
they got speed AND low light performance while Fujifilm have the low light and M43 have the speed.
They don't need FF sensors, they just need to improve the rest of their tech, get those pro lenses out and have pro support, the rumoured 24mp X-PRO2 would help those who want to print larger or need the resolving power.
If you're happy with it, that's all that matters. I've spent a LOT of time with various Fuji models, with the RX1, with the D610, and Df. There's a significant difference. I haven't shot with the D810 or Sony A7R or experienced that 36mp sensor, but it's very very similar to the 24mp sensor in the D610, RX1, and A7 in everything except resolution. The Df is sort of a low light miracle but doesn't have as much DR at low ISO. Whether the differences matter is obviously an individual call, but they're real...Can't see an advantage in the image processing of an A7 sensor versus a Fuji X-E2, so I'll need no FF-Sensor of them. And I would have to buy a lot of new lenses, if they would present it
