Conclusion from DPReview:
The X-Pro3 is a unique mirrorless camera, and will appeal to those who want a waist-level screen or an optical viewfinder experience. It’ll be a camera you either covet or don’t see the value of, but that polarization is the X-Pro 3’s defining characteristic, and some photographers will find it very compelling.
Street and enthusiast photographers looking for something a bit different.
Not so good for
Sports or zoom-lens shooters. Photographers looking for a do-everything workhorse.
What we like:
- Excellent image quality
- Range of attractive film/color modes
- Optical viewfinder gives interesting experience
- Electronic viewfinder further boosts flexibility
- Flip-down screen excellent for waist-level shooting
- Attractive, detailed 4K video
- USB charging is useful
- Faux film stock sub monitor is undeniably cool
What we don’t like:
- Optical finder doesn’t work as well with wide or long lenses as predecessor
- Obscured rear screen limits some styles of shooting
- AF point indication in OVF makes near-to-far parallax shift unpredictable
- Some lenses (particularly the F1.4s) aren’t especially fast to focus, undermining the the immediacy of street shooting
- Face/Eye detection mode a little prone to false-positives and requires input if your subject temporarily turns away
- ISO dial is more decorative than utilitarian
