直接看dpreview_com网站的结论吧，要对比，也没有K1啥事吧

Compared to its peers

Hasselblad X1D 50C: Even in 'rangefinder-style' format, the 50R is larger than the Hasselblad X1D but that's about the only way in which it loses out. The decision to use a focal plane shutter means the Fujifilm avoids the angular bokeh that affects most X1D lenses as you stop them down, while also helping keep the Fujinon lens's costs down. The 50R is compatible with enough high-speed flash sync systems to mean you probably won't miss the Hassy's leaf shutter. The Fujifilm is easier to operate, has longer lasting batteries and delivers beautiful JPEGs, as well as costing less.

Canon EOS 5DS R: The Fujifilm's sensor is larger and adds less noise than the Canon's does, which give it an edge in image quality in a range of situations both in and out of the studio. The Canon is faster to focus but the Fujifilm again offers a benefit in terms of precision. The Fujifilm should capture every tone in the scene with a little more light and a little less noise, and its larger sensor is less demanding on lenses. The Canon is part of one of the most extensive lens systems there is, even if you will have to be selective about those lenses to get the best out of the camera. You pay a lot for the difference but there will be a measurable difference in favor of the Fujifilm, if you want or need it.

Nikon Z7: The Nikon Z7 is perhaps the most troubling competitor for the 50R. Its ISO 64 mode lets it tolerate and capture similar amounts of light to the Fujifilm, which narrows the gap in terms of non-lens IQ aspects (richness of tone, dynamic range, noise) to nearly nothing. The Z7 is, of course, a much more flexible camera, whether in terms of burst speed, AF performance and video capabilities. The Nikon also has in-body image stabilization and a more extensive flash system. The GF lenses do look extremely good though, and will continue to work when Fujifilm moves on to 100MP, which it'll be harder for full-frame to match. But don't expect a significant difference in most aspects of image quality between the 50R and the Z7: your preference between 4:3 and 3:2 aspect ratios will have more of an impact.

Fujifilm GFX 50S: The GFX 50S is the other significant rival to the 50R. It's not that much bigger but its additional grip and controls make it a nicer camera to spend time shooting with. Image quality is, as you might expect, identical, as are most of the arguments in terms of features. But the 50S's larger viewfinder, dual-axis tilt screen and dedicated controls all make it nicer to shoot with.

Conclusion
The Fujifilm GFX 50R brings medium format digital photography down to a more attainable price point than we've seen before, and does so while offering exceptional image quality in a reasonably compact yet well-built body. The ergonomics suffer a bit from the smaller grip, and some competitors with smaller sensors suffer only a slight image quality hit while being more flexible overall. That said, the GFX 50R remains a joy to use, the images a joy to view, and it's an excellent way to get access to Fujifilm's lineup of GF medium format lenses.

1. 50R的不理想. DPR这图上, 几处有红色等疑似"坏点"?
2. 50S的发红. 早有所知.
3. Z7的有条纹. 也是周知的戏称"条纹门".

用了K01尝到了单电的甜头

如果宾得肯出后续机型，我也不至于投入M43门下。。

即便如此，我的K01和DA10-17都依然没舍得出掉，时不时的带出去拍几张

晒下你的器材，让屌丝宾得中画幅用户摩拜下。

手动镜头就不要拿来滥竽充数了！要这么比，你宾得能用的镜头，富士的中画幅都没有问题，加个转接环都能用，反而，富士GFX50S/50R能转接用的镜头，你宾得645Z只有望洋兴叹的份了

不是怕影响销售原因，价格差和像素多少的定位区别很大的，不存在影响太大的情况。还是各方面条件决定了推出时间。

CMOS供应决定了可推出的时间和机型。并不是相机厂想咋地就咋地的。像素增加不配比也不是相机厂能自己决定的。

50MP VS 100MP可能是将来的两种产品定位类型，二者并不是取代或升级关系。即普通低像素型和高像素型将并存，各自走自己升级路线。

这方面前路祝贺最厉害。K1口水流了8年了还没买呢。抗战都结束了。

富士龙的镜头素质一点都不比你宾得的差！富士中幅现在还需要靠转接别家的全幅镜头来过日子？苦逼屌丝买不起原厂镜头才这么玩吧？

其实就是一个新，一个旧
