Normally Robin Wong is overly enthusiastic about Olympus. His more subdued take on the new PEN-F should raise an eyebrow or two then:

On one hand, as an Olympus fanboy, I have high expectations in the new PEN-F, hoping that there would be a huge leap in the image quality from the new 20MP image sensor. I am sure I am not alone in this, and many Olympus loyal supporters are echoing my sentiments. Finding out that the image quality produced by the PEN-F is only slightly better than E-M10 Mark II on the whole basically toned down the level of excitement I was in when I was reviewing the camera.

At least he’s honest about being a fanboy.
