Hell no, NOBODY on the planet did rant about the 5D4 because anybody expected "a camera that can shoot medium format quality images, with the speed of a Canon 1DX Mark II, and the video functionalities of a RED Weapon"!!!
People rant about the 5D4 because it doesn't have many features that cheaper (cheaper than what? d810 is around the same price, so is the a7r2. d750 is IMO not a direct competitor)and older camera products of competitors offer, like:
- Articulating screen not everyone wants that, in fact, many are very vocally against it - myself included.
- Silent Photo Shooting ????? normal shutter is pretty quiet, and the silent mode is quieter than the 5d3, not sure what more you want in a dslr
- EVF reviewing and filming don't do video so this is pretty useless to a stills shooter
- Sensor stabilization it is up for debate for sure what is better, IS in body or IS in lens. I'd prefer it in lens, but that's just me
- Pixelshift no need, not ranting about the lack of, didn't even notice it wasn't there
- Focus Peakingno need, not ranting about the lack of, didn't even notice it wasn't there
- Zebra no need, not ranting about the lack of, didn't even notice it wasn't there
- Fully assignable buttons actually, the buttons are way more customizable on the mk4, and tat new little nubby button is really nice
- Third wheel for ISO not really needed
- APS-C Crop Lens compatibilityreally???? this is a very old horse that's been beaten to death too many times. with so few EFS lenses, come on, you sell them off when you move to FF. Do the research and own the purchase
- Speedbooster Option ??????
- App installation please god no, that's what your phone is for - let your camera be a damn camera
- Hot Shoe multi use for audio etc stills focused people aren't complaining about this
- Thumbnail Videos stills focused people aren't complaining about this
- Video Log/Raw Mode stills focused people aren't complaining about this
- 4K shooting in real Full Frame stills focused people aren't complaining about this
- 4K shooting in any zoom range between Full Frame and the middle 8 MP crop stills focused people aren't complaining about this
- 4K in 3840 width stills focused people aren't complaining about this
- 4K with efficient codec stills focused people aren't complaining about this
- HDMI out in 4K stills focused people aren't complaining about this
- 4K 60fps stills focused people aren't complaining about this
- 240fps Video stills focused people aren't complaining about this
- Focus stacking mode this would be neat, and I can see DPRAW evlving to meet this need, but, it's still probably better to complete the stack on your PC rather than in camera
The worst thing is that Canon just did release their best flagship cameras with the 5D4 and 1DX2, that have to last until 2020 with a big gap in specs, as the follow ups of the 6D and 5DsR will hardly include anything of a long list of convenient and modern features. this is totally your opinion, many do find the camera to be quite awesome At the same time you can expect that Sony will come out with a new camera until 2017yup, and in 2018, and in 2019, and in 2020 --- I for one would rather have something with a little more lasting power, as opposed to buying a $3000 camera every year, chasing the greatest spec sheet that merges the best specs of the A99II and A7RII, who are both not having a nearly equally long list of missing features compared to the 5D4.
The times have changed. In 2008 the 5D2 was alone on the market with its set of features and offered (unfortunately by chance it seems) more than people expected, which is why the feedback was 95% positive. Now we have 2016, and subjectively 50% of all people are disappointed about the 5D4, because Canon still acts as if they just have to be a bit better than Nikon and nothing else, like in the last decades.
