Let's Talk about the SHORTCOMINGS OF THE CANON EOS R5 : ( as compared to 5D4,Panasonic S1H,A7R4,Z7 )
1. No dedicated buttons for Mode dial , button for switching between photo & video mode, ( in the 360 render of the R5 camera cannot locate either a dedicated ISO button or AF drive button ).
It has less buttons overall as compared to 5D4. Thumbs down
2.
Megapixels : R5 will possibly have 40 megapixels (which is very less in 2020, at least 45 Mpx is a must) ...Nikon released D850 in 2017 with 45 Mpx , now Z7 in 2019 with 46 mpx, A7r4 can do 61 mpx. Canon doesn't have the DR of the Sony's & Nikons.
So R5 lags behind the competition in photo specs.
3. Possibly the R5 will not have 10 bit internal video like S1H , or record externally 10 bit like Nikon z7, z6. S1H leads in video specs hands down.
So R5 lags in video specs as well.
4. Possibly No anamorphic lens support like S1H. R5 lags
5. S1H can do dual ISO for cleaner video at higher ISO. R5 lags here too.
6. S1H is NETFLIX approved & imho R5 won't have those specs for NETFLIX approval. R5 lags.
6. can't do ISO 32 & ISO 64 like the Nikon Z7 when you want shallower depth of field in bright light.
7. Canon has not talked about the battery life.
.in all probability it will take fewer shots per battery charge as compared to Canon 5D4.
8.
so the ONLY saving grace that Canon marketing found for this camera was that to give it 8K !!! ))
if you take out the 8K from the equation what does R5 have that the competition doesn't already offer???
Further, imho that
8K will come with at least a 2x crop & 8 bit 4.2.0 codec. So basically that will be a gimmick ...not for Pro's. Not sure whether the 4K will be with crop of Full frame either. Also possibly no live AF tracking in 4K or 8K modes. Canon has NOT revealed anything on the codecs. is it 8bit? or 10 bit? or has 12bit Raw like C200. Internal 10 bit in 4K is a must in 2020. what about RAW video codec ?? it doesn't seem to have.
RAW lite a must for video in 2020.
Canon is solidly lagging behind the competition by at least 2 years in Mirrorless...it is releasing cameras with specs which the competition already released in 2017 on wards.
So do u think R5 is the ONE which will destroy the competition in 2020 ???
