Unfortunately both things can be simultaneously true.
I seriously need to see some numbers to detail the advantages, and what it means to me as photographer. A bunch of people saying these things without testing is seriously hard to evaluate.
Just shooting with those Canon R5 guys the others, apart from shutter speed which has been addressed in the K-3iii I seriously couldn't find any observable advantage, beyond they din't have something as convenient as the DA 55-300 PLM which was huge advantage for me in both ease of panning and portability.
I actually asked what was better about the R5 than the 1Dx's they owned before and got a bunch of humming an hawing. Someone help me out here.
OK... so to begin with, let me just state that since I use both Sony A7II mirrorless and Hasselblad HV "SLT" cameras in addition to my Pentax gear, the points I mentioned about WYSIWIG, easier low-light shooting due to amplified EVF, on-sensor PDAF accuracy without the need for AF fine adjustment, and easier manual focusing through the viewfinder aren't quotes I've taken from reviews - they're based on my own experience.
Re the numbers... I'm not up-to-date on the performance of every camera, but we're seeing higher-end MILC models shooting at 20fps using fully electronic shutter. Does anyone really need that? Arguably not, but folks
are making use of it. As for size, see
this link to compare the Sony A9 MkII with the K-1 MkII - look at the different views front and side, the dimensions, and the weight (you need to scroll down for that). Lens-wise, you've got me - not because I'm doubtful of my previous claim, but because I'd have to trawl through all the lenses for various models to find relevant comparisons.
I'll say again, as I do many times in these forums, I'm a Pentax DSLR guy at heart, and a happy, satisfied one at that. I'm not looking to fabricate reasons why mirrorless is better. I'm just saying that
in my opinion (that's all it is - an opinion... YMMV), there are potential advantages to mirrorless cameras depending on the individual's use cases, preferences and priorities - and they're pretty compelling advantages if they happen to match your shooting requirements. DSLRs have different advantages... and they suit me for most - but not
all - of my own requirements. For a couple, I find mirrorless cameras
invaluable.
