Sorry for confusion.
I shoot the A77ii and was heavily considering the A7iii. However I am adjusting to the idea of an A7iv for all the reasons concerning the LA-EA5 adapters, and other considerations mentioned here. I am ok with the 33mp of the A7iv and I am ok with the current 24mp crop of the A77ii. I am guessing your point about the relative proximity of mp in both of these cameras. However, some how I managed to mix the A7iv and the A7Riv in this regard. I shoot a lot of lower light and I think the A7iv would serve me better that the higher pixel A.7Riv. The versitality
in other regardsof the A7iv over the A7iii is considerable.
I am now as I have time looking at how many lenses I would purchase with an A7iv. Because of my low light considerations I was originally going to just purchase the FE 24-70 GM and the FE 70-200GG. My old CZ 24-70 did well enough on the close distance shots to not need a macro. I have a crop 11-17mm variable lens that I never have used. And on medium distance, shots of people (note I didn't say portraits) were good so it became a go to lens most of the time. Same for the Minolta 70-200 G as it did OK even with a teleconverter on longer shots. I can't say I specialize in any particular discipline of photography, but everybody likes as sharp as they can afford. Most of my images come from vacations - national parks and such, but I try to get good landscape images and like to get situation shots of people in the environment. I make photo books and slide shows with accompanying music for family and friends. I have 1500 recent Glacier N.P. and Olympic N.P. images taken with my RX100 vii and I think I will find it is not enough for what I am looking for. (Weight has become an issue). I will compare the RX100 shots to some of the same shots I took with the A77ii CZ 24-70 F2.8 in the next couple weeks.
So that's probably more info than anyone wanted to know, but I started out clumsily on here explaining my interest in upgrading to an A7 mirrorless, so this post may help.
Thanks to all for posting. This is an educational and fun forum to venture into. The number of available lenses for the E mount exceeds my quick comprehension, and I am now trying to make good decisions on a few of them. Like maybe an FE20-70G instead of the FE24-70GM2 and such. I do like bokeh and sharp with detail though.
