Please Disregard This Post

Not sure which forum I should be on, and will welcome suggestions if there's a better place to go. Currently own 2 NX500 cameras and want to upgrade to a mirrorless with an EVF, fast auto focus, better low light capability, a fairly user friendly menu system. I love birding and all nature, want to go from my 50-200mm lens to a Tamron 150-600mm.

My first camera consideration in my price range is the Sony a7 lll E mount which is said to be faster than the a7r. Spoke with B&H today and they suggested the Tamron EF mount, and a Cannon to Sony auto focus adapter, but they said it would slow the auto focus a bit. If I got that lens I could also get a Cannon to NX adapter for my 500, even if only for manual focusing, which I use a lot on the 500.

If mulling this around, I decided to check into the Cannon EOS RF mount camera which is in the Sony a7 lll $ range. Reviews say it has a very fast autofocus, but in comparing the two side by side, it is very difficult to know which camera would better suit my priorities listed above. I have handled the Sony and I don't particularly like the menu system and the viewfinder seemed dull (looked at it in Best Buy lighting.) I know little about the EOS R, except what I read this evening.

Does anybody have an opinion on my two considerations or suggestions on what might be a good transition from the 500 that would accommodate the Tamron? The NX500 is my first non point and shoot.

Thanks!

Are you sure you want to do all these and go full frame? Bigger heavier and more expensive lenses?

Going tele is easier (cheaper and with a lot less weight) on a smaller sensor.

Maybe going m43 is a good solution.

Every Sony except the A7sIII has terrible menu and operating system and subpar ergonomics.

I would be waiting for the A7iv if I have to go Sony (better O.S and touch control implementation,plus even better ergonomics), or the rumored new Canon R cheap camera (just a rumor until now).

There is a rumored Canon RF APS-C camera coming also, remember, the smaller the sensor the easier is to go tele!

Another good/cheap solution is to go with an Canon M camera and the native EF adapter. Similarly small and light to the m43 cameras, cheap native lenses and probably better AF than the m43 ones.

Actually, I am not sure of anything right now. I have almost decided against the a7 lll for the reasons you suggested and then some, and have lowered my lens sights to a Sigma 100-400 instead of a HEAVY 150-600. They make one for Sony e mount and for Cannon. My cheap solutions were my 2 Samsung NX 500s, both of which developed problems in less than a year of use. Great cameras until they aren't . . . light in weight, excellent color, cheap lenses, great menu systems, and sharp results once you learn how to use them, but not fast enough, and low light situations can get pretty noisy.

If I do go for the Sony, it will be the a7 lV, so we are on the same page there, or the Sony Cyber Shot RX10 when the V comes out, but need a lot more research on that one. I have heard great things about it, and the Zeiss 24-600mm equivalent focal length lens sounds real interesting.  The V is supposed to have a friendlier menu system, but not so sure about the color science.  I might consider a Cannon, but a whole new ballgame for me, and honestly, I don't know where to begin.

Thanks much for your input. Appreciated!
