Thanks again both of you for the input. Mine is the 100mm Non L I bought used with the 20D with compact flash and 8mb sensor, and a bunch of misc extensions and EF 75-300 and EFS 17-85. I bought it all for $650 a few years ago but it sat unused. So decided to buy the rest, to make videos with those lens so got a manfrotto tripod, M50 and its EOS to M adapter but these 3 lens are heavy, unlike my M 22mm f/2 and kit lens. I looked at Tilt shift lens but too expensive, (not sure if those tilt shift adapters are any good) I am a hobbyist so no way buying $3000 85mm f/1.2 lens, lol. I liked Canon pocket cameras since after I had an Elan film SLR in 90's for product photos in my business, then bought the first digital Elph on release in summer 2000 for $600 w/ 64 Mb compact flash card also $400 (expensive) at the time, and as the saying goes the "best camera is the the one you have with you". I really like Macro shots which my smart phones don't work for that. So I need to increase the aperture it seems and proceed with a rail system.
I have read this forum for a few months and felt at a dead end with my M series lens and the expense of R lens, hence why I bought a 6400 instead of R10 to potentially be able to use inexpensive Viltrox, Rokinon, etc 3rd party lens. Then first day using it I noticed the Canon M50 color is awesome, accurate and constant versus the Sony unless you adjust the light control on menus to "shade". I had this really nice purple flower I started to do close up's, it is like a rose but that changed hue on the 6400 to blue depending on camera position in side natural lighting. That was a shock. But Canon was always accurate as purple no matter the angle. Canon's menus are less complicated, but the Sony has way more configuration which is fine for tweaking but more than I need or want to plow through. I don't want to second guess and color correct.
