Looking to make a decision: Upgrade camera or upgrade lens?

Hello! I am a portrait photographer. I've been onto photogrpahy for 5 years now and I'm really for something new in my photography. I have 3 decisions. I currently shoot Ona rebel t7 and have an ef and efs lens for it.

Get a $500 Canon mark iii 5d and sell it when once again I am ready to upgrade.

Don't get the $500 Canon mark III 5d and get a full frame 75/85 mm lens. And prepare tk use that on my future camera.

Or wait and just purchase the 2k camera when I have the money (which is going to take quite a long time)

Firstly I want to remind you the Canon EF-S lenses will not physically mount on the EOS 5D Mark III. Some from crop lenses from other brands will fit, but of course there will be significant vignetting. So if you are going to pick the EOS 5D Mark III then you will only have the EF lens to use with it.

What is the motivation to change to the EOS 5D Mark III, what benefits will it deliver for your photography?

You mention selling the EOS 5D Mark III again when you next upgrade, if you are thinking there's another update one option is to take the plunge and go mirrorless now. An EOS R50 or EOS R10 body with the adapter will work with both your lenses and move you forward for future updates. One other idea is to select a used EOS R6 and use them with the EF to EOS R mount adapter. This lets you use both of your existing lenses, and gets you a brilliant full-frame camera with clever eye tracking for people plus it's amazing in low light. The EF-S lens can be used on the mount adapter with the EOS R6, but the camera will automatically select crop mode resulting in 8MP images. Personally I switched from an EOS 5D Mark IV to the EOS R6 back in 2020 and it was a good move.
