Thank you! I used a humble canon rebel T3i. The lens I used was a nice portrait lens, it's called "the nifty fifty" and it's only $125 on amazon, which is pretty cheap as far as portrait lenses go.
For the lighting I got a 3 lighting umbrella set from amazon that was around $30. I see the prices have gone up to $50 unfortunately. I got 3 light stands + the 6500K lightbulbs that came with it. I used a black table cloth as a backdrop and that was all I needed!
The two cameras are very similar. Sensors and imaging engines are basically the same. The advantages of the 77d are more autofocus points, faster shooting rate, top LCD, and better video resolution- that's what you're paying for. The image quality for still images from both cameras will be very similar. The faster shooting rate of the 77D and slightly better autofocus might be an advantage if you're planespotting airplanes in flight.
That said: Better lenses on a less-expensive camera (especially one that has basically the same sensor and processing engine as the more-expensive version) will give better image quality over the more expensive version with a not-as-good lens. Lenses nearly always matter more than the camera if you're looking for sharp, clear images.
If I use this lens https://www.amazon.com/Canon-50mm-1-8-STM-Lens/dp/B00X8MRBCW on camera with 1.5 crop factor, will it be 75mm? Sorry for dumb question, I'm beginner.
The Canon has a 1.6 crop factor. A 50mm on a Canon APS-C camera will have the field of view of an 80mm lens on a full-frame camera-- it's a pretty zoomed-in look, short telephoto. Keep in mind that aperture is not affected by crop factor. It's still an f/1.8 lens on all platforms.
/u/MrGonghen - if I was starting out, I would get adapted lenses. Here's why:
Pros: access to thousands of Canon EF mount lenses - you won't have to buy new lenses if you buy or rent a Canon EF mount camera (e.g., Canon Cinema EOS, Blackmagic URSA, Panasonic LT, RED Raven), equivalent lenses cost less money (e.g., this $110 50mm f1.8) - autofocus is available with an autofocusing adapter - focal length reduction and an extra stop of light available from any Canon EF lens with a Metabones Speedbooster or Aputure DEC LensRegain.
Cons: Autofocus is slower with adapted lenses, Canon APS-C lenses are larger and heavier than equivalent micro 4/3 lenses
With a $600 budget, I would buy a $245 Kipon Autofocusing adapter and something like this $350 used Sigma 10-20mm f3.5 for Canon mount.
Here is an example shot with the G7 and adapted lenses, to include the Sigma 10-20mm f3.5:
Hope this is helpful, good luck with your lens upgrade and best of the holidays to you and yours!

You want a longer focal length than what you're using, and you can't really beat this price if you're buying a lens. It's known as the "nifty fifty" and it's pretty universally recommended as the second lens anyone with a DSLR should buy. Bonus: it can have a really shallow depth of field so you can take some great pictures with it too. Just be sure to use a narrower aperture for when you're doing self-tapes because you don't want your focal plane to be that tight.
