I just bought this Canon R7 because I wanted to take pictures of birds and maybe some bears when I go to Yellowstone next month but everything looks like a tiny tiny dot. I am so frustrated because I spent all this money on the camera and now I find out the lens it came with cant even see across a field. People keep talking about 100-400 or 600mm and mount adapters and I am just totally lost with all the numbers. I only have about 800 bucks left in my savings for this so I cant buy those giant white ones you see pros using. Is there anything that actually works for a beginner that wont break the bank?
honestly you should just grab the Canon RF 100-400mm f/5.6-8 IS USM and call it a day. i would suggest avoiding those cheap third-party adapters because they might mess with your autofocus speed. be careful with the aperture though since its kinda slow... you might want to consider bumping your iso when the light starts fading in the woods.
