so I finally pulled the trigger on the Canon R8 because I wanted that full frame look for my trip to Tokyo next month and honestly im so excited to get out there but man the kit lens is just... its driving me crazy already. its so slow and the quality feels kinda mushy for what I paid. im honestly fed up with carrying around this cheap plastic glass that doesnt do the sensor justice. I need something thats great for travel but doesnt weigh a ton because were gonna be walking like 20k steps a day. ive got about 800 bucks left in my budget for one good do-it-all lens. what should I get for the R8 that isnt gonna break my back or my bank account?
