Man, I just dropped a small fortune on the new R5 Mark II and now I'm paralyzed by the lens choice. I've been shooting Canon since the 5D II days so I'm not a newbie but this new sensor is showing every single flaw in my older EF glass and even some of my early RF stuff. My logic was that I could just stick with my EF 24-70 II and an adapter but the AF speed feels... I don't know, just a bit laggy compared to the native glass and the resolution is so high that I'm seeing soft edges I never noticed before.

So I was thinking about the RF 24-70mm f/2.8 but honestly its such a brick to carry around all day. I do a lot of hiking - actually going to Iceland in about three weeks for a big trip - and the weight is a huge factor. But then I look at the 24-105mm f/4 and I'm worried the f/4 is gonna kill me when I'm doing indoor candids or blue hour shots. Is the 28-70 f/2 the answer? Probably too heavy and way out of budget since I'm trying to stay under $2500 for the glass after the hit my bank account took for the body. I just want one goldilocks lens that stays on the camera 90% of the time without making me regret my life choices on a 10-mile trail. What are you guys actually using as a daily driver for this body...
