Look, I totally get the struggle with the EF-RF adapter. I hauled my 5D Mark IV all over Europe for a decade before switching to the R6. The first time I tried using my old EF glass on the R6 with that adapter, it just felt front-heavy and awkward while walking through narrow streets. If you want one lens that never comes off for a trip to Italy, you should look at these two based on my time with the system. 1. Canon RF 24-105mm f/4L IS USM
This is what I ended up keeping on my camera 90% of the time now. It fits your budget perfectly and the image quality is honestly stellar for a zoom.

• Constant f/4 aperture means you dont lose light when you zoom in for a tight shot of a statue or a face across a cafe.
• The weather sealing is legit. It saved me during a random downpour in Rome and I didnt have to baby it.
• Nano USM focus is near-instant and dead silent which is nice for candid street shots. 2. Canon RF 24-240mm f/4-6.3 IS USM

I bought this one for a trip to the coast because I wanted more reach for architectural details without carrying a bag.

• The range is incredible for travel. You can go from a wide street view to a tight detail on a cathedral tower in a second.
• It isnt an L-series lens tho, so you lose that constant aperture and some sharpness at the edges compared to the f/4.
• Its way lighter than carrying two lenses, but that f/6.3 at the long end can be tough once the sun starts setting in the piazza. For Italy, the 24-105mm L is probably the smarter play. Its built like a tank and handles the R6 sensor beautifully without feeling like a total brick in your hands.

Quick question, do you prioritize reach or a constant aperture for this trip?

• Canon RF 24-105mm f/4L IS USM
• Canon RF 24-240mm f/4-6.3 IS USM The L series has better corner resolution.

ngl i've been stuck on this exact same problem for like three months. i've been trying to find one lens that just works for everything so i can finally ditch the adapter, but it's been a total headache. the bulk is definitely the worst part of the switch to mirrorless so far and i still havent found a solid answer that feels right. quick question tho, are you mostly shooting in bright daylight or do you need something for those dark cathedrals and evening dinners? im trying to figure that part out myself before i commit to anything because i need something reliable that wont fail in low light.

Late to the party but this whole thread is 💯. Glad I found it.
