Canon RF 24-105mm f/2.8L IS USM Z to be announced this week

I have been on the fence for months now about this lens. I have the kit F4 lens and really like it but am really wondering if the 2.8 is worth the money and the weight it brings. Anyone have both that can comment on how the 2.8 compares to the f4 beyond an extra stop of light?

I have both. The f/2.8 is stellar optically, though if you're of those people who can't stomach required correction of distortion you should pass on it (the corners are black at 24mm before correction). The f/2.8 is noticeably better than the f/4 version from an IQ standpoint, though IMO the f/4 is pretty good. The f/2.8 lens handles very well, though it is significantly larger than the f/4 version. I use the f/4 version for travel and the f/2.8 version close to home.

Thank you. I am not one who has issues with image correction. I may convince myself to do the same as you and pick this up. The primary use for me for the 2.8 would be when I'm shooting motorsports or motorcycles, as there is almost always a transition to night for these events, and for things like the GS trophy qualifier, I am often very close to the riders, which renders my 70-200 a bit too much zoom. I would also use this on my R5M2 and shoot video at the running events I shoot.

Just order the 24-105 via Internet, and when it gets delivered, tell her it's a lens you've sent for repair.
Believe me, it works (provided you have a secret bank-account) ;)
Yep, I can certainly second this. My wife and I have a joint account but with her being a banker, I was constantly having to listen to the criticisms of spending money on things I wanted so I decided to start my own business for extra income and set up separate accounts for that. Once I did that and started buying out of those accounts instead of our joint account, the noise subsided significantly, now I tell her it's a lens coming back from repair (did this Friday for my 70-200) and it has made life much easier. Your mileage may vary.

In my own case, it's a well proven method.
In 2024, I've had 5 lenses and one camera "back from repair", and not one single question asked... ;)
But I also sold a few EF lenses, replaced with "repaired" RF ones.

I do hate doing this, but the signal-to-noise ratio becomes quite intense otherwise. She really does not have a lot of ground to stand on as I am spending my money instead of our money (she has her own money as well), and I am taking a lot of pictures of our son running.

I usually buy mint-used, and take my time to get a good price. I then sell mint-used or close to it and again try to get a good price. A lot of this equipment can cost VERY little to own, in terms of cost per year. If you want the latest bodies (me, at least for digital computerized bodies, though I still see advantages in a Leica M3 over an M6 for film) this doesn't work, but I'd recommend anyone to buy an R5MkI right about now, just shockingly cheap given that the actual picture itself is in theory as good as the MkII.

As to the "wife" aspect I've made a good track record of buying used synthesizers and reselling them, usually making some pretty good money on them. (Often all I'm doing is cleaning them and taking a lot better photos of the instrument than most sellers!) She accepts that it's not a business per se but at least not a cost center in our lives. I'm honest that photography is some cases is the same (e.g., the 24-105/2.8 that's been on the market and available now used) and in some cases does cost a bit (e.g., you can lose $2500 by trading an R5 up to an R5 MkII, say, so that's about $700/year or $2/day).

Well, that is certainly an interesting strategy you have there. I tend to buy everything new, but have the benefit of writing the costs off on my taxes since I have a business (IT business primarily, but I have a photography business that I umbrella under my IT business). I am sure my wife would understand this. However, she's a minimalist, and I am not. She gets upset when I get more stuff.
