Canon announces the Canon RF 10-20mm f/4L IS STM

Personally, I love the RF 10-20/4. I had the EF 11-24/4 and often left it at home because of the size/weight...the 10-20/4 is far more carry-friendly and means I don't have to skip taking some other lens as I often did with the EF 11-24/4.

However, I can't see it having much utility for your use case. Unlike you, I shoot landscapes (and serious architecture, but for that I'm typically using a TS-E lens). The only times I've had people in shots with the EF 11-24/4 or the RF 10-20/4 are a limited number of situations where I wanted to capture people and space and needed to be close to the subject(s), or indoor shots of large groups in small spaces. Examples are my kids in a prison cell at the Eastern State Penitentiary or a shot of ~40 employees inside the company cafeteria (because we needed the shot that day and it was pouring outside).
Sounds like you understood my doubts, thanks for replying ;)

I have handled this lens before, it’s not like I’m looking at 10mm for the first time, but I never took it on an assignment, this is the first time I have it at home, which obviously is a little different. So far, I’m seeing perspectives of my home that I had never seen, and that’s fun, but it’s not work.

I can imagine some criative uses for this lens, such as:
— Group shots of people interacting with the camera (the kind we usually see with fish-eye lenses);
— Extreme-wide views of rooms like wedding venues, concert halls or halls;
— Extreme-wide views of concerts from the pit (though many concerts I photograph do not have a pit, because often it’s classical music);
— Someone walking a room and me using the wider angle to make the room huge and the subject miniscule

However, I believe 16mm could be enough in most of these scenarios and, to be honest, I don’t shoot at 16mm that often, its use constitutes less than 10% of my photography.

I’ve had situations, at weddings, where the 16mm could not autofocus due to low light (usually at the dance floor, when lights are dimmed). I suppose it would be a lot worse with this 10-20 (I’m talking One Shot AF).

I bought the lens for the price, and because I know I can profit from it. Now that I have it in my possession, I’m just trying to make sure I won’t regret selling it, because definitely I’ll never see this price again.

Well, it's definitely a fun lens... Whether that justifies keeping it or selling it for profit is, of course, your call.

Nah, work comes first :)
I'm happy with my 28 and 45 or 50 1.8 for personal stuff. My fun with photography doesn't need red rings 😝

I'll play around with this for a few days, maybe this weekend, and then I'll make a decision but, most likely, I'll stick with the plan and sell it. I don't think this would add much to my work, It seems to be just too wide.

Follow-up:

So, I the took the lens for an assignment, on Sunday afternoon, but saw nothing really useful in it (to me, that is), so I packed it up nicely on Monday morning, and sent it away in the afternoon.

It's a really nice lens, the form factor and working mechanics are awesome, but it doesn't really add much to my work, is just excessively wide.

Thanks for brainstorming @neuroanatomist
