Well-spotted on the misinformational summary of the EF135/2. Great lens it was, but round-apertured and weatherproof it wasn't!
Totally off-subject but curious why the f/2.8 AND f/4 zooms? At least on the wide end I can't imagine why one would have both. I only shot professionally a few years in the 90s but given how little I earned I wouldn't have gotten the 2.8 primes if was trying to make a living today. (Maybe you're just a lot better than me!) If I were trying to work as a photog today I'd try to work f/4 zooms, plus fast primes when I just absolutely couldn't sell an image unless I had more bokeh. I had f/2.8 in the 90s of course, when I needed it for AF, and when saving even a stop of film speed was visible in a small print or film scan. (ISO 800 shots looked like crap even when publisher was only printing something 3"/7.5cm wide.) But even then, I also got a lot of shots I couldn't sell due to bad DOF exacerbating slightly-inaccurate focus and lower resolution at f/2.8 at least with the lenses of that era.
Simply put, complicated purchasing strategy and finding deals I couldn’t pass up.
Short version: the f/2.8 are my main workhorse lenses and the f/4 lenses play a key role for real estate, travel, and as a ready to go backup at all times.
Long version: the RF 24-105 came in a kit with my original EOS R. I learned my lesson from the past that the 24-105 will always remain in my kit because it’s far too useful. In EF mount, I always had both as well. In 2020 (yes, a job during COVID!!) I was using the EF 24-70 at that time and made a bad call on a job in California where I packed the RF 24-105 instead. Sure enough, I found myself indoors and in darkly lit situations on several days. Seeing that I was on the road in California and didn’t have my selection of primes on hand, an f/2.8 zoom was helpful - particularly with wide angle low light. My friend and creative director for the job lent me his RF 24-70 f/2.8 and I was entirely shocked with how great it was - especially its minimum focusing distance. Some of my absolute best shots from that day came from that lens. The plan was always to progressively transition over to the RF mount and sell my EF lenses, but I was more eager to do so after the performance I experienced. After I got home, I located one in like new condition for less than $1800 with the original box. Had to get it. I use both regularly for different jobs and they have different roles.
The RF 14-35 was preordered and I promptly sold my EF 16-35 f/2.8L III after it arrived. I don’t exactly remember why I bought the 15-35, but my records also indicate a seriously good used price in like new condition with box for $1800 as well. I didn’t use f/2.8 very often with an ultra-wide lens, but that has absolutely changed. I now use the 15-35 and a 50mm or another prime as my combo when I cruise the pits with 2 cameras. Day or night, the combination works great. The 14-35 is a great lens, but I may end up selling that one at some point. It’s currently relegated to exclusively being a real estate lens for me. That area makes me a lot of money so, for now, I can justify having both. Plus if something happens to my 14-35 (which balances on a gimbal) at a listing, I need to be able run home and grab an ultra-wide to shoot a listing immediately after on the same day or the next day. (Unfortunately, I can’t use Fuji to shoot real estate or automotive as a main camera when using strobes and remotes.)
Nearly all the events (primarily races) I cover span the course of an entire day. Having zooms that can gather the most light make everything better. It’s a single stop but, in practice, it means a lot more. It men’s flexibility in shutter speeds, cleaner noise without processing time, sharper overall images stopped down working with strobes, the list goes on. The secondary reason is always having zooms ready to go for work. I’m a CPS Platinum member and even with overnighting repairs and loaners, that doesn’t always work with travel and tight schedules between jobs. I will often fly home on a Monday and be flying back out on a Wednesday. Or, in the case of last September, I was home for a total of 6 days. Not a chance I could have or would want to deal with the repair and loaner process then.
