If just one lens, the 24-105 is the one I would go with. If we get to go to Hawaii this November, I will be taking the Olympus 12-100 f4 Pro IS (24-200 in 35mm terms). Nearly two weeks in Germany and 99.9% of my shots were with that lens. The 105mm will be a little short for some wildlife and distant shots. But the 16-35 f4, great for interiors and architecture, will leave you wanting at some point on your trip (holiday). With the 24-105 on a FF camera, I would not have many reservations traveling with just one lens. If you are a good photographer, creative enough with how to get around most limitations, you can get away with traveling with just that one lens easily.

No operations or replacements but not for lack of trying with my left knee.
1. Vietnam - ran into a steel stake in the dark (and yes, it was at a dead run) and laid the knee open. At the base infirmary I had two medics arguing over if it needed about 6-8 stitches or if a good bandage would work. Doctor came by and asked me, I took no stitches, dressing and a giant ace bandage wrapping until it heeled, good thing I worked in the Tac Ops center and could sit at a desk for a couple of weeks while it healed.
2. Work, in a supermarket while in college - came around a corner carrying a 48 can case of veggies and someone one had let their kid play with a whipped cream can, slid a couple of feet but lost my balance and landed with all my weight on the knee, kept working until end of shift with the pain. Woke up the next morning to find it had swollen etc. while asleep and the pain got me by surprise - I screamed. Doctor said wrap in ace bandage and either rest & take pain pills or put up with pain and limp - it was finals week at the university so I limped. It was just sore and bit of a limp by the weekend when I was back at the market - they let me work the liquor department for the weekend so I sat on a stool and checked out candy, tobacco and booze for two days.
3. Coming up to my driveway on my motorcycle and a kid on a bicycle cut in front of me = I could run him down or lay the bike down on my own leg, I laid the bike down and the little snoot laughed and yelled I didn't know how to ride a MC - maybe I should have run over him. Limped for a few days and scratched up the paint on one side of my bike.
4. Over extended the left knee climbing off a locomotive at the railway museum - ace bandages, pain pills and crutches for a month.
5. Healed enough I was just carrying a cane "just in case" and I was late to a department meeting at the high school so without thinking I turned to take a short cut across a raised flower bed (18") and over extended it again stepping up - I heard it pop so another month of healing.

6. And since I developed the habit of using only my right leg when stopped on my MC (gave it to charity a few years ago-my wife had been after me to do that for a long time) and freezing on my right leg and playing crane standing on one leg if the left suddenly decided to give way I put a lot of strain on my right knee so that now every so often it twinges to let me know it might join the left one in going on strike.

Take your 24-105mm f4 lens as your most versatile single lens. I have owned 24-105mm lenses from Nikon, Canon, Sigma and Sony for my various camera bodies over decades and despite having wider and longer lenses and faster max aperture prime lenses in my kit, the 24-105mm f4 is my most used lenses, especially for travel.

FYI I presently own 13 E-mount lenses from 10mm to 600mm from Sony, Sigma and Tamron, and yet my Sony 24-105mm f4 lens gets used the most of all of them.

(assuming Ztc is a typo should be Zfc ... )
28 should be perfect for an APSC normal, almost exactly the diagonal. The FF Sony 28/2.0 is rather compact and is more often serving as the normal on my a6500 than as a wide in the a7XXX.

But the great thing would be a 28/2.0 scaled physically smaller for the Zfc, or maybe a 28/2.8 pancake. Fuji has a nice version of that. Lumix has their 20/1.7, again same FoV. Compact 15 and 65mm would finish a cool APSC trio around a fast 28 for the Zfc.

Cool as that might seem, with no OIS and no IBIS it won’t be on my wish list. I have FF and m4/3 retro kits and they both have IBIS :-)

Thank you for your service. I did not serve during Nam, but I worked instead for the US Dept. Of Energy doing research. I continued in this area the rest of my career, although also taught grad school for over 30 years. I worked in the major labs in the US and Europe.

Almost all my knee problems where due to skiing and racing. I only took two bad falls, one in France, and the other in Csnada, ending both in knee operations. The ski chattering on snow and ice creates vibrations which breakdown the knee tissue between the joints. Once that happens, you have bone on bone. You understand the problems well.
I hope you are doing well. I have my moments and understand the wheelchair or walker routine.

Take the 24-105!

Very popular. I’ve used them for years on the job. But for myself, off the job, I like a 35 or a 45.

Maybe a good way of looking at the OP’s dilemma is to ask whether holiday pix is much like a job or is it truly recreational.

On the job you pack the zoom and make sure you shoot everything six ways from sunday. But for pure recreation you pack sparingly, your lightest body and a single small lens to shoot whatever comes easy ... and don’t sweat the rest !!!

No question, majority rules for only one: 24-105mm.
The 50mm would be a good esecond one if you might need low light images.

lightyear

24-105 and raise the ISO in low light conditions.

I tried skiing for a few hours one day. After setting a new world's record for the most falls in the least time & distance + getting altitude sick due to my asthma I spent two hours on oxygen in the ski patrol clinic reading a book. Then I got my cameras and went back to taking pictures of the kids.
Jon is special needs and skied with "Adaptive Recreation" up at Big Bear and did Special Olympics for several years and Jasmine took lessons to keep her busy while her brother did that and on the second day of her lessons she had advanced to a two kid class with an instructor that was taking them on Black Diamond slopes. Then the Adaptive and Special O people made her a pair buddy with her brother to keep track of him on the slopes. Being a petite little thing she didn't have the weight to keep up with him as far as downhill speed went - that really upset her because otherwise she could sky circles around him without even trying hard. Being "frugal" she did like the fact that being a "buddy" they gave her a free lift ticket good for the whole weekend.

I agree with your approach. I prefer going lite for travel. I like my 35mm f/1.4.

Doesn't the EOS-R go up to like 40,000 ISO?
What's it perform like at, say, 16,000 ISO? Enough to make up for your low light lens?
I too have a newer Nikon Street-sweeper (24-120/4) and never went up above 8,000 ISO in super dim rooms - at night.
Unless you're looking for super bokeh portraits on the fly, your kit lens should be fine for travel.
Then if you are, I'd take the 1.8 in a pocket just for that.

Problem: There are things a 35 won’t do.
Solution: Don’t do them.

I agree with you. Sometimes I cannot get a longer picture. I do not shoot wildlife, usually landscapes, old buildings and street pictures when I travel.
