"Weather resistance".

Virtually no DSLR or mirrorless or bridge camera or point-n-shoot is fully "weather sealed". You should assume it's "weather resistant", at best, and take reasonable precautions to protect it from the worst weather conditions. Electricity and moisture don't get along with each other very well! A single drop of moisture in the wrong place can short things out and fry the camera! Don't risk it! (Note: There are underwater cameras, truly sealed for use at various depths.... But I don't think that Sony is one of them!)

As to condensation... absolutely NO. Regardless of the quality of the "weather resistant sealing", the camera will still be susceptible to that. Seal the camera up inside a plastic bag, then seal that inside a second plastic bag, before bringing inside and allowing to warm up. Don't unseal it for perhaps an hour, depending upon the temp differences. Otherwise, condensation can occur inside on the cold surfaces suddenly exposed to warmer air. If you have a bag or backpack full of gear, use larger bags to seal it all up until the temperature equalizes indoors. Lenses, flashes, etc. are also susceptible to damage from condensation. Even old fully mechanical gear, with no electronics, had to be handled this way. Condensation can make metals corrode and cause water spots on optics.

"Glove"

I don't shoot in ultra cold very much any more (moved to California, where it never gets very cold). But, in the past when I did, I used standard gloves most of the time and just slipped them off when shooting. During longer shooting sessions, I might wear very lightweight gloves underneath mittens or ski gloves, slipping the heavier gloves off during shooting, but leaving the thin "liner" gloves on. When it wasn't too cold, but gloves were still needed, I used "bicycle" gloves that are moderate weight and have built in "grips", to better keep hold on my cameras. But I was using film cameras with fairly large controls... not like today's digital with tiny buttons and dials.

Maybe fingerless gloves? Maybe those underneath heavier gloves or mittens?

Pockets and hand warmers can be handy, too.

"Batteries"

Out in the cold, be sure to take extra batteries. Store the extra(s) in an inside pocket where they will be kept warm. Cold greatly reduces battery capacity. However, they come back to life once warmed back up... So plan to swap them occasionally, putting the warm one in the camera while stowing the cold one in that inside pocket to warm it back up.

If the weather sealing is as good as Olympus and Panasonic, wind, rain, dust, cold, and snow will not be much of a concern any more. You can still have condensation issues, but that only concerns hot, cold, and humidity and nothing about weather sealing.

Congratulations on the purchase of your new "baby!"
You have several options here for you to explore. So let's get started with some simple information. What you need doesn't have to cost a boat load even now that you are strapped for cash.

Most cameras today are designed to be weather sealed. I said "most!" You can add another layer of protection and comfort against condensation by using inexpensive ziplock bags. Keep one or two in your bag for emergencies. Make sure your bag is water proofed. Add a linen napkin on the inside to absorb any wayward water drops. Finally, I have a handful of thumbnail sized dessicants. I went into a local pharmacy and asked if the pharmacist would like to save me some of these little gems. They are placed into a stock pill bottle to prevent moisture from damaging the pills inside. The pharmacist was very obliging and liked the idea and saves some for himself.
You can also purchase a RainSleeve. These "bags" will cover the camera and allow you to shoot in wet environments like Niagara Falls. I was the only one who had it on a recent trip there!

Photographer's gloves can get ridiculously pricy. Why? You could buy a regular pair of waterproof gloves made to prevent the cold from capturing "click bait." You can cut off the thumb top and index finger top for better dexterity. You could hunt around on Amazon or Ebay for gloves under thirty dollars. Many gloves have the tips partially cut and can be moved out of the way and kept in place with a tiny magnet inside. A wise investment.
Keep from losing gloves by keeping them together with a Cable Cuff. These cost about five dollars. Or you can spend about the same amount of money for a clip that holds your gloves together and attaches to a belt loop. I believe it is called "Glove Grabber Clip Holder."

Just because something is more expensive doesn't necessarily mean it's better.

I have seen ridiculous items that added the insult of being overpriced. Personally, I'm not big on spending over $100 on a specially designed "Parka" for a camera. I won't spend $80 on a specially designed memory card reader. Or for that matter, metal covered memory cards labeled as indestructible.

I hope you get my points but be wise that my suggestions can be used for a Canon 5D like myself, a Sony RX10IV like yourself or a Mayima or a Hasselblad.

Let me wish you

Happy Shooting!

I am in complete agreement. This is what a number of cold weather photographers recommend. In the winter of 2017-18, I was in Yellowstone with friends. We took three snow coach tours and I did a lot of photography. Each time, when boarding the coach, I use my plastic bag and experienced no difficulties, at all. The temperature was hovering in the single digits and low teens.

For that trip I used glomits, mittens with thin glove linings and mitten tops that would be flipped back to expose my fingers and thumbs covered by light material. This gave me the tactile control I needed while saving my fingers or requiring me to put on and take off mittens each time I wanted to shoot. These can be found at any large sporting goods store carrying any cold weather equipment. Hunters use them a lot up here.

Thank you, all, for great advice. I will surely use a Ziploc bag to protect my new camera from condensation because now I understand what weather-sealed means. On the "frozen fingers" problem that I experience here in northern WI, I think I have the answer. Long adjustable mitten clips along with super-warm mittens and hand warmers should work fine. Don't mind having my fingers exposed (the best way for me to handle and operate my camera) if I have a warm place to tuck them into when I am not shooting. Allowing the mittens to dangle (instead of trying to hold them with my teeth) will also make outdoor photography way more doable for the next *too many* months!! Again, thanks to the many who offered great advice! Love being able to jump on this site and get questions answered. Cheers!

Look at the ice fishing gloves at Fleet Farm ,you might find something to your liking, I just love that first morning after a heavy snow up there.

** squeeze out as much air as you can before you close the Ziploc bag

Yes, it is those early morning hours, when new snow lies 12" or more deep ... breathtaking. The pines, the river, the silence in the woods. I go out even it if is 0º F and lower ... and tell myself I am uber crazy. Will look at Fleet Farm. Going there soon. Hubby's favorite store – the man's mall!

I have the perfect solution. I moved from Detroit to So. Florida - no snow, no cold, no gloves, problem solved.

NormanTheGr8 Loc: Racine, Wisconsin

Now you have the opposite problem cold ac to hot humid 😁

As for moving out of Detroit, could never figure out why anyone would live there in the first place
