Here is my "professional" opinion:

Whenever a new camera line or series is announced or a new trend arises, to me it's just a bunch of confusing model numbers, claims, and arguments. Some of the arguments are from experienced people and some are just useless technobabble, extracted from someone else's reviews. And, of course, there is all the advertising hype.

That is, until I SEE the camera, lens, or accessory, in person, hold in my hands, put it to my eye, and FEEL it. It is ergonomically suited to my shooting methods or level of dexterity. Can I apply it to the work I am doing? What will it enable me to do that can not do with my present gear? Of course, since photography is my BUSINESS, is the investment justified, and will it pay off in efficiency, production, and/ or customer satisfaction?

If photography is your hobby or avocation, you can still analyze your potential purchase, except for the business aspect, with the same criteria. If you have an unlimited budget- hey, you only live once! If not, think carefully about your existing lens inventory and other such required adaptations and potentially MORE additional purchases.

Use to be, in ancient times, a top-of-the-line camera set you back !$1,000, maybe $2,000.nowadas it can be 10 times those figures. Ordering such an instrument online, and having it dropped off by UPS? Forgetaboutit! Having to send it back if you don't like it! Where do you live- in Antarctica? Find a local dealer, take a drive, get a demo, and make up your own mind!

Many years ago, I took a course in salesmanship. Very interesting! One of the more impractical "selling points" the instructor pointed out was the "pride of ownership"! With cameras not good! Well,nowadas, there are not as many "off brands" or camers for strange places. Most of us will buy mainstream brands and models. I always took the attitude that I did not care if my camera was "made in Africa by the Ants, as long as the held up and worked reliably. Keep that in mind, and don't be influenced by what's "trending"!

Bad gas? Take Gas-X or Pepto Bismol. Well, there is a generic that is cheaper known as Bismuthsubsalicylate but it doesn't taste as good-UGH! They both look like that pink Calamine/Benadryl lotion, so don't drink the wrong stuff!

Up front I will admit to having a bit of GAS as part of my motivation. I've been a moderately serious amateur since retiring 15 years ago. I started with a Nikon D60 then moved up to a D300S and settled on twin D7200s several years ago. I also have a D500 but haven't used it in the 3 years since I purchased it because the controls and settings are simpler (at least in my mind) on my trusty D7200s. My walk around kit has the D7200 with a 18-300mm lens. When I need or anticipate needing more lens horse power, mostly for wild life (I live on the Maine coast), I grab my other D7200 which has the 200-500mm always attached and at the ready. When I'm on a shoot, I virtually always have both cameras with me. I'm am not a technician by any stretch but I have a knack for decent composition so sometimes I hit the jackpot and score a great capture. I've been published a few hundred times in our weekly county newspaper and have been in magazines and tourist pamphlets published by the state. I've also received recognition a few times from the New England Newspaper Association, but mostly I'm just a retiree who loves shooting in RAW and doing post-processing in Lightroom & sometimes Picasa, and I get my kicks from the Likes on receive on my FB page when I post a good image. I'd like to purchase a new rig, mostly because I can, and have pretty much convinced myself that a Sony Mirrorless A7III with 24-105 lens could keep me busy for a while, and will likely be as good as, but not as heavy as, a Nikon D850 in combo with one of my other Nikon DX lenses (I have several). The D850 has been in my headlights for a while but I'm inclined to try a lighter weight rig. What say you folks who've considered or done a similar transition already?
