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!
