In the small chance that I buy a new Nikon, the logical choice is the Z9, but it’s too big, too heavy, too complicated, and not what I want to carry around with me. Yep, I could get better specs from my D750, but I’m at my brother’s home on holiday, and I only brought one camera kit.
Regarding specs, my Mazda MX-5 could probably struggle to get up to 120 mph, but were I to get a Corvette, I could get maybe 200 mph? Wouldn’t be of any use to me though, as all I need is much less.
What I ought to do I guess is take the same photo with my Leica M10, and my Nikon D750, and see if there is any noticeable difference between them. Lenses will be the Nikon 50mm f/2, and the Voigtlander 50mm f/2.
Remember, I’m not making large prints, just full-size jpg images that anyone can view.
I rarely know what I’ll be shooting ahead of time. Sometimes, yes, but most of the time things just “happen”.
For me, it’s usually “which camera is good enough, and most convenient for where I’m going”.
It’s also true for me that I should pick one camera and stick with it, as otherwise my mind gets all confusabobbled about which settings to use, and how.
Also, to me, photography is about much more than the technical specs. The best photographers in years past hand ‘antique equipment’, no electronics, an everything came down to the photographer’s capability, not the camera’s. To me that’s as true today as it was back then. Anyone can take a technically perfect image nowadays, just letting the camera’s computer do all the work, but it will still be a “snapshot”. Joanna’s photos are stunningly beautiful NOT because of the technical stuff, but because of Joanna.
(If I were to buy a Z9 tomorrow, I doubt my photos would be much different from what I can do today.)
