The caveats you listed are valid ones. I personally don't use or like Live View for anything unless my camera is on a tripod. It's tiring to hold the camera out in front of you, and I've had problems with the screen in bright light. Having said that, the Live View mode of the D780 does use phaes detect autofocus, so it is not crippled like every other Nikon DSLR, including the D850.

A more sensible upgrade would be a mirrorless camera, but there may be a need to buy new lenses along with an F to Z adaptor, depending on what the OP has. (Any with the screw drive, no autofocus.). The cost would be greater.

Sorry for my statements were not clear enough. I meant if I shoot photo with my D610 at f2.8, s1/80, ISO 1000, then with a D780 I can do f3.5, s1/160, ISO3200 in order to yield about the same quality and noise. That's what I meant D780 would allow me to shoot at a faster speed, wouldn't it?

I had only a faster prime 50mm lens(1.4) and a 24mm(2.8), all others are 4.5 and above. How do you justify buying fasters lenses or a faster camera(higher ISO)

No, if the image was under-exposed at ISO-1000 on the D610, it probably won't look any better (and still underexposed & noisy) at ISO-3200 on the D780. Although you'll get better higher ISO performance with a newer sensor and processor, you'd likely be better served looking at (a) wider-aperture lenses, or (b) VR support, or (c) IBIS support.

Now I got confused. Isn't a faster camera (higher ISO) would yield less noise. For instance for normal exposure, at ISO 1000 for my D610 would yield the same amount of noise at higher ISO for D780?
Isn't that an advantage for buying latest camera with higher allowable ISO?

CHG_CANON Loc: the Windy City

Noise performance is not linear, not across ISO values for one specific camera model, nor across ISO values from different models.

Higher available ISO maybe worthless, or very usable. It depends on the camera, the exposure situation, and the photographer's needs. There are no applicable and reliable generalizations.

Again, seeing an actual result from the D610 would be the appropriate basis for discussion of the current issues and the relevant causes and possible corrective actions. It would be sad, but not unusual, to throw $1300 into another camera to achieve no tangible difference.

Thank you, I was mistaken that a later camera with higher useable ISO would allow me to shoot at faster speed with my so so lenses. Now I have to think trice, and besides the stock market dropped today that I lost more than the used D780

"Not see a difference" refers to image quality. Theres some small IQ edge to my 750 over my 610. "Small" means if you dont carefully look for some quality difference youll never notice any.

I dont put the two cameras into a controlled "A-B" comparision, but the 750 does seem to focus with very few small errors and the 610 seems a bit more error prone.

I routinely use very high ISO so noise is just normal to me. When youve got plenty of noise its not esspecially noticeable if one camera has just a bit more of it than another.

I *SHOULD* say something like "I pity fussy users who endlessly test image quality". I *should* say that but I dont cuz it makes me laff so hard that coffee shoots outa my nose ... okay, slight exageration.

A "better" camera is all about better enabling the user. The IQ difference, if any, is NOT what makes better pix, its the "unshackling" of the user. Im all for better cameras. *I* can feel the user benefits. But if your 610 doesnt make *you* feel shackled then keep it. A 750 wont noticeably up your IQ and altho Ive never touched a 780 I have never read that its a real jump up imagewise from a 750.

If you want a more enabling camera, SLR deveopment has ended. The 610 is a "fairly recent" midlevel SLR. Youll hafta go beyond SLRs to find a truly more enabling camera ... and the IQ upgrade still wont seem really impressive. But the upgrade WILL be there if you love running controlled tests.

FWIW I use 610, 750, Z6 and Z7. Acoarst the Zs now get nearly all the action, but I do have solid user experience with the two SLRs. Its just that Ive moved on. As I said, I do LIKE better cameras.

My answer might not apply to you. You need to sort out what makes the most sense for you.

tenny52 Loc: San Francisco

thank you, I will wait for it a little long. Isn't the later camera with a higher useable ISO has less noise with the same setting?
Meanwhile, I don't really need a better full frame without much breakthrough; I am concentrating on how to use my Insta360 efficiently.

I have no experience with the D780 but the 24-85 f3.5-4.5 AF-S, VR is a remarkable little zoom. It is sharp and although distortions are present at 24mm in my experience Nikon software takes care of that.
As I said, if your D610 is not satisfying your needs and you need a better AF then an upgrade is in order. I shoot mostly landscapes and for me AF or Manual Focus make no difference.

If it isn't broke, why fix it? What is it about your current system that you have a problem with? Is your gear limiting you or would workshops, photography courses, or travel be a better investment than new gear. DSLR development has ended because mirrorless cameras provide significantly more advantages in focusing, shutter speed, information available prior to shutter release, and vibration at low shutter speeds--even an inexpensive, used, fixed lens mirrorless camera is a better investment if your current DSLR is limiting you. If your gear is limiting you, consider that going from one DSLR to another DSLR is an insignificant an advance in usefulness compared with going from a DSLR to a mirrorless camera. Good luck with your decision.

Well said.

The short answer is maybe.

But the question makes me wonder if you really understood UIDs detailed reply.
