Default FPS or megapixel?

I'm looking at the mirrorless offerings, and there are 2 i'm looking at, the Z6II and the Z7
the big differences are the fps and the image size.



all other stats on the cameras are the same or not worth mentioning (20 shutters per battery difference)

I'm suprised the Z7 doen't have the same or higher high end ISO, but even during astrophotography, iso doesn't go that high. I think the highest i have shot was 6400.
the dual processors in the Z6II and the much larger buffer are the reasons the FPS is much higher. I know the blanket answer will be 24MP is more than enough, but in astro, the ability to crop the image to bring up a DSO could be valuable

Depends on what your subject is? For stills and anything not moving or not moving very much it wont matter. For sports, birds in flight or motorsport it will. Ideally you want both. Are you married to nikon? In other words do you have mirrorless lenses for nikon already because if not you can do better with either canon or sony. Nikon is still in “catch up” phase with mirrorless but if you are looking at wildlife the nikon 600 pf lens is pretty awesome. You have to be a bit carefull though because some cameras will do high frame rates usually in electronic shutter but because they don’t have stacked sensor you will get banding at those fast moving subjects. So you would effectively be running at whatever the mechanical shutter can do. The canon r 5 does 12 fps mechanical and has 45 mp. The sony a7iv is 10 fos and 33 mp if i remember but that isn’t terribly bad since it has fantastic autofocus and tracking.

iso on new mirrorless cameras is a moot point. They handle noise well and software cleans it up the rest of the way.

yes i'm married to Nikon. I have several K in glass, and the FTZ adapter is a hell of a lot cheaper than replacing what i got

Then we are back to what do you shoot the most? Also the z7ii has better specs than both of those. And the z8 gives you fps, megapixels and stacked sensor.

this purchase will likely be for a while so buy once cry once

Good synopsis and I agree with the majority of what you wrote. You may have been talking specifically about Nikon, I am not sure but you wrote in more of a global way. Canon R5ii has a dual stacked sensor and can shoot electronic shutter up to 30fps. (which is honestly overkill for most any situation but that is a different conversation). When you reference banding that is caused by rolling shutter as when using "electronic shutter" it reads the frame line by line/ row by row instead of all at once with a traditional shutter. The "banding" really only occurs when using artificial light source that (flickers) like florescent or some LED or when using HSS mode on external flash. Again I cannot speak for Nikon, but higher end cameras (for the most part) have rolling shutter under control when using natural light. High ISO noise is definitely something to still consider on mirrorless bodies, but it also depends on how high you need to go and what type of work you do.

To the OP, as mentioned previously by Drew it really comes down primarily on what you shoot. There are no "perfect" cameras as they are just tools for a job and pending on the job you make your choice. Then after the job what are you going to do with the image...are you doing large prints and/or very heavy crops where max resolution is important...or shooting at night where the very cleanest native ISO is king...or are you shooting BIF where AF Tracking is critical...or combination like sports at night under low light where everything is kinda critical etc...

No right or wrong answers, just tools.

exactly. Yes i mixed up terms with banding and rolling shutter! Oops. It really comes down to specific use case. Also as you guys all know, I shoot a lot of birds in flight and 99% of the time I don’t shoot more than 15 frames per second. 30 frames per second is overkill for almost everything. I do turn it up though when I’m trying to get a very fast moving subject doing something I specifically wanna grab. Like an osprey when it jumps in the water to catch a fish or small very fast moving birds. But that is not often.

I shoot both. BIF as my recent stuff shows, adn I do astro.. nothing recently but I'd like to get back into it. I'm leaning to the 7, a bit cheaper, and the megapixels I will want once i get back into the dark places. my D780 is running 12 FPS

just curious, didn’t you recently get the d780? What is driving your push to mirrorless?

A camera is a tool. Buy the tool that matches the job. There is no "one fits all" occasions option. Sometimes you have to have multiple tools in your inventory. While I have a good deal of equipment in my "toolbox," I sometimes find I need something I don't have. In those instances, I rent from Lensrentals.com. There are other choices.
