I took both a D850 and a Z8 to Alaska last September; as far as IQ, in simply viewing the images I challenge anyone to tell me which camera was used to get the shot. For me, the proof is on paper so to speak. While the Z8 is the newer kid on the block, the D850 still delivers. Multiple images from both have been enlarged to 24 x 36 and greater with little to no apparent loss of detail. Both cameras used the same Nikkor F mount lenses, a 24-70 and a 70-200, f/2.8s; you do need very good glass for both bodies to shine. It is complete rubbish to think a DSLR is no longer capable of excellent images because it has a mirror! Yes, the Z8 may outshine the D850 when it comes to certain wildlife moments. I have several manual focus Nikkor glass from film days and do prefer that glass on the D850. What I like about those big NEF files, I can do some cropping and still get excellent results.

I don’t think anybody is saying the IQ is less with a DSLR, just that it doesn’t make sense to spend that kind of money on one now.

If I want to improve a Nikon D500 image (20.5 mb), can it be made comparable to that of a D850 (45.4 mb)?

If so, how? Is that equally so for JPEG and RAW formats?

What are the trade offs?

Many thanks! I feel the way I did in analyzing family finances to pay for three undergraduate degrees at state schools in NC. The goals were for all of us to be debt free when they graduated. The kids were 1, 4, and 8. I could define various goals, factors, and assumptions. But I was never confident in my ability to set up the equations accurately. FYI the Andrew Tobias Managing Your Money program had a fill-in-the-blank section that handled it well. The upshot was that I needed to make more money and I figured the potential of my day job exceeded that of any side enterprises.

I’m not quite sure what your needs are here. Yes there is software that can increase the resolution of an image. Within Lightroom Enhance can do it or something like Topaz Gigapixel. The question is why you would want to do it to a 20.5MP image. If you’re printing 20MP is plenty for pretty much any size print and for digital use, as has been stated, 8.3MP is all you need for 1:1 display on a 4K monitor. It’s just a little over 2MP for a regular FHD display. Those enlargement tools come into play when heavy cropping is required. Considering that the D500 is ASP-C and the D850 is FF, the 45MP of the D850 certainly allows for more cropping but the crop factor of the D500 potentially lessens the need for cropping. If you put the D850 in DX mode it’s the same shot you’d get with a D500 but at about 19MP, so pretty much the same.

Is another $2,500 the cost of making you happy with your camera? Will it make you a better photographer? Only you can decide...

(BTW - is that the entire cost? Do you need expensive FX lenses too? Do you need a better computer and / or larger storage for these larger 45MP files? Do you need pro-grade digital editing software along with that upscaled computer?)


Mine does 45 and i use Craw to get them smaller. I find the excess pixels more of a PITA rather then a positive. Yes space is cheap but taking 20 stacked pics and processing in PS or whatever, is not worth the CPU time even on a fast box. Next time I get to do a road side sign, I bump it to full raw.

If the OP actually has both cameras, the D500 and the D850, there's plenty of opportunity to compare and test the ideas of how to make the smaller MP sensor 'look' like the larger. My opinion is you can't upscale one image and get it to look 'comparable' to the other, that is acceptably comparable. But, the OP has the tools to make that comparison personally, assuming the software is available too.

Megapixel resolution is a size number used to calculate the amount of information gathered from a sensor. More photo-sites create a larger file size. That can be money in the bank if you enlarge for print, or want to crop.

You can improve your image sharpness or contrast with lenses, but size gained with an AI editing tool is a waste of data space and has nothing to do with image quality if you stay withing your original viewing limit of 20.1 megapixels. A typical computer monitor is only 5 megapixels in comparative size.

You will not see a difference between 20 and 45 megapixels until you surpass 21 or 30x40 inches, and that can be something most never do, yet advertising more megapixels seem to be a great for sales.

Megapixels do not exist. The term is a measurement calculation used to reference resolution size.

Mentioned it on page 2.

YES YES YES its not the megapixels' Its all about settings on how it was shot as in shutter speed aperture settings etc. d500 is a good camera. Try just changing some settings. If your looking for sharper images shoot at a higher shutter speed.

Wow. What an astute non observation.

Nobody cares.

Nobody ever said there should be a difference. Beats me why you or anyone else ever brings up that that nothingburger.

Anyone with common sense knows that the viewing and focusing system is one thing and the image recording system is another.

No one ever said that the SLR viewing system was going to improve IQ over rangefinders, which were displaced by SLRs cuz it was the superior viewing and focusing system.

Better viewing and focusing always displaces earlier, less capable, systems. Que sera sera.

A D500 is a APS-C (half frame) size sensor.
A D850 is a full frame sensor.
Since the full frame specs are a little bigger than twice the size of the C format, you already have a practical match. If you watch a bigger print, get a bigger camera (format).
or wait a few more years until AI does everything.

And you don't need a camera or travel.

I quite often up-size small crops out of images (from both from low and high resolution cameras). Topaz GigaPixel AI does a great job. Just makes the images easier to visualize.

A master carpenter once told me: "no matter how many times and ways you cut a board, you can't make it larger".

The application to digital images should be obvious.

Upscaling photos and video is not a new concept. Information is added to the original in some intelligent way. The results can be quite good. I have a large number of DVDs. With upscaling, they play with near HD quality, not quite, but an improvement over the original.
