Being fairly new to digital photography, I'm still learning...a lot. Here's my question. I currently use an older Nikon d700 for the bulk of my still photos. I think it is a 12 megapixel. In practical use, is there enough difference in image quality to warrant the move up to something with over 20 megapixels? I do make some prints up to 30x40...and I think the results are quite good. I love the d700. It's as solid as a rock....but am I missing out? I'm only interested in image quality.
You have received a lot of thoughtful responses, both for keeping and for replacing. In the end it is up to you, and in my opinion it at least partially depends on your personal needs and objectives.
First, since you like to print large, you undoubtedly will appreciate more pixels if you acquire a camera with a lot more of them than your D700.
Second, you need to consider the purpose behind your photography. Is it for your enjoyment and perhaps those with whom you share? Do you sell at least some of your work and work to increase skills needed to achieve the level of a pro? [Excuse me if you are already near or at that level!]
Third, in my opinion, there is a balance to be sought in photography. As an attempt to explain, I will first tell you about my journey. I started digital photography with a point-and-shoot, after a number of years without a camera [film]. Loved it, got some great photos, learned a lot about composition and a bit about editing. That lasted several years. Then I began to want more control over how the images turned out, so after doing some research, asking questions, and holding the candidates in my hands, decided on my first DSLR, the Nikon D7000. At that time [2012] it was the top model of crop-sensor cameras and the best I could afford. With it I purchased two "kit" lenses to cover most of the most common focal lengths. This kept me happy for another few years.
As I learned more about so many aspects of photography and improved my skills, it became clear I would eventually want to upgrade to an FX camera. Quality and detail of images were important to me. I began to make purchases of peripherals as I began to see the need for them - better tripod, filters, and FX lenses. After all that I bought a D810 when it was on sale in the fall - Black Friday/Cyber Monday! Of course the D850 came out after that, but I had enough camera to satisfy me and was not about to succumb to "GAS"" And, once again, it was the best I could afford!
So back to balance. What you need and what you can spend are two things to balance. Some can go for it all at the same time, others like myself have to take a more gradual approach. Evaluate what you have and what new gear would best suit your photographic objectives.
The camera and lenses are inter-related because each one functions in relationship to the other's capabilities. If you already have good FX lenses, that is a good start. However, they can only perform as well as the camera's capabilities will let them. Better lenses do improve a camera's performance as much as they are allowed. So owning better lenses and wanting to improve quality of images does suggest that a better camera will increase the performance of those lenses. On the other hand, if the lenses are not high quality, they will not improve significantly on a better camera because this time it is the lenses holding the camera back from its full potential!
As technology advances, the camera manufacturers have taken advantage of that to make changes to how the cameras are made and perform. Sometimes photographers do not like some aspect of a new camera, and the manufacturer may revise their design eventually. But in general, the advances have been improvements. Thinking of it that way, you have a good camera, but Nikon lists it as "archived" because it has been succeeded by models that do what it can do but better, and that also can do more.
So in your situation, it is a matter of whether new lenses or a new camera will be the best investment to achieve your objectives. It is often said that it is the photographer behind the camera that makes the most difference. That is true, but on the other hand an artist seeks the best tools to accomplish the fulfillment of the vision. Sometimes the tools at hand are good enough, but other times the artist decides a new tool would allow better workflow and better results.
Hope this helps!
