Was the upgrade worth it?
Was the upgrade from the D610 to the D850 really worth it though? After all, I just said that I'm only looking for a camera to do one thing and that's take pictures. If the D610 took pictures well, did I really need to upgrade?
So to see if it was worth the upgrade I wanted to check the image quality of both cameras to really see for myself if the D850 hype was justified.
Beyond the marketing rat-race that is the megapixel war of 'more is better', I want to look at the actual results of the photos this D850 can take and as such I wont be focusing on all the fancy bells and whistles like touch screens and D-lighting improvements. I really want to get down to the core of photography here and that to me means image 'quality'.
Granted quality is a very personal and subjective topic and it's also something that is all to often unjustly associated with megapixels. The size of the file produced by the 24 megapixel D610 is 6016 x 4016px. This is clearly dwarfed by the monstrous D850's 46 megapixels and 8256 x 5504px file but is that really the deciding factor of quaintly?
Don't get wrong, megapixels plays a role in quality but just like buying a car with a top speed of 202mph and using it on roads limited to 80mph, it's nice to have but rarely ever actually used or more importantly needed. 99% of photographers will never need a file larger than 8 megapixels due to most of our work never ever leaving our screens. I use to use an old crop-frame, 8 megapixel camera for years commercially and those files were cropped into by art directors and blown up to billboard sizes without anybody noticing or complaining. Mega pixels are nice but ultimately rarely required.
So if I'm not looking at image quality from a megapixel perspective, how will I be judging 'quality' between these two cameras. I'll be looking at colour depth, tone separation, noise, latitude and anything at all that may influence the visual look and feel of a shot in my field of work, which is primarily artificially lit fashion and portraiture. If any of those factors are interesting to you as a digital photographer (that's a trick question by the way, they're fundamentally crucial to you) then let's get on with the test.
For my test I had to put stats aside and simply test it for myself and the following images and opinions are the results of those image tests. I've include all the images in a larger size on separate page too so you can make your own opinions too. They can be found here if you want to take a look.
If you're interested in the finer details of the D850 I highly recommend checking out these resources as they really know more than I'll ever want to know about the more technical aspects of the camera.
