Seapy- How is the D800 working out for you? Are you satisfied with it, or do you think the D810 might have been a better choice? I ask because I'm thinking of buying one or the other. I wanted a D850, but the prices are just getting too attractive for the 800/810, $800+/- for a excellent used D800 and $1400+/- for a used D810 in excellent condition. I'm also wondering if the extra $600 for the D810 will get me that much extra performance? I'd be using the camera primarily for studio work and portraits/landscape, probably not for astrophotography. Your thoughts and those of the other members would be appreciated.
I am absolutely delighted with the D800, the colour depth, the recoverable shadow detail and even the recoverable highlight detail are far better than I have experienced with the D3 or even dreamt possible. The time lapse feature is very useful because it produces a simple video file instead of thousands of JPEG's which then need processing into a movie. I would have preferred X2 CF slots like the D3, I don't like the SD cards at all, way too picky and fiddly but that's life I guess.
The downsides are, I don't need the resolution, except perhaps for astro photography where it allows greater detail to be recorded. The large file sizes and the increase in astro intervalometer stacks has caused me to have to fit a larger SSD for this current years images, up from a 250Gb, to a 500Gb, which is well over half full already... I am expecting to need a 1Tb drive next year. And I haven't taken a picture with the D800 since mid may in Scotland, I have been so busy with summer projects I haven't had time for photography. I feel the high resolution is inevitable and unavoidable if I am to enjoy the benefits of the better colour depth and greater dynamic range.
Yes, I do plan to get a D810, I believe the IQ is slightly better and there are other items in the specification list which would be good for me. Longer exposure and more flexible intervalometer settings from memory. Although I have just obtained an MC36 remote which will allow me to use bulb on the camera and set longer exposures than I will ever need in practice. I think the image processor is newer on the D810, which probably speeds up the processing but more importantly results in even better images.
An unexpected and wonderful outcome from the D800 is by bracketing the exposure, I have been able to copy many Kodachrome slides from the 1960's which were very poorly exposed, we didn't possess a light meter in those days. Bracketing and using Lightroom HDR together with the 'auto' settings allows the recovery of many slides which were otherwise unusable.
I have seen excellent, very low shutter count D810's for less than you mention. I went with the D800 because it was bargain, I still intend to get a D810, I can't afford nor do I see the need to go the extra mile for the D850.
I am expecting to use the D800 on a bench setup and the D810 for outdoors and astro. I like to do long term time lapse and intend to start image stacking, so it means disturbing the setup when I need the camera outside.
