I use mine with the holy trinity and an 85 1.4. I'll have to do some tests with some of my older, legacy glass to see what that's like. No complaints so far however. I had intended to use it only for portrait work, but the XQD card is so damn fast that I'm actually using it for a lot of event work and other stuff (and chewing through digital storage at a phenomenal rate..).
Not worried about the glass. Worried about the processor and HDD. Lightroom is already the world's worst application for handling large files -- I had to upgrade my rig when I went from 24 to 36MP in both the processor and storage space.
I'm happy with m 12.1 mp D3s. I might feel different if I were a professional studio photographer, but I just shoot for fun, and mostly film, so the latest and greatest digital camera isn't a priority for me. Most of the issue I have with more mp is the file size. I already hate dealing with digital editing anyway, I can't imagine the suffering that 45mp would cause. I sometimes shoot for work and the camera there is a measely Fujifilm Xt-2 with 24mp, and that already feels more sluggish when editing. Also, having to buy all that extra storage space isn't appealing to me at all. Obviously, we're all different, but that's my 2ยข
I cant use my d800. My computer is to old. It takes me 5 minutes to load a file from just the 7100. The hard disk lights up red on the screen with out of space, out of memory issues. I have external drive too but havent put enough on it, because the computer is so short on memory and space it takes forever to transfer anything. I did delete enough photos that it almost made it through a defragment session. I think it is like 8 years old? Only 4 or 6 megabytes of ram. Nikon software just freezes sometimes while i edit. Then i have to unplug it and take the battery out and restart it. All really quite amusing. I have sd cards of photos i just hang onto, afraid to try to process them. I probably should have put more photos on the external drive BEFORE it was to this point. It just freezes somtimes now. Poor thing is confused and overloaded. I edit a lot on my phone now
I hope this is not a dumb question, but what do you mean by the "holy trinity". I'm sure you don't mean onions, celery and bell peppers and I doubt it is a religious reference.
If you really want MPs resolution, stick with film (especially medium format and above; especially fine grained low speed film).
With digital you may/have to upgrade your computer (processor, RAM and disk space) as you upgrade your camera. That is the hidden cost of upgrading the camera.
