Mr. Burkholder brings up several interesting arguments in his first post above. I have not considered them before and will certainly have to investigate them further.

One thing that I know from experience is that Nikon makes only a small handful of premium, professional grade lenses specifically for their DX cameras. I have owned a 17-55mm f2.8 DX zoom for probably 12 years. It is an outstanding lens and still delivers the highest level of performance when used on my D500. I also have occasionally used it to shoot square format on my D810 and D850, where it yields results fully comparable to the 24-70mm f2.8, except for image size. I have also looked at the Gold Ring 16-80mm f2.8-f4 DX zoom, but found it pretty disappointing. It turns out to be f4 over almost all of its range, and its construction really does not impress me.

On the other hand, I extensively use an FX Gold Ring 24-120mm f4 zoom on my second D500. That lens needs a little boost on saturation, contrast, and sharpness, but otherwise delivers consistently excellent results on the DX body.

My biggest concern with using an FX lens on a DX body is really around what might happen with stray rays of light from the larger image. In teality, I've never found this to be a problem in the 12 years that I've been using DX lenses. It could become a problem if the flat black paint started flaking off of the structures inside the mirror box.

To summarize, I have experienced zero downside from using full frame lenses on DX cameras, going all the way back to my D200. I have paid a small weight penalty, but it was nothing insurmountable. And when I did expand to full frame, I was ready to go except for a better wide angle and eventually a longer telephoto.

Good morning fellow Hoggers!
I enjoy and appreciate much of the dialogue here as always.
After six years with a 5200, just recently, I stepped up to the D810. What an incredible difference as most of you well know. I was able to acquire a few FX lenses to use when I got it.
So my question:
The 5200 has one SD card slot of course, that was what I used all the time and I always kept the SD cards after they filled up because memory so cheap. I think I’m ready to start recycling those from several years ago. With good back up, there is no good reason to keep them.
The D810 has one CF card and one SD card. How do you folks manage the use of these two cards? There’s three options I believe, I forget right now but there’s three options as far as how to manage the saving of files. I shoot and save only RAW and then everything goes through Lightroom (on to PS for special work as desired). My workflow right now is everything comes off the SD card because I can plug that right into my computer to load to my external working drive.
So I’m only saving RAW.
How would you suggest using the CF card in conjunction with the SD card?
Thank you all!

I need some advice. I pulled the GAS trigger today on a Nikon FF camera to replace my D7500. I'm not a pro. I shoot landscape, still life, and things that don't talk back. I have a full assortment of crop sensor lens,

I shoot a Nikon D750. I have this lens and it rarely leaves the camera. Many others on here have, and love this lens as I do.
Thanks, Boone.

HI folks! I'm back as PP Forum co-moderator. There has been a lot of ugly behavior here this week, but I've locked the most contentious topics and now we're going to move on. If you have a personal problem with another user, take your argument to private messaging or The Attic.

Please review the revised section guidelines here, including the paragraph about unacceptable behavior. I'm confident that everyone knows how to offer constructive feedback, advice or observations. I'm equally confident that responding to well-intended comments (even if negative) can be done graciously. If you don't have these skills, this section is not for you.

I've decided to go back to how most of UHH is set up regarding editing: no edits or alterations may be done without OP's permission. Some users give blanket permission (or refusal) in their signature line; some may prefer a case by case basis. If it's not clear, be sure to ask.

Constructive suggestions for section improvements are welcomed. Many thanks!
