I've been using a Nikon D7000 (Dx format) for about 8 years and have accumulated several expensive lenses. I'm ready for a new camera and am interested in possibly one in the Fx format. I understand I can still use my Dx lenses but the Fx camera will automatically crop the frame to the Dx format. If I never buy any more lenses then it would be a stupid move, buying an Fx format camera and using it in a Dx format. At this time I don't know what other lenses, if any, I will want to buy (I'm 74 years young). If I buy more lenses I would buy Fx format of course. I would appreciate some advice, especially from anyone who has made a similar jump (from Dx to Fx). Thank you in advance.

I never made the jump so I would not know. My first digital camera is FX. I think if you want to go FX you should consider the cost of buying entirely new set of lenses for the FX. It may be too costly. Your DX lenses while usable on a new FX they don't deliver anything better on an FX body than on a DX body.

The thing about using a crop-sensor lens (DX) on a full-frame (FX) body, assuming you can physically do it, is you will get vignetting of the image. Maybe not all lenses, but the possibility is there. A DX lens is not intended to cover a full-frame sensor.
That's why you may not want to use some of your current lenses on an FX body.

The way I understand it, and according to Nikon, the Dx lens will fit the Fx body (does or does not require an adapter?), but, yes, you will get vignetting. That's why in the menu you switch to "auto crop". It will crop the Fx image to make it same as Dx but cut out the vignetting.

Okay, so it won't vignette, but you lose image. So why not just stick with all-DX lenses and bodies?

I dont know if this fact or not; in my experience of moving from Nikon D5500 DX to Nikon D750 FX no problems at all with any DX lenses in DX mode that I have used, the camera makes the changes automatically. I did purchase some FX lenses prior to the FX camera knowing that switchover would be coming some day. The FX difference to me was how much better my photos were in low lite situations photographing wildlife.

Actually when a DX lens is used on an FX camera you get less than half, my D750 in FX mode is 6000x4000 (24mp), but in DX mode it's 3936x2624 (~10mp). I discovered this when I tested my DX 10-20mm lens (for my D5600), switched back to my 24-120 FX, and didn't notice the camera did NOT return to FX mode automatically. Lesson learned. Greg.

I went fron a D70 to a D810 and all the extra you get unbeatable and with the a lens added once in awhile will fire up the inner passion you have for photography I got mine online at nikon.com and it was refurbished and about twice a year they have a special which includes shipping

Correct! You wind up with less resolution than on a DX body.

Unless you need the advantage of an FX body, (greater low light sensitivity, less noise at higher ISO), I would go with a high end DX body! That way you get the advantage of full use of your DX lenses.

Many DX users make the move from DX to FX.
Not so many FX users move from FX to DX.

You didn't mention what your favorite photography subjects are or why you are thinking about a FF body. Why eat the expense of a full frame if you don't need more pixels or better low light performance? Then there is the cost of new glass. If you do need a FF body, look at the D750 (24mp) or a D810 (36mp), both of which have been severely discounted lately, especially if you buy used. If you have money to burn the D850 (45mp) is arguably one of the best FX dslrs ever made. If you are going to stay with DX format look at the D7200 (24mp), D7500 (20.1mp), or D500 (20.1mp). Again, there are some great deals out there for used DX bodies, especially for the D7200 (around $500). I picked up a pristine used D500 with a power grip for a great price. The D500 is arguably one of the best DX dslrs ever made. For FF lenses, look at the trinity of the Nikon 12-24mm f2.8, 24-70mm f2.8, 70-200mm f2.8 and add a 1.4x teleconverter. That will cover most anything you want to shoot unless you are really into wildlife and birding, then you'll want to reach out to at least 500mm and the Nikon 200-500mm f5.6 is a good choice. Each of these lenses will set you back from $1200 to $3000, but can be had for 20% to 30% less if bought used.

Thanks, Srodav. A lot of good info from you and others has been shared with me and I appreciate it. I like shooting landscapes most of all and I think I have decided to stick with the Dx, like a D7500, and use the lenses I have now. If I was going to buy a new camera AND new lenses I think I would go mirrorless.

Strodav Loc: Houston, Tx

Good decision and I like your plan. I'll seriously look at mirrorless in about a year from now.

SteveR Loc: Michigan

Probably a good decision. To really take advantage of a full frame camera like the D810 would require some very good full frame lenses that are not inexpensive. Unless you're into the hobby very heavily like an avid bass fisherman.....you could consider it comparable to the cost of a bass boat.
