200-500 + 1.4TC on FX vs D500 naked
Just wondering which would be better? Since the 200-500 is already slow, would losing another stop negate the noise advantage that FX has over DX? I would prefer to use my D750, merely a lot of times, it doesn't have enough reach. I frequently take to crop, which once again, probably negates the FX reward.

With regard to paradigm quality, there is little departure between an FX camera with a one.4x TC, and a DX photographic camera without TC using the aforementioned base lens and shutter speed, provided they're both similar-generation technology. It doesn't thing how "fast" or "tedious" the base lens is. The FX camera volition not take a significant "noise reward" unless you lot requite it a longer exposure fourth dimension - merely in many types of shooting, that isn't an option.

A TC cannot improve the optical quality of an paradigm - the near a TC tin can achieve is to not degrade the quality of the image produced past the lens it is paired with. But real world feel tells united states that, if at that place is some loss of prototype quality using a Nikon i.4X TC on a quality Nikon lens, that loss is likewise small to exist meaningful. For all practical purposes, the 200-500 solitary on a D500 or combined with a Nikon i.4X TC on a D750 are effectively equal (optically).
Nevertheless (maybe that should be capitalized), the loss of an f stop by using the TC is quite meaningful. The D500 has as proficient an autofocus capability as yous'll find in a DSLR, and using it with the 200-500 volition the best autofocus that lens can achieve. Mountain the 200-500 with a TC on a D750, and you have a lesser autofocus in the camera that's now forced to focus with a one stop less light.
My money would be on the D500 plus 200-500 getting shots near sunset that exit the D750+TC plus 200-500 hunting because of less light. Every setup has its low lite limits - you'll hit that limit sooner with the FX+TC option.

The main problems with adding a TC to the 200-500 are that, showtime of all, the increased focal length requires the servo loop to tedious downwards (even if there's plenty of light, since information technology has to do with loop gain and stability margin), and secondly, you end upward having only the reduced set of f/8-uniform AF points to work with.
Every bit a full general principle though, if yous are not catastrophe upwardly at a narrower discontinuity than the AF system is designed for, adding a TC does non reduce the light to the AF module. The image at the AF sensor chip from an f/iv lens for example, is no brighter than it is with the same f/4 lens plus a 1.4x TC. AF optics are not very intuitive.

Interestingly all AF points tin can be "selected" with the D500, TC14E III, and 200-500 at 200mm and unmarried point AF locks on.
Zoom out to 500mm and, although any AF bespeak tin be "selected", AF but locks on with the 37 selectable points shown on page 99 of the transmission for the TC800 i.25 for the 800 prime number.
Nikon does not specifically specify what the number of AF points available is with a TC14E III. I find it is "well-nigh" 37, with reduced AF ability for the far outer left and far outer right points mentioned for the 800 plus 1.25 converter.
Oftentimes all AF points working, (as distinct from existence selectable) volition give an AF advantage on the D500 with "blank" 200-500 compared to just 17 being selectable (presumably 9 as cross blazon) with a D5, TC14E Three and 200-500 at 500mm for a similar field of study coverage at the shooting stage.
Page 99 also mentions "(note that at maximum combined apertures slower than f5.six the photographic camera may not be able to focus on dark or low contrast subjects)".

Very true. All the same if, as I assume the OP might exist interested in wildlife and peradventure bird photography where yet more than reach is often needed, and so I would also bespeak out that he could likely soon consider using a D500 plus a 1.4 teleconverter on the 200-500 giving a 280-700mm zoom equivalent to upto 420-1050mm FOV. The D500 tin still apply xv focus points at F8 (9 selectable with v being cantankerous blazon) with this setup according to the D500 manual (page 100) which is however not at all bad.
And so my advice would porbably exist to go for the TC pick initially (equally information technology'southward the relatively affordable option) and then get the D500 afterwards.
As a general principle though, if you are not ending up at a narrower discontinuity than the AF system is designed for, adding a TC does not reduce the light to the AF module. The image at the AF sensor flake from an f/4 lens for case, is no brighter than it is with the same f/4 lens plus a 1.4x TC. AF eyes are not very intuitive.
I call up that'due south by and large right but that is assuming that all Nikon AF sensors are all merely at F5.six. Which may maybe be true for older Nikons. On the confront of it information technology looks like the D500 (and presumably also the D5 at least) have some AF sensors that are working at F4 - this is judging from the information on page 99 of the D500 handbook which shows that some of the AF sensors tin can only work with lenses that are F4 or faster. The only other explanation I can recall of for this is that perhaps Nikon might take deliberately "crippled" the AF sensor functionality in firmware perhaps to allow for farther future "upgrade" without too much effort.

Aye they Exercise specify - it'due south on page 100 of the D500 user'southward transmission. They say for a lens with max discontinuity of F5.6 (at max zoom) and with whatsoever 1.4 TC fitted (including the TC-14E 3) the D500 has 15 focus points (9 selectable with 5 cross sensors).
So that does not concord with what you are challenge.

I don't have experience with the D500, just I've put the one.4tc (E-Two) on a number of my lenses, including the 200-500, on a D810.
Yep, it becomes an F8 lens, and aye, you see a noticeable IQ comeback stopping down further to F9. This is a huge modify, but can ofttimes be fine in good light. I spent years shooting my old 80-400 AF-D at F9, so I know it tin can exist useful.
What's less obvious is what happens to autofocus speed, until you lot actually employ the philharmonic. I spent a couple of days trying to shoot hummingbirds in flight (at a feeder), and the AF speed was then slow (coupled with narrow DOF) that information technology was mostly an exercise in frustration.
Because the D500'due south reputation for AF, I'm pretty sure a 200-500 on that camera will be MUCH MUCH more useable in the field than the 200-500 + 1.4TC on a D750. Plus y'all get the reward of beingness able to shoot at F5.half-dozen instead of F8/F9.
If you have static subjects, I think there is a narrow range of subjects at distance where adding the ane.4tc makes sense over merely cropping (on FX). Myself, I'd rather get the shot and ingather for proper framing than miss the shot considering it wasn't in focus.

2d your contour shows a Tamron rather than the Nikon 200-500.
What I report applies to my 200-500, D500 and TC 14 E III - i.eastward. more than AF points are tin exist selected and are useable at 200mm zoom every bit distinct from just being displayed in the viewfinder; than at 500mm zoom, even though at 500mm all AF points are displayed in the viewfinder.

Re: 200-500 + 1.4TC on FX vs D500 naked
Information technology's a rather late respond but I struggled to find a good drove of unedited however and BIF photos from the 200-500+TC1.4E III combination when trying to make the decision.
For anyone wondering what an amateur can pull of with this combination take a look here. These are direct from the camera except for some RAW adjustments to exposure.
