Then why do they say that a 50mm on a <1.6>crop sensor is like an 80mm on a full frame?
Seems like more "perceived" reach to me.


Percieved, not actual.

When you put a lens on a crop sensor nothing, optically, changes. The angle-of-view is different. Best of luck.


I think that's what I said.

That's OK, perceived works - as long as you do not loose pixels......and your DOF and bokeh is OK.

I have and use my Nikon 200-500 without a teleconverter. Reason you can expect some image quality degradation.


Unless you are shooting to make monstrous enlargements to be viewed st arms length, I wouldn’t even consider it.

The D850 will make a 40X30 print easily, cropping from that will almost certainly give you a superior result compared to a 1.4.

There is not much of a difference, TC's work just as good with zooms than they do with primes!


No, they don’t.

When you look through a 10X pair of binoculars, your eyes don’t optically change either. And?

Print a 5x7 from a full frame and print a 5x7 from an APS-C (same picture in viewfinder) with the same lens.
Now tell me it's not an effective zoom.

I use the 200-500 with the 1.4 TC frequently for birds on a D500 or D850 and have been very satisfied with the results. I previously had a Tamron 150-600 but switched to this combo for even more reach and excellent performance. No regrets!

That argument goes on constantly here and its the equivalent of saying that just because I get somewhere faster driving 70 than 50, I'm still driving the same car.

Sorry, I cant follow that analogy.
Wouldn't we be talking about two different cars?

Rent one and see if you like it. When shooting wildlife, you never have enough reach. I have a 1.4x and have used it on a 150-600mm f5-6.3 on both a D850 and D500. It works fairly well on bright days unless you are shooting into deep shadows. It is hit and miss on cloudy days, when you might have to resort to manual focus. In any case, you will probably be dropping the shutter speed to 1/1000 or even 1/800 meaning using the tripod a bit more or holding the shutter button down longer as taking more shots compensates for the lower keep rate. BTW, the D850 and D500 have 15 of 153 focus points that support f8.

If I am purchasing a new AF-S Nikkor 200-500 lens to go with my D850 do I need to also purchase a teleconverter? I've been trying to read some information online but I am confused if it is something I really need? I will be using it both for animals and landscape. Thank you.


I wouldn't. The loss in image quality may be too significant to make it worthwhile.

Take a look at this review, which looks at it with the 1.4 TC

https://photographylife.com/reviews/nikon-200-500mm-f5-6e-vr/4

And the section posted below is one of the reasons why I chose the Sigma Sport over the 200-500. I found pretty much the same results between the Sigma Sport and the Nikkor. If it is your intention to use a 1.4 TC, you should rethink your plan to purchase a 200-500. The Sport is so much sharper, without the TC. With the resolution of the Sport, you could easily surpass the detail capture of the 500+1.4 (700mm) by simply cropping the image from the 600 and autofocus will be faster and more reliable with the Sport than with the Nikkor and the 1.4X.

There is no rationale that would convince me to buy a 200-500 after looking at this. The only other lens worth looking at would be the Tamron G2 - which is comparably as sharp as the Sport, and provides similar build quality and dust/moisture sealing.

The D850 in DX mode puts about the same number of pixels on the subject as a D500 with the 'field of view' of a 750mm. That should be enough for just about any situation.

You're better off leaving it in FX and cropping it. You have more flexibility in cropping.

Just a reminder:
You DON'T get any more "Focal Length" on a Crop
Sensor camera, just a reduced angle-of-view........

IIRC, a D850 has a full frame sensor
