Magnification (reach) is determined by dividing the horizontal width of the sensor by that of the angle of view of the lens at the zoom of its setting.
If the 1.3 setting is reducing the horizontal width of the angle of view (which I believe it does) then there will be a bit more magnification (reach).
Steve, Great Article.
Thanks for preparing.

Yes, in camera or software the crop is seeing the same pixels.
You could prove it to yourself by simply taking 2 shots.

Bill, do you really expect people to take the time to do the experiment when they can type a few words on UHH and waste everone's time.
Most people are just too lazy to do the work themselves.

I am beginning to shoot primarily wildlife with a crop frame Nikon d500 and a 400mm f/2.8 lens. In the camera shooting settings I can choose DX mode (5568 x 3712) or 1.3 crop (4272 x 2848). I believe that if I use the 1.3 crop selection, all the camera does is crop away the perimeter of the larger image leaving me with a smaller 4272 x 2848 sized image. Is this true ?? If I cropped the image to 4272 x 2848 in post processing do I have the same quality as if I cropped it by designating 1.3 crop in camera ?? What's the difference if any ?
A quote from a non Nikon after market manual on the d500 says "Sports and Wildlife photographers often find this option which produces 12.2 MP image a very useful to give their images EXTRA reach". Of course i want the best image quality, but at which "Image area" setting ??

One thing to remember GC if your interested in quality the more you crop and sharpen the more noise the image has. I have the 500 I use for sports for the extra reach. Use the camera in regular mode as it was intended. Just my opinion.
Good luck.

Yes, I have both my d7100 and my d500 set up for back button focus. Once you have used it for a while it becomes second nature. I don't even think about focusing anymore. It is a must for any bird photography.
The only time it becomes a problem is when you hand your camera to someone and ask them to get a shot of you...............
Whenever I'm in that situation I just pre-focus with my back button and tell him/her where to stand and to just press the button.
Let me first admit, i love the musings of Mr Perry, i have learnt so much from his two books and postings. But like all advise, use it as it best suits you. Steve says frequently, he is sharing what he finds most useful, and he is mostly right on, but use what suites you best. I shoot a D810 and do quite a bit of cropping, leveling, re framing after i get home and look at the shots. If you crop in Camera, while there is the obvious space on your card and buffer improvements, you miss "Some", for me, important benefits of post cropping as necessary.
Take the shot as the camera intended full sensor, then you have options.
I still love your work Steve......

I am heading out at daybreak in the morning to shoot some River Otters as they come up onto the ice with small fish. I'll see how DX mode (5568 x 3712) works out. Look for pics......

Don't bother with the in-camera crop.
You get EXACTLY the same results if you simply crop the image later in post-processing, at your computer.

Exactly. The only reason to consider is that you might squeeze an extra shot or two into your buffer if buffering is a problem when you're shooting at high speed continuous (or the Canonquivalent).

Good article.
Your D850 might have one additional crop mode. My D800 did. If I took a still photo using live view the image was cropped to a 16:9 aspect ratio. I liked that for landscapes because I end up using it anyway.
Alas my new Z6 has crippled user selected image areas if you attach a DX lens. Which is too bad as some of my DX lenses worked OK, at least over a limited zoom range, all the way up to FX.

I don't expect anybody to do anything. It was just a suggestion in case there were conflicting answers.

Sorry to waste your time....But it was your choice to take the time to post your sarcastic childish answer. It is just these types of posts that keep "less experienced" readers from posting their questions.
The weather did break today and on a rare day off I did get out to set up and compare the two "Image Area" selections. The majority of posters who said that the two are identical were absolutely correct and I thank them for their guidance and wisdom. For those who took the time to lead me in the right direction...Thank You !!

The little buggers didn't co-operate this morning, but I did get to set up and compare the two "image Area" selections and they are identical in image quality when viewed at the same size side by side.
