Does Nikon AF-S TC-14E III have DX format? I found this information on dpreview.com

DX crop on a FF sensor is 1.5x or in other words, the resultant image is 1.5x larger. So, if you have a 100mm lens, the DX crop will "appear" to be 1.5x larger or "equivalent" to a 150mm focal length lens on a FF sensor.Does Nikon AF-S TC-14E III have DX format?

Yes, I should have added that a DX crop reduces the effective pixels of a FF sensor by 1.5*1.5 = 2.25x. So, a 45Mp FF sensor effectively becomes approx. a 20Mp resultant image; ie 45/2.25 = 20Mp. A 1.4x TC projects a 1.4x larger image on the sensor meaning you keep the same effective MP of the FF sensor.As I understand the difference, a TC projects a magnified image on to the sensor plane using the full area of pixels: eg 45mp in the case of Z9 or D850.
In contrast to optical magnification, DX format is a crop of the FX image projected by the lens on the sensor plane, as does a 1:1 or other crop ratio available on modern ILCs. So a DX crop records ~20mp image in the case of Z9 or D850.
The 1.4x TCIII is just an updated version of the 1.4x TCII, both for FX or DX cameras.Sorry, I didn't post a screenshot from dpreview.pl. What I found there surprised me and that's why I asked about the format for version III.
Any TC that supports FX mode also supports DX mode. There's just a typo on that web page where both TCs should show: FX (DX) as both work fine for both the full frame image and in-camera crops of that full frame image.Sorry, I didn't post a screenshot from dpreview.pl.
