Full Frame vs Crop Example
Oct 27, 2019 10:19:33 #
We can argue the question and disagree all day but we can't settle the issue until we actually do a direct comparison.
In the next post I will display two images taken with a Nikon Df (full frame) with a Tamron SP 35mm f/1.8 and a Fuji X100T (APS-C) with its fixed 23mm (35mm equivalent) f/2 lens. Both were taken at ISO 200 1/1000 @ f.8.
The two JPEG SOOC images had slightly different brightness levels (the clouds were moving) so I brought the two raw files into Capture One and used "Auto Adjust all Selected Variants" to get them as close as possible. This applied slightly different Exposure, Highlight and Level adjustments but did nothing to Clarity or Structure.
I wanted to see if there was a difference in resolution or other quality. There should be a tiny difference in DOF because the hyperfocal distance for the Fuji is about a meter closer to the camera.

Here are the two images after development in Capture One. Please download them both and compare them at the same magnification to see if you can tell them apart. So far I can see a slight difference in the chromatic aberration (along the white fences) for the smaller lens but not much else of significance. I would expect that both images could be printed at 12x18 inches and you might not be able to tell them apart.

I downloaded and blew up the images. Frankly, I couldn't really see a difference. Perhaps it is my monitor.

Very good examples, Scotty, I have both Nikon DX and FX cameras and can't tell the difference.

I had to blow them up to 100% on my calibrated 4k monitor just to find the chromatic aberration.

This should put an end to the argument for those of us who don't print larger than 24" Thank you for these examples.

Now to finish the comparison, take a shot with each in low light at ISO 12,800 and post those please.

Nearly all men can stand adversity, but if you want to test a man's character, give him a crop-sensor camera.

Is either camera doing an auto lens correction in camera ?? What is the difference -if any- in pixel density ?? A difference in pixel density will be the largest contributor to any perceived IQ differences IMO. As mentioned ISO 200 is not a complete test ! ISO 1600 would be nicer. 24 inch prints would be nicer too. It would also be nice to have a subject with all-over details and multi-colored 8-)

Not like some people have their opinions cast in concrete.
Or others that keep wanting to make things more complicated?

The test was only for image quality, not noise or anything else.
The Fuji base ISO is 200 and after reaches ISO 1600 it stops using analog gain from ISO 2000 to its maximum ISO 6400.
There is also a big difference in size:
and the X100T was a lot less expensive. The Df with theTamron attached weighs almost 3x as much.
