This aperture series from f/5.6 to f/9 evaluates overall performance of the Fujifilm GF 35-70mm f/4.5-5.6 WR at 70mm on a distant scene.
In particular, it shows how judicious focus placement and ~zero distortion can product a stunningly good image that exploits the 100MP sensor really well.
Includes images up to full camera resolution plus crops.
You really have to see this image on a 6K display to appreciate the stunning level of detail—wow! But my budget is tight right now and I have to send the Dell 6K back in a few days and boy am I going to miss it.
