This frog image is a 100% crop (the eye is from about 1/3 into the image circle's radius) captured handheld with the Canon EOS R5 at 1/200 sec., ISO 1000, and ... I'll let you guess the aperture. The RAW image was processed with sharpness set to "2" (0-10 scale) and very light noise reduction.
This result exceeds my expectation. Add slightly more sharpening (try it yourself — copy and paste this image into your image processing software) and the result is especially sharp.
