Canon Extension Tube vs Macro Lens Decision

Canon Extension Tube vs Macro Lens Decision
I was recently asked to assist one of my workshop delegates with the purchase of a Canon EF25 II extension tube for his Canon EF 50mm f/1.8 STM lens (on a Canon crop body) vs the purchase of a Macro lens.

I obliged by capturing a small garden flower with / without the Canon EF25 II Extension Tube on a Canon 70D (also a Canon crop body).

At the same time I used a Canon EOS 6D (full frame body ) with the Canon EF 100mm f/2.8 USM Macro Lens and captured the same flower at the same apertures.

The objective was not really image quality, but for determining the absolute minimum focus distance for each of the body / lens (extension tube used) to flower (measured from the front lens element).

Selected Aperture on all 3 images = f/11 Different ISO's (Auto-ISO). More detailed EXIF data below the individual images.

All images are uncropped (with some Adobe Lightroom 6 processing).

Lens AF on for all images (No flash / handheld) Conditions: overcast.
