Stack two TCs on Sigma 500/4.5 (1 img)

Hi folks,

This is just for grins and giggles. Stacking two (2) Pentax 1.4X HD AW teleconverters on a Sigma 500/4.5 lens using a Pentax K-3. As usual multiply the focal length and aperture in the EXIF by 1.4X for proper readings. It is dark and raining outside right now. I just supported the lens on my porch railing to take this shot. The subject is about 300 feet. IMO stacking two 1.4X TCs work better than using a 2X TC. I have no other comments at this time.

Subject about 300 feet.
