PENTAX K-1

I captured this image by changing the PENTAX K-1's Crop mode to the FF (full-frame) setting and using the DA 55-300mm lens. Although I detected some vignetting at the telephoto end, it was within my tolerance range. I set the camera's Clarity control function to Level 4 because I wanted to create a subdued tone. Unfortuantely, I don't know the name of this flower.
