A Bumble Bee (Bombus pensylvanicus) was on a Zinnia in Norman, Oklahoma, United States on September 2, 2021. I made this photo with a very old lens as an experiment. I purchased the lens in 2011 and nearly wore it out. For this photo, it was attached to a newer camera body with an adapter with two telephoto extenders.

The reason that the focal length is listed as 500mm for a 250mm lens is that a Kenko Teleplus HD C-AF 2X DGX teleconverter was attached. This photo was made hand held through a window from inside the house. F/11 is wide open for this combination of lens and teleconverter. The F6.3 listed is incorrect and two stops should be added. Auto focus was used. The combination of lens and telephoto converter confused the metering with a resulting very high ISO.
Firewheel wildflower (Gaillardia pulchella), June 5, 2018, Norman, Oklahoma, USA ; F Number	8.0 ; ISO	250 ; Shutter Speed Value	1/332  ; Focus Distance Upper	0.25 m ; Focus Distance Lower	0.22 m ; Lens ID	Canon EF-S 24mm f/2.8 STM

Blue Jay (Cyanocitta cristata) in Norman, Oklahoma, United States on May 5, 2023, EF100-400mm f/4.5-5.6L IS II USM +1.4x III, 1.6x crop mode and additional cropping to reduce size for upload

Northern Cardinal (Cardinalis cardinalis) in Norman, Oklahoma, United States on March 21, 2023
Glacier in Chugach National Forest near Whittier, Alaska, August 7, 2019
The reason that the focal length is listed as 600mm for a 300mm lens is that a Kenko Teleplus HD C-AF 2X DGX teleconverter was attached. This was taken hand held while sitting on a chair on my front porch. The gimp gmic plugin Richardson-Lucy deconvolution was used to remove small aperture diffraction blur. F/11 is wide open for this combination of lens and teleconverter. Focus was manual. After cropping and resizing to 40%, an unsharp mask was applied.
