2018-September-06.  Venus Flytrap Germination Photo:  4-week old seedling  (Copyright 2018 Makoto Honda. All Rights Reserved.)

 Nikon D300, Macro Topcor 58mm F3.5 with extension, at f/8 at 1/30 sec (daylight), ISO 200. Photo processing by Nikon Capture NX.
To reduce the possible camera movement, I used 5-sec self-timer and 2-sec shutter delay mode.
Also, with this magnification, the lens aperture beyond f/8 or f/11 will result in noticeable loss of resolution (due to diffraction).
