Early spring flowers

I was actually out looking for snakes using my 400mm and one extension tube to get some extra distance not to disturb the animals. The 400mm pictures are not macro so I do not post them here. On my way back I used my 100mm macro. The first picture is a Wood anemone (Anemone nemorosa). The second is ...

Nikon plan apo 20x 0.75

Many thanks to Adalbert that made a post about it here https://www.photomacrography.net/forum/viewtopic.php?p=258554#258554 Used as intended, with a coverslip, this objective performs nicely.

The nikon 300 needs a piece of tape to hold focus at infinity using it vertical. The nikon 400 might be to expensive. Another option is to use a teleconverter. Hope...

I just now grabbed a dust mite and sandwiched it between two coverslips and ran a stack with my 400mm Nikkor ED and 20x 0.75 VC on an S1R FF camera.. I'll post the results here shortly.

On my Optiphot microscope I use these lenses above 200mm Nikkor 300mm 4.5 Apo Ronar 360mm 9 Canon 400mm 5.6 Using a longer tube lens enlarges the image circle.
