Beautiful photos. The flowers are really popping out of the picture.
Can you please share a picture of your 90mm Rayfact lens, as theese lenses always are of high interest for me.
Best regards, Christian
Hilfreich? Unterstütze den DCC!

Thanks. Here are some pictures. I am not good at photographing lenses nor am I good at spotting the dust on them!Zitat von gladstone
This is the Nikon F mount version, less weatherproof than the others.
The inner cap is 52mm and the outer cap is 65mm (squeeze).
The first two images show the lens at all but very close focus.
The other two show it at closest focus with the lens extended.
The closest working distance is about 23cm at a field of view approx 75mm wide.

Very enjoyable. Nice timing with the last one.
Birch Shieldbug with Parasite Eggs
A Birch Shieldbug Elasmostethus interstinctus, carrying five eggs of a tachinid fly parasite. The parasite is likely to be Phasia species.
Olympus EM-1, Kiron 105mm at f16, twin RC TTL flash, hand-held. (2018).

True bug eggs and emerged nymphs 2021
I found this batch of eggs on a mint leaf. The nymphs hatched out a few days later and were huddled close together next to the empty shells, as is normal behaviour.
Olympus EM-1 (manual mode), Laowa 25mm f2.8 2.5x-5x ultra-macro at f11 or F16, twin TTL flash hand-held.

Schlumbergera microspherica Flower.
This cactus is a separate species in the same genus as the Christmas/Easter/Holiday cactus but its leaf-like stems are sub-cylindrical. It is overall miniature in comparison. I have had this species for many years, finding it difficult to keep alive. To my surprise it has now produced a flower.
The lens (M39 mount) I used arrived today and I found the inside (front) of the rear element has extensive but fine fungus. This was a test to see how much it might affect images. I have seen no effect here but the subject is not the best test. Anyway, enjoy!
EM-1, Minolta Rokkor f4.5 75mm, f16, 85mm extension, FOV 22mm wide, twin RC flash, hand held.
I took shots at f11 and f16 but none at f11 were sharp.
I can't remove duplicate attachment. The second one is not required.

und nun noch 2 mäßig Versuche für Long-Distance-Stereo, der Bildausschnitt ist tw. wenig optimal, das liegt daran, dass ich die Bilder beschneiden musste, um höchst verwirrende Vordergrundelemente zu entfernen (beim 2. Bild ist noch eins drin, das nicht ganz so schlimm ist). Die Stereo-Basis beträgt jeweils mehrere Meter.
