I am rarely jealous, but here I make an exception!

How big is the image circle and do you have an aperture iris attachment or using it wide open.

Where do these come from?

Klaus,

This is above all a dream and a wonderful community metaphor. What other lenses can turn the background into such a delcate flowery mist?

Klaus,


What plants are these? I like here that we have circles made in the b.g. Why is one picture showing diffuse soft bokey and this one giving the clouds of suspended circles. Is it becasue there are small strands of pnats just behind the flowers that cause the round artifacts?

Hi guys, thank you!

Asher, first about the "circles" aka bubbles question: the lens usually gives a ver smooth BG, except one shoots against highlights (here reflections of the rain water droplets on grass and Croci), then the bubbles appear.

I search russian sites, there I find those goodies at times. This one is really special, as it is a prototype and has an adjustment ring which allows to control the spherical abberation of that lens. Similar what the Nikon 105mm f2 + 135mm f2 DC-Nikkor allow to do.

That lens is a projection lens, hence has no iris and control is done only by adjustig the exposure time.

All fast lenses usually deliver this kind of smooth background rendering and shallow depth of field, , hence why I am so after them, especially those fast projection lenses.

I hope you can recommend some that are able to adapt to the EF mount as then it could work ion my Fuji GFX. The 18 mount from the Russian lenses seems to need an abulity for the barrel to rotate and so I think I would need the 19 type fitting....or are these the designations for the cine lenses only?

Sometimes all it needs is a slight change of angle...

This from about 30 degrees:

and then this shot closer to the ground, nearly horizontally:

I have always been fascinated by the images you produce Klaus, as you know.

You make searches in Google, right ? ebay also... and so on :)

And there is always need for an adaptor ring...

Yes, they call me "Lens Sherlock" as I can find what no-one can :biggrin:
It needs perseverance, determination and the willingness to wait long enough,
sometimes many years....

And yes, my best friend is my mechanic, we always have something to do, he is
very similar than me, our birth date is just 2 hours apart ;-)
