No idea! Smile Thesse snowflakes are about 2-3 mm in diameter.
We can make a little calculations - if smalests snowflake is 2mm, and camera sensor size is 22mm horizontally, and in the image snowflake appears as 1/3 from horizontal edge, so it is 7,3mm snowflake on the sensor. Than 7,3/2=3.65 ok lets say 3.7, so now we get magnification ratio of lens - 1:3.7. Next - magnification on the sensor (15x22mm) size is 3.7 times, if we enlarge this imaage up to 15x20cm (6x8in) print, we get magnification 37 times, if i look on image on my 21" monitor (30x40cm) than i have magnification 148 times Smile

That's fairly extreme! At least by my macro requirements it is. Laughing Laughing

I'm interested though, with two lenses head to head how do you pre-focus and pre-set the apertures? Do you end up working both lenses to get the final image or what?

I have only one light from flash medeling light (its dark outside), so, i focusesd with aperture wide open, and when im ready to shot, i stop down aperture unly ob first (from camera side) lens. Reversed lens gives strong vingetig when aperture is closed Smile

Lovely macros. Snow flakes are always interesting objects.

I must try some thing like this. Can I check how do you mount your two lens together? Is it with a adapter ring?

Lenses are mount with black scotch tape Smile

Thanks for sharing.
This is very nice setup you have here Smile And the snowflakes look so perfect !
Very Happy

Can you clarify what is the role of the 2x extender ?
It is a 2x TC right?

I was reading some time ago that typically for those reversed lens setups it's better to have a long lens on camera side and wide lens reversed in front of it.

Is that true ?
Please share your experience.

Thanks
Stefan

Yes, its true about telelens on camera, and wide or 50mm lens in front. Short focused lens works like a close up macro lens - 50mm lens is equal to +20D closup lens.
From my experience TC increase magnification few times. Nice setup is 135mm lens and macro rings between lens and TC. TC connects directly on camera. Smile

Good question... not sure ... i think that over 10x we could speak of micro, but absolutely IMHO.

Keep up the good work,

Beautiful!
I'm looking forward for some snow to verify my set up.
That would be one reason. Another one is that I love skating. So many rinks around me, last year almost every evening I was out skating.

These are really amazing, I've thought about trying to venture into this kind of stuff but have so far veered away because of the amount of time it seems to take. Great work and also clearly takes a lot of patience.

Just for info, taping lenses together obviously works very well but there are cheap double-threaded connecting rings available that screw into the two lenses' filter rings for those who prefer a more conventional link.

I really like the colour on these shots.
