By nature the more you magnify a subject, the shallower the depth of field becomes but you managed somehow to overcome this issue... Gérard | To be honest, Gérard: I have no idea what lens this was. It was just by chance, that the husband of my girlfriend's sister came for a visit, he's a passionate photographer and had his 6,300 € Canon high end camera with him. So we decided to use it for some macros from my mineral collection. But really, I have no clue about the equipment, except for the fact that it was a very expensive Canon. But to be honest again: I don't care, I'm just happy that I got the chance to get some photos like that. But I can ask him about some data concerning the camera ;-)

Tobi, these images are pretty sharp and it would be interesting to know, especially if no focus stacking is used in the process.
In the meantime borrow that camera more often - looking forward to seeing more of your macros!

I got a quick response: It is a Canon EOS 1Dx with a 100 mm L IS USM-Macro.
I can't "borrow" it, he lives quite far away from me ;-)

Thank you, Martin! Actually these calcites were thought to be aragonite for a long time, but recent analysis made clear that they are calcite.

From a mineraogical point of view, the Blackdene specimen is the best because it combines four different minerals on one small piece of rock. However, I like them all and I'm glad that I could add three new specimens from classic localities to my galena collection.
Speaking of classic material, here's another new specimen that found its way into my small suite of English fluorites. Not a spectacular one, but a completely undamaged specimen of yellow fluorite from Hilton Mine with a water-clear twin at the top. Some of the fluorites include tiny crystals of a sulfide mineral, is this chalcopyrite?
Mineral: | Fluorite, chalcopyrite |
Locality: | Hilton Mine, Scordale, Hilton, North Pennines Orefield, former Westmorland, Cumbria, England / United Kingdom | |

Dimensions: | Specimen size 4,5 cm, largest fluorite 12 mm |
