Re: Challenge: 50 MM shots only

A few I just came across. Taken with SD9 and SD14 using a Sigma 50mm f/2.8 EX 1:1 Macro lens.

.68ct Untreated African Ruby, very rare in the cinnamon color, especially rare to find an untreated one.

SIGMA SD14
50mm 6s F8 ISO100



~1ct Untreated African yellow sapphire with a slight green undertones. Another very rare stone.

SIGMA SD14
50mm 2s F8 ISO100



Lastly a ~2-3ct Color Change Garnet from the Umba Valley, even has a few crystal inclusions inside of it.

SIGMA SD14
50mm 5s F8 ISO100
