Zeus was the second Galgo I met. He lives in Ohio:
Then, I met Lehto for the first time. He is nearly a year old and rail-thin. His antics are legendary, as are his looks:






I used an aperture of f/2.8 on all of these, which does not allow much room for focusing errors. But the wide aperture blurs backgrounds nicely.
