As much as I loved the Canon 5D (original) and Nikon D600, I can’t see going back to through-the-lens cameras. So useful is the digital focus assist of mirror-less cameras and EVFs. And the Sony cameras are small and light (which is both good and bad, but more good). On the wide end, I shoot with a Sony A6000 and 10-18mm.
Here’s one that I’m pretty sure was at 10mm, or 15mm effective
At a standard focal length, I’m using an Sony A7 with the 55mm1/8. The lens delivers images that often jump off the screen for me, especially shot wide-open at f1.8.
At a portrait focal length, I’m using an old Topcor 100mm/f2.8
I always love the $30 Fujian on the A6000 and should use it more. This is a throw-away shot while I was sitting near the Harvard Library during a walk.
