Why High ISO and Multi-Autofocus Matters

One of the more interesting locations I visited in San Miguel was the Church at Atotonilco. It is a World Heritage site – and upon perusing its interior it is easy to see why.

However, it is anything but a museum. It is a working Church – and services are held regularly. And there are many worshippers present even when services are not being held.

And, there is no flash photography allowed – for good reason.

Hence, it poses something of a photographic challenge – as there is no loitering around to setup a tripod for a long-exposure. I managed to capture this and other photos simply by using the high ISO and multiple auto-focus points on the camera to get a good shot – in a big hurry with a 24-70mm f/2.8 lens with no image stabilization.

The results were fantastic. I have rarely succeeded with these types of shots with my previous gear.
