Earlier this week my dealer contacted me to inform me that a customer wished to trade in a Canon 5D III that was never used [it was a prize] because he was a Fuji user. I had a look at the camera and it looked brand new so I purchased it at a very good price on condition that a GPS unit was included [the GPS is due to arrive later this week].
On the first day I used a Sigma 24-105 lens in fully automatic mode and I was really pleased with the results. However, on the second day I discovered that I could not get auto-focus to work in AV or TV modes which was a total mystery. After a few hours I discovered that the camera had been set up for back button focus.
Today I decided to use my Voigtlander 40mm F2 pancake lens which is totally manual and the results were not good despite the fact the lens works very well with my old Canon 1DsIII body.
Note: Once enabled, back button focus will mean that half-pressing the shutter no longer has an effect. All the shutter button will achieve is firing the shutter once fully depressed. Instead, the action of focusing is moved to a button on the back of the camera – usually the AF-On button.
