If you ’ve ever hire a photography class , there ’s a good chance you were instruct that when you ’ve capture clip to line up your shot you should always press the autofocus twice — or more time . Turns out you do n’t have to .
For those of you who might be a little scattered , let ’s take out the Push Twice Method a small piece . When you push your camera shutter put out button one-half direction , your camera ’s autofocus system of rules snap into action and adjusts the lens so that your shot will be needlelike . That we know . The idea is that if you take your finger off the shutter and push the shutter half way again , the AF system will mulct - melody the focus .
Turns out , that ’s some lensman hogwash . The camera buffs at LensRentals.comran a battery of testsand discovered that it makes no difference whether you autofocus once or doubly . Using a 50 millimeter lens of the eye , on both a Canon 5D Mark II and a Canon 5D Mark III , they tested the single - direction method versus the multiple focus method acting . The testers found that the asperity at the shopping center of an paradigm — as well as the average keenness of a photo — did not change using the multiple AF method acting .
That might go insignificant , but tip that focus clitoris more than once is a common technique . Not every photographer in the reality focuses this room , but a lot of people — incuding your writer , here — focus over and over and over compulsively . In fact , whenever possible , I take the AF off the shutter completely and represent it to a clitoris on the back of a DSLR — just so I can stumble it trillion of time .
look like we can all give it a rest .
