The methods of saving your adjustments vary from one manufacturer to the next. For instance, you have the option to save your calibration for an old 50mm lens and store another preset for an 85mm. The presets are useful, especially since no two optical devices have the same adjustments. Your camera stores a вЂpresetвЂ™ that remembers the adjustments of any particular lens. Once you calibrate lens, you usually donвЂ™t need to do it again. Since the new one is not familiar with the optical adjustments you made (and itself might not be spot-on), youвЂ™ll need to calibrate them again. Remember that you may also need to calibrate your lenses again when you buy a new camera. Even if thereвЂ™s no sign of damage on the outside (these things are tough!), some parts couldвЂ™ve become misaligned. You should also re-check your lens and camera if youвЂ™d dropped them.

The chances of having to do it are low if you purchase everything brand new and at roughly the same time.Д«ut if you use older lenses with new camera bodies, or vice versa, or if you get your gear second-hand after years of use, itвЂ™s a lot more likely. In general, if you notice consistent misfocusing issues on your camera, either with a specific lens or all lenses, you should check if they are calibrated correctly. Still, some mirrorless cameras offer calibration: this is to make autofocusing quicker with adapted lenses in Sony and Nikon cameras. Mirrorless cameras cross-check focus at the end of the focusing process as well, so they are not prone to misalignment problems. Note that you only have to do this in DSLRs.

Autofocus micro adjustment tells the camera to interpret the secondary sensorвЂ™s results differently from default. In both cases, you need to calibrate (or micro adjust) your camera and lenses to work perfectly together. This can also result in misinterpretation by the focusing sensor. ThereвЂ™s also a chance that some parts in your lens are not exactly aligned in the same way as the factory standard would require. Your final photo will show a shift in focus: it will be blurred where it should have been sharp. In this case, something that was in focus on the AF sensor will not be focus on the imaging sensor. The problem arises when the two sensors are misaligned. Take a look at our graphic that shows a simplified diagram of a DSLRвЂ™s insides. Then, when you take a picture, the mirrors rise and suddenly all light hits the primary (imaging) sensor. ItвЂ™s important to see that this process doesnвЂ™t check if the resulting shift actually places the subject in focus, because it cannot, by design. It uses a technology called phase detection. When the you half-press the shutter button to autofocus, the secondary sensor interprets the light and instructs the lens to focus in a certain way. A portion of the incoming light hits the secondary sensor, and the rest travels up through the viewfinder to your eyes. There are also mirrors that direct the light either to our eye or to the imaging sensor. In a DSLR mechanism, there are (at least) two separate sensors: one for imaging, and a secondary one for autofocusing. The first thing you need to at least vaguely understand is how autofocusing works in DSLRs.
