The presets are useful because no two optical devices have the same adjustments. Your camera stores a “preset” that remembers the adjustments of any particular lens. Once you calibrate the lens, you usually don’t need to do it again. Accessing Lens Calibration in Your Camera So it would be best if you calibrated them again. The new camera is unfamiliar with the optical lens adjustments you made (and it might not be spot-on). Remember that you may need to calibrate your lenses again after buying a new camera. There may be no sign of damage on the outside (these things are tough!). You should also re-check your lens and camera if you drop them. Or it’s more likely if you get your gear second-hand after years of use.

But it’s much more likely if you use older lenses with new camera bodies or vice versa. The chances of having to do it are low if you buy everything brand new and at roughly the same time. You should check if they are calibrated correctly. That’s either with a specific lens or all lenses. Lens calibration should be done if you notice consistent camera misfocusing issues. It makes autofocusing quicker with adapted lenses in Sony and Nikon cameras. So they are not prone to misalignment problems.īut some mirrorless cameras offer lens calibration. Mirrorless cameras cross-check focus at the end of the focusing process. Note that you only have to do this in DSLRs. It tells the camera how to interpret the secondary sensor’s results… in a different way than the default. This process is an autofocus micro-adjustment. This ensures they work perfectly together. In both cases, you need to calibrate (or micro-adjust) your camera and lens. This can also result in misinterpretation by the focusing sensor. It will be blurred where it should be sharp.Īlso, some parts in your lens may not be exactly aligned with the required factory standard. Your final photo will show a shift in focus. In this case, something in focus on the autofocus (AF) sensor will not be focused on the imaging sensor. The problem arises when the two sensors are misaligned.

This process doesn’t check if the resulting shift places the subject in focus. And all light hits the primary (imaging) sensor. When you take a picture, the mirrors rise. It uses a technology called phase detection. The secondary sensor interprets the light and instructs the lens to focus in a certain way. Press the shutter button halfway to autofocus. And the rest travels up through the viewfinder to your eye. A part of the incoming light hits the secondary sensor. There are also mirrors that direct the light either to our eye or to the imaging sensor. In a DSLR, there are (at least) two separate sensors-one for imaging and a secondary one for autofocusing. The first thing you need to understand is how autofocusing works in DSLRs.
