Nikon Z Series Sharpness Guide: Do Mirrorless Cameras Need Tuning? | FoCal

Is your Nikon mirrorless camera underperforming?

Even pro-level bodies and lenses can be 'off' right out of the box. Here is why your sharpest shots are still ahead of you.

Get your camera and lenses working perfectly together with FoCal

Your camera and lenses were each adjusted for the best performance when they left the factory, but until you put the lens on the camera, they've never been used together!

And, chances are, each came out the factory quite some time ago. Your cameras and lenses have been used, and that use had made them slightly different to how they were when they were new.

FoCal tunes your lenses to your camera, adjusting for all those tiny differences cause by wear-and-tear, temperature changes or even slight imperfections in your gear.

● Significant: Easily noticeable focus issues (tack-sharp detail is missing).
● Noticeable: Fine detail is "soft" when zoomed in.
● Minimal: No tuning required.

After Calibration

You'll see sharper shots, more in-focus captures and faster autofocus operation!

These are real results from real lenses. We capture these shots seconds apart - the only change is enabling the precise FoCal AF tuning values.

But… I don't need to tune mirrorless autofocus, do I?

Main components of a mirrorless camera and lens

Mirrorless autofocus isn't perfect…

Autofocus is performed using the actual Image Sensor in mirrorless cameras, so the biggest need to tune your autofocus is removed. But there's still plenty of things that can affect the autofocus performance:

  • AF pixel mask and microlens production tolerance
  • Lens optical path issues due to camera mount, lens elements, stabilisation systems and aberrations.
  • Wear and tear of lens drive systems
  • Missing or out-of-date internal calibration data
  • AF Processor algorithm decisions

All of these can be adjusted for by autofocus tuning with Reikan FoCal.

Reasons to check your gear regularly

Here are a few reasons why you might need to tune your camera and lenses:

Manufacturing Tolerance

Cameras and lenses are manufactured and adjusted before leaving the factory, but when you match your camera and lenses together, they may benefit from tuning.

Nikon Z7 II

Camera Handling

General use of a camera can cause tiny movements in the sensors and mounts. Big knocks and bumps can make checking and tuning with Reikan FoCal a must.

Nikon Z-mount Lens

Lens Wear & Tear

Over time, motors and gears can wear, making the focus position slightly inaccurate. Lens elements can shift fractionally causing slight focus errors.

Nikon FTZ-II adapter

Teleconverters & Lens Mount Adapters

Adding anything between the camera and lens increases chances of misalignment between the lens and body. Teleconverted and adapted lenses benefit most from fine tuning.

Changing seasons image

Temperate Changes

Hot and cold conditions cause mechanical parts in both your camera and lenses to move fractionally, introducing focus issues.

Mirrorless cameras don't need calibrating.

Wrong!

At Reikan, we've been gathering autofocus calibration results for almost 10 years now from users of our FoCal software, which includes data from users of Nikon Z-series mirrorless cameras… and it shows that you'd probably benefit from tuning your mirrorless camera.
