## Overview

The DSLRKIT Lens Focus Calibration Tool is a compact, folding ruler (19x12.3cm) designed to help photographers precisely test and adjust their lens auto-focus accuracy. Compatible with Nikon, Canon, and Sony cameras featuring AF Fine Tune or Micro Adjustment, this pack of 6 cards enables quick, reliable calibration to eliminate front or back focusing issues, ensuring razor-sharp images especially when shooting with shallow depth of field.

## Description

Instruction This compact ruler allows you to determine if your lens is auto-focusing accurately as it should. It is an essential tool that is particularly useful when shooting with a shallow depth of field, where focusing should ideally be "spot on". You can use this ruler to determine how "off" the focusing is for a particular camera / lens combination and, on supported cameras, adjust the camera's auto-focus settings to resolve this. On Nikon cameras, this feature is known as "AF Fine Tune". On Canon and Sony cameras, it's known as "AF Micro Adjustment". Please refer to your camera's instructions manual to see if this feature is present. Size:19*12.3cm Package Included: Lens Focus Calibration Card X6 Usage 1. Set up the ruler. 2. Ensure both the camera and ruler are level, exactly perpendicular and at the same height. It is best to mount the camera on a tripod to do this. 3. Set the lens to the widest aperture to obtain the shallowest depth of field. This will make it easier to determine if your lens is focusing accurately. Auto-focus on the QR-Code at the center of the ruler, then take a photo. 4. Inspect the photo to see if focusing is accurate. It is recommended that you do this on a computer since you will be able to see better on a bigger screen. If focusing is accurate, the '0' on the ruler should be the sharpest point on the image and the other numbers get blurrier as you move away from the 0. 5. If any number above the 0 is clearer, then your lens is backfocusing. Otherwise, if any number below the 0 is clearer, then your lens is front focusing. In either case, you would have to set the auto-focus micro-adjustment parameters on your camera body until you are able to obtain a picture that is sharpest at the '0' on the ruler.

Review: Very good and very cheap! - So, it's a piece of printed cardboard. But it's good quality and much easier than the 'standard' way of fine tuning focus - with a yardstick/metre rule or tape measure at 45% resting against a target (google it for for details if you don't want to wait for one of these). Several different places to check focus against depending on how far out your focus is when you start, and it's very, very cheap. For what it is and what it costs, it's really, really good. And I don't quite understand how anyone can review something they haven't actually used(?). Instructions are in the detailed product description on desertcart.
Review: Ok but not perfect. - It's an ok wedge for lens calibration but not perfect due to not aligning fully when assembled. Good value as long as you are not expecting perfection.

### ⭐⭐⭐⭐⭐ Simple but effective.
*by G***D on 19 January 2024*

Works absolutely perfect for the micro adjustments on my old DSLR’s. Also tried it with my mirrorless just out of curiosity to check they really don’t need adjustment (they don’t, it was spot on the money!).
