A Focus Checking Checklist to Run Through Before You Commit to a Shoot

Why decide on focus before the day

Focus is the one setting that cannot be repaired afterwards. Colour can be pulled back toward a match and exposure can be nudged, but a soft frame stays soft. That is why I treat focus as a decision to make before a shoot is confirmed, not a detail to sort out while the client waits. In these mid autumn weeks, with shorter daylight and more indoor events, the pressure on focus only grows.

This checklist is the one I give to studio owners and event videographers who run two or more cameras. It is written for the planning stage: each item is something you can verify with the gear you already own, in the room you will actually use, and tick off before you agree to deliver.

Go through it in order. If an item fails, you have learned something cheaply, at a desk or in the studio, instead of expensively on the day itself.

Check your monitoring tools first

Start with what you will be looking at. Peaking overlays are useful, but only if you know what they are telling you. Every camera draws peaking differently, and a high gain setting can paint an entire frame in colour even when nothing is truly sharp. Switch it on, aim at a flat wall, and confirm that it stays quiet when nothing is in focus.

Next, confirm your monitor or viewfinder is bright and large enough for the working distance. A small screen in daylight hides soft focus well. If the operator cannot judge sharpness at arm's length, add a shade or a larger monitor before the shoot, not after the first complaint.

Finally, note which camera models you will use and whether each one offers magnification while recording. Not all of them do, and that limits how you can check focus mid take.

• Peaking stays quiet on a flat, unfocused surface
• Monitor is readable at the real working distance
• Magnification works while recording, or you know it does not

Run a test target at working distance

A printed focus target is the most honest tool in the kit. Place it at the distance your subject will stand, with the lens at the aperture you plan to use, and shoot it. Then look at the footage on a proper screen, not only on the camera. Fine lines that merge into grey tell you the lens or the setting is not delivering what you assumed.

Do this once per camera and once per lens you intend to use. Two bodies with the same lens can still land a hair apart, and finding that on a calm afternoon is far better than discovering it across a crowded room.

Record what you find: distance, aperture, lens and the result. These small notes become part of your handover record and save the next operator from repeating the same discovery.

Confirm depth of field matches the brief

Sharp focus is not only about the focus ring. A wide aperture gives a pleasing look but leaves very little room for a subject who leans forward or a presenter who walks a step. Before you decide, ask what the people in front of the lens will actually do, and choose an aperture that forgives that movement.

Test it with a stand-in. Have someone sway, turn and step slightly, and watch the focus on your monitor. If the eyes drift out of focus within a few seconds, close the aperture or add light rather than hoping the operator will keep up.

Where several cameras cover the same subject, keep depth of field similar across them. Mismatched softness between angles is easy to spot in an edit and is hard to disguise.

• Subject movement is tested, not assumed
• Aperture is chosen for forgiveness, not only for look
• Depth of field is similar across all cameras

Plan how focus is checked during the shoot

Passing the pre-shoot checks does not end the job. Lenses warm up, tripods settle and people move furniture. Decide in advance who is responsible for checking focus during the shoot, and how often. On a two-camera setup that may be a quick magnified glance at each break; on a larger team it may be a named person.

Agree on a simple signal for the operator to call a problem. A raised hand or a short word over the headset is enough. The point is that nobody has to guess whether a soft shot was noticed.

Also plan what happens with a camera that cannot be monitored closely. If one angle is locked off and unattended, check it before the take starts and again whenever the lighting or the subject position changes.

The questions to answer before you say yes

Bring the earlier points together as a short decision list. If you can answer each one with a clear yes, the shoot is ready to confirm. If any answer is vague, that is the item to fix first, and it is usually quick to resolve when you catch it early.

Keep the list with your camera notes so the whole team can read it. A written record is also what makes the next shoot easier, because the answers carry over and only the changes need attention.

None of this needs special equipment. It asks for an hour of calm testing and the habit of writing down what you find.

• Can every operator judge sharpness on their monitor?
• Has each camera and lens been shot against a target?
• Does the aperture suit how the subject will move?
• Is there a named person checking focus during the shoot?
• Are the results written into the handover notes?
