FINE TUNING YOUR CAMERA WITH A TAPE MEASURE

PREVIOUS / NEXT

PHOTOGRAPHY by KRISS on 05 march 2016

A lot of people are going to think I am mad for telling you this but having fine tuned all of my lenses on all of my camera bodies which makes approximately 30 fine tunings, I can assure you there are simple ways to fine tune your front focusing or back focusing camera and lens.

I used to print out a series of lines, set them at an exact 45° angle, put the camera on a tripod at ISO100, lots of light, tethered on a big screen, and everyone had to stop breathing in the house, blablabla.
Yes it worked, took me ages to set up and when I had a doubt about a front focus or a back focus I’d have to set up the whole thing again.

Well I actually simply thought about the way I do most of my photos, and since I don’t shoot tiny objects like jewelry for magazines, I realized my fine tuning had to work for what I do and it does.
I hold my camera with my hands 99% of the time so if there is any focusing issue resulting from my tiny moving when I release the shutter (which is not the case but I set this as an example) this should reflect on the way I set up my fine tuning.

So, my way is to simply get a measuring tape out, put yourself at angle between 30° and 45°, open as wide as you can and select one number on the tape and shoot.
Look at the image on the back of your camera, no need to import and waste time really, unless you’re tethered in a studio and that makes sense.
If the focus is on the wrong number, set your fine tuning to +20 or -20 and work your way down from there.


In about 5 minutes you will have set the fine tuning on your camera for your set of lenses and you’ll never bother about it again ! In our example, the Sigma 50mm f1.4 ART was back focusing with the Nikon D4s and still back focuses a bit after a +20 setting in the fine tuning which is the maximum available.
The number I tried to focus on was the 10 of course ! And if you’re not happy with it, you can always then spend the time to do it in the best possible conditions, but remember, this will probably not reflect the way you do most of your shots !
