Join Tim Grey for an in-depth discussion in this video Making diopter adjustments, part of Learning Photography: Autofocus.
- In general, my preference is to employ autofocus…whenever possible, just because it makes my work…as a photographer that much easier.…In situations where I feel the need to manually focus,…I like to make use of the live view display,…just because it makes the process…of manually focusing a bit easier.…But in some cases, I need to make sure…that what I see through the viewfinder is…an accurate reflection of the scene in terms of focus.…Fortunately, my camera includes a diopter adjustment,…which essentially allows me to change the focus setting…for the viewfinder itself.…
That is especially important, since I have…less-than-perfect vision, I need eyeglasses…to make sure that I can see clearly,…and if I'm using my eyeglasses, that's fine,…because I will see everything in focus in the viewfinder,…but those glasses get in the way.…And so, it's often very convenient…to take the glasses off and then look through…the viewfinder, so trying to make sure…that the diopter adjustment is accurate…will make it easier for me to work…
Photographer and educator Tim Grey explores these questions and more in this exploration of focus and autofocus. And because sharpness isn't everything, Tim also details scenarios where blur can have more impact.
