Late last night I landed something I'd been fishing for this spring - a male Luna Moth. Here was a chance to apply the new Focus Bracketing from the 4.0 update on my X-T2, and I'm very pleased with the timing of Fuji's release and the resulting images. Some have questioned the practical utility of Focus BKT, while there have also been some suggestions that it is the latest fad. For me, it is an innovative new tool that helps me solve a frequent problem in the close-up photography of Lepidoptera - that is, making a sharp image from antennae to tail, wing tip to wing tip. Back in the film days, the trick was getting parallel as much as possible and using a small enough aperture for maximum depth of field - as much as diffraction would allow for, often f22. Almost always, it was still not enough and you had to be selective with your focus. Wing tips and antennae were frequent casualties. Diffraction is even worse with digital sensors that are smaller than 35mm and so stacking is a much needed technique to defeat it. And better still, when done correctly, it delivers the depth of field required for the entire subject - something that stopping down was never capable of. But it wasn't easy, at best you had a macro rail to assist you and at worst, you were carefully adjusting each slice by hand on your lens. With firmware 4.0 these kinds of images are much easier. It is still very detailed work and requires a good subject (not at all for chasing butterflies through the meadow), but it makes better results closer to reach. For that I am grateful, thanks to Fuji. Horizontal image: X-T2, XF80mm Macro, tripod, Fotodiox, 1/15sec @ f10, ISO 200, 9 images, Helicon Focus.
