The finished z-stack, which contains more than 100 separate images, is then merged into one frame using the Helicon Fokus software. ![]() defraction doesn’t help beyond f5.6 tbh so it’s best staying at f2.8 or f4. These z-stacks can also be created by using a motorised focus rail and the Helicon Remote software. ![]() I do like doing things at maximum magnification (hence why I’ve been happy without an AF macro for last few years of mirrorless), so the lack of focus completely isn’t a problem. Captured using CameraPixels PRO, stacked in Helicon Focus One of the challenges in macro photography is the shallow depth of field (or DoF for short). A common problem in macro is lighting and a short MFD and big hood can be a disaster. I especially like how small the diameter of the lens is at the end. 1 Once I begin making series of focus-bracketed images (Nikon calls it focus shifting), I plan on licensing either Helicon Focus or Zerene Stacker to stack the images when Photoshop CCs stacking capability isnt sufficient. For those older cameras, Arsenal has developed an automated method to compensate. On the 2.5-5x laowa lens, it’s pretty special. Due to limitations present in some Sony cameras, direct control of the focus motor position is not possible on older cameras on newer cameras, Arsenal leverages Sony’s capabilities. This gave me confidence of having everything snapped correctly. In terms of why this over focus rail, it was mainly for testing, but having used a rail quite a lot over last 2 years, I have often managed a few missed shots that muck up a stack. I also used f4 whereas a tighter aperture would also have meant fewer shots of course. So no focus rail needed (although I did use one to get the foreground shot perfectly at the MFD of the lens for 1:1. I thought I’d share a few reasons for making this switch. Regards to helicon remote, it’s an app (I used tethered on my mac but mobile version also available) where you tell it the start focus and end focus points, it collects camera settings from camera and works out ideal number of shots, then cycles through, snapping, minute movement in focus, then snaps again. Helicon Focus versus Combine ZM for Focus Stacking I have used Combine ZM (and Combine ZP) for many years when I wanted to perform focus stacking, but I recently switched to using Helicon Focus. ![]() Stack shot is a great automated rail for macro stacking. The newest Camranger will micro focus the lens on the newer Sony cameras. I have considered acquiring a focusing rail to permit incremental movements between several images in order to achieve a stack. You’re all right, I probably went over the top with the 400 shots! That first shot though was around 30 degrees angle to the platform so there was a lot of depth from front to rear of shot. My new Sony 7 R 111 does not offer 'built in' focus stacking.
