FLOWER PHOTOGRAPHY USING FOCUS STACKING ON OLYMPUS 

Also Comparisons between Full Frame and Micro Four Thirds, HiRes Images, HDR and Macro vs Standard Zooms

Flower photos taken to determine capability of Olympus's Focus Stacking feature on 60mm Macro and 12-100 f2.8 PRO Zoom lenses compared to standard Depth-of-Field photos on the same lenses and also against the Sony 24-105mm lens. 

Cameras on a tripod and using the same, focus point, although for some of the depth-of-field photos the focus point was moved for extra comparison purposes.

Also tried High Res images on Olympus vs the standard 42MP Sony images and using HDR.

The enhanced Depth-of-Field using the Olympus System can clearly be seen as an advantage. Although the Focus Differential (range 1 to 10) should be used at different settings for the two Olympus lenses.

Cameras:

Olympus OM-D E-M1 Mark ii with M.ZUIKO 12-100mm f4 PRO and M.ZUIKO 60mm f2.8 Macro Lenses.

Sony A7RIII with FE 24-105mm f4 G OSS Lens.

WHAT IS FOCUS STACKING

Focus stacking is a useful technique that allows you to get more depth of field in a single image. It can be done with any digital camera. You just shoot a series of images, shifting the focus a little between each shot and then merge the images so that only the sharp areas are visible.


Olympus uses in-camera Focus Stacking which automates the shooting and focus adjustment and merges the images in camera to create a composite that’s sharp from the foreground to the background.

The Olympus OM-D E-M1 range of cameras use this technique and the stack can be made of up to 15 images. In addition, a crop is applied because of the slight change in the framing as the focus shifts, is indicated in the viewfinder.
