Saga makes high-quality flip diopter holders for just about any port. Constructed of anodized aluminum, they generally are threaded to accept 67mm diopters for most any brand.
The Olympus TG-6 camera paired with the Kraken Ringlight 3000 is a great compact set-up for shooting macro without the added weight and bulk of a tray, arms and strobes. The Ringlight 3000 can function as a continuous light source (up to 1800 lumens), or as a focus light with 3000 lumen burst capabilities. While using the Ringlight in continuous light mode, the camera automatically adjusts the exposure to the light output. However, when shooting in burst mode, there are some additional considerations and settings we recommend for getting well exposed images and make the most out of this compact set-up.
