PolarPro has been on a roll lately, releasing various lens filters aimed squarely at creative photographers. The new Shift Diopter lens filter is a collaboration with content creator and commercial photographer, Garrett “Shortstache” King. While a Diopter filter might not fully replace a Macro lens in your gear kit, PolarPro is hoping to reduce any potential points of friction during the creative process.
What’s a Diopter Filter Anyway?
The PolarPro Shift Diopter Lens Filter isn’t a new type of lens accessory by any stretch, but it typically comes in the “split-diopter” variant, which allows for two separate focal planes to be in sharp focus. The PolarPro SHIFT diopter works differently, with the effect’s emphasis on shortening the focus distance. A dedicated macro lens is often a specialized piece of equipment intended a magnification ratio of 1:1 or higher. They offer exceptional sharpness, a flat field of focus, and the necessary internal focusing construction to allow for use at very close distances. But these lenses also tend to be expensive, heavy, and/or have a limited range of uses outside of macro photography. If you’ve ever used Lomography’s LomoApparat or Lomo’Instant Square cameras, you might’ve seen a “Close-Up” filter accessory that came with your camera. While a diopter lens filter doesn’t change the actual focal length of the lens it is attached to, it does help to shift its focal plane, helping you to create creative images at focusing distances that wouldn’t otherwise be possible.
The PolarPro x Shortstache SHIFT Diopter will be available in +2, +4, and +8 diopters, allowing for creative control that can take the image from a standard shot to an intimate close-up in seconds, without the bottleneck of switching lenses. Like the PolarPro Artic CP filter, the SHIFT diopter incorporates PolarPro’s Chroma Film technology, which helps keep your image colors as true to life as possible – with no weird hue or color shifts. The SHIFT system will also incorporate the same traditional threaded mount with the option to use it with their Helix magnetic mounting system. Lastly, putting it all in a neat and branded package, the SHIFT Diopters will come with the signature green Shortstache pouch to keep them safe while in your bag.
Ditch the Macro Lens?
At the end of the day, the biggest question we have about a product like this is whether it can replace a dedicated macro lens. While that remains to be seen, I think a lens accessory like the PolarPro SHIFT system can be helpful in keeping a photo shoot moving forward on a budget, or simply by adding a level of flexibility to existing equipment, such as adding “macro” capabilities to a lens that wouldn’t otherwise have them (I’m thinking of my RF 16-28mm F2.8 STM for example). Ultimately, the PolarPro x Shortstache SHIFT Diopter appears to be positioned as the premium compromise—offering significantly better image quality than basic close-up filters, immense convenience and cost savings compared to a dedicated macro lens, and a versatile tool for capturing detailed shots of flora, products, or textures on the go. Its success will hinge on how effectively it maintains the resolution and sharpness of the host lens, truly making it a viable alternative rather than just a budget substitute.
