Clip-on lenses for smartphones have been around for a while, but the Martvsen MagStack aims to provide a flexible macro option for smartphone users. The lens comes with a clip that can be attached to various smartphones, including the compact Apple iPhone 16 and the larger Samsung Galaxy S25 Ultra.
Additional Accessories Available
The company also sells a protective case for certain smartphones to help attach the lens securely. The main lens offers a 30x magnification and connects magnetically to either the clip or the case. Users can then add two to three extra lenses, each providing an additional 25x magnification, allowing for options of 30x, 55x, 80x, and 105x magnifications.
Clarity of Magnification
It is not entirely clear how Martvsen calculates these magnification levels. Based on the sample images provided by the manufacturer, the “30x” lens seems to produce results that are not much different from the macro mode on a standard smartphone. However, with all four lenses, users should be able to get much closer to their subjects, capturing finer details. At a working distance of just 2.5 centimeters, the MagStack may not be ideal for photographing live subjects like insects.
Crowdfunding and Pricing
Currently, the Martvsen MagStack lens is in the crowdfunding phase on Kickstarter. The lens and clip are available for a “Launch Special” price of $69. However, to access the full 105x magnification, users will need the MagStack Pro, which is priced at $99. These prices do not include shipping, import taxes, or customs duties.
The estimated delivery is set for November 2025. As with any crowdfunding venture, there are risks involved, including the possibility that the product may not reach the market at all.
