      With every Gobe product purchased trees are planted in areas most affected by deforestation.

      As of November in 2019 we’ve become the sole sponsor of a site in Madagascar called Morangobe which employs 43 families but was at risk of being shut down due to a sudden loss of funding. We’ve committed to planting 100,000 trees per month in Morangobe to ensure restoration can continue there. Any additional trees are spread across our planting sites in Indonesia, Nepal, Haiti and Mozambique.

      The trees are planted by locals, providing vital employment while rejuvenating their world and ours.

No infinity focus on K1!Review by Daniel
I received my adapter today and was overwhelmed by the packaging and the quality of the material. Also, it smoothly fits to the mount. Since it does not focus to infinity on the K1(I tried different M42 lenses), its use is limited and very heavily blurs the overall impression. You can not offer your customers a product, that does not meet one of the most essential demands of a photographer. Sorry. (Posted on )
