Review on 📷 Fotodiox Lens Mount Adapter: Nikon Nikkor F Mount D/SLR Lens to Micro Four Thirds (MFT, M4/3) Mount Mirrorless Camera Body - Enhance Compatibility and Expand Your Photography Possibilities by Kwesi Delgado

This is a fantastic product. This is a simple adapter but you will effectively double the focal length of a micro 4/3rs camera. I tried this with a Sigma F-8.0 600mm SLR lens and it gave an effective focal length of 1200mm like a telescope. Incredible coverage. Then I added an old Tokink 2:1 doubler that turned a 600mm lens into a 1200mm lens, but on a 4/3 Micorean camera you double that back to a whopping 2400mm focal length . You lose two stops with that, so it's only good in bright light or slow shutter speeds. The only problem with such focal lengths is that every breeze will cause it to wobble. My old tripod was a bit wobbly. I'm tempted to build a concrete mount for it and try it out for stargazing and long exposures. Unstoppable fun. I then tried it out on a macro rail and mounted a regular Nikkor 50mm lens on a 35mm camera. So I actually had a 100mm micro 4/3 macro. I could blast a small needle to a giant size. I have a few other old Nikon F mount lenses that I want to try. For the price it couldn't be better. Metabone's Speedbooster works better but costs 20x more, I think I'll keep this one.
