RJ Lens Turbo is most affordable among good lens turbo adapters.

It is reasonable sharp and useful for everyday photos and videos.

Adapters have some “blue dot” issue due to reflection from sensor with bright light being slightly outside frame.

So, you need to be aware of this and use lens hood always and plan the shot and all will be ok.

Available adapters:

• m42 to m43
• Nikon F /G to m43, with tripod mount ring, check photos above)
• Canon EOS (passive) to m43, with tripod mount ring, check photos above)
• Canon FD to m43
• Monolta MD to m43
• Pentax K to m43
• Pentax PKA to m43, for Pentax lenses without aperture rings
