Canon 6D vs Sony NEX-7 with Metabones Speedbooster Tarocoo wanted to see what the NEX-7 with the Canon EF to E-mount Speedbooster can do against his full frame Canon 6D .

The Speedbooster's final EFOV on the NEX APS-C sensor is about 1.1x the focal lenght - so the EFOV is close to the Canon 6D with the full frame sensor. The lenses used are: Sigma 24mm f/2.8 Sigma 28mm f/2.8 Olympus 35mm f/2.0 Sigma 50mm f/1.4 The images will show the whole scene at wide open to an aperture of f/11.

Sony NEX-5N vs Pentax K-01 Front View Here is the Sony NEX-5n with the Pentax K-01. They are only associated since they are mirrorless but that is where the relationship ends. The Pentax K-01 by Marc Newson is not really a Sony NEX competitor. It's closely related to the Pentax K-5 but without a viewfinder (optical nor optional evf) and autofocus speed. The K-01 and the K-5 use the Pentax K mount and share the same lens system. The K-01 loses the mirror box of the K-5 which makes it less expensive at $899 with the 40mm lens (60mm equivalent FOV) compared to $1300 for the K-5 with an 18-55mm lens. The closes Sony product is the SLT-A65 which is $1050 with the 18-55mm lens . Sony NEX-5N vs Pentax K-01 Top View Sony NEX-5N vs Pentax K-01 Back View
