Canon 6D vs NEX-7 with Speedbooster

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. He had access to a multitude of manual focus lenses which can be used on both E-mount and EF mount (EOS). 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/2.8Sigma 28mm f/2.8Olympus 35mm f/2.0Sigma 50mm f/1.4
The images will show the whole scene at wide open to an aperture of f/11. It will be followed by center and corner crops at same aperture range. Here we go...

Sony NEX-7 vs Olumpus OM-D EM-5

We prefer all the advantages of the APS-C's sensor over the Micro 4/3 and that's why we shoot with the NEX-7.

The 135mm Lens Battle Combatants Part 1 for Larger Pictures
Here is the second part of our NEX-7 135mm Lens Battle. Part 1 discussed 135mm lens handling on the NEX-7. We tested three prime lenses (Canon 135/3.5 LTM, Konica 135/3.5, Minolta 135/3.5 MD) and two zoom lenses (Canon 70-200/2.8L, Olympus 75-150/4). The zoom lenses were set at 135mm approximately. The lenses tested are around $100 or less with the exception of the Canon zoom.
The shots were taken at wide open aperture (f/2.8, f/3.5, or f/4) and the at f/8. We have labeled each sample a color and a number. The NEX-7 or lens was on a tripod, ISO100, and JPG Fine output. The samples below are arranged as follows:
One is shot wide open. It shows the full scene with standard editing.One Crop is shot wide open with no editing. It is a 100% crop.Two is shot at f/8.
