Product Description

This is a new adapter with aperture ring inside for Canon EOS lens to Micro 4/3 M4/3 system cameras, such as Panasonic Lumix G1 G2 GF1 GH1 and Olympus PEN E-P1 E-P2 E-P3 E-PL1, etc.

The new adapter is design for want those who have Canon EF lens and also have mirror less camera to use EF lens on mirror less camera.

Important Notes

For bottom difference of Canon EF lens, this adapter doesn't compatible for Canon EF-S lens, such as:

EF-S 10-22mm; EF-S 15-85mm; EF-S 17-55mm; EF-S 17-85mm;
EF-S 18-55mm; EF-S 18-135mm; EF-S 18-200mm; EF-S 55-250mm; EF-S 60mm

We suggest Customers to rotate the ring from 1 to 6 to adjust the aperture ring in the adapter, if the position beyond 6, maybe dark area will be caused in the photos, for the reason that the aperture ring stay at the position is too small.

You can calculate focal index by below formula:
Focal index = focal length of lens / aperture diameter

Reference diameter at index (approx.):
1) 25mm
2) 22mm
3) 20mm
4) 17mm
5) 14mm
6) 10mm
