So this is so fare the best setup I tested. I think I will adapt it for my 2 weeks holiday starting tomorrow. I will post some wildlife picture and probably film also.
Technically from Metabone, this become a ~10-17mm F2.0 (0.71x factor), but In really this give the same aspect has if you were using the lens on a Full frame camera (because APS-C are usually 2~3 times worse compare to full frame for noise VS ISO, it become almost the same because there is two time more light in the camera).
