Thought i should not contaminate the other thread picked a GX8 up today with 12-35 f2.8,in full frame terms its a 24-70 f2.8,secondhand but with 207 clicks only.
Just spent another £10 one of these so i can use my Sigma 105 on the new camera
Tried it and it works,the only problem is i needed 1000 of a second due to breeze and the ISO 3200 due to no light,i think it will be ok when the sun shines.
