I just got my 6D back from B&H after exchanging the first one and had a question. I have just received a Spyderlenscal and took a shot at using it, but it was difficult to see exactly where the sharpest point on the chart was when viewing on my laptop. I could see that the top and bottom numbers were pretty blurry and it was difficult for me to see exactly where the sharpest point on the chart was. Has anyone else had this issue? I will admit that I was indoors and used my Yongnuo on camera to light the target since it was late and I don't have sufficient light indoors. The 6D was on a tripod at approximately the same level as the target.
