MFA Using Spyderlenscal Question

Hello,

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.

Thank you,

David

You can only do MFA when you have sufficient light to a) have a very fast shutter speed so that motion doesn't introduce error and b) have your lens wide open and/or your distance enough to create a thin DOF to make the adjustments.

Thanks for the tip! The 6D sync speed is under 200, but I felt that having it on a tripod and using the 2 sec delay would be sufficient. I was using my 24-105 F4 and at the wide end I was about 2 ft away and at the telephoto end was about 10 feet away, but the numbers/lines didn't seem very blurry so it was hard for me to identify the sharpest point. I'll try it again during daylight and see if I get different results. The primary reason for me doing it inside is becuse the inside of my house is flat compared to everywhere outside of my house.
