Thank for your feedback! But I do have a couple of followup questions, based on your feedback:
1. How are you mounting your targets to a tripod, i.e., equipment needed and/or photo of setup?
2. I have a couple of lenses that the focal length is not reflected in the FoCal distance chart, how do you determine the minimum focal distance in feet, e.g., EF 40mm, EF-S 18-55mm, EF-S 18-135mm, EF-S 55-250mm and EF 24-105?
Thanks again!!
I just used a three foot length of 2X2 wood with a slot cut in it to hold the target and I just clip the two lights to it to illuminate it. The wood piece attaches to the tripod with the arca style clamp. I'm not home right now so I can't take a picture of what my setup looks like. As far as the distance is concerned, the software will tell you if you are the correct distance and with zooms you always adjust for max wide and max zoom separately. In a Canon there is a separate MFA setting for each. Since I assume you have a cropped sensor camera based on your use of EF-S lenses, try the adjusted length (focal length X crop factor which is 1.6 for Canon) first so for the 18-135 use the distance for 24mm for the wide and 216mm for the tele.
