Reikan Focal

bbg404 · 17 Jan 2018

Morning all anyone used Reikan Focal to calibrate a lens and teleconverter??

Googled and couldn’t find anything to say it wasn’t compatible but it failed twice yesterday although the light was fading I just want to check if that was more the issue or if it doesn’t actually work

Thanks

Focal needs good lighting conditions to maintain focus on the target, otherwise you will get errors.

I was hoping that was the issue not the fact that you can’t calibrate once you introduce a TC

Thanks for the conformation

Definitely okay with TC's but of course you also need to watch the distance to the chart or you could be too close.
