Never get consistent results with it. I have fallen back to using a spyder lenscal and i can get most lenses calibrated in about 7 to 10 shots. Less if i'm already in the ball park.
Interesting. Do you have enough light and a stable setup? I keep my light in the 11-12 EV range or higher, and set up on a concrete slab (had vibration issues on the hardwood floor, moved to the basement). I get very consistent results, and they match what I got with the LensAlign, but FoCal takes less time.
Hey neuro yes we have discussed this in other forums. I wouldnt say focal takes less time when you consider set up, getting your lighting set up right...have a football field next door, etc....not to mention having to do it all over again when the results are not consistent. I no longer care to waste shutter cycles using the product.
