United Kingdom

Your software is fantastic and I recommend it to anyone wondering about lens calibration. I'm fortunate that I've been lucky enough to see a lot of the world - which really brings home how important it is to me to make sure I'm getting the best images possible when I use my camera - as it's not like you can easily do a 're-do' - it's almost akin to shooting on film as the screen on the back of most cameras is almost pointless.

I have tried all calibration techniques from all of the manufacturers I know of and by far the best is Reikan FoCal. I have been with them from the beginning and will stay with them in the foreseeable future. I cannot stress how easy and precise the adjustments are to use.

Staffan E

Sweden

I shoot a lot of documentary photography and focus is essential. I often need to capture a moment, a few seconds, that won't come back. There is only one chance to get the shot. That is why I am using Reikan Focal, to make sure that my lenses are as focused as possible. It makes me feel more comfortable and safe.

Joseph W

United States

I have been calibrating my lenses to my cameras with FoCal for many many years. I remembered reading, that the first time your lens and camera meet is when you bring them together. Cameras have auto focus fine tuning for that very reason. Before I go on any vacation, like to a National Park, I fine tune my auto focus. Instead of worrying about how crisp my photos will be, I have to be careful with how much sharpening I use in Photoshop.
