Does anyone have feedback on the Kodak Lens IDS digital measurement device . Also, looking at the M'eyefit, Otto and optikam ipad digital measuring tools. We primarily use Kodak lens and it would be the most cost effective option, however not sure on the reliability of the measurements?

From what I have read so far the Optikam and M'eyefit are pretty reliable however the otto device is suspect. Have not received any feedback on the Kodak device. Thanks
