Not as good as it used to be. – CameraPixels Review

As a semi-pro landscape photographer, the older version would zoom the view when manual focusing. Latest version does not and focus peaking is useless on such small sensors with limited sharpness and lots of depth of field. The app also now outputs DNG files in a random alphanumeric string. If you shoot a burst, the files are not sequential when loaded in the PC. I love how it does focus stacking with exposure bracketing. Overall great app if they brought back manual focus zoom and fixed the file naming issue.
