    D-oh!
    That's nice of them; they only charged $20 for the app, now they will no longer update it.

    Yeah, this is a pricing model I really don't like.

    Regarding the wide limitations the Mark II supports wide converter lenses from ALPA, Schneider and olloclip - using them you can go up to 2x as wide as the phone alone would allow.

    If you have any further question, please feel free to contact me at support at direstudio dot com.

    On an Ipad Retina (4th Generation) the screen fits a 129 mm lens according Viewfinder Pro.

    Why not just look at the Ground Glass? If the view doesn't match your creative vision, mount a different lens or move the tripod.

    I bought the original app, which you have withdrawn, updated, renamed, and re-offered for sale.

    Support for the original app, which was around 20$, is no longer available, and it can no longer be downloaded from the iTunes store.

    How long will it be before you re-name this one, in order to attempt to re-sell it, and do you think that your existing customers will ever be tempted to buy from you again?

    It obviously would not work for wide angles unless there is a wide angle attachment for the lens.
    Well, you could measure the angle of view directly. Mount/clamp/strap the iPad to some support and view a scene . . .a brick wall maybe. Move objects on each side until they are just at the edges. mMasure that angle with a protractor such as is used in school (7th or 8th grade?). Now look up the specs on several lenses and see which focal length most closly matches that field of view.

    There is probably a better way to do this direct measurement, but this is what I can come up with just now. I welcome other ideas on how to do this.

    +1, but perhaps too obvious...
