    Unfortunately I can’t tell what’s causing the problem in Autopano as I’m not an avid user of it. I use PTGUI since more than ten years for all my work and it never failed. Your images stitched with an average error below 1px.

    I agree that the 14mm is more versatile, but if you really need good images I’d not use such an extreme wide angle. Rather use something like 16-35 or 24-70 and for the panoramas a dedicated fisheye for 4 shots around. When you shoot in tight places the 14mm also might cause headaches with DOF.

    With the 14mm you will need at least 8-10 images to cover the sphere. Which also means more time shooting and processing.

    The stitch of the cinema looks good, I saw minor issues due to a blurred frame at the top.

    Sorry for the delay, I only now saw your links.
    First of all, the website of your sharing service is rated malicious by several browsers and Malwarebytes. This might keep people from proceeding any further. However, I took the risk and got the images. YOLO.

    All three sets stitch perfectly fine in PTGUI. I just droped them and let PTGUI stitch, not manual tweaking needed. I don’t use Autopano. So what is the problem with your stitch?

    Maybe Autopano get’s confused because the images do have a lot of overlap. Too much overlap probably.
    Also you should make yourself familiar with the concept of using manual settings for shooting panoramas.

    Sidenote: I doubt that the final result will make a big difference whether you use the 16mm or the 14mm.
    The 16mm has proven to deliver suberb results on the latest Nikon cameras.

    To understand what could be the issue you’d better provide a sample. If the error is not immediately visible please also describe what you think is not ok.

    I agree, the location is not mentioned all too often, but it’s on the IVRPA FB announcement:

    Doing aerials from manned aircraft is a serious business.
    If you need to mount something outside of a helicopter it needs to be done by a certified company.

    Handholding something outside of a flying aircraft with a weight of more than 1kg is not advised and also needs secure fastening. Do a dry run in your apartment and you will understand.

    Jürgen Schrader

    The distortion you notice is due to the field of view which is very large when zoomed out and rather samll when zoomed in. The effect is the same as with wide angle lenses and normal and telephoto lenses. There is nothing one can do about it unless one would find a way to change the laws of physics.

    Jürgen Schrader
    Jürgen Schrader
    IVRPA Director Member director

    Well, the limitation that makes us dream about rigs is physics rather than money.
    Everyone would love to have a one-shot-rig that allows high resolution panos without stitching errors, which currently is not possible to build.

    And once you start looking at stereo panos, the issue go through the roof.

    So for current rigs there is little left to wish for.

    Jürgen Schrader
    IVRPA Director Member director

    While there might be rigs one can dream of, There is no such thing like an ideal rig.
    One always has to configure a setup that best matches the current purpose.

    For panoramic photography a 4 camera rig will not make you happy unless you do aerial photography where the nodal offset doesn’t weigh in too much. For everything else it’s more like a pia.

    If you need to speed things up, a motorized head might come into consideration.

    I you need to shoot HDR spheres for IBL the Sony might not be ideal as at a maximum it allows 5 brackets 3 EV apart. I haven’t tested yet if that is sufficient to cover the entire range. That said I don’t know which are he maximum steps that the Nikon 8xxs do allow.

    The mentioned combo above currently is one of the best money can buy.
    The only alternative would be a Nikon 8xx series camera if you haven’t yet invested in Canon glas.

    As for the adapter, yes, I use the Metabones IV.
    Works nicely with the fisheye and TS lenses.

    The A7RII besides currently without doubt is one of the best bodies one can use for panoramic work.
    I’m using it myself mostly with the Canon 8-15 as this gives one all the options to shoot just 4 around or 6+1 with a very sharp lens that delivers to the 42 mpx sensor what it deserves.

    Depending on your budget and further needs there are other options available.

    It depends as always.
    You would have to specify your goals and the expectations of your client to get a more precise recommendation.
    Actually there is a huge gap between entry level cameras and “next higher level” equipment. Mind that you also will need specific software and editing expertise depending on the desired outcome.

    While you certainly will get more room for your camera with a smaller rig, you will not improve the noise/signal ratio nor image quality as you are still using the same camera technology but with lower resolution.

    I don’t think that someone can stitch a decent stereo pano on a smartphone^^.

    And yes, with ptgui it is possible but as I said it’s quite cumbersome.

    http://bavaria360.de/stereo/stereo.html

    In one of our recent conference videos (I think that was Prague) Jim Watters explains about how to do it.

    My methods are slightly different but that will get you started.

    There is no dedicated stereo stitching software. We use ptgui, but it’s a tedious process and needs special care while capturing.

    6) Sponsors should be allowed free social tickets for spouses especially if buying higher level of sponsorship or at least ‘highly’ discounted rates.
    Jurgen: As far as I remember the spouses tickets were always calculated at our self cost.

    How soon we forget – Vegas $450 spouse tickets could not be self cost at this price and was changed only after we opted out. This infers some would like to forget.

    I must admit that after more than two years I cannot remember every detail, but before I swallow that we’re brushing things under a rug I’d rather bother to dig out the facts.

    I quote from an email from Bill Bailey received on March 5th 2014, 06:42

    […] We are large group and up to now have been very supportive of IVRPA. Your systems are not accommodating to spouses or those wishing only a dinner and a breakfast. Your base ticket price is $500 plus the mandatory membership fee for “everyone” even those that will never have anything to do with IVRPA after the event. In the past the IVRPA has been very accommodating to “everyone”. But we understand new management and protocols and we’re not ones to create added work for others.[…]

    I quote from the answer, sent to Bill Bailey 20 minutes later on March 5th 2014, 07:02

    […] we as always have guest tickets which currently are not in the booking system simply because willy forgot to update it with the prices we determined. they will be added soon and these are the preferred way to accomodate spouses. […]

    […]our policies have not change since the last conference and there is no new system.
    just different people now who had to jump in and who are doing their best to match all peculiarities.[…]

    The email received at 06:42 ends

    […] We’ll review the numbers “as they are” to determine if this venue is worth the expense in moving forward. Should we decide to withdrawal I hope our $2500 paid is also refundable.

    But it was many hours later on that same day (16:35 to be precise) when we received the email from Bill Bailey where he cancelled participation and all sponsorship of the Las Vegas conference.

    So no rug and no changed policies.
    Fell free to ask all your questions.

    6) Sponsors should be allowed free social tickets for spouses especially if buying higher level of sponsorship or at least ‘highly’ discounted rates.

    As far as I remember the spouses tickets were always calculated at our self cost. Which means they pay for food at dinners and coffee breaks and transportationand entrance fees during excursions. There might be a small markup to cover cost for administration. So there is little to no room to cut these costs.

     

    15) Tally up what “active” sponsors have contributed during the life of the IVRPA and assign Lifetime achievement positions such as bronze, silver, and gold (as an example). […]

    I see no point in sponsors ranking. At every conference those who pay most will get the most prominent placement and most prestigious events. We never had a problem that sponsors didn’t get the recognition and value they desired.

     

    17) Allow sponsors not participating in a an event certain ad placement spots.

    This has always been the case. For example Klaus/Krpano never joined us at a conference but always has been a sponsor and got ads. Same applies to Joost/Ptgui who wasn’t always able to attend. Rest assured that we never reject sponsoring requests.

    While in general for your setup it is advised to shoot four around your result is a complete mess and shouldn’t look like this.

    If you always only use the 8mm then the R is the preferred choice.
    As soon as you want to go multi row you can’t use the R series.
    Mult irow is needed for panos with lenses above 10mm and will result in higher resolution.

    Unfortunately the lenses you have are anything but ideal for that purpose.
    To be honest, as a beginner you will have a hard time getting any useful results for interiors with these lenses. This is not to discourage you but to help you avoid frustration and giving up too early.

    Have a look at our ressources page, study the material and get back with your questions.

    So you are using a company’s free service and complain about them implementing a logo?!
    I’m sure the same will happen if you use other free services like 360cities, Roundme or Littlestar – to name just a few – and I’d say that’s only fair, no?

    The problem is that in a review you can’t simply compare functions as with camera models. We’re talking about entirely different concepts. To do these justice a full review would need a LOT of time.

    So better name the three leading tour building packages and the two leading stitchers and leave the rest to anyone’s taste.

    Or to make it short, get ptgui and pano2vr and be happy for the rest of your life.

    I suggest you learn to publish your own panoramas on your own webspace to get an idea what is needed and how much work that is before you offer that service for a client.

    As for the tours I think it depends a lot on how much emphasis you put on the photography part and how uch on the tour-building part. While you can cut on teh photogrpahy using a Theta, you will not be able to cut on the tour building as that in both cases will be the same.
