Today I tried it and from all the featuresthe new panorama stitching is awesome! First the usage is very simple. Select your images, check the preview and create the panorama without anyspecific settings.
The output qualitywas very good. I tried it onseveralprojects with pictures taken without a tripod and was very surprised. The processing time was short (about an estimated 20-50%of panotools on the same machine).
Some of my pano projects consist of multirow panoramas and all the input images were aligned correctly. Blending was similiar to the result of enblend.
As a long term user of the panotools I actually didn't expect anything like that. Setting CP manually, set t1/t2 to get everything right and have long disputes with the optimizer and run several iterations to get a good result. And then a fully automated solution getting similiar results.
