Hi,
I'm using a Sony ILX-LR1 camera with a Sony FE 85mm F1.8 lens.
The image alignment with this setup produces very poor results.
However, when using the same camera with a FE 50mm F1.8 lens, the alignment works well.
Are there any known limitations in Agisoft when using longer focal length lenses?
Has anyone else experienced this issue?

hello Jose,

maybe you can share a small data set of both cameras (50mm  and 85mm) so that we campare alignment results on this side...

Hello Jose,

If possible please also send the download link to the sample 85mm dataset that we can test to support@agisoft.com.

Hi, Alexey Pasumansky
I will send you the link by e-mail but also can share it here for anyone that want to try align the images:
https://transfer.sapo.pt/downloads/9c10ad94-03a6-404a-a3c3-3b4c8daef743/sapotransfer-63a7233fb817agb/

This is a ground test around a building, many times used for studies of 3d modeling and photogrammetry. The distance from the camera and the building was around 20 meters.
Using this images, agisoft can't return a good alignment.

The location of the building is:
latitude =  41° 6'24.41"N
longitude =   8°35'22.01"W
