Hello,I have a photoset of 600+ images with which to make a model but I made the mistake of using different focal lengths while taking the pictures. When I import them they are collated into folders of pictures with the same focal length. I have a point cloud as well; will this help in the construction of the model or not?
Thanks
Paul
Thanks Pierre,
I was able to generate a reasonably good model from those pictures and I don't think the focal length was an issue in the end. I was using an 18-55mm lens so I was zooming in and out but do you think that a fixed lens would give better results?
Is mise,

Hi Paul,
A 18-55mm lens can give great result, if photos are not blurry (shutter speed above 1/100 seconds) and well-enough exposed that will do the job without any problem!
To answer your question, in general a prime lens gives better image quality than a zoom lens. Having said that the gain is not so drastic to be honest. If you use a fixed/prime lens you could expect to get better chromatic aberration correction and sharper details in borders, and that will slightly increase the global accuracy and texture aspect...slightly I said :)

I probably wouldn't even notice the difference!
Thanks again Pierre,
