Hi Wishgranter,
I often work on archaeological sites so that involves being in environments with lots of mud, dust, water, … My lenses have to be good but also relatively low-cost so that I’m not afraid to use them in these environments and don’t kick myself in case one does get damaged.
Also I wonder how noticeable the difference is between one of the lenses I mentioned and the aspherical lens you linked? If I were to know that the cheaper lenses are absolutely useless for photogrammetry and won’t allow images to align then the aspherical one would of course be worth it. But I know you recommended the Tokina 16-28mm on Facebook so I’m assuming it’s not completely worthless haha.
The reason I still looked into the other cheap wide-angle tokina and sigma lenses is that they’re still significantly wider than the 16-28mm. Any reason that you’re aware of why these three other lenses would not work for photogrammetry?
Very grateful as always,
Thomas
