Lately i have learned that there are special lenses called perspective correction which correct the perspective while capturing buildings that are near to us. The vertical lines of the buildings wont be slanted and look like they are falling backwards...
this seams like an unusual lens where it can tilt itself to correct the picture. At the mean time i know that Photoshop has also the possibility to do a perspective correction.
i was wondering if it makes sense to buy the lens which costs around $400 or just simply use the Photoshop? is there a big difference?
Is there someone using such a lens?
