I will soon have lenses for all the different areas I photograph but it made a lens for landscape photography. I have looked at the Sigma EX 10-20/4 0.0-5, 6 DC HSM and Samyang MF 14/2, 8 ED AS IF UMC.
Both lenses have the same price (new from store). I am aware that the Samyang is manual and does not send any information to the camera, but it is also much sharper at both low and large aperture.
Someone who has more experience of these two lenses?
