Voigtländer Fixed focal length Heliar 10mm / 5.6 asph.

This Voigtländer 10mm ultra-wide-angle lens is suitable for full-frame cameras with e-bayonets and covers an incredible 130 degrees of field of view. The compact fixed focal length remains virtually distortion-free and delivers pin-sharp image results right down to the corners.

This lens can only be focused manually. Although manual focusing takes longer and is more demanding than working with autofocus, it does have some advantages: it allows you to focus precisely on the point you want, allowing you to take pictures that exactly fit your needs. Also in situations where the autofocus would be fast ?? demands - for example, in low light conditions, smooth surfaces with little structure or foggy weather - focus preferably manually.
