The Canon EF 135mm f/2.8 Softfocus lens is the first softfocus lens to be tested at DxOMark. Because it is not possible for DxOMark to compare this unique feature, we contrasted the EF 135mm f/2.8 Softfocus lens against lenses with similar focal-lengths including the Canon EF 135mm f/2L USM and the Canon EF 100mm f/2.8 Macro USM.
Canon EF 135mm f/2.8 Softfocus Lens Advantages:
• Vignetting is most controlled in the 135mm f/2.8 Softfocus lens, at least compared to its Canon relatives.
