"In the case of the 50L (both of them), it was an intentional design decision by Canon."
Neuro could you please guide me where I could read more about this? Find this so difficult to believe. Thx.
In the press release Canon state that their target market is portraits, etc, which accounts for weak corner sharpness.
But they do not provide a sharp lens to people who want to shoot sharp portraits and sharp landscapes and sharp street and sharp journalism photos at wide apertures?
Are there not many uses to a sharp 50mm lens at wide f stop?
This is just not going down well with me. Am not being obstinate but find this logic incomprehensible.
