Canon EF 20mm f/2.8 USM - Pros & Cons

Canon EF 20mm f/2.8 USM

The corners are also very decent at medium aperture settings
focusing ring itself is reasonably wide and easy to grab onto thanks
nice and fast
technical resolution is actually pretty good with a very sharp image center and pretty good borders
It feels mechanically solid and has FT-M which is excellent
Image definition is very good to excellent at all apertures
Build quality inspires confidence
fast
sharp and produces great colors
on par with their 20-35 and absolutely good
The price is quite reasonable
Images are vibrant and crisp
The sharpness is quite acceptable for these candid photos
the lens performs wonderfully

it was slightly wobbly in the tested sample
the lens suffers from a rather massive amount of field curvature
it does not have to travel very far between MFD and Infinity
an ultra wide angle lens
wide angles have long held a space in the bag of landscape photographers
The manual focus feel is nothing like a true manual focus lens
have unruly distortion which can be very distracting in an image
The slight mustache-style sub-frequency may have confused the software a bit here
will loose too much depth of field in the center of the image
the corners are very soft at large aperture settings
the MTF results are not directly comparable across the different systems
light falloff at the edges
None in the area of normal super wide angles
the corners are a bit soft at f2
The front element is slightly curved
of color fringing in high-contrast scenes
A bit weak in the corners
Equally questionable on full-frame bodies
obtain pictures that are sharp from corner to corner with this lens
the edge of the frame will not be sharp in the far distance
Not an optical marvel
corner sharpness was disappointing
