Overall the Canon generally handles backlit conditions perfectly competently,
aided in difficult lighting by its deep lens hood.
Occasionally though it does run into serious issues with a strong light source either within,
or just outside the frame that isn't shaded by the hood.
With the sun in the corner of the frame we see extensive flare patterns
which increasingly more defined and obtrusive on stopping down, whereas with the sun outside the frame
but still impinging on the front element, there's a noticeable overall loss of contrast.
To be fair this isn't a particularly unexpected performance for this type of lens,
and whilst these issues are easy to demonstrate when explicitly looking for them,
they're unlikely to reflect very common shooting situations for many users.

逆光性能が芳しくないから、フードを深めにしてみました。ってこと？よくわかんない。
