Hello I have a Canon 35mm 1.4L and I've noticed that the autofocus motor is showing some odd symptoms. Specifially, when I point the lens upward and focus it's REALLY slow and it shows on the distance scale as well. However, it seems to focus fine when parallel or pointing downwards. I've never really tried to focus while pointing up before so I've only recently noticed this possible issue. So is this normal on this specific lens or should I send it to canon? Also, my other lenses doesn't have any issues when focusing upwards.
