Okay, be that as it may, the shot still turns out more or less the same with a much faster shutter speed, which is great for sports.
is this unique to prime lenses or all lenses? if I had an M series zoom would I notice the same thing?
I've just tested this again here in the office, a shot of the corner gives me the following results:
ISO-200, f8
50mm - 1/30 shutter speed
18-55 stock - 0.3" shutter speed
This is a significant difference.
Not only that I'm noticing some slight color changes between the lenses.
The stock lens is the slightly blurry one
