How do I compensate for lack of minimum shutter speed when in Av mode with the Canon 750D (Rebel T6i)?

There are a couple of things that I think that you can do: Learn your lowest shutter speed: At 24mm, I would have expected you to be able to hand hold 1/25 and especially 1/60. Now, that might be too ...

How does camera weight impact usable shutter speed?

The weight may have to do. The shutter has to accelerate quite brutally at the top, and gets rapidly stopped at the bottom. Both create impulses on the camery. Heavier cameras distribute the impulses ...
