You don't need any special effect for that. It's very simple in any advanced editing software. Just use two black layers (solids) and animate their Y position to mimic shutter motion.
Viewfinder effect is also very simple. Create image (inluding whatever you need to see e.g. center cross, speed and fstop numbers etc) in Photoshop and import it as a layer to FC Pro.
I use Premiere Pro, but I bet it can be done almost the same way in your program.
In FCP I'd do this:
Video is on V1, put a Slug on V2. Keyframe it to move from out of view above, to half way down, then back up out of view. I'd duplicate that Slug to V3, and rotate it so that it moves from bottom up and back down. Then go into SoundTrack Pro and find a camera shutter sound (there's more than one, all are great) to place there.
I'd also try putting the Soft Edges filter on the original footage only to get the most faint barrel effect of the lens edges.
