Sony A7 with Markins PS-A7 LS-A7 plate, PU-40 at LA-EA4 adaptor

Photo update for Markins PS-A7 and LS-A7 for Sony A7/7R camera. 

With Sony LA-EA4 adaptor with 85mm lens. 

I tried Markins PU-40 and would recommend it. 

Because of the unusual form factor of the LA-EA4 design, PS-A7 has to be removed to attach other plate (PU-40) and use it with quick shoe. (If you are hand holding, PS-A7 can stay there.)

Canon EF 600mm f/4 L IS I USM lens foot replaced with Markins LC-60

Lowering the mass center helps reduce vibration in a long teleport lens like Canon 600mm f/4 lens (IS 1 USM version in photo)

Markins LC-60 is for Canon's long teleport lens which replaces the original higher foot to a lower foot. 

The replaced foot goes inside the reversed hood.
