Hi folks

I've been tinkering with hi res multi shot, multi row panos and would like some advice.

I have a NN5 which obviously allows rotation and tilting but it's not the most robust platform for big lenses like a 70-200 f2.8 or 300 f4. I have long Arca lens plates to allow me to move the lens further back on the upper rail but that introduces more flex in the system.

Naturally I could just use the lower rail for more stability but what about tilting for multi rows?

Full Gimbal heads like Wimberly will be strong enough but won't have the precision. A Gigapan epic pro would do everything but I don't want to buy one for what is just a hobby.

Any recommendations on beefing up what I currently have?
