@Greek_m43 : You should check the Lanparte Baseplate listed on the deals, very very good quality, and comes with two 30cm rods. You seem to have a decent tripod, but don't forget that the stiffness of the legs and head is the key to get stable shots.

@Greek_m43 : I use legacy lenses like yashica ML 50mm that are very similar to FD lenses (in size) and everything fit well on the 30cm rods. I can send you some picture if you want to get an idea.

Now my image shifting problems had disappear I noticed some vibrations when pulling focus, do you think using a whip can eliminate the vibrations ?

@mo7ies : I'm not using any IS, the vibrations come from my hand and the torque I apply to the FF. Basically all the movements you do with your hand aren't 100% steady, i think that's the nature of the vibrations.

Okay, I was planning to buy one of the good tripods listed on the deals, because mine is really bad. May be i'll have to weigh it down with sandbags. I thought a whip can eliminate the vibrations but without a good base (i.e tripod) it seems useless.

@tonalt True. In your setup, one can also place Varavon Lens Support upside-down on the top rails.

BTW, is there just one side bracket on the left? If so, the system might still have too much flex in it. May I suggest a cage with at least two side brackets, either on the same side or opposite each other.

@mo7ies yes there is just one, luckily I have one more. But it's tricky to place them correctly and at the same time get access to SD-card, open display to left, enough space for FF etc..

I knew there was a reason to order multiple gini rigs.. I got enough parts to build the ultimate rig ;)

I finally bought a very "decent" tripod kit, Manfrotto 504HD + 535K Carbon Fiber legs. Very pricey but I chose to only buy one good tripod, not 3 or 4 until I find something decent... I'm very happy with it, the shakes while pulling focus are only noticeable on ETC mode, panning and tilting are smooth.
