I have Manfrotto 055ProB legs with a 488 midi-sized ballhead.
The other day I was shooting a dark-field glass which entails precisely framing a black backdrop in the field of view. You do not want to have white borders around it nor want the black to be any larger than the FOV.
So taped a black card with the same ratio of my APS-C sensor on a white lit wall, screwed my 40D on the ball head, flopped the head so the camera was vertical and with a lens as light as the 50mm f/1.4 (and even more with the 100mm macro) exactly framing the black card was a nightmare. If I aimed precisely and then tightened the head it would slip. So by trial and error I had to aim a little higher hoping the slippage was just enough to precisely frame the card.
What would be the best solution ? Would some L attachment for my 40D body permitting to have it vertical with the ball head remaining vertical be the best solution ? Or do I need to spend an hefty sum of money on one of the more expensive heads ? Would they avoid that slippage in the same situation ? My heaviest lens is the 70-200 IS 2.8 but I seldom shoot with that on a tripod. More often use my 50 or 100 primes.
I often shoot in both horizontal and vertical setups and sometimes with the body parallel to the ground for macro work.
Would an entirely different type of head be better ? For sure the degree of freedom of a ball head becomes a liability when I want the camera to be perfectly level.
Thank you
Bob
