About speed (axis movement), if I understood correctly:
1. Speed depends on the power source. More voltage (until 15V) - more speed;
2. Papywizard use GoTo functions instead Touch controller and it's impossible increase speed (@fma38).
My understand, and I may be mistaken, is that none of these is going to make the mount very significantly faster.
If you want a significantly faster robotic pano head for shooting spherical panos you need to spend much more - the most versatile faster alternatives are probably the upcoming Panoneed from T&C and the Seitz VRDive 2.
In testing, it's take 3min 6sec from start to the last shoot for 4@-15+2@40 90dg op
That sounds like a long time - perhaps I haven't undertood your shooting pattern and number of shots - can you spell it out in more detail?
It sounds like rather more images that I would have expected to be required shooting witha Canon 5DMkII with a shaved 8mm Samyang fisheye lens.
I'm also wondering why you chose a robotic pano head gfor shooting spehrical panos with such equipment?
A manual pano head would have provided a much smaller nadir foiotprint and been quite fast to operate. Robotic pano heads provide most advantage when shooting higher res. (typically partial) panos with longer focal length lenses where many tens or hundreds of shots are required to cover the scene.
There are for main reasons why I want to use Merlin robotic head:
1. Great price-performance index + challenge
2. I wonder how it works. I love the 'smart' things...
3. It looks impressive to my clients and it can be better to charge.
(this is written by someone else on this forum too.)
4. Opens up new possibilities in the Gigapix panoramic photography that I have not tried to do, and I'd love to if / when I have free time.
My temporary preset for Papywizard is 6 photo: 4 every 90dg pitch on -15dg yaw + two 'semi zenit' at 40dg yaw on pitch 0 and 180dg. I was try combinations with 3 shots at 0dg, 4 shots at 0dg... There is problem with zenith (small black hole). So I was experiment with few combinations. Since I could not make with the Merlin zenit photo (mechanical limitations), I decided to do 2 'semi zenit' phots.
I own Manfrotto 303PLUS panoramic head to, which I used for cylindrical panoramas. The plan is to get a light Nodal Ninja 3 or 4 head and replace heavy, accurate but impractical Manfrotto.
