OK, this isn't what I expected, methodologies are always open to question, there are provisos and its a small sample so please don't shoot the messenger - he is simply trying to work out which kit does the job best!
Methodology:
Shooting a distant (between a third and a half mile away) scene, manually focussed on a Phase/Mamiya 645III (which has very jerky innards IMHO) with a Mamiya 150mm F3.5 lens. P45+ back at ISO 50. Shots were progressively taken as follows:
F16 1/13th Sec no MUP
F16 1/13th Sec MUP with 1 second delay before shutter
F16 1/13th Sec MUP with 6 second delay before shutter
Then shutter speeds of 1/25th, 1/50th, 1/100th/ 1/200th at apertures of F11, 8. 5.6 and 3.5 and at each combination, a shot with no MUP and with MUP + 1 sec delay and MUP + 6 secs delay. Cable release throughout. Tripod is a Gitzo Carbon Fibre GT3541LS on a stone tiled floor.
Every shot was done first as above with a Cube and then with the Manfrotto 410 geared head, which I rate but find ungainly. Both heads needed only minor levelling since the tripod was more or less level.
Provisos:
1) The Manfrotto shots were taken with a big, stable camera plate whereas the Cube shots were with the only plate I have for it, which is the Small Universal Camera Plate 1/4" with rubber top.
2) It's a very hazy day here and these were shot through (clean) glass. Light levels shifted a little throughout but I wanted to keep aperture, ISO and shutter combos comparable. All process in C1 initially, cropped and then exported to LR from whence to JPEG.
I let the results speak for themselves and will post some comparable frames in the successive posts.
