Thanks again to both of you for your time and patience.
The rental is certainly an option, but if my figures are correct I don't think it will be necessary.
I have only one more question to make sure I've correctly estimated the use of your products with my equipment. Since I don't want to make calculations every time I use the panohead, I've made a reference table to make life easier for myself, and to pre-visualize my use of the products.
The table contains only the focal lengths I intend to use (for the lenses I own), and only the panohead settings I will need for those focal lengths. The table may be unconventional but it is meant to be an at-a-glance reference customized for the RD-16 lower rotator and the M1-L upper rotator.
QUESTION -- Could you please look at two of the values in my table (one under the RD-16 column and another under the M1-L column) and confirm that the % overlap figures are in fact correct for the given degrees of rotation? If they are, then the others in those columns should be correct as well.
FYI When I used your calculator to compute my FOV figures, I found your "auto fill" values for the D700 sensor to be incorrect.
Your values: 34 x 24
D700 manual: 36 x 23.9 <--these are the values I used
The table was designed to answer the question.... Which Nodal Ninja detents should I use for multi-row mosaics, and what will be the resulting overlap percentages?
Results are limited to only those where the overlap percent falls between 25% and 49%. Any overlap percentage outside that range, it seems, would be less than desirable so I didn't include them.
The RD-16 column shows only those detents available on the RD-16 (lower) rotator, as degrees. Under the degree figure is the resulting overlap figure.
The M1-L column shows only the positions available on the M1 (upper) rotator as a "NUMBER" of click stops (NOT as degrees). Given that the M1 is limited to 7.5° increments, a number 2 would equate to 15° and so on.
Here's an example using a 70mm lens......
To pan side-to-side I have the options to set the RD-16 to 10° for a 48% overlap, or to 12° for a 38% overlap. To pan up/down I have the options to move 2 click stops (15°) on the M1 upper rotator for a 37% overlap, or 3 click stops (22.5°) for 25%.
If those figures are correct I can prepare my order and place it next week. Otherwise I will have to recalculate and review them again.

I'm located in the eastern US, any reason why I couldn't order from you instead of a reseller?
