got an IM question and tried to answer, but i am not sure that it worked. I could not see that it was send. So try to do it this way: I just used Google translator to translate english to arabic. I hope it is nothing in there like "put the camera on the grill before you start shooting. The mail looks funny, but I hope for somebody who does not speak so much english it might help even with " the camera on the grill" . Thanks a lot for your understanding guys.
to get the lower rail setting with and without battery grip, you can just measure the height from the table to the small silver pin on the right hand site of the Nikon and Canon bodies. The rest might have something like this as well.
Mount the grip and measure this distance. Then add 13mm for NN5, 14mm for NN3 ( I will set the 14mm sharp this weekend). This is your lower rail setting.
this is your second comment about "this is not correct".
Reading another comment about this thread from you I think till now you did not understand of what I was talking about. I am not talking about thickness of camera plates. Cp - CP2. Nick is an experienced designer, knowing that if he would change the size of CP to CP-2, this would have changed the lower rail settings. So, this is still the same measurement. Thx Nick.
I try to explane my thoughts for you Hans.
I try to find out principles for lower rail settings to help newbies as well as experienced users: what about a new lens or camera body? What is changing? Nodal Ninja products from camera to camera? Not at all.
To find the lower rail setting you need (H) , you know the database, http://wiki.panotools.org/Entrance_Pupil_Database, plus the "Offset" of the NN product from the (H) to the corner of the vertical rail which gives you the lower rail setting. When you have a look to your brand new product, you might realize setting upper and vertical rail on the same niveau, that there is an offset to the corner of the vertical rail to the touch point of the camera mounting plate >10mm+"measurement of the whaterver plate".
This is what I am talking about. I try to make things simple for newbies by looking for principal of the whole system. Set this in a database "how to find". Not talking about thickness of CP's. Be sure I tested this before writing a comment.
My personal conclusion, to find lower rail settings easily and test them with your own equipment, measure (H) of your camera and add the offset 13mm for NN5 and 14mm for NN3. I tested this with my brand new equipment NN3 and
my "old NN5". I like it.
I will add a photo, I think everybody can read this.
Anybody who tries to tell me I am wrong, I feel free to accept a proof!
Hans, and all the rest of experienced followers on panophotographie, let us try not to get newbies weared with our comments.
Whenever we'll meet, a accept a champagne from you for excuse. I like your knowledge and comments on several forums. But I set a stop when I feel there is something wrong.
though I am a Nikonian, though I hate battery grips cause of offset in vertical horizontal cause of "plastic equipment" making the camera to move off of the vertical etc, offset in upper rail settings related to offset of the tripod mount Camera Battery Grip:
I asked canon support about the (H) of battery grips which have to be adde to the (H) of the body to find the lower rails setting, an incomplete answer but they answered!
Canon 450D, 1000D, EOS XSi, T1i the height of the additional (H) of the Body is 114,3mm, so 115mm,
Canon 5D MK II add 103,1, so try H 103.
This is my way to "try to keep it simple" . Because the main point is to go out to shoots on it's best.
Sorry Heinz but something is very wrong with your measurements for the NN5.
In your first post you claim.
"In the wiki databse you will find 43,5mm for (H), which means from the bottom of the body to the middle of the lens flange/mount. For the NN5 just add 13mm to get thelower rail postion of the vertical rail."
This was before I got the new NN5 with the CP2 and it lead me to the incorrect conclussion that the CP2 was adding 13mm instead of 10mm as the old CP1.
So thats why I corrected it. Your images on the first post does not work and I had no idea what your measurements was on it.
Do you really have a NN5.
If so it must be a different version than the 2 I have.
