TTARTISAN 11mm - Which Settings should we use for this new lens?

[Fotoatelier Ebinger]

Hi, 

we use the new Artisan11mm on our Nikon Z6. What settings should we use for this Lens? This one ist not listet in the list in PTGui.

Thanks, 

Andy

Hi Andy,

You're the first to ask. Could you make a set of images available for
download (for a 360 degree panorama) so I can add this lens to PTGui?

Kind regards,

Hi Joost, 

This is a new lens on the market - but pretty good. 

Here are some TIFF files for a 360 Panorama. It would be great if you can give me a screenshot with the settings for this lens.

Thanks for your support.

Until Joost ads the lens to PTGui, you would PTGui let determine the
necessary parameters. See https://www.ptgui.com/support.html#6_3 on how
to calibrate your lens.

Attached is my project file. You can see the parameters in the Lens
Settings tab, and save it to the lens database.

But it's strange, the lens optimizes to a 14.7mm fisheye, not 11mm. Is
your Nikon Z6 really taking full frame images, or is it perhaps set to
crop to DX format?

Kind regards,

Hi Joost,

The manufacturer of TTArtisan promote the Lens as a 11mm, but as you find out it’s nor really a 11mm … ist a 15mm. I´ve read a lot of articles and other got the same result. Its a wrong declaration of the lens and maybe a marketing thing.

Thaks a lot for your help.

Best regards.

Andy

Good to know. It looks like a nice sharp lens!

And it has equidistant projection, the only SLR lens I've encountered so
far. This can be desirable for panoramas because the angular resolution
is constant over the entire image.

Andy, I got a very good stitch using all of the images.  Project file attached.  In case you are not aware, you have images in mixed orientations (not just landscape and portrait) and need to take account of this in the stitching.  If you don't, you get small stitching errors here and there.  I avoided these by including the lens shift parameters for the zenith and nadir images in the optimization.  The optimization figures are then rather better.

Thanks for your feedback. 

Yes this is a really good and affordable lens for only 230 Euro ;) 

Is a (yet) unknown manufacturer from china. We are really impressed by the quality and the good construction. 

Here you can see the lens in a shop: https://www.foto-mundus.de/objektive/ttartisan-objektive/37747/ttartisan-11mm-2.8-fuer-nikon-z?etcc_med=SEA&etcc_par=Google&etcc_cmp=BF_Shopping_Generisch&etcc_grp=104012009476&gclid=Cj0KCQiAmL-ABhDFARIsAKywVac9nGOiLepBnxOq5pWRr6CP5e3xyMZ4RbBc5RlwGXY2ErQWdZRY9vgaAv3SEALw_wcB

Hi John, 

Thanks a lot for your help. You guessed right, I was not aware that it could be a problem with different orientations. I could not figure out how to get rid of the small stitching errors - so I hope this tip will improve my results ;)

Andy, An easy way to avoid these orientation problems is by switching off the auto rotate feature in the camera, if your camera permits this.  (The fault arises as a result of the orientation sensor not working when gravity is acting at right angles to the plane of the image sensor).  You can then rotate all the images into the same landscape or portrait orientation according to your preference in raw processing.

Can the TTArtisan 11 be used in portrait mode for a 4 shot panorama, or is there then not enough overlap for stitching?

You can download the project file in my response five posts above this one.  Load it into PTGui and since you won't have the original images, you will see a set of dummy images that you can arrange in the Panorama Editor window to trial various shooting patterns by editing y,p,r values on the Image Parameters tab.  With 4 portrait shots around you would have only 4% overlap, which isn't really enough.  Vertical fov would be about 132 degrees.

So better shoot 2 rows in landscape mode? Like +7.5° and -7.5° ?

It depends on the capabilities of your panorama head and whether you are aiming for full 360x180 coverage. I imagine you have a single row head with limited pitch angles.

John 

[Luc S.]

I ordered the fanotec R1, which can do minimal tilt, ideally full 360x180 but a small nadir patch is acceptable. Just wanted to know what is the ideal shooting workflow for that lens

If you are willing to do 2 rows, then you could try two rows of 6 shots at pitch +7.5 and -7.5 degrees, and with the camera rolled by 30 degrees to bring the diagonal of the image frame to the vertical.  That should give complete 360x180 coverage (includes the tripod, of course).

Thanks, will give it a try!

Luc, It just occurred to me that when you change the pitch on the R1, the entrance pupil of the lens changes position - causing parallax.  So not a good idea to shoot multiple rows.

John

[Luc S.]

Even if the R1 did not arrive yet i was thinking the same, as the pitch rotation does not occur at the NPP but will try if it can be adjusted/fixed... rotation on the z axis as recommended (30°)should work with a lens ring

Can those be mounted with an arca swiss plate if you want to use your tripod's own 'rotator' for example?

The 7.5 degree pitch (or tilt whatever it's called) i believe is mainly meant to eliminate the tripod head from the shot (when the lens covers a full 180 degrees), no? Though then i don't know why it can also point down as that would make it difficult adding images pointing upwards without parallax.

My first tests show that all what is needed is the lensring, in my case the one from Fanotec and a rotator. I bought also the R1 but think now its even not needed. In portrait mode you can already do a pano with 4 pictures, my tests tell me that 6 pictures slanted give the best result so far. I am impressed by that lens (especially for that price)

Luc

[MD]

For me its the other way around. The clamp on my tripod already rotates how it should, but if i wanted to use a lens ring (for its ability to rotate the camera diagonally), then i would need to raise it higher (and/or the slight tilt) to avoid getting the clamp filling the bottom portion of the image.

If i were to use Fanotec/Nodal Ninja's own rotator, then i can't use my tripod for any 'regular' photography the way i want to. 🤔

How does the coverage on top and bottom compare for you with images taken vertical vs slanted. Could you show an example?

Op zaterdag 3 april 2021 om 15:51:35 UTC+2 schreef Lauks:

On 0° slanted portrait you get a pretty small star on nadir and zenit. Apparently 7.5° tilt up and 8 pic slanted covers all zenit (but nadir star gets a larger diameter, did not try yet) with 6 slanted portrait 0° the star has around the diameter of the tripod if camera at around 1.60m from ground, no center column extension.

4,6,8. all work, i think the choice is depending on subject and work efficiency (that’s why i chose 6 slanted). All my tripods, cameras, rotators, all have arca mounts, so I can add or mount anything....

8 shots just to cover the zenith and blow up the nadir? That's a lot when the lens is capable of covering 360 degrees with just 4 images shot straight vertically. (at least mine does, samyang 8mm on apsc)

Good to know the limits of this star shaped method. Personally i think full coverage of the zenith is a must, so neither slanting or tilting the lens with a lens ring solves anything for me then, as i will end up taking an image up anyway. Which should also help to keep the stitch as clean as possible, rather than only having corners coming together there.

The TTARTISAN is listed at 11mm but is at 14.3mm using PTGui 12.21. I figured that the Canon FF would project at 11mm. I have been using PTGui for seven years and my trusty Canon 8-15mm always worked for me and assumed the TTARTISAN 11mm would be good for me. Unfortunately 14.3mm have too of the NADIR size. Any suggestions?

Hi Alan,

The TTArtisans are mislabeled, they have a longer focal length than
specified.

You might consider the TTArtisan 7.5 fisheye, which is actually a 9.6mm
fisheye.
