Summary

Updated with the new selectable 3, 4, 6, 8 click stops. Photos have not yet been updated.

The Ultralight Panohead is compact, lightweight, and easy to use for shooting 360° x 180° spherical panorama photos. Originally designed for extended hiking and bicycle trips, the new design with click stops is adaptable for use in multiple scenarios.

This version is for use with the Samyang 7.5mm MFT Fisheye Lens, which also goes by the brands of Rokinon, Walimex Pro, and Bower. The lens has a mount for Micro 4/3 cameras, and can also be adapted for use with other cameras that have APS-C and Full Frame sensors using a mount adapter (not included). A panorama can be completed with a Micro 4/3 camera in 6 shots around and 1 hand nadir shot (zenith optional), and with an APS-C camera in 4 shots and 1 optional hand nadir with the lens hood shaved.

Image Type
Micro 4/3 sensor (2x crop factor) produces a rectangular image with approximately 175° FOV corner to corner, which requires the lens to be shot diagonally and 6 shots around. There is a star shaped nadir hole, which can be reduced if shooting 8 shots. APS-C sensor (1.5x crop factor) produces a partially inscribed circular image with approximately 185-190° FOV diameter, which can be shot in portrait and 4 shots around. There are no zenith or nadir holes, as they are both completely covered. However, the lens hood needs to be shaved, and a M4/3 mount adapter is required to the specific camera being used. Currently, there are adapters to Sony E-mount (18mm flange focal distance) available from several sources online. It may also be possible to use a Canon EF-M (18mm) and Fuji X (17.7mm), as they are shorter than the M4/3 (19.25mm), however these adapters are not widely available. Modifications are done at your own risk. Full Frame sensor (1x crop factor) would only require 3 shots, as it produces a completely inscribed circular image. However, the lens hood needs to be completely removed, and a mount adapter is also needed. Since the hood is completely removed, the lens cap would also need to be modified. Modifications are done at your own risk.

Shooting Tips
Clicks: The rotator has selectable clicks of 3, 4, 6 (default), or 8 stops. Please refer to the instruction manual on how to change to a different number of stops. Aperture: The Samyang 7.5mm MFT Fisheye Lens is sharp between f8 - f11. Below f8 it tends to have softer edges and stitch seams. A useful feature of the Ultralight Panohead is that the aperture and focus rings are free to adjust while the lens is still attached. Rotator Lock: When shooting 360 videos or time lapse, unintended rotation can be prevented by using the rotator lock. It is designed to only resist the weight of the camera against gravity. It is not intended to resist rotation by force. Finger tight only; do not overtighten the screw or attempt to rotate while locked, or damage may occur.
Control Points & Lens Shift: During stitching, your software may create control points which could cause misalignment. There should only be control points between adjacent images. For example, image 3 should only have points with 2 and 4. If 3 and 5 have control points, delete them. Also, for a better stitch, the software optimizer should aways be set to "Heavy Lens Shift." (Software is not included) HDR & Exposure Fusion: When shooting scenes with a wide dynamic range between shadows and highlights, multiple exposures can help create a more evenly exposed shot. This would require the use of a tripod, and it is recommended to use a shutter release or remote control to prevent moving the camera during shooting. Cameras with Auto Exposure Bracketing (AEB) is a helpful feature. Always shoot in full manual mode and manual white balance, and optionally shoot in RAW format for better image quality. Mobility & Monopods: Shoot with a monopod for quick and easy panoramas. Single exposure is only possible, but usually this would be taken outdoor where the lighting is more even. If it is dark, you can increase ISO, as long as you are able to shoot faster than 1/30 to 1/60 seconds. To keep the lens as close to the nodal point as possible, look at the built in bubble level, or use the Manfrotto Autopole Spirit Level which can be attached directly to the monopod (not included).

3D Printing Technology

The upper part of the panohead, is printed with Selective Laser Sintering (SLS), which is a method of producing a physical duplicate of a 3D model by using a laser to fuse together particles of powder. The material used for the Ultralight Panohead is a strong Polyamide 12 nylon (PA2200 Material Data Sheet).

When it comes out from the machine, the surface is white and has a rough feel, because the nylon particles are about 60 microns. The parts are then placed in a tumbler with ceramic media for several hours until they are smooth. It is then colored in a vat of black dye for an hour. Afterwards, a layer of 2 component polyurethane clear coat is applied.

TOM SHOT 360 Ultralight Panohead, Samyang 7.5mm MFT shaved lens cap
Summary (Total Time: 45 min; Cost: $25)

To use the Samyang 7.5mm MFT fisheye lens with a Sony NEX camera you will need to shave the lens hood, remove shims, and attach a Micro 4/3 to Sony E-mount adapter. It may be possible to fit this to a Canon EF-M-mount or Fuji X-mount, but you'll have to find the appropriate adapter. The modifications are very easy to make, and takes about 45 minutes to complete. It is done at your own risk.

Shave the Lens Hood (20 minutes)

Remove the black metallic label ring. The ring is backed with adhesive tape, pry gently. Then remove the three screws which are revealed, and the hood will come off. You need to completely remove the short shades of the lens hood, and shave about 3mm off the top and 1.5mm off the sides of the large shades. The large shades are needed to attach the lens cap. Draw a line along the intended cuts, clamp ($3) the hood to a table, and use a hack saw ($4) to cut a little bit less than intended. Use a nail file ($1) to remove the rest. Check intermittently with your camera to see if you have shaved enough of the hood so that you no longer see it in the image. Clean off the dust each time before reattaching.

Remove Shims (10 minutes)

The thickness of the Micro 4/3 to E-mount adapter could vary slightly than the needed 1.25mm thickness. If the adapter is thicker, then the lens is pushed forward slightly out of focus and you need to remove shims to bring it back. My adapter is 1.60mm thick, which is 0.45mm more than needed. Unscrew and detach the mounting plate on the back of the lens. Inside you will find multiple adjustment shims. My lens has 2 shims, 0.3mm and 0.05mm thick. You may find more in your lens. Remove one at a time until focus to infinity is achieved. Removing both shims was best for me. Focus to infinity (hyperfocal distance) may change and is usually achieved when the focus ring is set slightly below the infinity marking. In case you need to replace the screws attaching the lens mount, they are M1.6x9mm with a 2.5mm diameter flat head machine screws, which you can find on online micro fastener shops.

MFT to Sony E-mount Adapter (2 minutes)

You need an adapter to attach the MFT lens to the Sony NEX. The adapters from eBay ($15) may be machined slightly wider than necessary and the lens sits a little loose inside the adapter. To make a tighter fit, insert the end of a screw driver into the slot inside the adapter mounting tabs to widen it. Do it slowly and in increments, checking intermittently if you are getting just enough tightness.

Shaving the Lens Cap (10 minutes)

You will also need to shave the lens cap, the same distance that you have shaved the hood.
