With its Arca-type compatible dovetail, the Sunwayfoto SPA-180 180mm Picatinny to Arca-Type Adapter lets you attach your Picatinny-compatible accessory to any Arca-type compatible receiver, making it possible to use a variety of items on a standard tripod head, and it is particularly suited for spotting scopes and other specialized optics. Measuring 180mm long, it has been precision-machined from hard anodized, T-6061 aluminum to provide an exact fit with no wiggle or play. Its hollowed-out design maximizes its strength-to-weight ratio by shaving off material while maintaining structural rigidity.

Related Questions and Answers

Q: 1. While it fits my RRS and Acratech ball heads, it slides on both. Am I missing a piece or is this not made for those ball heads?

A: The Oben SPA-1000 Arca-Type Smartphone Tripod Adapter BH #OBSPA1000 is made to attach to a standard 1/4"-20 tripod mount. It will not attach to a ball head.

Q: 2. Does this rail have laser etched or painted on marks?

A: I'm not sure how to tell the difference between painted and laser etched, yet the numbers that are present (on each side of the rail, as well as the top) appear to be high quality and durable. The nodal rail also has a nice feel (weight) in the hand, and is solidly well constructed. I'd recommend the purchase. The only thing missing is a marker system to mark your settings once you've establish them for your particular lens. My work around for this has been some black electrical tape to mark my key positions, or to write the numbers down on some paper I keep with me.

Q: 3. how much does the tripod weigh without the ball head?

A: The Oben CTT-1000 Carbon Fiber Tabletop Tripod weighs in at approx 12.5 ounces without the Ball Head.

Q: 4. Would the back knob prevent flipping the camera lcd screen such as the camera Fuji XT2 ? How many millimeters of clearance are there ? Would it fit the Hasselblad 500cm ?

A: The back knob will not be an issue with either camera because the quick release plate raises the camera bottom so it is higher than the knob. The clearance is likely 5-10mm.

Q: 5. Would this rail work well with a fisheye 8mm lens? I'm worried it may be a little too long. BUT I'd like to find something I can use for fisheye, 85 and my 50 mm prime.Or am I asking too much of one piece.

A: The DNR-120 is shorter and would be better for use with a fisheye lens. Please see the following link:http://bhpho.to/1n0MHt9

Q: 6. Hello, with this Nodal Rail is nothing more necessary? I mean, do I put the Nodal Rail on my tripod, and can I use it for panoramic photographs? Or do I need to buy something else to complement it with the Nodal Rail?

A: You would need two of the other rails to build the full panoramic shooting rig. An easier alternative would be to get an L-Bracket and a tripod head that pans.

Q: 7. Does this work with the peak design capture? or do i need to buy the dual plate instead?

A: This has an arca-type head, so it will work with the QR Plate that comes with the capture clip.

Q: 8. Has anyone tried this with an Acratech GP/GP-s/GP-ss ball head? I am thinking about saving some cash and using this nodal slide with my GP-ss with lever clamp.

A: I am sorry but the manufactures have not tested that Nodal Rail with that head. And Arca-Swiss heads are very precise and many items that are Arca-Swiss style will not fit as well as some other brands or its own brand.Best is to get an Arca-Swiss brand with their head.

Q: 9. Does this have an arca groove on top as well as, obviously, the bottom does? Can't tell by pics..

A: The Desmond DNR-180 Nodal Rail doesn't have an Arca groove on top.

Q: 10. I've read the 140 is too short for the Nikon 14-24. Is this long enough or should I go for the 200? Since I backpack a lot, every inch counts.

A: I have found this to be a bit short when I used it with a D800 and my Nikon 14-24. The Nikon D800 is so good and I have found that I really didn't need this to get good panos.
