The standard rotaFoot for F-line and M-line ARCA-SWISS cameras, is $658-$708, depending on the bayonet. The larger GFX 100 rotaFoot is $1100, which includes bayonet and a 20mm riser extension block.
Both versions of rotaFoot have a specific model# for F-line Universalis cameras, since the function carrier mount is different. Pricing will be the same as either version above.
Additional bayonets for a second digital camera are $125 - $175. Again, price depends on the bayonet.
You must also have one of our dslr bellows with magnetic connection, pricing range $434 to $715. Bellows are available in wide bag 10cm, wide pleated Universal 20cm, Standard pleated 24cm, and long pleated 50cm. Bellows have not changed for rotaFoot, so if you have an existing bellows, it will work just fine.
