Why do I need a replacement foot?

Long lenses such as the Canon / Nikon 200-400, 300 f2.8, 400 f2.8, 500 f4 and 600 f4 come with a very small lens foot. This is pretty useless when trying to mount to a tripod head as it's too small to centre the balance and can easily twist as it's just got one screw to hold it in place. 

So we made the BigFoot for you, our own range of custom manufactured replacement feet that we honestly think are the best on the market today.

It's all down to their low profile design. This lowers the centre of gravity so your heavy lens won't sit high up anymore like on other heads. Thus you will get a perfect balance with your Flexline head and the best possible balancing action. All have been manufactured to ensure that you can add 1.4x and 2x converters and still have enough play to set the centre of balance. Made for perfection.

They use your existing screws, take 5 minutes to change, have Arca Swiss plates built in.

So they are an ESSENTIAL purchase for you to get the most from your long lens and Flexline head.

Hints and Tips

Please make sure that you order the correct plate for the lens that you have as their is a difference between v1 and v2 Canon lenses!

Do not over-tighten the screws when you attach your plate, just hand tight is good enough as you have 4 points of contact.

Lens not listed?

It's impossible for us to make plates for every lens on the market, so we have concentrated on the longest and heaviest. Of course it is possible to mount lenses like a 100-400 or 70-200 onto the Flexline heads and we thoroughly recommend a third party replacement foot for these lenses. These are available from multiple sources online and will give you a much better option for getting the exact centre of balance with these lenses.
