Just a thought but why do you want a replacement foot?
I have owned the Canon 400 F2.8 L, Canon 600 F4 L IS and currently own the Canon 300 F2.8 L IS and Canon 800 F5.6 L IS - I haven't found any need to replace the lens foot on any of them.
In all cases I simply attached an Arca compatible QR plate and h#just got on with shooting. True an after-market foot (if it is Arca compatible) will save a few grams but it is a lot of money to spend for a VERY marginal improvement.
Just my thoughts.
Quite simple really, I don't like having a plate bolted on.
I had a 400 2.8 IS in the past and it had the plate bolted on. Nowadays my big white is the 200-400 F4L and I bought a replacement foot from RRS and much prefer it.
A few little reasons
- One less point of failure, replacement foot means no plate to come loose (the engineer in me would buy it for this reason alone)
- Weight savings, not much to count really though
- Fits in bags more easily and the original case more easily, I remember my 400 had to sit in a certain way with the plate for the case lid to close and lock correctly.
- More comfortable to carry the lens around when carrying by the foot
- More comfortable to hand hold, I remember my 400 2.8 was uncomfortable with the plate digging into my hands when hand holding.
- Looks better, I don't like the look of the plate bolted on and for a high dollar lens another hundred is not a big deal to have it looking the way you like.
I think I'm going to give the Kirk foot a try this time.
