Does anyone actually use the hard case? They just take up storage space! I have always maintained a decent camera backpack bag that takes the lens plus a body would be far more use.
It would be better to include a Swiss Arca QR lensfoot too.
Chosuan,I don't have any details about the field test, I was only told it was happening and if and when it came on the market it would be expensive.Very expensive.
Prices have risen sharply in the UK for whatever reason including the value of the £ falling against the US $.
With the 600mm f4 Mk2 selling at $11,499 in the USA and £11,349 ( =$14,000 US ) my guess is a 600mm f4 DO will be close to $20k. I was told a while back that it's being field tested but how true that is I couldn't confirm.
So unless you are prepared to shell out a small fortune I would consider...
