X2D Import Phocus / LR

[ALAIN]

Hello,
I'm starting to get to grips with my brand new X2D.
I want to develop in LR quite often.
I notice that .fff imports from Phocus weigh less than .3FR imports from LR: around 136MB/.fff compared to 212MB/3FR.
(Of course, the weight of .fff remains at 136MB once imported into LR)
Wouldn't the best import be done in two stages:
- Import of the case to the Mac by Phocus in .fff
- Import into LR always in .fff
?
We had already had discussions on this but now I find myself with heavier files than with an X1D.
For your information, simple LR development works at approximately the same speed as for M11 raw files, this with an old MacBookPro which is 7 years old.
See you soon,
Alain (from France)
