I had high hopes for the FE system, was thinking that I'd eventually switch from Fuji, but it seems the size and weight advantage are not there?

Filter Thread 72 mm
Dimensions (DxL) Approx. 3.15 x 6.89" (80 x 175 mm)

Canon 70-200/4 IS:

They should hire someone from Pentax to design the lenses.

use the canon version on a 36mp sensor and see what happens !

you want high quality , small in size, lightweight and cheap, sorry that's not feasible today

The centre of the Canon lens has been tested on 18MP APS-C, you'd need 46MP full frame to be as demanding. Its corners on 21MP full frame are not an issue. There are some A7R user using one with an adapter, ask them.


How much does the Canon weigh with the adapter? Dimensions added too?

You can carry one MB3 for all the EF lenses (mount the adapter on the camera A7/R), rather than adding an "adapter-tube" to each FE lens.  AF speed? Hmm . . .


Thats what I do (in fact, have EA2 and MBSB in my bag right now, so a lens can be used for two different FOV as well). You are already fine with a larger and heavier set up while accepting slower AF, we should expect 70-200/4G to be fast if not the fastest lens which will not be as large or as heavy set up.

Such discussions also seem to miss the point that we are talking about lens on camera and how the two setup together as a unit.
