GR Convertos image circle

I want to invest in GR optical converters, but I'm afraid that next GR model will not support them especially if GR is FF.
So my question is are those converters have image circle enough for FF.

I would doubt it. But I also doubt the next GR will be ff. One thing to consider though is that to use the conversion lenses you have to first buy the plastic barrel/hood combo to mount the lens on. If they happen to change this transition part you will be out of luck with your lenses....even if they stay apsc with the next model. Buy them and keep the entire kit as a back up to the new GR, or sell the entire kit to finance the new GR. If they work, sell the old body and keep the conversion lenses. Lots of options and too many unknowns. Oh, I have also read (not sure if it is true) that the conversion lenses are designed specifically for a given lens, so even if compatibility is maintained, the immage quality may be degraded.

I'm afraid I don't understand your comment. Did what stunt with the previous models?

Yes previous models were called "GR digital"

Yes, I am aware of that but what stunt are you referring to? Are you referring to the lack of compatibility between conversion lenses developed for the previous smaller sensor GR'S and the current apsc spec GR'S? If so that is not a stunt, but the inevitable result of the lens/sensor change.
