我覺得多左1 層納米結晶塗層有好大分別...在任可光線下表現比上一代都理想....

Frankie C-Hing,

May I be advised whether the PQ of the new VR lens is acceptable or not after adding TC17/TC20, please ?  

My experience with adding TC17 to AFS 300/4 is still acceptable, whereas it is not for the AFS 500/4 II lens.  If the PQ of the new VR lens remains acceptable after adding TC17/TC20, I may consider upgrading my AFS 500/4 to its VR version.  Thanks.

Frankie C-Hing,

Thanks for your reply.  Sorry, I dare not ask you to conduct a complicated test, just wish to know whether you feel comfortable to add TC17/TC20 to the new VR lens or not.  Anyway, your statement "...我用了三四次的感覺係E一代...一定係質數最高..." has answered my question already.  Thanks a lot.
