I am not using 1.4X TC, I am using 1D ( x1.3 factor ). Hence able to reach about 520mm maximum. We can try mounting your 1.4X TC onto it, check how much the IQ degrades . That should be interesting...
I was at a camera shop yesterday evening. The shop keeper actually discourage me from getting this lens ( 100-400mm ). He claims that 70-200mm F2.8 + 1.4x TC will let you have a better coverage , cost savings, weight advantage and similiar performace.
Well, lets see how this guy perform this Saturday first.![]()
Tell you the fact, with the combination, 400mm at f5.6 + 1.4X = 520mm at f6.3 and extremely slow AF....Lets pray we have a bright day that day, or else we will be pushing our ISOs. :sweat:
Kind of agreed with the shopkeeper words.
