Lens extenders

Re: Lens extenders
Most people think the 1.4x converter is the way to go. You'll loose one stop, but I think your AF will be OK. IQ is supposed to be OK too. The 2x will loose 2 stops - don't know if that will affect the AF. Some say the IQ suffers, but I've never used one so can't advise here.
I think GS Gary said he uses both 1.4x and 2x - and sometimes both together, so he will be able to advise further regarding IQ. |
