Re: Canon Extenders II vs III

If you're dealing with a full frame camera one other option is to consider using a second camera (APS-H or APS-C) rather than an extender.  Canon's APS-H 1D series cameras  have approximately a 1.3x crop factor while Canon's APS-C cameras provide a 1.6x crop factor.  Used cameras using one of these crop factors can often be found for a price in the same range as the Canon extenders.  While the 1.3x crop factor is not quite equal to the 1.4x extender, it's close.  Obviously a 1.6x crop factor is even better.  Of course, these crop factors are achieved thanks to smaller-than-full-frame sensors but, If you can live with that, you can eliminate the need for the 1.4x extender and don't have to worry about AF issues and other issues that the extenders sometimes present.
