Thread: Qs on extender

    Default Qs on extender

    Can anyone share experience on using extender (ie Canon extender)? Will it actually affect any other things just simple increase in focal length. What's the downside? I have to admit that i am considering to get extender due to barget. =)
    Wish to find out is it true that 1.4x is sharper than 2x?
    What are the difference between canon extender mark II and III?

    Image quality is degraded.
    1.4x tc is usually still ok. 2x is usually quite bad.
    Mark III should be better than Mark II, but Mark II is good enough. The problem is usually not the tc but whether the lens is sharp enough to handle the tc magnification.
