Title: BETTER THAN MY 2X
Review: I have both the 2x and 1.4x. I just received the 1.4x today and tried it out on a cloudy day. It is not as sharp as I would like but may be better on a bright day. I would suspect it needs quite a bit of light on my 300MM f/4 lens that goes to 5.6 with the extender. My 2x has to be tripod mounted on a sunny day to get good results. At least the auto focus does work with this extender. Overall I think it will work good enough for what I intend to use it for.I am very satisfied with the 300MM prime and as I said my first photos have all been taken on a very cloudy day and I do think my results will be better on clear days.Will update after I have tested it some more.
Is the review positive or negative?
