So I have a specific question that the google has not given me an answer. Not sure if anyone knows to be honest, but here it is.
Say I use manual focus point, say the best one, say the centre point. It is a bright day (ISO100 + Shutter 1/500 type lighting) so please don't discuss low light that's a whole different question.
Say I use the same lens with all of them, unfortunately I'm going budget and use the 70-300mm IS micro-USM (slower than ring).
I ask about 700D vs 60D because the autofocus is the same. I presume the focus grab using manually selected centre point in bright light is the SAME? Am I wrong?
I also compare 700D with 70D because the autofocus system might be different - is it? will the focus grab speed be faster?
(I know for a fact compared with the 600D, my 5DMk3 grabs focus in good lighting before I can focus my eyes myself, but I think shooting telephoto with a 2nd body might give an advantage of not needing to change lens mid shoot - but that's a different issue)
