hi,
don't know where to post. so just tot newbie would be a good place. i'm a newbie in area of tcon..:bsmilie:
I can't find info anywhere off the net.. so post here for experienced tcon-ers to fill me in.
I'm thinking of getting a 2x or 1.4x tcon for my D70 with a 70-300APO. My question is.. how will the teleconvertor affect the closest focussing distance (currently at 95cm giving 1:2) image size and DOF.
eg: a 2x tc at 300mm will give equivalent of 600mm, if i use f/5.6 i will lose 2 stop of light to become f/11, correct? so.. what is the DOF now? at f/5.6 or f/11?
also if at 300mm i was able to shoot at 95cm.. using a 2x tcon to 600mm. will the focussing distance change? and.. what will the reproduction size on the size be?
:dunno: :sweat:
