i read some threads, not sure if i got this right.
using a teleconvertor, will your minimum focusing distance worsen?
doing macro, comparing closeup filter (e.g. canon 500D) with extension tube(s), will closeup filters (especially cheaper ones) cause more distortion, whereas extension tubes don't?
canon 500D sounds good but is there a cheap and reasonably nice alternative brand?
it's easier to use extension on shorter-focal-length lenses like 50 or 80mm because the enlargement is more obvious, whereas a long one like 70-200, at 200 you need lots of extension for the same enlargement?
judging exposure values with extension tubes - just use the camera's TTL meter as per normal, no special calculations necessary?
thanks ..
