Just yesterday I bought this lens and alas, today I read Michael's review. There are two things I wasn't aware when I got the lens and Michael doesn't mention them either: the close focus of 95cm is not too generous and although those rubber rings look like gears fir a follow focus, their pitch is wrong. a bit of a shame.
maybe someone will carve replacement rings, shouldn't be too difficult.
does anyone know of good quality close up tubes that cover full frame? all I found were cheap plastic one for aps-c.
