I confirm version III has 7 blades...I can't remember if the 3. version has 7 aperture blades (you're the one to check with yours) but i checked my 1st and 2nd version lenses and they have 6 blade apertures.I've had version III with macro for years and have been very happy with it. Just checked ebay to see current prices for other versions with no real intention of buying another and...
I was a bit surprised to find non-macro versions seem to have 6 aperture blades? I haven't checked all the listings but is that correct? Never having owned any other version, I always assumed that they all had 7.
I find the 7 blades in my lens much more preferable (quite nice 14 point sunstars) but is that the only version with 7 blades or is that the spec for all v.III lenses?
