both are 49mm, but I also can supply some step rings unless they sell on ebay...
Email me offers on my linked email on my name prefer Paypal and continental 48 US.
1.5X tele and 0.8X wide converters on the D7 and A series a nice set to have, if I remember vignette stopped on the tele at about 120mm or so to give the 120-200 a 180-300 capability, and on the wide side could get the 28mm to 24mm if I remember as there was a slight vignette that may have been able to be removed with processing so maybe it could give 22.4mm.
I could not find the box for the A-200 and do not have box/paperwork or soft case for the A-28 all have front and rear caps and in great condition.
I also have a C-180 1.7X 52mm, but smaller glass opening on rear so vignette occurs on many...might not on a Minolta Z3- I have the adapter tube if anyone needs it...
