I am considering an FM3a purchase. Is the shutter in the 3a any different than that which is in the FE2 or FM2n? I had read somewhere that the top speed on the FM2n was closer to 1/2750, rather than 1/4000. I welcome any comments on the shutter. Does the MD-11 work on the 3a? I prefer the ruggedness of the MD-11 over the MD-12. I once cracked the top of the an MD-12 grip with what I thought was a more or less slight knock. I once had an FE2, and I am still considering getting one back, as the FM3a is about double the price. My main motivation here is to obtain the 1/4000 top speed, as my F3 tops out at 1/2000. The 1/4000 would be useful for blurring the background on bright days.
