Originally posted by cesarfishman I bought the 55 and the vignetting on FF is bad. Unusable in infinity focus between 1.4 - 3.5.
According to Photozone, it vignettes *less* wide open than the FA 50 or FA 31.
As for real world results, if a judge found me guilty of LBA and sentenced me to a future of just one lens with the K-1, it'd be the DA*55:
I applaud the release of this D FA* 50, though. It is a different kind of lens, bigger and more expensive.
I hope it has lots of buyers.
And that there will continue to be available for full framers new or secondhand the FA50, the DA50 f1.8, the D FA 50 f2.8 Macro, the DA*55 and legacy glass going back to the A 50 f1.2. The K mount system is a rich one.
