Hi Everyone -
So I bought a Pentax 6x7 MLU and have shot a few rolls of film through it with no issues. However, all those exposures have been at 1/60th or slower. I shot half a roll today at 1/500th and 1/1,000th and got absolutely nothing - blank frames. The other half of the roll was shot at 1/60th and those exposures look fine.
Has anyone experienced this before?
Thanks in advance - Steve
