Rained twice in the afternoon and late afternoon, the lighting condition is bad, but it didn't stop me from doing some test using manual focusing with focus peaking assist. I must say, initially it is not as easy especially when shooting at wide open aperture. In this case, I was using the DA70.
Here's the test results:
f/2.8, 1/125, ISO400
f/8.0, 1/60, ISO3200
f/2.8, 1/125, ISO500
f/2.4, 1/125, ISO800
f/3.5, 1/125, ISO1250
The colors are unretouched, just exposure adjustments and sharpening. I just love the Pentax colors...
Focus peaking is a great tool for manual focusing. Coupled with Shake Reduction (Mode 2, with live preview), it makes manual focusing a breeze once you get used to it. Suddenly all the M42/PK manual lenses become very attractive again.
