In Topic: Rokinon 7.5mm MFT on EPL5 sweet spot and focus

08 August 2014 - 06:28 PM

If I look at this at 100%, focus is not that good.

 

I shot this with focus fixed at 0.5ft  (or 0.15m).  Give the DOF scale, I'm now wondering if this wouldn't have been better at something closer to 0.8ft (0.24m)...

 

Strobes are a bit hot too...  so I think I should have maybe shot it at 160th sec. (or have set the camera's EV to maybe -0.3)?

 

PS - really kinda amazing (to me anyway) that the YS-350s work so well with this (thanks to the H/W Digital Adapter).  I only had 2 misfires all day and by setting the Olympus EPL5 to "use" RC (Remote Control ON) and the YS-350s to TTL, I had  a fair bit of success (at least after I set the ISO to 200 down from 400, and increased the Shutter to 1/125th)

Here is a sample of today out at Pickles. Bad storms last night had things stirred up a good bit, so water quality wasn't the best...

The more I think about the testing (which was all "fresh" water - not salt), the more i'm leaning toward setting the focus ring to 0.5ft, as the change in diffraction due to density ought to cause the focus to shift closer...


FYI...

 

Here is a sample (cropped) shot from the pool test...
