  • 5 Frames a Second C-AF Test

    For those interested and going on from my "E-1 Action Shots And A Surprising Observation" thread, I have now using the E-30 put it to the test.

    And can unequivocally say that leaving IS on when using C-AF is detrimental to the predictive focusing.

    I used exactly the same settings on the E-30 as I used with the E-1 yesterday

    My hit rate went up considerably with 70% being usable and although they were not as bitingly sharp as the E-1 images I put this down to the frame rate of the E-1 being only 3 frames a second compared to the E-30's 5 frames a second.

    This is a sequence of five frames of Gabe running full tilt towards the camera.







    A big improvement ove what I was getting with the IS left switched on.

    Since you posted your E-30 results in this thread, I figured I should reply over here instead of the E-1 thread.

    Per your advice I checked my E-30 this morning and the Continuous AF mode is already set to release priority. Still, there is no way with the 50-200 I could capture 5 consecutive frames in 1.5 seconds with a dog (big or small ) running at me like that. Plus every one of yours is sharp and lovely! There must be something with the lens because I have never been able to get more than 1 or 2 frames in that scenario and they are inevitably blurry.

    It's raining here today so I may play with the E-1 50-200 a bit. Although the misses may not let me or the wet dog back in the house

    Out of curiosity, what are your focus points? All points, center weighted or spot?

      To me the E-30 images look much better regarding gradation and white balance than the E-1. Ok, it is not side-by-side so I reserve some judgement. But that is in line with the experience I have when comparing my ageing E-300 (contemporary to your E-1) to my E-P1 (slightly newer than your E-30). Which converter did you use? In camera JPEG? My observations are based on Apple's aperture.

      Considering the sharpness, please keep in mind the E-30 offers a way higher pixel count. Are you looking at per pixel sharpness - in which case you might want to down-sample you E-30 files to 5 MP. Also the E-30 has many more AF points than the E-30. Did you select one of these points? If not, that might help further.

      And before I forget - the last picture with your dog in full fly is just great
      enjoy

          Thank you and all images were shot in raw and processed in LR4

          It's subjective, but I would disagree with you about gradation and WB also the E-300 was more similar to the E-500 (which I also owned) than the E-1. My comment on sharpness is just down to the C-AF on the E-1 nailing focus just that fraction better.

          Just a screen grab, E-1 on the left and E-30 on the right, Gabe is black but to my eye the E-30 WB has a tint of purple in the coat and the tone in the coat look fine to me on the E-1 pic.



          Thank you John.

            I think this should be in the E-30 board - so am moving it now

            Great shots, Paul!
