Re: AF not as accurate

I was out birding and this deer did not see me, yet again the Silent shutter did its magic I even had to make a tut tut sound to make it turn and look my way it was 50 ft away.

Re: AF not as accurate

After a few months of using my E-M1 II I have come to the conclusion that the AF is nowhere near as accurate as my Mk I. I have tried changing the settings as other users have recommended but I am still not getting sharp images.

Today I took over 140 shots of a Kingfisher in good light over a 15 minute period. I was really excited and couldn't wait to have a look at the results. After a quick scan through them in FastRawViewer I couldn't find a single sharp image. Of course it could be that FastRawViewer is not giving an accurate representation of the file and that they might look better when they are developed properly. However, at the moment I feel like chucking the bloody thing in the skip.

Please don't chuck..Pass it gently to me.

I am still not getting 100% accurate but sometimes, it out performs that mk1. Seriously I too am am not sure what's with this Mk2. At times it's perfect and then it can be a pain.

Re: AF not as accurate

At least the 14-54 II lens focusses nicely (& accurately) on the Mk II instead of just racking back & forth on the E-M1 (Mk I) when it struggles.

What lens was being used? Plus as others have already asked can you share an image and exif data.

Re: AF not as accurate

Hi Ron,

I'm sad to read that. May I ask what lens you are using? 50-200SWD + EC14?

Could you post some photos for us to have a look what could be wrong? If possible with some foreground/background in addition to subject.

What I found when giving 50-200SWD + EC14 a try with the E-M1 M2 the other day is that my copy seemed to require AF calibration. Ater coming home from the session I ran a test using focus chart that revealed it was front focusing quite a bit which required -3 or -4 on the telephoto end.

Ron, maybe this is worth reading (or not).
Is he being paid for this?

Re: AF not as accurate

Well I have calmed down a bit now and I have had another look at my Kingfisher shots. They are not quite as bad as I first thought.

The first thing is that FastRawViewer doesn't seem to give a very good idea of what the images actually look like. When I open them in Apple Photos or Affinity Photo they look a bit better. The second thing is that I was obviously further away from the bird than I remember and 283mm focal length is probably not quite enough.

I started off shooting with my S-AF settings but when the Kingfisher dived down to catch a fish, I switched over to my C-AF settings to get a faster shutter speed. This increased the ISO to about 800, creating more noise. I also neglected to change the AF points from five to single and I think that could account for the poor focusing.

Here are five sample shots. The first (uncropped) one gives a general impression of the size of the bird in the viewfinder. The next three are crops of S-AF files and the final one is a crop of a typical C-AF image. Hopefully, the exif data is intact.

Re: AF not as accurate

I think you will have to do a focus test with your 50-200 and EC-14 and probably calibrate your AF. If you don't have any specific test gear, then just set the camera up on a tripod and and put 3 bottles with detailed labels staggered an inch or two apart. Focus on the middle bottle and check if you have front or back focus. Try and get a good distance to the bottles if possible.

Re: AF not as accurate

Hi Ron,


I'd agree with doing a focus test, don't think you'll be too far off but could be a touch of front focus, as Tord experienced. Looking at the 2nd, 3rd and 4th shots, not sure if shutter speed caused any softness, would have been great to see those at 1/1250 or 1/1600th.

Re: AF not as accurate

As already said single point focus would certainly help. You were at 1/500 sec on a stationary object, but the branch its standing on appears to be soft as well. I assume you had is-auto enabled.

I think its just a case of being too far away. You only have a very small area to get any detail from and you are really cropping significantly to get a larger view of the bird.
