Several really very nice images with that EF600 lens, congrats! :thumbup: But I can't stop wondering why you are using both a .71 adapter and 1.4 TC combined as they will cancel each other out and adding more glass (which is generally to avoid). Wouldn't it be better to just use a straight open adapter and skip the TC to get the same focal length or keep it to get even longer reach? (Excuse me if you've had this question before , couldn't find it in a quick search :) )
Hi Peha,
First the place i live where bird photographers are less aware about the process of how to aproach the fear limit of bird. I am bird watcher first then a photographer and hence i keep my limit at little back off situation and take whatever i can since i have these things. You may be right to not add the glasses more to have glitches but as you can see those clarity with the glass and output I wouldnt mind using them to get some extra reach not to crop on already 2x crop body. I do have the 1dx to use on 600 on regular basis and these were the occassional trials i keep myself doing so to have some multiplied view.

I took this one a couple of years ago and just processed it in darktable. I didn't find C-AF that reliable with the 300mm f4 pro and there were only a few keepers. I guess this was one of them

This is pretty good sharp image I would love to keep just to my test on upper side of the contrast level as the left underwing of the tern as blown out the highlights. I am sorry I took liberty to discuss the critique without asking your permission. :)

More so over in my finding that miss you are talking about is. As per my reading and experience all mirrorless uses hybrid af over the evf meaning evf is fraction of a delay then a realtime and during the BIF's if you notice when you do hit the shutter in sequence and release it the bird might have moved out of the focus zone because of 1. IS is stabilizing the frame while the bird has / had moved out of the AF zone thats a calculative logical miss frame has to happen .. 2. it is the evf refresh rate which is really slow for the fast moving subjects.

I have tried many combination to test this and eventually I am coming to a conclusion that it is the evf refresh plus IS hunting the keeper ratio.

I have also noticed that the AF speed on the olympus body even if I put it on -2 which is once locked into focus it should not hunt to the background and forground more often but it does so quickly just like +2.

considering these situation I guess we are tend to have the miss out frames during sequential shoots.

Hi Steve, I'm considering this lens. Is there a workaround you would suggest for BIF? Hopefully there's a better way if CAF is not reliable.

Thanks!

Thank you for the thoughtful critique (which I welcome) of the photo. I agree that the highlights are blown there. As for the frame misses, this wasn't a hard moving subject. It is one tern in the foreground against a green background that is far away. It should be easy for our cameras to track and follow it, the way the Sony A9 does. The Sony also has on-chip IS, yet somehow its AF is able to lock on to birds in flight even when flying a few inches from the water surface with many distractions in the foreground.

IMHO, Olympus has some work to do to get its cameras as competent with BIF as Sony when using CAF. I normally use SAF and track the birds on my own and take hundreds of frames with the hope that 1-10 will be good.

Inspired by @atomicmak to keep working on BIF shots. It's just a pigeon making a short hop... but...

All the pictures in this thread are so good, let me make a fool of myself. (That, and I really like that small punk that lords over my backyard).

Mital, I am so very glad that you join and are sharing your images with us. I have been in awe looking at all of your posts, but didn't have a chance to comment till now. Also, I agree with you about Olympus C-AF being behind competition particularly Sony and Canon. You sum up nicely about potential issue with keeper rate due to EVF refresh rate and IS. For this reason, I set my camera to prioritize frame rate over IS and always use high EVF refresh rate when taking wildlife photography.

Anyhow, looking forward for more of your terrific images.

Cheers

I have taken a demo kit for donig some good content creation although i am late on season with most migration is starting to return back and its hot summer here now started.
I am observing some points and will fine tune to get this thing work best for bif and static. Hopefully I may sum up certain situation or settings with a month testing .

Btw i have got one question since you mentioned about the evf refresh rate. does the frame rate high did any betterment ? I have tested EM 1.1, 1.2, 1.3, 1x with that option On/Off and i felt on all bodies there isnt any diff at all which I could have felt honestly in output. And my Priority is on Frame Rate over IS always on all the bodies.

Honestly, it helps but I notice better hit rate when I prioritize frame rate over IS. EVF high refresh rate helps me noticing focus confirmation (green dot) as well as where the focus box on the subject better as I track the subject. However, for a very fast moving subject such as falcon or swift, it becomes irrelevant for me.

With someone as skill as you, I am sure you will eventually find what works best for you. However, I don't think you can expect it to be as good as the like of Sony or Canon AF system as those are class leading IMHO.

I wont be comparing OLY with either Sony or Canon as they are all in a 1" sensor game which makes them at diff level too.
