Thanks. I read the article. It was a full and thorough review of the 150-400 and the Bird AF in the X. Mathieu does a good job with reviews.

Yeah, it’s extremely disappointing. I do trust Mathieu’s reviews, but it is interesting that others have suggested better results. I still haven’t downloaded the firmware, nor have any opportunity to do any birding to test myself, but I was hoping for some sort of improvement. I do think that there could be a difference in familiarity and success rate between reviewers who solely use one system versus those who use and test many. But even then, I would think that the bird AF would have been more of a help, unless he was somehow fighting the process – which is something I have heard other photographers discuss when advising people on how to use Olympus bird AF.A long video, but a good one. I enjoy his reviews. I am surprised though to see his keeper rate of sharp images was worse with bird AF turned on than when left off. That’s unfortunate.
But is the two keeper rate scores really from the one and same Oly 150-400 test?Yeah, it’s extremely disappointing.

In the comments, Mathieu mused that maybe Olympus needs a new sensor in order to improve AF further. I suppose that’s possible. It is the oldest thing in the E-M1X, and could be what’s holding it back. There are times when I get 100% hit rate with normal AF, so it could be the conditions and how the sensor is able to resolve them.
On more positive notes…
His findings on the highlight and shadow recovery, even with the R5, were very interesting. I’m sure a lot of full frame fans would not have anticipated that!
One thing that Mathieu didn’t mention in his comparison, but that I think must be discussed when talking about Olympus Bird photography, is Pro Capture. I think it is a extremely heavy advantage for Olympus that definitely distinguishes the system and its viability as a choice for wildlife photographers. It’s really that, coupled with the flexibility and image quality of a extremely sharp and bright zoom, and it’s portability (which he did laude) that I think really is this combinations strength.
Very true. It’s hard to get consistent enough results with tests like these.But is the two keeper rate scores really from the one and same Oly 150-400 test?
I would think the keeper rate score for the 5×5 grid is from the earlier test he did with the 300mm f4 prime?
Does not feel so likely that he manages to get exactly the same points/score every time he test the AF performance as it is not a test where you have controlled conditions and movement patterns so it is the same at every test occasion,
Agree, he show that the way smaller and older m43 sensor holds up really good when compared to to a modern FF sensor.
The lens itself seems to really good
I haven't seen any other reviewers actually make any methodical comparison though. most of the other reviews are just "It works great!" without any type of detailed comparison. I've had some critiques of Mathieu's methodology in the past, but he's made improvements and I think his recent results are all pretty trustworthy.Yeah, it’s extremely disappointing.

True but if hes going to compare 5x5 grid to bird AF he needs to do the comparison head to head same day and with same lens.I haven't seen any other reviewers actually make any methodical comparison though. most of the other reviews are just "It works great!" without any type of detailed comparison.

It’s really hard to say. I think being able to distinguish a 5% change in performance with such uncontrollable test scenarios is pretty suspect. Nevertheless, tests like these should still be good enough to give a rough ballpark of performance. I was hoping for an improvement large enough to see, and it is definitely disappointing that we didn’t get it.I haven't seen any other reviewers actually make any methodical comparison though. most of the other reviews are just "It works great!" without any type of detailed comparison.

Fascinating read, many thanks for posting the link!Two part interview on the 150-400mm

Pass.U.K. camera shops are expecting this lens to be available for sale in Spring 2021. Preorders taken, first come, first served.
Honestly, not any better than my 300/4Someone posted some initial photos from their new lens. Hopefully they open their Flicker account so that we can see the full size images but my initial impression is that this is the best out of focus results I have seen from any Olympus Telephoto to date. The Shorebird sitting on a the rock would not provide as nice out of focus blur from my 300mm f4.

Many of them were shot at 700mm. Thats 400mm + the built in TC and the MC14. And the level of detail is outstanding. Bokeh isn't that great, but the color and detail is on a level above the 300mm f4 pro IMHO.Honestly, not any better than my 300/4
Hmm... Not bad. Maybe I should buy one after all. It's not like it costed ~2x what we paid for our car 10 years ago... Or did it?
