Thanks Douglas.
That FE lens has two OSS settings, one for panning, if I understood correctly.
Would that help for this situation or is the camera simply too slow?

K-H.


Hi Karl-Hans, in the situation I described, I don't think it has anything to do with the setting of the OSS. It's just the nature of EVF (maybe except the a9), what you see in the EVF is not exactly what's happening at the moment, there is a slight delay, however slight it may be. The a6500 is pretty good in that regard but to my limited use of the a6500 at the airshow, the delay is still there. For formation shots or slow (relatively) flying planes, that's perfectly fine, but if the jets are flying really fast and you want to have closeup shots instead shooting at the wider end and crop later, the chance of the jet is ready out of the frame when you still see it in the frame is higher than that with OVF.

Thanks Douglss.
I have noticed that my A9 is in a different league than my A7r.2 or a6300
with regards to focusing speed or lag.
In this regard I don't notice any difference whether I use my Sony A9 or my Nikon D800E.
And the A9 is blackout free.

Has anyone else noticed a slight amount of focus creep when using manual focus?

Background:
I spent many hours before the eclipse testing combinations of lenses and bodies, focusing on the sun's surface disturbances to get the best combination of ease of focusing and sharpness. The bodies were: A7Rii, A6300 and Olympus EM1-2 and the lenses were 100-400GM w/ 1.4TC and Sigma 150-600S for the Sonys and Olympus 300 Pro and the Sigma on the Olympus.
End results were very close, but I found that the 100-400 w/TC on the A6300 gave me the best results pretty much tied with the Sigma on the A7Rii, but easier to get perfect focus. The Oly lens and body were also very close, but the Oly lens' focusing was too touchy.

Procedure:
I had two tripods, one with the A7Rii/Sigma and the other with the A6300/100-400.
I intended to take a series of partial eclipse shots with the A7 and the full eclipse with the other. With lots of bracketing.

Problem:
During the whole eclipse, the Sigma stayed focused as I had set it, and there was enough time to use the other combo for backup shots of the partial phase. During the full eclipse, there was enough time to use both and still observe the amazing sight.
Throughout the whole eclipse I occasionally turned body power off and on.
During Post, I found that the 100-400 full eclipse images are very slightly out of focus and the Sigma images are as good or better.
The good news is that I ended up with some neat photos, but I learned that I should recheck focus regularly. Probably obvious, but in the past when I did star trails with an intervalometer, I never worried about refocusing between shots.

Please note that this could have been caused by user error. It was very difficult getting perfect focus in the shooting conditions. And, we are talking real pixel peeping. The results were great, I was just looking to get some real details of the red flares.

Thanks Kim.
Did the FE 100-400 keep the chosen focal length?
I assume you chose the stiff resistance when changing the focal length of the lens.

K-H,
Yes. The resistance works well on this one.

To all:
Just went back and reviewed them again and went back to my test photos.
As I mentioned, the problem was very slight and could be something to do with jostling when I removed the filter or turning the camera off for a while towards the last 15 minutes or so of the partial phase to make sure I had plenty of battery for all the bracket shots..
The partial eclipse photos I took early on, show the A6300/100-400 combo to be sharper than the A7Rii/Sigma combo (barely).

Here are the test shots I took a couple of days earlier.100%, no Post editing.
I'll follow this up with a crop of the Full Eclipse shots.

Here are the subject shots.
Don't laugh, they DO look very similar, but I was expecting the A6300/100-400 combo to be slightly better and it ended up being (VERY) slightly worse.

I would be surprised if it was from jostling while removing the filter, but you never know.

By the way, it was great fun and I am very happy about the whole experience, just wondered if anyone has noticed any slight focus creep during power sequencing. I know some electronic focusing cameras can do this. The first one is the A6300/100-400 and the second is the A7Rii/Sigma 150-600S.
Also, my first experiences with BIF have been limited, but positive. And, my experiences with doing close, macro type shots has been very positive.

One other note, I found during testing, that with any tele, you can get almost the same results by cropping the A7Rii as you can with the A6300, but with the bonus of added dynamic range.

Hey great shot! I'm curious to see the raw of this file. if never u shot it in raw. I'm still not convinced about the TC 1.4x that i owned but returned. I'm curious to see if it was my copy faulty.

Upon inspection it is only 24+ mb, so, I can email it to you if that will work.

Got mine this late afternoon. It is perfectly centered, and the first shots in my backyard are very promising.
I am used to shoot only the small and light Loxias, so this one is a hell of a massive lens for me.
Not sure yet if I'm going to keep it, it is really massive and heavy.
This is our local church, half a kilometer away @400mm f/5.6. It's really very sharp and CAs are hard to find.

It is certainly the biggest and heaviest lens I have. Still it is sharp and I think will be very versatile, especially since I have never shot with anything this long before. Even doubles as a quasi-macro lens, from tonight in the garden. 400mm at f5.6

Well, I'm very impressed with the lens and how well it works with both my a9 and a6300...Shot the moon last night hand held with the a6300. Last time I shot the moon was with my 1DmkIV/150-600 Sport combo (definitely not handheld) that setup weighs 9lbs. The a6300/100-400 combo is 2.5 Lbs...Fricken amazing, besides the weight and the ability to hand hold with ease the IQ is better in every way.

A quick moon at 400mm at f/8. This is a 100 percent crop, I think I need a 1.4x TC now.
