What am I doing wrong?

Why is this picture not sharper? Shooting A7 iii with 1.4 telecoverter and 70-200 2.8 gm on a monopod.

are you taking about the background?

if not the teleconverter has some impact to IQ

Camera motion in the mostly vertical direction. Try it with EFCS or silent shutter and see what happens.

you shouldn't need stabilization at 1/2000th, with a monopod, try turning it off.

 

[alex0742]

No. Just the player. All images look like this. It's not bad just not great. I guess I was expecting better.

 

[MILC man]

I agree that it should be better.

do some more testing, per the suggestions in this thread.

I have found even on the 100-400GM that with a TC you need to turn off steadyshot. No need over 1/1600 and higher anyway. I can use steadyshot just fine without the TC.

With some long Sony lenses on a7x cameras, I have seen pernicious interaction between the mechanical first curtain and the OSS/IBIS systems. That is why I recommended trying EFCS or SS.

You are correct that at 1/2000, OSS/IBIS is unlikely to help, no mater what the shutter mode.

This may be a long shot, but try switching the OSS mode to 2 (panning). Since you’re on a monopod, maybe the OSS compensating for all axises is doing more harm than good. Try also without the TC to see if that significantly improves IQ.

 

[alex0742]

I tried that and most images were with no stabilization.

 

[Zefah]

That doesn't look right at all. I use the 70 - 200 GM and 1.4x teleconverter a lot on my A9 and I've never seen anything like that. Looks like extreme camera shake on the subject, but the background looks fairly stable...

Dont use the tele-convertor you are already one stop in the hole. ISO is way too low. even in the film days you need ISO 400 for motion, so that is the bottom ISO if not a lot more

I was going to ask why you made that suggestion. I was having a similar problem last week, different lens and TC combination. I went down a different thought process as to the cause but came to the same solution. Switching to SS improved things for me. I was shooting at 800mm so I wondered at the time it was ‘shutter slap’ as apposed to good old fashioned mirror slap. An interaction between shutter and OSS/IBIS makes a lot more sense.

Are you saying that you think 1/2000 seconds is too slow!

If so, yikes!

Try the lens without TC to see on the same setting if you can get sharp photos? I have never even tried 1.4x TC on FE 70-200 GM. I heard sharpness is not great but recently I have seen someone's copy has the great sharpness with 1.4x TC.

Otherwise I always leave EFC (electronic first curtain) and IBIS on my FE 100-400 GM with or without 1.4x TC in action type photos and I got great sharpness as you can see in my airshow photos. I did such with Canon lenses in the past and the same with Sony counterparts.

Must have read it as 1/200. Basically shoot manual exposure and set your priorities

 

[Kohakoo]

I had this problem and switched both of these to AF.

Please look at this thread.

Sorry, meant to say :

Priority Set in AF-S

and

Priority Set in AF-C

Interesting Jim, good insight. Typically I use SS but it may be possible that I was using my shutter when the issue came about. I will test it out today.

 

[engbert]

I think it is mainly motion blur. Look at in Photoshop, experiment on different layers with shake reduction and smart sharpen-motion.

I don't know how you got motion blur at 1/2000th. Did you get a lot of shots like this?

 

[nopix]

Why do you have the ISO set to 100? Try 400 or 800. Lower ss to 1/1000 or so. Experiment to get the best settings for the lighting.
