In Topic: Electronic control of focus range in Olympus cameras

21 August 2015 - 05:44 AM

This post and my recent comments about autofocus issues are obviously related, as this control of the focusing range could only help improving AF performance.
But it seems i am the only one interested?
Could at least someone advise why the idea isn't relevant?
Do some of you manually limit the focusing range on the lens prior to going diving?

In Topic: Thoughts on the OM-D E-M5 Mark II or the upcoming Panasonic's?

Some focus issues i had encountered where either in silky water that the camera would focus on particles, or that it wouldn't "consider" a very thin subject, such as a pipefish. This actually occured last week to me: trying to shoot a thin pipefish with the 60mm macro: i put the focus point on the pipefish's head (meaning that small square right on the head), and it took me 4-5 attemps before getti g focus right. This was in bright light (shallow), i believe the issue was my focusing "square" was larger than the fish itself!

In Topic: Shooting schools of barracudas

Thanks both. I am now back home and had no opportunity to shoot the barras with macro/mid-range zoom, but i do have some barras at home (bit more rare though), so i can try this advice here.
I will post some barras pics here after the sorting!
Cheers

thanks all for the great advice!

@Chris & Tim, #3 and #4 are very inspiring, i'll definitely try to benefit from natural lighting as much as possible. And yes, kiss of flash rather than full blast against a dark background seem more appropriate.

@Interceptor121, i am definitely aiming for strobes indeed, it feels like something is missing otherwise. I like your barracuda shot, indeed the front ones aren't overexposed, and the next ones are gradually less exposed, and the gradation is not disturbing (since they're well aligned).

In Topic: which setup to shoot burst underwater?

12 August 2015 - 10:21 PM

Thanks for the comments guys.
@Stewart, i guess 5 fps would be the maximum i would be looking at, good to know the YS-D1 coule handle it with the settings you mentioned.

Interesting comment on the eletrical to optical converter, i think Nauticam also produce some.

In tropical water with lots of sunlight the challenge is not having too little light but too much light. Boosting ISO affects strobe and sunlight the same and needs to be compensated by closing the aperture to avoid overexposure. So it doesn't really help. Best to use the shortest possible shutter time because that cuts down sunlight allowing you to open the aperture and capture your precious strobe output more efficiently. Of course if you are relatively shallow natural light with/without magic filter will solve the problem.

Indeed Bart i've experienced it yesterday when the background became waaaay too clear behind my barracudas...
