If you are in S, the front dial controls SS on my OM-1. And the back well does Exposure Comp. Since as a wildlife shooter I am in S pretty much all the time. Lens is always on max aperture as there is never enough light.

Thank you dear Emilie for the tip ! I have been searching for that setting and couldn't find it.

Been using back button focus since 2007 when I bought my first dSLR the Canon 30D

Thank you Emily. I use the BBF coupled with C-AF mode all the time. A short touch on BBF works like S-AF mode and a continuous touch tracks the moving subject. I practise wildlife photography on the prowl or on beating hunt. Focusing in dense wooded field is not easy. When the animal moves through vegetation, the focus is often on the vegetation and the animal is out of focus. In this cas, the animal tracking function does not detect the subject. In open Field, no problem. In manual focus mode, the action speed does not allow precise adjustment with a 40-150 zoom lens. (variable distance, AF ring sensitivity). I'm always looking for improvements. Love your gloves too.

I understand the logic, but I don’t use back button focus for high speed bird-in-flight photography, which to me seems counterintuitive. (I do use BBF in other custom modes, however.)

Thanks Emilie. My hand mobility is compromised so back button doesn't work for me but, I always enjoy hearing about different camera setups.

I always used the front dial for shutter speed, probably because my old camera only had 1 dial.😂 Using an Olympus for the first time I didn't like the dial settings and changed it.

I've always used the front dial for shutter speed and the rear dial for aperture when in Manual mode (with or with out back button focusing) particularly with long and/or slow lenses where I generally have the aperture wide open.

hi Emilie

Thank you, Emilie. I use BBF for bird photography (thanks to you & Lee!), and since I rarely change my aperture in that situation, I have my front dial for shutter speed, and my rear dial for ISO. As with BBF, it took some getting used to, but I like it now. Always appreciate your tips!

Thanks for this tip. I’ve been often conflicted with the issue of BBF and changing shutter speed while shooting bird in flight….not remembering that the OM-1 is capable of such awesome customization 😊.

All this would be easily resolved if OM would put an aperture ring on the lense. The front dial could be SS and the back dial exposure compensation. This make perfect sense.

Danke Emily, ich verwende lieber auf der vorderen Taste die Belichtungskorrektur und auf der hinteren Taste die Verschlusszeit. Ich benutze auch BBF. Bei Vögeln im Flug kann ich so viel schneller eingreifen, wenn der Vogel am Himmel zu hell oder dunkel ist.

Thank you Emilie, super useful advice!

Thank you, Emily. I changed my setting to use the BBF because Tato and Marta (from Indomitus and previous OM-System ambassadors) told me that it was a must for astro photography. I easy got used to it. I think that for macro it is also a must (and for every thing).

That made a lot of sense to me because I should dial in the shutter speed based on the action more. I have a manual lens for macro so apeture is always set on the lens.

Great info especially for older cameras & DSLR. I read an article that with the new mirrorless & whole frame wide coverage AF systems that the author was using the Shutter for the AF because of the wide frame AF coverage 7 felt no need for the BBF anymore. I'm still using a DSLR but it made sense as I read it. I'm sure a lot of mirrorless users are still using BBF & the way you have set up yours makes the most sense. Now I have to see if my camera offers this change dial option. Great tip, thank you for the vid.

Haha, I always shoot birds in flight in aperture priority mode! 😃 Before I got my Olympus 300/2.8 I used an old manual focus Nikon 500/4 (sometimes using a speedbooster to get a 350/2.8) and I think I used aperture priority even with that lens. I guess I think the camera is better than me at choosing a shutter speed that gives a decent exposure. 🙂

Thank you, Emily, very interesting and as you say it makes sense.😎

changed! CHECK👍
