p.1 #1 · OM-1 2X Digital Teleconverter indication in EXIF or image review?
I have been playing with the 2X Digital Teleconverter (DCT?) with my OM-1, with the 40-150 F2.8 and other lens, and cannot see any indication in the EXIF data of downloaded images of the DCT being applied. The actual shooting focal length set on the lens is properly indicated in the EXIF data, even when adding the MC-14, but does not reflect the 2X magnification factor when it has been activated. The recorded image is obviously magnified accordingly per the application of the 2X DCT.
I can always hold a hand in front of the lens prior to and after employing the 2X DCT if all else fails.
Am I just missing a step--or just not seeing something-- in the camera set-up to get the EXIF data to correctly record/indicate the application of the 2X DCT, or is that just how things work and I need to develop a workaround? Thanks.

I use the DTC quite often. I'm not aware of any indication in the EXIF that the DTC was employed. However, if you shoot RAW + JPEG and load the RAW file into OM/Olympus Work Space the image will appear with the DTC crop frame shown.
Another work around, which I have not tried, would be to add an audio message to any DTC image indicating that it was captured as such.

Tony, (sorry I put this reply in the wrong place)
Thanks for the link to the instructional section available on OM System's site, as I had forgotten about it.
So far I have only experimented with the 2X DCT in JPEG mode, downloading the images in LR and viewing the EXIF data. I see the correct focal length displayed, e.g. when using the 40-150 F2.8 at 150mm setting, with the MC-14 attached without the DCT activated, the EXIF data shows a correct focal length of 210mm. Yet on those same lens/MC-14 settings to which the DCT has been applied, the EXIF data in the downloaded images indicates the same 210mm focal length. Similar inaccuracies occur with other lenses at various focal length settings.
I do see the 2X indicator visible in the upper LH corner of the viewfinder when it is active.
I think the 2C DCT can be used effectively in certain situations, and some of my images have proven that. I need to go back and do more precise testing, keeping close track on which images had the DCT activated and which did not. I was hoping the EXIF data would indicate that, but so far it has not, be that operator error or whatever. I can keep notes as I shoot to better track the results and possibly find out if I am missing a step somewhere. I can see where ORF/RAW images downloaded into OM Workspace would be more apt to indicate the use of the 2X DCT.
Thanks for the feedback and suggestions, and I will keep working with it.

Greg,
Thanks for the information. Although I shoot JPEG/RAW to Cards #1/#2, so far I have been so pleased with the JPEG's out of the OM-1 that I mostly view them and not the RAW files.
Based on your experience, maybe that is the way it is supposed to work with the reporting of the activation of the 2XDCT and JPEG data. To me, in my experience, the advantage of activating the DCT would be situational and usually spur-of-the-moment, although I can see when its planned use could be beneficial. As you say, there are work-arounds.
Anyway, thanks again for the feedback and I will keep playing with it. I was hoping the DCT would negate my need to purchase a 100-400mm, so we shall see.

Yo Steve,
I am guessing the 2XDCT does not show in the EXIF because the physical focal-length of the lens did not change.
Not sure if there is a button you could assign to indicate that those jpegs were shot with the 2XDCT.
I shoot RAW all the time, but have the 2XDCT & jpeg assigned to Custom Mode 4.
For those that say just use a 2X TC or crop in PP, I would say for posting here those would not look significantly better. In addition, with the 2X TC you lose two f-stops of light.

If you play the image you have just taken with the 2XDCT, then press the ISO button at the top right on the back of the body, it will assign a star rating to that image. That rating will show when I open that image in ACR.

Thanks a lot Tony!!,
That will work great for me. I remember watching , I think, that video from Rob Trek with all of its information, and will revisit it and learn how to apply its content. He is certainly a wealth of knowledge and I have viewed a lot of his videos.
Thanks again, and I am also learning a lot from viewing your excellent images.

Hey Tony,
You are right in the fact that the focal length does not change, and I guess the way the camera actually applies the magnification from the DCT, with it done basically in the sensor/processor or such, that the only registered focal length the EXIF data can display is what it reads from the lens and/or MC settings.
I shot a stationary Heron on the river the other day, about 50 feet--oops meters!--away with the 40-150 F2.8/MC-14 in nice bright sunlight, and the 2XDCT jpeg downloads looked decent on the monitor, yet looked a little mushy when zoomed in to 1:1 on LR. It seems I have tried a few in the past, with maybe flowers, and some came out pretty sharp and some didn't.
I don't see me using it very much, but it is/was interesting to experiment with, and you are right about losing some stops of light. I am trying to use the OM-1 more, instead of my Nikon D850, and need to learn a lot more about how to apply its capabilities.
Setting up C1 and such is a good way to "customize" it as I learn.
Thanks for the help, and I'll keep practicing and hopefully learning with help such as yours from this forum.
