The thread on how the Digital Teleconverter (DT) works made me want to try it. As a RAW imager, I would have never thought to try it and most digital zooms just don't work for me. However, I must admit the one on my EP5 must have gotten the same magic dust as the IBIS IMHO. If you've used this setting post your images here. Here are three pseudo brick wall shots for just testing, the first image is with the a raw image at 150mm, the second is a jpg with the DT on. Both images resized to 1920 full frame.

Just a couple from the 15mm body cap and dct on an E-pm2. This is my pocket outfit for outdoor use.

I use DTC as needed when shooting video and it's quite useful. Doubles the range of my 45mm and 85mm lenses.

For stills, I have concluded that I could crop the RAW and get the same image as the 2X JPG, with more latitude to fix things on the RAW if the light was marginal. However, the advantage of DTC is composition so I still use it. It would be harder for me to frame looking at the same scene, knowing I was going to crop the center portion.

I've used the digital teleconverter a few times with my 12-40. I set the button on the lens to the teleconverter function. Decent results.

What you need to do is take a crop from a normal shot and compare that with the digital zoom shot and see if there is a difference. Is the DZ enhancing things in any way, or simply cropping the image as you would in LR, PS or whatever?

Yes/ I find that the out-of-camera JPG is resampled to the same size as a regular JPG, so it is a larger picture in terms of pixels than a typical crop out of I make out of Lightroom. There are other tools which can resample the RAW though. Next, OOC JPG's from an Olympus are pretty good in good light. You have to do some work in Lightroom to get the same results from a RAW file.

In short, it is a useful tool on the 16MP EM5 and sensor because we're counting on the sensor to deliver when magnified. Less so on the 12MP sensor on an EPM1 because there's less resolution.

As Harry says you can get the same or slightly better results in LR/PS with some work. But for framing and for a lot of shots the images I think are good up to 13 x 19 prints. I use the 32/64 meg cards so I've just set my EP5 to capture both RAW/JPEG with the DC on (since it only works with JPEGS, this gives me both worlds) since I don't have any space worries.

With DTC the metering is done on the cropped part only. I did an extreme test, black background with white center, and I had one stop of difference in the exposure time (A mode, fixed iso). So it's not the same as cropping in post, even when shooting raw.

Same setup. Handheld so no guarantees about framing or distance although I did aim for minimum focus distance for both shots.

Not going to win any pullet surprises but illustrative. jpegs from an E-pm2 with 14/2.5.
