They said it couldn't (or some said "shouldn't") be done.
After spending an hour or so with the Sony A7Rii and 100-400GM w/TC at a local hot spot, we decided to go back at end of day.
The lighting was very good, so I thought I would try the 150-600 Sport adapted using the Metabones EF to M43 adapter.

Although the birds were so far away that the shots were not good enough for printing large, it was only because they were far away. (In other words, don't be too critical, unless you can give helpful suggestions )
In any case, the results were good enough to share and good enough to help us identify some new birds for us. Here are a couple. Remember, they are crops (as shown in comments), because even with the 1200mm FF equivalent, they were still a little too far away.
Some were sharpened and touched up in LR.
The last image shows how far away the White Pelicans were. It was taken at 560mm (Sony). (don't be too rough on that image, the lighting at that time of day was pretty bad, with definite heat wave distortion that went away when we came back later with the Olympus.)

Anyway, although the birds were still too far away for great results, it makes me want to try again with birds at realistic distances. If only the wilderness area would let us go off the trail...

All were taken with EM 1.2 using Sigma 150-600 Sport. Other metadata in the captions.

By the way, all of the waterfowl in the fourth image were located about the same place as the two black and white Grebes in the last image. When the last image was taken, there were not nearly as many waterfowl.

This gives you an idea of how much of a crop I was using (not sure why I only had the lens at 497mm?!?).

Uncropped version of the fourth image.

Looking at these images, I think you will be better off shooting with the Oly 300 PRO in DTC mode.

Sure, it's all in camera. So let's see, 600mm x 2 x 2 = 2,400!

So that means you need a series 8 tripod, right?

RE: DTC.

I did some experimenting with the Olympus 60mm macro (only because it is a little easier to experiment with in my home office).
When you use DTC the RAW file is the same as the RAW without DTC. In other words, if you take two pictures of the same subject, one with DTC off and the other with DTC on, you will end up with two identical RAW images.
DTC is only useful with JPG's and then only if you don't care to spend any time post processing, since you can do as good a job (or maybe better) taking the RAW to PS and using its engine to double the number of pixels through interpolation. I have made some really nice prints up-rezzing images bigly (:-)) in PS.

I still do plan on doing some more comparison shots, though, because there is the possibility that the 300mm w/1.4TC (840mm FF) can do as well as the 150-600mm (1200mm FF) on the EM 1.2.

Kim, you're correct about jpeg only from DTC, but using the largest LSF jpeg provides a file about as large as the raw file. You are more limited with post processing but my testing so far shows some pretty good results using DTC, of course YMMV! I find unless the conditions are poor the DTC image is as good as I could produce but with much less work for me!

FWIW I've done this successfully with both the 300f4 and my 50-200 with EC14, I tried the 14-150 but wasn't satisfied with the results.

One problem in uprezzing/interpolating a cropped image is that unless your image is in accurate focus, you are not going to end up with a good/sharp image. With the DTC on i.e. you are zooming into the image, you are more likely to end up with a critically sharp image. That's what I think anyway, and I may be wrong.

Since DTC does not work in RAW, I was wondering if using DTC as a focussing aid is a good idea i.e. instead of using the Magnifying tool. Any thoughts from anyone?

Bobby, as I recall with magnify you can go up to 14x vs only 2x with DTC. That said, I know someone who uses dtc as you described and likes it.

I have actually assigned a button for Magnify x5 but never remember to use it. . I guess I am pretty much still old-school and have not gotten used to all these gizmo features.

OK, did some more testing yesterday, late afternoon.
This post concerns only a comparison of 300Pro w/1.4TC vs. Sigma 150-600 Sport.
And, a comparison of a crop of the Sigma DTC image vs. the exact same image's RAW file taken to Photoshop and up-rezzed x2.

First image: Oly 300 Pro OOC.
Second image: Sigma 150-600S at 600 OOC
Third image: crop of Sigma image from DTC (x2) jpg
Fourth image crop of Sigma RAW up-rezzed (x2) using Photoshop

All images are OOC. Note that speed was only 1/200sec, but I used a tripod and used delayed shutters. I think that the 300Pro image may be very slightly out of focus <b>OR</> it could be that the TC is slightly affecting image quality. One of the downsides of the 300Pro is that, in my experience, manual focus is very touchy, especially when using the TC. I should have done some image using AF, but there were some leaves blowing in front of the target that were affecting AF. I will do this one more time in good light, higher shutter speed, and very careful focusing.

My take, and I am interested in yours:
1. DTC is nice if you are not using RAW images and working the images - and not so bad, even if you are, since you can still get the RAW image.
2. DTC is doing some noise reduction (as are all jpg images from the camera). Probably could do a better job working on the RAW image. I didn't have a bird subject, but it looks like it would result in somewhat pasty feathers.
3. It is easier to get focus using MF with the Sigma, because it is not so touchy.
4. The Sigma looked better than the 300Pro, even though the ISO with the Sigma ended up at 1600 vs. 640 for the 300.

That all said, I will continue to use the 300Pro since it is <b>MUCH easier</b> to use the 300Pro handheld for several reasons: Obviously lighter and smaller; MUCH easier to get to the focus ring when holding lens with one hand - it is right there where your hand is, whereas the Sigma's focus ring is way back, hard to reach with the same hand you are using to hold the lens.
<b>But,</b> I will be taking the Sigma along with me on outings where I do not go far from the car and can bring the tripod, or at least monopod, along easily.

Now if I could just get the Olympus 1.4TC to fit in the Metabones adapter!

After posting this, I went back to LR and tried to beat the DTC image's noise reduction and could only match it. I am sure the C4 experts could do a little better, but Olympus has a pretty good noise reduction engine, AFAIK. But, when not zoomed to 100%, I actually prefer the slightly grainy look of the OOC RAW vs. the slightly pasty OOC of the Oly jpg.

Just finished testing in brighter light, using AF only, and you would have a hard time telling which is the better image. Overall, looking at enough images, the Sigma might be slightly better. Maybe.

The only conclusion I could make is that the EM 1.2 is an amazing body (focuses quickly, even with the Sigma). The 300 Pro is an amazing lens, even if you don't take into account its size. The Sigma Sport is an amazing zoom, just too big and heavy for hiking, kayaking, etc. :-)

I started this testing just to see if the Sigma would work at all with the Oly. Nice to have a lens that is as sharp as the 300 Pro w/ TC that is a zoom and goes to 1200mm equiv.

Hi Kim,

I've been doing some homework on using adapted EF glass on MFT (much like I currently do on E-mount) and came upon your thread here. Thanks for posting your result images and experiences...very pertinent and informative for my wildlife/birding applications.

That you have some free time along the way I would be curious if you could elaborate a bit further as to how well the EM1.2 and the 150-600mm Sport, er, "got along" using the Metabones adapter? (I'm assuming you're using a MB IV or V?) And, in particular, how you would compare the experience vs using native glass? (i.e. camera/lens AF compatibility and full/partial camera/lens function support?)

I ask as I'm loathe to jump "whole hog" into a new system and would prefer to just beat up a body (or two) first to see if I can live with the ergonomics and functionality before committing to some native glass. (Frankly, while Sony's sensor DR and ISO performance are "much to my liking" their camera bodies—a7sII, a7R, a6300—are proving to be unsatisfactory for me on the ergonomic front and I find myself, this time in MFT land, window shopping for a "better solution"! Although...if Sony were to produce and 24MP APS-C "duck-shootin'-fast" a9-body-class camera, I'd likely "suck it in" and deal with the ergonomics. But right now the GH5, EM1 II and, soon-to-be-released Panny G9 have got my attention!)

I do love your long-distance 150-600mm Sport shots and I'd be more-than-happy to be bringing images like that home from my outings when close access doesn't permit! Thanks again for the posting!
