    Thought I'd start a separate thread for this.

    I recently got an E-M1 to replace the stolen E-M5 kit (E-M5, 12-35, 45/1.8 and 100-300 stolen), and I've found a good deal on a 50-200 SWD (not much more than most non-SWD versions are going for around here these days) which will take the place of the 100-300. I don't shoot tele all that often, but when I do I'm find with carrying around a little more weight for the quality. I'm looking around to find a (second-hand) teleconverter to match. My gut feeling is that the 1.4 will give me better quality, will be more likely to yield acceptable AF speeds on the E-M1 (and 280mm is plenty), but I was wondering about any experiences people had with image quality and handling on the E-M1 with 43 HG/SHG glass and either of the converters, in terms of both image quality and AF speed/handling.

    I have both EC14 and EC20 as well as HG and some SHG 43 glass.....

    what most people struggle to appreciate is that they multiply everything, including weaknesses!

    the 2x works well with the 50/2, 150/2 90-250/2.8 and 300/2 (from use not ownership and the experiences of others)

    in good light it will deliver on the 35-100/2 and 50-200 but the latter is marginal IMO, but the 1.4 is excellent. some of the results issues are related to the use of any 400/7.1 lens, and in practice it's hard to seperate these out in normal user testing, but over the years many have commented that they end up with better results using the 1.4 and cropping than the 2.0 at the long end of the 50-200.

    I don't see a huge difference in S-AF use on the latter E bodies and the E-M1 except that the 35-100 seems to focus better in lower light situations with the teleconvertors than it did on the E's - no idea why.

    both are excellent in themselves, and there are certainly some strange pricing situations on them at the moment! In the same way as the FL50R I expect them to go back up in a few months time as people realise they too have a (long) future life :)

    handling is entirely subjective - E-M1 + grip handles 35-100 + ec20 fine, although not quite as easily as E5+grip for most.

    I use the EC20 mostly on my 150/2.0 because the result is still a relatively fast 300/4.0. As photo-owl mentioned, the EC20 + 50-200 works well only if there's plenty of light at the tele-end, because it becomes a 400/7.0. I would highly recommend the EC14 on the 50-200 though. There is minimal loss of IQ when the EC14 is used, and it remains an acceptable f/4.9 at the tele-end. I also find no loss in AF speed when the EC14 is used on the 50-200SWD and E-M1 combo. Cannot comment on the AF speed of the EC20 on the 50-200 though, since I haven't used this combo often. I did use it on shooting the moon, but switched to MF instead... On the other hand, AF speed is pretty much the same with or without the EC20 on my 150/2.0...

    Thanks for these comments as I have struck out & bought an EC20 (used) & hope I haven't wasted my money. I already had the EC14 & only bought the 50-200 SWD last year to use on my E-M1 (I would have liked to have had it when using my E-30). Anyhow, I guess I will find out & I don't expect to be using the EC20 as much as the EC14 with that lens. The EC20 might prove nice with the Sigma 150 f2.8 macro lens though.

    Thanks mate. Yes, I did revive this thread since I was crazy enough to think the EC20 (bought a nice clean boxed one from Japan) might help me on the 50-200 (SWD) lens. For the most part I will stick to just using the EC14 on it, however, I have also tried the EC20 on my Sigma 150 macro lens & that looks promising since macro shots need to be stopped down to some extent anyhow. Anyhow, I need to go & do some real work to pay for my folly now. :rolleyes:

    Mattia, I shoot the EC20 w/ the ZD300 f2.8 some but have not owned the ZD50-200 though I've thought about it. I'd add a couple things to what others have said. AF will likely be slower & struggle more w/ the EC20 than EC14 or no TC. If you get the Focus Tune set up to micro adjust, I suggest you get the long ruler kit so you can micro calibrate at something like wildlife distances if that's what you plan to use it for. For the ZD300 calibration at close distance required for the short ruler was not too good at longer distances. And focus breathing could be a bigger problem w/ the zoom so calibrating at shooting distances might be more helpful. Lastly, I've seen several comparisons that clearly demonstrate sample variation of the 50-200mm. Some are super sharp, some less so. Of course any softness will be magnified by the EC20. Last but not least, some copies of ECs & 43-m43 adapters can loose electrical connections to the camera intermittently. My EC20+MMF3 does but not my EC14.

    I have tried out my lens combo of EC20 & 50-200 SWD lens & now I am fairly satisfied having added the EC20 to my kit. Here are a few photos from today all at 400mm (with Auto ISO high limit set to 6400) all out of camera & only resized & sharpened in OV3 (for web display).
    M2123078-s.

    With bounced flash indoors.
    M2123093-s.

    M2123095-s.
    M2123099-s.

    A couple of Bower Birds
    M2123156-s.

    And a close crop to show what this lens combination can do (not the high ISO noise & smearing though).
    M2123156-scr.

    A Crimson Rosella
    M2123174-s.

    M2123195-s.

    I'm pretty happy with what I can get with this lens combination but I will only use the EC20 for reach & stick with the EC14 most of the time (unless I am working close & then I'll use just the lens only).

    I thought I'd point my 50-200 & EC20 at the moon tonight plus to save on cropping as the camera does a nice job for its JPEG output with the DTC I had that ON too with the following result (full resized image at 1200 X 900 in my Four Thirds User Gallery). This was hand held but leaning against a post for support.
