  • Using tele-converters

    I have a vague memory that we have in the past been told that we can't stack adapters/converters. I frequently use the EC-14 teleconverter with the 50-200mm big43 lens - and to use this combo on micro43 would require adding the adapter, which might be "against the rules". The same would apply to using extension tubes for macro.

    I've had a look through the reviews and not spotted this mentioned anywhere (which doesn't mean it's not there of course). So the question is will the combo of E-M1 - m43 to big43 adapter - EC-14 - 50-200 (or other lens):

    a) Refuse to play at all

    b) Play but with some restrictions, for example the IS not calibrating properly or autofocus being compromised

    c) Work just as well as it does on the E-5

    No prizes for guessing my preferred answer.

    Not sure about the E-M1 but I did have problems on the E-M5 with a strange rattling noise with the 300mm f2.8 and EC14 plus inaccurate AF. Inaccurate AF with 50-200 as well but not sure whether that was just down to the EC14.

      When I still had my 'long reach' FT kit, the EC14 + 70-300 worked as well (i.e. within the limitations of the lens) with the MM1 adapter and either an E-P2 or the OMD as the combination did on an E510. There doesn't seem any reason why your set-up should behave differently.

        I think it will confirm OM-D EM-1 = Converter ring + 50-200

          Re: Using tele-converters

          I use the E-M5,MMF2,EC14 and lens a lot.Mainly the 50-200Mk1 or 50mm macro.
          It seems to autofocus the same as without the Teleconveter ie a bit juddery and slow but reasonably accurately.
          I use it with manual focus most of the time.
          I can think of no reason it would not work on the new camera,but try the x2 digital converter,you don't lose any light and looks very good to me.Also one less link in the chain.

          Hope this helps.
          All the best

            Re: Using tele-converters

            Just to add some useless information to this thread... last year I hired the EC-20 from Ian and took it along to the local Red Kite feeding station. I didn't get on very well with it combined with the 50-200SWD and favoured the EC-14 for the majority of shots.
            As I was walking back to the car a thought occurred to me, I wondered what would happen if I used both!!
            One of the kites had settled in a distant tree so I set up the tripod and fixed both converters between the 50-200 and the E-620; there was no auto focus and the first shots were underexposed.
            The shot below is rubbish, and is a crop of the original, but I thought I would post it to show that you can take an image with this combo.

              Nice try Iain

              The problem is not so much whether you can squeeze a picture out of it, it is to what extent the camera functions are compromised. So for example the camera might refuse to see the converter downwind of the 43-m43 adapter, so it will not take it into account when calculating the focal length which in turn tells it how much to move the sensor for image stabilisation. Or it might affect autofocus in some unknown way. I'm quite surprised that with both converters it refused to AF at all, though!

              Like Andy (and a bit like David) I've tried the 50-200 with and without the converter on the E-M5 with the original non-weathersealed adapter and AF seems to behave equally badly with both. It makes some horrible clonking noises so I stopped trying pretty damned quick.

                I tried photographing the moon last night with the following combo
                EPL5 + 50-200 (old) + EC20 + Viltrox adapter + DTC.
                Autofocus was slow and the camera often fired before focus was achieved using a remote cable. Easier with MF focus though. Results weren't too bad and this was the first part of the test to determine whether or not I keep the EC20. The next is a test in daylight.
                Not sure how often I will need 1600mm equivalent FL but if it is anything like 800mm it will be very seldom.

                  If I'm having to use MF then my Canon EF 400 mm with an EF fit 1.4x will give me superb images at an EFL of 1120mm and even with the DTC the results are very good - only one stop light loss and none of the problems associated with a 2x TC. There are plenty of excellent 400mm primes such as Leica etc. available for less than the price of an EC20 and most of them work well with a 1.4x if it is available.
