    Default OM lens, adapters and Teleconverter ponderings

    OK, so I have the 350MM F2.8 OM lens, I am still debating on selling my E5 and only keeping the EM-1 in my Oly line up..

    I have the OM to 4/3rds adapter but no OM to Micro 4/3rds adapter but do have the MMF3
    no issue using 350 alone on the E5, and even had no issues I am aware of using the EC14 after the OM to 4/3rds, but not sure that doesnt mess up quality.
    I assume no problem with lens and EM1 either if I get the micro 4/3 to OM adapter, but if I dont get one of those I need the om to 4/3rds added before MMF3 this is quite a bit of space added from sensor..
    in effect I think it would cause me to use even less of the center of the lens?

    if I add the EC14 then that goes after the om to 4/3rds adapter so that adds a space between the EC14 and lens and then space between ec14 and sensor with the mmf3 added on! Not sure I even tried this yet!

    I am thinking maybe I would be better off if I got the old OM 14x-A and attach directly to the lens then just get the OM to micro adapter to use on EM1?

    Otherwise I would need to buy the micro 1.4x to get the 4/3rds part out of the equation, and since I dont think I am going to have any lenses capable of using it, unless I get the 300 F4 and it is capable..
    and would the micro 1.4x go on body then attach OM to m 4/3rds to the TC? is that even possible?

    all kinds of possibilities, I am looking for what one would be best, maybe I am only one in this situation

    I guess I will play with it as is, if I buy the OM to micro 4/3rds adapter I would have no way to use EC14, and if I am carrying this thing around I want it for over 500MM.

    I guess my concern mainly is because I am now debating on selling my E5 while they are still getting a decent return, and I already picked up a Nikon and a Canon for my birding now
    but I sometimes like to use this 350 and ec14 for tripod shooting while I hand hold the other body in case a BIF comes by

    Or maybe I should just sell the 350MM, while they seem to be holding their value, but I did just order an OM to EOS mount to try it on the 7D to see how it does, again if I need an TC the openly way is with an OM TC for that
    Nikon only has an OM adapter that requires removing the OM mount and installing the nikon mount in its place and I am not going to even think about doing that
    the old OM 1.4 TC is probably not as good as the EC!4?

    You should be able to use the OM-4/3 adapter between the lens anf the MMF3, with or without the EC-14. Shouldn't make any difference. If it works on the E-5 it will work on the E-M1. I have done it with Nikon lenses: lens->adapter->EC-14->MMF3->E-M1.

    Yeah I have done it also, just wondered if it does anything to IQ, it would seem the farther away the last element is form senosr the more cropping effect it would have.. Funny Olypmus does not recommend using the OM 2X converter on the 350 F2.8 saying it is not compatable.. But I wonder if that was an issue with AF more than IQ as I have used teh EC20 with it no problems, The OM 1.4X-A cost more used than a new EC14! but the 2x-A can be had for 50 bucks.. I was hoping I could just pcik up a cheap 1.4x and leave it on the lens, then just need to use the OM to M4/3rds adapter which I just ordered, I have no way to use a TC with that setup unless I get a micro 4/rds TC.. but that again adds that gap.

    What I should do is just sell the 350MM that has actually increased in value from what I paid for it, but its such a beutiful lens its harder than putting my 150 up for sale was. that being said I hardly use it unless I have a good place not far from car to set it up on the gimbal

    Whatever the adapter combination, the flange to sensor distance must be identical for the lens to focus, that's what the MMF3 would be doing in this instance--filling the difference between the two formats. Rather than that path I'd opt for a straight OM-4/3 adapter and not stack the MMF3 with the OM-4/3 adapter. Each connection introduces an added chance for misalignment and play, and one supposes costs strength.

    Have yet to see any reports on cobbling the mC14 onto a lens it's not designed for, so its adequacy for the task is still speculation. An adapter in front gives cleanance for that exposed front element, making it at least possible, nobody knows whether it would be the correct distance or how well it might work.

    My hunch is you'll be best served by the OM teleconverter on your OM lens, but that's mere speculation. I do know the E-M1 gets more from the SHG lenses than the E-5 can, including with the EC14, it might also with that 350.

    Cheers,

    Rick

    A New Year with Good News (for all of us having 4/3-lenses and OM-fit lenses)!

    I just fiddled around a little with my E-M1 and the various adapters and teleconverters that I have at hand here and I found out three nice things:


    1. The new m.Zuiko MC-14 teleconverter can be stacked with the Lumix DMW-MA1 micro-4/3 --> 4/3 adapter. (The Olympus MMF-3 adapter can not be mounted on the MC-14 at all.)
    2. 4/3-lenses maintain almost all their functionality when mounted on the MC-14+DMW-MA1 combo. (S-AF in magnified mode seems to not work though.)
    3. Here is the best of all: the MC-14+DMW-MA1 combo also allows for stacking any of the two 4/3 teleconverters (ZD EC-14 or ZD EC-20) with maintained 4/3 lens functionality - even the correct aperture and focal length is shown in the EVF. (In the 4/3 system it is not possible to stack two ZD teleconverters.)


    I have not yet had the opportunity to check IQ but I expect that the m.Zuiko MC-14 + ZD EC-14 will be on par or better than one EC-20 (two stacked EC-14 are better than one EC-20).

    Cheers, Jens.

    PS. I would go for either a ZD EC-14 (or an m.Zuiko MC-14) instead of an OM 1.4x A. I bet the IQ of any of gthose are better on a tiny 16 MP sensor.

    Interesting info thanks, I dont have a mc-14 yet and probably wont unless I end up getting the 300MM f4

    I got the impression that you want to use the OMZ 350/2.8 with your E-M1 and considered buying an OM 1.4x-A teleconverter to accompany the lens. Unless you just want the OM TC in order to have the original components togeter, my take is that it is not worth the money.

    You can just as well use your existing EC-14 with a high quality 4/3 --> OM-adapter on your E-3/5 - add a high quality micro-4/3 --> 4/3 and you can use it just as well with your E-M1 with no loss of IQ.
