O75/1.8: should there be a teleconverter?

    Wondering if anyone who has the 75/1.8 is finding they are not using the long zooms any more much (P100-300, 75-300, 40-150, etc.).

    And also, did Oly miss an opportunity by not releasing a 1.4 or 2X teleconverter. The lens is certainly fast enough to make use of a TC.

    I really want to see a teleconverter for this lens and the 35-100mm f/2.8 zoom, as well as the 150mm f/2.8 coming from Panasonic. A 150mm f/2.8 & teleconverter of sufficient quality might be enough for me to give up my 100-300mm.

    Agreed!

    But nothing substantial rumored.

    Yeah... I don't think they're planning to produce one (either company, that is) soon. I'm not sure why; maybe it's a technical reason or they just don't see it as a priority, but either way I'm not holding my breath!

    I wouldn't mind having a 105mm f/2.5 and 150mm f/3.6. That wouldn't be bad at all.

    Some of the TC's I've used in the past had a protruding rear element. Maybe there's just not enough room?

    Yeah, that's what I was wondering... maybe a technical problem with creating an effective teleconverter for m4/3, but I don't know enough about design to say.

    Another possibility that occurs to me is at least with Nikon, the TC design requires a recessed rear element (which the current m4/3 lenses don't have) or it'll damage the lens. Could be that m4/3 lenses as designed are very difficult to create teleconverters for, for minimal gain - how many would they sell, compared to investing in creating a new popular lens for example.

    I'll take something minor like a 1.4 TC. That would give the 75mm just enough extra reach for me with minimal light loss!

    We were just discussing this the other day. I was about 10 rows back at a small concert and photographed the performer with the 75 1.8. Best shots were at around 1/500th sec at f/2, which stopped the performer's motion pretty well. ISO 800 yielded good results for screen viewing, with the cropped area about 1/3 of the image. I'd like to have a slightly longer fast lens, and I think a teleconverter OR a 105-135 f2 or 2.8 would be a great addition to my kit.

    Neither the Olympus EC-14 1.4x nor the EC-20 2.0x teleconverter project into the camera lens mount, nor do they project into the rear lens element of the lens mounted at their front.

    ec14.

    That said, going from 38.67 mm to 19.25 mm flange distance may make teleconverters more difficult.
     
  12. It's the other side of the teleconvertor where the issue will be. The bespoke Nikon, Canon and Sigma TCs have a protuding front element which only works with lenses that have a recessed rear element.
