Do any of your extension tubes mate with the Oly teleconverters?

Well - my FOTGA set of extension tubes arrived today. I first tried the MC-20 in the 10mm ring, then added the 16mm ring, then the 60mm macro - no better than the lens with just the 21mm Movo extension tube, in terms of magnification. Sigh.

I tried the MC-14, but again - the added working distance yielded a smaller image on the sensor - plus the extra glass.

Perhaps this works better for other lenses - my primary interest was the 60mm macro lens. And, I think from other people's responses their results are different than mine. I conveniently had a contact package with a QR code on it - made it easy to compare magnification quickly. Most magnification was with the 21mm Movo on the 60mm lens - it filled the frame top to bottom, for a square that measures 8mm.

Two other negatives on the Fotga extension tubes - to me: 1) My set did not come with end caps - the Movo and MEIKE sets did. 2) Using just the extension tubes with the 60mm lens gave me only black - no image at all - with either ring, With the Movo set - I can use one, two, or all three and still get AF. (Note all three I only use on longer lenses).

So - apparently I have different results than others. Bottom line, no gain from getting either of the Oly TCs to join up with the 60mm macro.

And - now I have two spare sets of extension tubes. Movo, the first set I bought are still my first choice - one of the few sets that come with three sizes at a reasonable price and they work well - at least with the lenses I tried them with.
