Oshiro 2:1 60mm Plus x2 TC on Four Thirds: First Images

Once more, I am posting this as a separate thread, as this lens has attracted some interest.


I regularly use a teleconverter with my Olympus 4/3 50mm f2 macro and was curious to see how the Oshiro performed with one behind it. I purchased a Kenko 2x Teleplus, costing nearly half as much as the lens.


The aperture was set at f16 on the lens, giving an effective aperture of f32, where I expected diffraction blur to occur. It did and was dealt with by applying software.


All these images were hand-held and they are uncropped.


The subject was one of the smaller hoverflies and the field of view as 5mm wide (7:1 on full frame).


The lens plus TC were mounted on my EM-1 and lighting was twin TTL flash.


This setup is clearly worth further testing.


Harold

Impressive stuff Harold. It would be interesting to see what a larger aperture would do and then maybe stack some images?

Harold, it is surprisingly good.
I tried it with the mc-14 TC, an fov of 6.5mm. I am waiting for the NIK-43 converter to try it with the EC20. I also tried the mc-14 with an additional 26mm of tube and the result was poor (fov 4mm). You win the dirtiest sensor prize! I win the best use of the spot healing brush to disguise it!

Collembola and happy faces (60mm + mc-14 f11 indicated).

Thanks, Phill,

The fly was shot in numerous positions of the flower and at various angles. So it is not a tripod project! It is possible that, where support for my hands/the camera is available, sunlight stacks could be done on suitable insects or flowers. Framing and focus are very difficult for just a single frame! Then there is almost always (magnified) air movement.

Where stacking is most feasible is with fungi and slime moulds.

Thanks, John.

I have good days and not-so-good days. But I am out there almost every day and usually for at least half an hour. even so, I gets lots of rejects.

This morning I was really struggling to frame some of the smaller flies but I did get the one of which I got only the rear end the other day. A very distinctive one which I had not seen before this week. Images will appear here this month.

This thread is inspiring me to start taking macros again!

As Harold is the 'Macro King', I wonder if he, or someone else could point me to the thread where there are images of his twin flash setup, please.

Yes, there were three tiny spots on some images, but gone by the last and not there now. I am always expecting some, as I change lenses in grubby surroundings.

Sorry to cause a relapse when you were well into recovery!

You wanted to see my setup. Actually it is generic. The main flash is now an FL-36 R instead of a 50R and it doesn't have the tinfoil mask and the smaller flash is not on the straight bracket but held in my right hand. The latter is to reduce snagging on foliage and to help with flexibility of beam angle.

The lens (Vivitar 105mm macro in image) used may be an Olympus 4/3 50mm f2 or the Oshiro. It all works together. That said, here is the closest image to the current one:

Thanks.

I must try a stop wider, for better comparison with the 4/3 50mm plus x2 TC.
