How To Use Olympus Extention Tube Ex 25 On Four Thirds Cameras
EM1, extension tubes, and 4/3 lenses
I do a lot of macrophotography, and I've e'er felt a bit at a disadvantage with my E5 compared to Canikon shooters. For one affair the only 4/iii-arrangement extension tube that preserves focusing ability and f-stop control is the EX25 (at least I was unaware of any on the market upwardly to a year or so ago). For some other thing, Olympus doesn't let yous stack accessories, similar using the EX25 along with the EC14 or EC20.
With the advent of the EM1, things have improved for 4/iii macro photographers. Even leaving bated the IQ improvement and availability of the M.Zuiko 60mm f/2.8 macro lens.
Offset, there are third party m4/3 extension tubes that preserve the communication between body and lens.
For example, the Meike ready (10mm + 16mm) that I only bought via Amazon. So at present you tin can use extension tubes with the longer focal lengths of your midrange zoom lens; perchance that would be useful for saving weight when you travel.
Southwardecond, if you put the extension tubes between the EM1 and the MMF3 adaptor, yous tin still put an EX25, EC14, or EC20 between the MMF3 and your four/3 lens.
For example, I now can get 51mm of extension with my Sigma 150mm f/2.8 macro lens past adding the EX25, maintaining focusing ability and f-stop control; my magnification is now close to the predicted 3:one (or 6:1 in full-frame 35mm terms). That's a field of view of a little over 7mm, measured diagonally.
Since a stack of two m4/3 extension tubes works, I speculate that I could buy another set and put all four together.
Adding an EC14 or EC20 to the m4/3 extension tubes doesn't seem to ever give every bit peachy an increase in magnification as I would have predicted (at least on the Zuiko 50mm f/2.0 macro lens), but the system basically works OK.
Incidentally, trying to stack the EC14 and EC20 all the same doesn't piece of work. Nor does the EX25 and EX14 combination. I presume the EX25 and EC20 can't exist stacked either, but I oasis't tried that.
In that location are mechanical concerns when yous accept such a long stack of adapters that include lightweight extension tubes, particularly with a heavy lens like the 150mm. It doesn't seem and so bad for the 50mm lens.
Anyhow I think there's some interesting new territory for Oly 4/iii arrangement macro photographers to explore here. And I'1000 less envious of owners of that wonderful MP-Due east 65 macro lens, which brings so many bug photographers to Catechism.

How much more than can your main lenses take - are they still holding upwards sharp with TC and macro rings... do you call up they could opticly handel another 2x TC or another 16mm of rings?

I simply discovered all this today, and then I oasis't really dug very deeply into the IQ issues. I'm pretty busy now simply promise to take some results inside the adjacent week or so.

Re: EM1, extension tubes, and 4/3 lenses
I like doing macro piece of work.
The Olympus 35mm Macro and 50mm Macro are excellent lenses for all around utilise. For more dedicated macro-close upward piece of work, I fit a mount adapter and have used Micro-Nikkor 55/3.5, 105/two.8, and 200/4 lenses. Since these are used entirely manually, you tin fit inexpensive, goose egg-electronics extension tubes and another other enhancements (teleconverters and such). I've sold the setup now, but the Micro-Nikkor 200mm f/4 ED-IF AI-S lens fitted with TC-301 teleconverter nets a ane:1 image with two or more feet of working room for lighting, etc.
Moving to the Due east-M1, what you accept at your disposal immediately is a much more flexible viewfinder and metering system for use with adjusted transmission lenses. You'll exist able to fit nearly any macro optics you lot want.
Just don't limit yourself to only what is FourThirds or Micro-FourThirds dedicated. There are many, many options.

The Canon MP-East 65 is a transmission focus merely lens that can exist adapted to m43 past the use of an adaptor such as the Kipon Catechism EF to MFT+E-Mount adaptor with internal aperture.

The DOF with the EX-25 between the Eastward-5 and l mm f/2 is very shallow. Certain, it focuses but the range of focus is so short information technology's easier to shoot in transmission, preset the focus past scale and focus by moving in and out. If y'all're too far away or too close it will not find focus. I found with the focus at inifinity it focused about 2:ane or slightly more than from fairly close, at a set distance. Y'all can not focus from farther abroad. At minimum focus distance information technology focused at one:one, very close to the subject area and with a very shalllow DOF. And you need a ring flash or twin flash to light the field of study because at close range you're casting a shadow. I'm not complaining. I'm sure any 100 mm EFL macro lens on whatever format with a 25 mm extension tube would give the same results. And 4/3 has meliorate DOF.
How virtually using a bellows tube?
With the advent of the EM1, things accept improved for four/3 macro photographers. Even leaving aside the IQ comeback and availability of the K.Zuiko 60mm f/two.viii macro lens.
The m4/three 60 mm macro is no better at IQ than the four/3 fifty mm macro except information technology's slightly longer.
..
Adding an EC14 or EC20 to the m4/3 extension tubes doesn't seem to always give every bit great an increase in magnification as I would have predicted (at least on the Zuiko 50mm f/2.0 macro lens), but the organization basically works OK.
The EC-xiv does not increase magnification, only focal length. I assume you hateful the MMF-three adapter tube which provides the correct flange back altitude for four/iii lenses, non an extension tube. At minimum focus with the 50 mm f/2 macro the image size is nigh the same. You lot can confirm this by focusing on a metric scale at minimum focus with and without the EC teleconverter in place. Put the 50 mm macro at minimum focus in transmission mode. Move in until the calibration is in focus. Read the calibration along the horizontal border and see that the image size is the same in both cases.
Incidentally, trying to stack the EC14 and EC20 notwithstanding doesn't piece of work. ...
Why would you do this? Just use a longer lens. Well-nigh SG and m4/3 zoom lenses would be too night to focus. The IQ would drop a lot. The EC-20 is only marginally acceptable on the 4/three HG lenses. Information technology'due south better on the SHG lenses. If you have the Sigma 150 mm macro it's really a 300 mm equivalent. Shooting any longer in macro would exist difficult.
BTW, you tin can couple the EX-25 with the 35-100 mm SHG 4/3 lens for a very cool, sharp 100 mm macro that has neat bokeh.

Re: EM1, extension tubes, and 4/3 lenses
Cheers for the advice, Godfrey.
I do take an assortment of old FD and OM lenses that I've tried on my E5 with transmission extension tubes or reversed (FD only reversed) with the aim of getting significantly >1:ane magnification, but I've been underwhelmed by the results. Perhaps it's my technique. In any consequence, I'll now try them on the EM1.

Nearly infinite macro possibilities
Yes, there are m43 extension tubes available that pass through the contacts... the gear up I got is branded FOTGA, just in that location are others.
Since this is a pass through, and not chipped, you lot could stack multiple sets together if y'all wanted.
for four/3 w AF, you might want to chase downwards a Sigma 105 or 150 macro
in m43 the mZ 60 macro would be a good choice (but I'chiliad holding out for a longer macro lens )
But at that place are other ways to do macro.
When I had my E-500/520, I used:
the 70-300 and 12-50 due west an EX-25
OMZ 50/one.8 w a Zykkor convertible 2X/macro tube
Vivitar 2x macro focusing TC
EX-25
OM Auto Bellows
or some combo of the higher up
OMZ 200mm f4 with one of the above extentions
With the E-M5, I'm using 12-l, 45/ane.viii or 40-150 plus the FOTGA set and/or Marumi DHG 200 (+5) closeup lens.
Of the above, I've gotten the closest west the 50mm + Automobile Bellows + EX-25 (for clearance)
the straight 70-300 was most user-friendly of the 4/3 kit, and adding the EX-25 didn't up magnification much.
The 12-50 is besides very convenient, although information technology doesn't match the magnification of the 70-300
Adding the Marumi to the 40-150 is reasonably convenient, that plus the extension tubes makes a pretty decent macro rig.
I've tried the tubes on the Panny 100-300, simply haven't gotten any useful output yet.
Only there are plenty more possibilities Maybe a Vivitar 90mm macro in OM mount (or Nikon or Pentax mount...) The Panny 45mm macro in m43, calculation extension tubes to the first-class 75/one.8, bashing a FOTGA tube to catechumen the Machine Bellows to m43 mount w signal pass through...

Yep, I employ the 50 mm f/2 both with and without the EX25 a lot. A diffuser with on- or off-camera standard flash does a pretty good chore for me.
How most using a bellows tube?
Information technology's a possibility. Money is a consideration, though.
The EC-14 does not increment magnification, only focal length. I assume y'all mean the MMF-3 adapter tube which provides the correct flange back distance for iv/iii lenses, not an extension tube.
I was talking about EM1/extension tubes/MMF3/EC14/50mm Lens combination. And what I was surprised at was that my metric ruler measurements with and without the EC14 (or EC20 for that affair) didn't differ as much as I would have expected.
Incidentally, trying to stack the EC14 and EC20 still doesn't piece of work. ...
Why would yous do this? Just use a longer lens
I put that in because in the past people have complained about non being able to do information technology, not because I particularly would want to. Except maybe if I were traveling and wanted to get some reach with a very calorie-free rig (presumably with some compromise in IQ, as you correctly indicate out).
BTW, yous tin can couple the EX-25 with the 35-100 mm SHG 4/3 lens for a very absurd, precipitous 100 mm macro that has dandy bokeh.
Sounds adept. All I need is the 35-100mm SHG.

On the other hand, when I deviate from my Sigma 150mm or Zuiko 50mm macro lenses it'due south unremarkably to take a shot of something really small, say 1 to 4mm.

I've never tried using the EX25 with a teleconverter, though I have used it quite a fleck with the 50-200. That combination makes a surprisingly good walkaround macro setup.

It does brand a difference in which lodge the extenders and the ECs are placed. My preference was to first place the extender on the camera and then the teleconverter and lastly the lens. In my experience that combination gave a greater working distance than the photographic camera + EC + EX + lens. Of course my experience was in using the a modified EX-25 (chip removed and replaced with pass through wiring) in combination with the EC-14 and fifty-200mm lens. I constitute it to be a very fun and effective combination which I really haven't used once I got the Sigma 150mm f/two.eight macro.
Incidentally, trying to stack the EC14 and EC20 nonetheless doesn't piece of work. Nor does the EX25 and EX14 combination. I assume the EX25 and EC20 can't exist stacked either, but I haven't tried that.
Your assumption is correct although at that place is a workaround that volition permit yous to maintain aperture control and allows transmission focus every bit long as y'all are non using a focus by wire lens. The Sigmas with their mechanical transmission focus and also the Olympus SWD lenses will let transmission focus.

Skilful question for which I don not have the reply.
I've done a little reading, and it seems likely that the discontinuity on the adapter would role just fine, without vignetting.
I remember the disadvantage (over shooting in aperture priority on a Canon) is likely to be that yous will have to compose with the iris wide open and then manually stop down to the desired aperture, whereupon the screen will go pretty night. For hand-held macros like I often accept, that will be something of a problem. I say that based on having to do the aforementioned thing with some legacy lenses, where I find that I movement the camera a fleck while I'chiliad closing down the aperture, and a little bit of movement is plenty to throw everything off.
