Couldn't resist a set of OM Auto-Bellows on eBay - always wanted some when I had an OM system - and I did still have an OM Zuiko 50mm f1.8 lens, and an OM-E-System Adapter........ so ......

Attached my E-510 via a 25mm extension tube to the OM Adapter to the bellows. Needed the Ext tube so the E-510 cleared the rear of the bellows.

Took a few sample shots. Largest enlargement was 4mm across filling the frame (the "Con" from Table of Contents on front cover of E-3 Manual) - which I think makes it about 4:1. Other shot is part of the II from Sandisk Ultra II CF card.

These were just quick shots - LiveView really does help - using the delayed action to avoid shake and simple lighting. I am tempted to try and find a cheap OM Macro lens and give this thing a real chance at extreme macro. And of course I could put the 2x Converter behind the extension tube!.................

Hi Derek,

I am glad you find joy in the macro bellows. I uderstand your feelings. Next step is to take some flowers, or something more of a 'real life' image.

Did you try to reverse the lens? The original Oly bellows is the finest piece of genious bellows engineering. Reversing Oly lenses is really very easy, you can still focus wide open and stop down just before taking the image using a wire trigger, or the by twisting the knob on the side.

In this image you see the knob I am talking about, but I assume you know that already. The same is used even when the lens is used normally.

Here (http://forums.clubsnap.org/showthread.php?t=261281) is a link to a forum thread about my macro bellows' (I had four, but only have the Oly today). You may find some interesting issues there.

This (http://forums.clubsnap.com/showthread.php?t=263422) is a series of articles, "stickies with the sticky" which includes several interesting macro discussions and posts. Some are written by me. If you are interested, just read, but beware, it will take time to melt.

Good luck with your bellows.

Thanks, I knew you should be able to reverse the lens but didn't have a manual and can see now how its done.

Funny, when I started my E-System to compliment my Canon gear I thought I wouldn't get into Olympus macro since I have the 100mm Macro and also the 65mm MPE Macro [1:1 up to 5:1] and a ring flash for my Canon BUT somehow I got sucked into it.

Here is a good link. (http://www.alanwood.net/photography/) It contains a lot of details about macro photography, also an HTML version of the bellows manual.

If you are just interested in the manual, click on this sentence. (http://zuserver2.star.ucl.ac.uk/~rwesson/esif/om-sif/macrophotogroup/manuals/auto_bellows.pdf) It will give you the complete manual in PDF format. I printed it because you never know...
