FUN! FUN! that combo makes for some really great fun AND MACRO files.

I usually use the 10mm with mine because most of the time I am not close enough to use the 16mm and have never used the 26 stack on the m40-150.

I do use my EX-25 on my 70-300 and that works very well too, but the m40-150 is so easy to use.

Glad you are having fun with it.

Question, how close are you to subject when using the tubes? If I could return my micro nikkor to the 35mm case... hmmm

Depends on what zoom setting you are at. It varies. You set yourself up at the distance you want to work from, then zoom the lens until you are almost focused, then AF to perfect the focus. The longer the zoom, the more working distance you have. You can be very, very close, or back off, depends on the subject. Flowers, no big deal. Get as close as you want. With bugs and critters, you back off and stay out of their comfort zone so they don't take off.

It also depends on the 'tube stack'.

The greater the stack the closer the focal length; i.e. 16mm tube will allow focus closer to subject then will a 10mm tube and 26mm closer yet.

The zoom or physical near focus technique remains the same (either zoom the lens or move the physical distance)

The 75-300 M. Zuiko I use with the Kenko tubes will focus down to 2.99 feet or so. That's in the Olympus literature and what's marked on the lens. What they DON'T say is, it will focus down to 2.99 or so feet at only one focal length.....75mm. From 76-300mm, the minimum focus distance is 5 feet, so I use the tubes a lot with this lens, and primarily the 10mm tube. Once you extend it to 16mm or combine the two at 26mm, f8 does not get you much depth of field. You don't exactly have tons at 10mm either, but it's the best case option.

With the 10mm tube the 75-300 is effective from a few inches to around 4 feet or so, which I use a lot to shoot closeups of blooms in beds where I cannot get physically close to shoot, like at the Arboretum or Fort Worth Botanical Gardens, where employees frown on patrons walking into the beds.

Hi,

I already have the 35mm (4/3) and the 60mm (m4/3) macro lenses ... but this combination (at least with bees) makes me way more comfortable.

For those shots, I was between (I have to remember) 2.5 to 3 feet from the flower.

Regards,

Gilles
