I use a Nikon D750 camera with a Sigma 105-mm macro lens. To get really close, I used the
Macro ART Variable Auto-Extension Tube made by Savage Universal:
http://savageuniversal.com/products/macro-photography/macro-art-extension-tubeI have tried extension tubes in the past I never did have any luck with them. I found when trying to use all 3, I could not focus.
This extension tube is a one piece, well made, and all metal. It goes from 55-71mm of extension. I used it with my macro lens at a recent indoor Dalia flower show. It was easy to use & easy to focus with the camera on a tripod. I tried both the 55 mm and the 71 mm. I was happy with the results.
The depth of field is shallow, blending into soft focus to the surrounding areas. I was very happy with the results. This was my first time using this variable extension tube.
Well written introduction to a new macro accessory. And the photos ain't too shabby either!
Nice shots Roni!
I have been looking at that tube from afar. Is there any sag or play in the tubes when extended with the weight of the 105mm lens attached? Does it lock up firmly on both the camera body and the various lenses you've used it with? Thanks!

I did not find any sag nor play: the extension is very solid. Even extended to 71mm, it works well. Yes, it locks firmly on both the lens & the camera.
Looks lot like a variable tube I've got for my Olympus Pen camera. It's also similar in ways to the older Vivitar 2x macro converter except that is only a tube and not a 2x TC as well plus it has electrical contacts whereas the others I mentioned do not... What do these units cost ?... I'd be interested myself.
I went to the review & saw the costs. I guess I'm cheap, as that isn't. I normally don't use extension tubes anyway. Thanks for posting it though as it is a tool that many will find useful.
I agree about this lens,ronichas. It is fabulous. I posted a few shots I did with mine not long ago. It's so much fun I can't leave it alone. Your shots are wonderful.
Thanks for sharing and the links!
FYI - Pentax made a version of this in the 60s called "helicoid extension tube" for their screw mount and later K-mount series - also for their 645 series.
