For tripod i suppose you will benefit from a focusing rail. Sooner or later i'll buy one. That and a flash for non tripod shots...
Btw, i've seen a guy that uses extension tubes, reverse lens and flash with diffuser (and not high end equip) for amazing results (with crazy amounts of shots by his statement):

Here a video with him in action:
Maybe in a future i could try also that (i suppose and old manual prime + some tubes isn't going to cost too much)... Probably just to realize i'm not good on it! :D
 
Good stuff, Essi. Yes, extension tubes are the poor-man's way of converting an existing owned lens into a macro lens. Longer lenses do better, IMO, because they can still be used mounted as intended, instead of reversed. I use my 70-200mm because using my 24-70mm with extension tubes there comes a point in my zoom range where I am focusing on the interior of my lens. Yes, I can focus on fingerprints on my lens. And focus on dust within my lens. That's why the guy in the vid has reversed his 28mm. Doing this on a lens without an aperture adjustment ring, I assume, would essentially lock you into shooting wide-open.
 
You guys have macro lenses already. Don't worry about this other stuff. If you want a higher magnification out of what you have, look at (research) magnification filters you can screw on to the end of your lens. I'm wondering what that would do to your depth of field issue, Prod... I don't know.

On my Canon if I hold down the DOF Preview button while removing the lens it holds the aperture where it's set.

That does work on Canon. I wonder what happens to newer Pentax and Nikon lenses that don't have aperture rings... since they depend on their camera bodies to mechanically control aperture.
 
Essi can tell us about Pentax. Do we have any Nikon shooters here?

I don't knwow that. Until now i've changed lens only once (18-55 wich doesn't has ar to tamron 90 wich has it).

I have a Nikon. If I swap lenses,the aperture remains the same. I'm not sure if that is what you are asking?

No. Essi posted a vid on reverse-mount macro. I was wondering how the f-stop would be managed without an aperture ring on the lens since reverse-mounting loses all communication between the camera body and the lens. I figured it out, so no worries.
 
On another note, you guys got me out experimenting with hand-holding my extension tube setup. It's far too heavy to do this sort of stuff for very long.

So research was done on reverse-mount rings. Roughly ten bucks to reverse mount an old Minolta 55mm that was gathering dust.
 
I'm picking up what you are talking about now. I have never heard of reversing lenses,still pretty new. What would be the benefit it you did that to a lens that is already macro?

Not sure I would want to deal with the fidgeting,I am already anal about getting dirt in my lenses.

Last night I played around with a halide light,ring flash and a tripod. Better results but still banged up DOF when I get super close. Felt like Steven Hawkins with my neck bent up for 2 hours.

In that video he mentions stacking photos,still don't know how he is doing that
Shooting hanheld. Incredible photos.

Probably very little if any benefit in terms of magnification. [In reverse-mounting, the wider your lens the more magnification you'll see.] Your macro is specifically designed for this type of photography, and functions like a proper lens as is.
 
Reverse-mounting is a lens hack for peeps who can't afford another lens, and does not function like a proper lens.
 
I wouldn't consider it if I were in your position, PS. Your macro is far more functional just the way it is.
 
Just another try with stacking, always lantana (younger flower). Tot real flower around 1,5cm

47 photos at f/8 av (shutter time around 0,5s for iso 100), 1:1 to 1:1,1 or little more then cropped and resized...
That time also i didn't focus every shot, just focused on first shot at 1:1 then turned a bit focus ring, shot again, turn, shot, etc... Need focus rail.
Too bad i accidentally hit the camera in last 3 shots and i've discarded them (they were moved just a bit, i suppose sw could have handled that), some out of focus areas at the end...
Meh, looks like i have dirt in the sensor...
Edit: should have been some dust, did an auto clean then tried at f/32 and now all seems fine...
