Mist probably
Homoneura but impossible to say for certain without a better view of the wing.

again a great photo,

He uses a long focal length lense.

Sigma APO 150 mm (very good lense and expensive).
the material you can see here:
http://www.fotona...chas/2030/ 
See equipo (equipment in Spanish).
The photos are one of the best I've ever seen - butterflies and birds and some odonata.

hi Jorge,
i have the same lens and just buyed a new camera (40D) hope that i will try that one in the field next week.
Canon MP-E 65 will be my next lens.
now i know the gear i'm really interested in the technic he use.
thanks for this for now,

canon 40D is the next camera after mine canon 30D. It appeared in August this year. The review I read seems to approve the camera.

I have a friend of mine that will buy a canon 40D too..
Canon MPE-65 is rather hard to use! Not just lightning issues but handling it.

I have a similar setup when I reversed a 50 mm lens on my Sigma 105 mm and it is not easy. You can see some photos here:
www.flickr.com/om.... They are all mine.
I advice to buy a Tamron 90 mm instead a Sigma 105 mm lens, it is a little better (ok, the working distance is a little smaller) because delivers crystalline photos.
I use usually jpg format, but the RAW files are much better because there is no lack of information. jpg file compacts the information, and it has the disadvantage to loose some quality.
The first lens I will get it is a MPE-65 mm and then maybe a Sigma APO 150 mm.

Hi Jorge,
i think you are wrong, the correct link to Rafael Estevez (Rafael Estevez Rodriguez) page is:
http://www.fotonatura.org/miembros/fichas/7957/
and a gallery at:
http://www.fotonatura.org/galerias/1205/
hi have a complete different gear, mainly Nikon.
the link you have gave is from another person.
still waiting from Rafael to say something about his technic (if he want).

No, gallery is at http://www.fotonatura.org/galerias/3946/
I think it is his excellent lighting technique that makes the photos special.

I have the same Sigma ring flash (on Canon) and I think it sucks (or maybe I don't know how to use it)

ring flash turn the light in someway "hard". more darker...
the better is to have a very good diffuser.
With MPE I will not use ring flash.

We should perhaps discuss photo matters in another thread. In larger magnifications a ring flash doesn't work well with the MP-E 65. The focal distance is so short that the flash gets in the way ...

I also got a SLR with a 105mm Sigma Macro and a Ring flash. Right now I am experimenting with it. I also found that many times the flash is too hard, particularly in low light situations, and when the TTL program can not judge the light conditions right.
I think it is a good idea to set the flash intendisty to -1. It consistently gives better results, it is much easier to compensate for low light in photoshop than get rid of overexposure.
I think I'll try to attach a sheet of fine paper or a greyish foil on the top of the flash to get a more diffused light. I think it will do the job. I'll experiment around with the flash in winter.

first of all sorry for all OT on this thread (maybe Paul will move partly in other section).
on macro ring you can't use that diffuser.

#20
this is precisely the diffuser that Brian use with MPE (even for 5x magnification.)

Much better than ring flash... that has the problems crex appointed.
yep. it would be better to have another thread.
