hello JP,
thanks for the replay!!!

the price depends on the state of the lens,
however and usually, for buyers is always too high and too low for sellers ...

you make me a proposal, even if you have photos would be better

many thanks
Roberto

Hello to all
as the title suggests, I am looking for the lens at a "decent" price

many thanks
Roberto

Hello Keith and thanks to you for your help, AHHH you also Pentaxian! :D interesting discussion that you linked! attaching two tests made ​​with the lens hood and one without, tell the difference http://www.photomacrography.net/forum/userpix/3477_D_1.jpg WITHOUT__________________________...

Hello to all!!!

I followed the instructions of Pau and things get better again ...

Hello Pau, Thanks again for the help ...
I figured it was better to smaller, Today and tomorrow are away for work but as soon as I try and I'll know ...

P.S. but if there are other suggestions I would be happy to receive If the issue -as its seems from your last post- is reflection on the front lens, a small light hood would effectively surpress that reflection. You can make it with a cilinder of black matte material Hi Pau, thanks for the help!!! ...

Hello to all, good news ... I solved by making the diffuser cone (see attachment) and things have improved a lot, the test was done quickly without pretensions, but already you can see the improvements ... I tried to cover the entire inside of the paper with matte black but does not improve the situ...

yes!! the direction is right ...

Do the individual frames in the stack all look similar? I mean to each other, and the output? Be sure to check your individual frames as ChrisR suggested. If the individual frames appear OK (high contrast details), then your problem may be in the stacking. ..... --Rik this part is not clear to me, ...

the JML is the first time you use it, this lens is always spoken very well ...
I could not believe my eyes after seeing the result.

I tried both with the paper tube long and one just short, but more or less always the same problem


it is better that I do conical?

Hello Chris,
many thanks for the reply!

yes! I had already thought to internal reflections but there are none, for safety I put a perforated disc of black card, but did not improve anything!

the second photo is made with Vivitar 55mm and tubes

Hello to all, I need your help please: I took a JML 21mm and I'm starting to use it on my set for macro but the first results are unsatisfactory! What's wrong? I have a Pentax K5 (CMOS 16MP), a rail controlled by SW and 4 LEDs for lighting thanks for any suggestions! Roberto http://www.photomacrogra...

no problem ... Chris
indeed, better to have more information as possible since it's all new to me ...

the problem is to find them at this point!

and thanks to all the answers and also to those who will want to tell her ...

Roberto

thanks to all ...
then I will try one 4x or 5x

Roberto

P.S. if someone has it to sale

thanks again Chris...
then the "best" solution around 5x is an objective microscope, instead of other solutions ...?

Roberto
