Wow, that is amazing, but I must ask, is it still as portable as it was before your mods?

Hi nizidramanii,
all parts can be removed, there is not a single modification to the body.
The heavy lenses are for stationary use, I have better attachments for smaller lenses (using cockin filter attachments).
So it is still portable!

Sven

- the most important part at the moment is the "portable" remote release -

I thought it is the right time for a minimalistic approach.
This is a quick and very dirty remote release:


You need:
- double sided velcro tape, with a hole in it.
- a hard plastic plate with a 2,5mm drilled hole below (eg LEGO 2*2 plate)
- wire release or deluxe pneumatic release

Ying:
minimum amount of time and material
Yang:
many buttons have to be set before this part is applied.
(my LEGO part allows control of all buttons)

This is the other extreme - expensive version:

This is my first electric release for the FZ5.
I used some pneumatic solutions lying around from my old LEGO technique days :-)
Parts:
- autonomous pumping station
- electric-pneumatic release
- electric switch

A 9V signal triggers the camera now.
Mindstorm is waiting to take over with contact, light and ultrasonic sensors. My birds at the feeder can trigger their own portraits now!




(please don't forget, there is still carnival in Germany...)

Amazing. I think I'm going to wait for the FZ6 and hope that it has remote shutter release. That's a feature I really want, and the pneumatic stuff seems a bit, erm, much :P

well nizi..

I missing some more features:
- live pictures via USB on my laptop
- remote control of all functions via USB
Impossible? My canon A70 had these features!
Panasonics development crew should develop an open software interface.
The open source crew would do the rest!
Sven

one more:
- power via usb

the pneumatic version was inspired bypictures of STORM or GOLDBERG

..but the cheap version is better than nothing?!

I am still gathering my tech info here:
This is Table of achromatic lenses:


Minolta, Olympus and Nikon- the manufacturers are fading away.
Raynox is ok, but +4 diopt. is quite much and the lens is vignetting below 4*zoom.

All my lenses were bought at ebay - mint condition.
So look at the table if you find used lenses.
distance_cm is the distance between the front lens and the object at 12*zoom.
camera setting from 2m to infinity FZ20,30 or 0,7m to infinity FZ4,5,7
So the mcon35 has a distance to the object between 30 and 35 cm.
Please correct me if I am wrong!


!!!! If you need more reading, look at this page: !!!!!
http://home.planet.nl/~heuv0283/achromats.html

This is our former reference on achromats:
http://www.angelfire.com/ca/erker/closeups.html

Sven

if you need some information about teleconverters look at this.
(perhaps you don`t need one afterwards..)
these are extreme crops calibrated to same sizes - to examine the resolution.


I have seen many test of tcons. Some show cropped details, but there is no comparison with original 12* pictures. Many were done with different cameras. There are great differences between FZ5, FZ20 and FZ30! Other tests with the FZ5 did not test the resolution. So be careful!
Shene pointed out that tcons are not suitable for low distances (without achromats).
I will sell most of these useless tcons. There is no more sense in combining them (looks good, but...)
But here is a better solution: Digiscoping!

My first tests were a disaster with the FZ5 and I preferred my canon A70.
Microscopic experiments showed, that the FZ5 can look through many glasses as well.
The picture shown above is just a first digiscoping test with:
FZ5 12* zoom, orthoscopic eyepiece of my microscope, 500mm mirror SLR Lens.
Not a real spotting scope, but a promising start.
The object is hundreds of meters away.



This is my answer to all those freaks combining teleconverters (this one is bigger!)
;-)

The art of fixing something to something.

I am tired of searching adapters for adapters, or even reverse adapters......
But I needed a fast system to attach special lenses to my cameras. Fast and centered of course!
This is my solution:


I am using a cokin system A, designed for square filters and various threads.
The A and P system cover the whole range of threads 40,5 - 62mm or 49 - 82mm!
This versatile system will be your friend for many generations of cameras.

I did cut a round opening into the cap and fixed a 39mm thread for enlarging lenses into it.
Reversed lenses are surrounded by a compressable but stiff foam. (there is a 28mm takumar)
They are stuffed into the sun shade and have a "firm grip".
The equipment is centered and can be changed fast!

Hope you like it (especially Francesco!)

Sven

Here is an example taken with this setup:
"iceflowers" growing on my window - 35mm reverse

You are really a Wizard, Sven.
Owing to my studies I have currently not much time to experiment at home.
I'll keep the 24mm F/2,8 WA as a microscope for "homework", and I'll evetually buy only one inversion ring (I hope to find a 50mm F1,4 with 52mm thread).

I don't know If you are practical of dSLR.
I tried a 50mm F1,4 Nikkor rev, macro on a Nikon F100 (?) and on a Fuji S2Pro: what you see in that OVF is really miles away from the EVF of FZs...

Anyway I hope to find more time for practice with the rev 24mm.

It seems that distance from thee FZ lens (tube)does not affect vignettting, and neither adding 6T+5T before or after the WA does anything...

Thanks for your infos, these posts are really a mine.
You really should take a webspace of your own and build up a true website with your discoveries, suggestions (not only a photo gallery like Zoto)
