thanks Betty (bejoweth) and Fred (fmoore),


english rose: constance spry - fz5 + olympus tele C-180 zoom 14* unchanged colours!
This is the first rose of david austin - growing very high!

I read all the tests and thought that my olympus c-180 is a bad lens, this lens is very similar to the c-160 (price, weight and quality).
But after seeing Bettys pictures I made a short test today with some teleconverters at my own camera:
- olympus tcon 14 - canon tl55
- olympus tcon 14b - olympus tcon14 + 14b
- olympus c-180 - olympus c-180 + 14b



As you can see, the C-180 is the second best in this field and there is no sense in combining these lenses! There are pp filters to eliminate the vignetting - but there is no vignetting with 14* zoom.

I carried the tcon14 around with me for some time, this will be replaced with the c-180 (The tcon14b is too heavy). With this personal test I am understanding the poor results of all moon shots following my first C-180 attempts.

Sven

Sven,

Thanks for the post. Was that rose @ 14X? How far do you need to zoom to get past the vignette? I thought I saw a post about needing to go out to 10x or more with the c-160 so I was just curious if the c-180 was the same.

Thanks for the compare.

-Brett

Hi Brett,
the picture above uses 12x plus digital zoom -> 14x
You need the digital zoom or pp to cut the corner vignetting.
The small internal lens of this converter produces corner vignetting over the whole usable range, starting from 5-6x zoom to 12x.
Reducing this vignetting in pp leads to a loss of contrast range in the corner, but the results are ok for that price.

It was important for me in this test, to see a single element of the picture in the same size.

Sven

seemolf, this picture is absolutely beautiful and I think I'm going to just have to get a C-180 also. Thanks for sharing this picture. WOW!

Lovely Rose Sven

And such an in depth analysis on TCONS, reminds me of Fmoore and his tests on TCONS and WA's

Lucky we got you guys on this Forum

Am tracking my Nikon closeups 1.5 and 2.9 diopter on UPS still in Canada but heading here soon.

John

thanks John,

others have done much more tests with converters and helped us so much.

But I saw Betty's birds, remembered the rose and wanted to know the limits of these converters with my camera. I can look at these power lines from my window and there was a sundown....
Genece is right to warn us, these C-xxx are not good.
But the inner circle (3MPixel) of pictures with the FZ5(!) can be used sometimes.
The bigger lenses of the FZ10,20,30 will have more problems.

I liked the FZ20 and took the FZ5 for its weight.
I posess a tcon14b and carry a c-180 around......

Sven

...expecting your nikon macros soon!

Sven, You want me to get one for you for $9.95 at one of those ebay auctions and send it to you at cost to Germany?

thanks Rainer,
I hope you will not be disappointed! I am not sure how they will fit to your FZ30!
One of my customers is working in NY sometimes, I may ask him to get such a lens for me.
Sven

a late addition:

Disappointed by any combination of lenses, the lenses had to start alone under better light conditions.
I have tested the distant powerline again, a good object to reveal chromatic aberration.
My only interest was: resolution, so all details were increased to same size:

candidates:
- FZ5 12* zoom
- some tcons see below
- zeiss binocular 8*
- hama tcon 4*



results with my(!) FZ5:
miserable: canon tl55, hama 4*, binocular 8*
tcon14 slightly better in the periphery than FZ5 alone
C-180 vignetting, but price/weight to resolution ratio is good
tcon14b no chromatic aberration, but....
B-300 good spot in the center, needs chromatic correction in the periphery

Looking at this test, I start to understand why Panasonic did not sell teleconverters with the FZ5.
