My dream lens for the G2 - it's hard to find one at a somewhat decent price. I am still looking. That picture is just great!

that photo almost has no distortion
i wonder what a 16mm photo is like WITHOUT the center filter.
anyone have one to share?

Translation:
v Verzeichnung in % der Bildhöhe u = v Distortion in % of the image height u
As you can see in the graph the distortion starts outside of the image frame. Up to 18mm on the scale it is zero. The 18mm is measured from the center (2x18mm=36mm image width).
DEAR TOYOTA DESIGN,
The Hologon graph gives the distortion a little nonzero value near the corners of the frame: their distance from the center is roughly (18^2 + 12 ^2) ^0.5 = 21.6 .. mm.
At the middle left/right edge (or at 18mm from center) there is no distortion, as you rightly state, but the frame extends into the corners and your geometry needs unrusting a bit and the Zeiss graph needs to extend out to 22 mm as it does! Right triangles, Pythagoras; no more.

nevertheless, it is mad good for distortion control for such a wide lens
hmmm if only i have the money to try one.

Reasonable price for 16mm Holongon

There are some such lenses sold in Japan with a price about 1000Euros.
But Japanese are Japanese, they never sell the thing oversease!
But I can manage to get one.

This Holongon is a superb lens and almost a must for G users.
Pls see the price for another Holongon Zeiss made for Leica--- over $10,000!
So, it is very worth trying!

True but I would be really surprised if anyone could spot such a tiny distortion that only happens in the far corners without the help of some instrument.
I think that, for all practical purpose, the hologon can be considerd distortion free.

can ppl post more photos from the hologon?
what about photos without the center filter?

I see no use of the central filter; some lenses might need it, but I do without and can barely see any vignette with the G Hologon at all. Maybe I am just lucky, or blind, ... or who knows.

Hologon lense design and patent
Hi all,
nice to see those images from the Hologon. I have a black contax g2 with 3 lenses, but alas, no hologon yet! I did found the patent that was filed for the design of the lense, see here. For more Contax G2 links, try this one.

I see (above) this lens on a ZI and on a Contax G....It's a G-mount correct? Is there an M adaptor available >>> an M-mount? Is it a screw mount? Will other G lenses adapt to M- with such an adaptor...?
Sorry about all the Q's, but those photos are VERY nice...

Hi,
the hologon lens for the Contax G2 has G mount, and AFAIK there is no M mount converter available. I read some old postings that a few small companies can modify the lens to fit M mount bodies, for a lot of cash. Maybe your best bet would be on the 15mm Zeiss Distagon for M mount, with similar low distortion. Still a steep price though !
Here is wat Erwin Puts says about it.

If u are talking about the ZM 15/2.8 Distagon, then as far as distortion control is concerned it is far from Hologon. Distagon is about 3.75% and Hologon is close to 0%. However the Distagon has higher resolution, much faster speed and allows TTL metering.

did you use the centre filter for it?

two images I recently took during my trip through Andalucía:
Sunrise at Vejer de la Frontera
Plaza Mayor at Vejer de la Frontera
Beautiful shots. Out of interest what film did you use for these? The colors are very nice.

ps- I have a Hologon 16mm in M-mount (converted) arriving today, very excited. I also have 2 G2s withevery lens BUT the Hologon, ironic I'll have the M-converted version instead!
Talk to Ken Hansen in NY. He sells these lenses fitted for the M and knows their limitations. If you want his number send me a PM.

zeiss hologon ultrawide
zeiss hologon ultrawide
:angel:hi ! i tested a zeiss hologon ultrawide on 1972 when i was a zeiss dealer
on FNAC shop in Paris France!...
i did a roll of black and white film 36 exposures,and as the results where
fantastic i could sold the camera to mister LISSAC the owner of a chain of
optical glasses in France!...
the camera was equipped with a f 8/15 mm fixe mounted lens without any
focusing because of the very important depth of field!...
the camera was sold together with a hand grip in order to avoid taking picture
of your feet or fingers!...
and also with a special filter from zeiss in order for the differrence of lighting
from the edge to the center of the picture!...
it did accept the interchangeable backs of zeiss contarex to be able to change
from color to black and white in mid films:you needed two backs for that!...
the angle of wiew was of 110 degrees free of distostion if the bubble level
on the upper part was centered!...
it's price complete was 5800 new Francs (with one euro = 6.55957 francs and
1 euro= 1.586 us dollar...
i did two searchs one for the picture of the camera on my favorite search
motor:i found on e bay one man of poland that was selling one for...4200 us
dollar ,complete and brand new...
but unless the taxes and custom fees where very high in soviet poland,between 1972 and 1974 it seems an excessive price!...
paiement by visa or bank to bank payement was possible!...
so if your bank says O.K!...
for the Zeiss interchangeable contarex backs ,i found two on e bay,for 30 us dollar each:it is a good price for the 1972 price was 1100 new Francs!...
by the way it seems that only 1,400 Hologon had been manufactured and sold througout the world!...
in paris we have two workshops repairing the hologon and the backshoto cine MS and Vilma!...
yours truly!...

The Zeiss Hologon Ultrawide is an amazing camera. I'm still looking for the correct filter. I bought the handgrip a couple of years ago for a paltry amount (less than $50).
When Zeiss Ikon folded, some of the Hologon lenses were refitted to the M mount, making it -- I believe -- the only official Carl Zeiss (West Germany) production lens for the M, until the recent ZM products were offered.
You have to think of the Contarex Hologon as an aperture priority camera, because it's a fixed f/8 aperture and you adjust the shutter speed to achieve correct exposure.
I have a short writeup about the camera on my site. I might go ahead and use it without a filter and shoot some slide film.
