Besides I think this is prohibited. I spoke to an Ebay Italy person once in chat and he said that sellers must give the full price INCLUDING VAT for auction, and then, if the winner is outside their tax area, DETRACT vat from winning price using the discount/offer space in the payment module.

So does here, it is mandatory.
But besides single country rules, it's the Ebay rules that impose to include vat in auction price. The auction price must be the final price, this is what they told me.

Difficult to say anything about the lens, 0.95 is an impressive aperture but one has to see how effective it works.

I don't think so many people has experience with this lens. I think to talk about this lens same than talk about from a Ferrari. We can talk, but not many chance to get it. So I pass.

There was a time on one of the Nikon forums when a fad to recycle lenses faster than 1.0 was amok. One guy was collecting and reconfiguring them to mount on Nikons - the pictorial results were "strange" nothing seemed in focus, everything seemed to be "boke". But people were paying some hefty dollars for the privilege.

About fast lenses :

"Some of the fastest camera lenses ever made are:

* Rodenstock TV-Heligon 50mm f/0.75
* Nikon TV-Nikkor 35mm f/0.9-Fastest Nikkor ever made
* Canon 50mm f/0.95 (Available in TV and Canon 7 Rangefinder Version)
* Schneider Kreuznach 50mm f/0.95 'Xenon' (Available with C mount)
* Leica Noctilux 50mm f/1.0 (Leica M mount, the fastest lens in production for 35mm cameras)
* Canon EF 50mm f/1.0 (for Canon autofocus SLR, now out of production)
* Nikkor 50mm f/1.1 (for Nikon rangefinder cameras)
* Teikoku Kogaku Zunow 5cm f/1.1 (for Nikon rangefinder cameras)

Some guys were talking about this lens in the Rangefinderforum and they said that it is really a good lens from about f1.4 / f2 on, but hardly usable when wide open.
First you need an excellent rangefinder to be able to focus at f0.95 at all and second the image is said to be really soft wide open (well, of course, one might say).
But then I wonder, if it is worth it to spend a lot of money for a f0.95 lens when you really can use it from f1.4 on. Question

I guess it is a "just-have-to-have-it" thing...

Believe it or not I had this lens on a Canon 7 rangefinder. I took a chance on a ebay seller with 0 feedback and no paypal option and won the pair for $780, this was 2 years ago. This lens is very very soft wide open. What Patrick described as the strange bokeh look was In my experience how the lens performs. My copy I sold for just under $1000 on ebay which is what they still "can" be had for at least in the original screw mount on US ebay. Of course some go for more. This in my opinion is a collectors lens, not for users. The buyer of my lens also was dissapointed but did not wish to return lens. It was a difficult lens to focus, but more importantly, it was not very good at any f stop for the price.
Canon had also a 50 1.2 and 50 1.4 during that era. I have the 50 1.4 on the model 7 body now. It performs OK wide open pretty sharp but not very nice OOF area compaired to some others. The lens does not compare well to the Sonnar 50 1.5 on my Contax IIIa which was much less expensive .
The f.95 maybe would have been more fun to play with if it was mounted on an slr. On a rangefinder with how soft it is. It was just like really sexy woman who does not love you back.

I have this lens -- and no, I didn't pay as much as the amount this eBay auction is fetching Wink
Here's a picture of my sample of this lens (already posted here, sorry):



I have seen many people who often do not even own this lens reporting that it is so soft that is is almost unusable. This is simply not true. The Canon 50/0.95 is a very good lens, which is reasonably sharp wide open at 0.95, at least in the center of the frame. Maybe this rumor originated in the fact that the depth of field is extremely thin when used wide open at or near the minimum focusing distance of 1m. As this lens is usable only on rangefinder cameras, the rangefinder on the camera has to be perfectly adjusted because there is no other way to confirm the focus before taking the picture. I guess many of the disappointed users of this lens were simply not able to focus correctly. With the new digital rangefinder cameras (Epson RD1 and Leica M8 ), it is possible to scrutinize the magnified digital image on the camera's LCD and to adjust the focus and shoot the picture again if it looks out of focus. The advent of these digital rangefinder cameras has driven up the price of all ultra-fast lenses, including the Canon 0.95.

The Canon 50/0.95 is perfectly usable for low light photography, and not only for impressionistic pictures of blurred flowers destined to be posted on specialized Internet forums. Unfortunately, I don't have any scanned pictures taken with this lens at the moment, but here are some links with other people's pictures showing what this lens is capable of:

I would love a f/0.95 lens in my roster before I leave this earth! But guess it will never happen.

You will need to buy a rangefinder cam first. Wink

Thanks! This brings back my hope that very fast lenses still can be good lenses.
When I read these reports that this lens is not really usable wide open, I was thinking about the narrow DoF, but I thought that these photographers were experienced enough to cope with that - apparently they weren't.

I suspect it's the combination of a Rangefinder and F0.95 that causes the problem. Focusing correctly with an SLR and a really fast lens can be tricky enough at times (especially near close focus) and my experience (admittedly limited) with rangefinders would indicate that it'd be even more so with one of those.


Exactly Steve. When one focuses with a rangefinder, the goal is to align the rangefinder patch with the finder's image but there is no feedback concerning the actual focusing of the lens. As the image in the viewfinder is always sharp, a small focusing error due to the rangefinder being a bit off will not show until one looks at the pictures. A small alignment error of the rangefinder which may not be detectable with an ordinary f/2.0 35mm lens will produce blurry images with a 50mm lens at f/0.95.

If only I could mount this monster lens on my Canon 1DS SLR, the image on the big focusing screen would be so bright that I feel I would be able to focus in complete darkness Laughing

Cheers!

Thanks for the links Abbazz. I think I had a bad or poorly CLA'd copy of this lens. None of the photos I ever took with it looked this crisp. The first picture in the second link of the boy smiling at the camera is really telling for me. I am a regular rangefinder user, focusing is different but quite simple. Even when the camera is poorly focused, it is focused correctly somewhere in the frame. The experience I had was of a lens that was truly just plain soft. Since there is such differing opinions and result with this lens. It leads me to believe there are some very good copies and some not so good.

Somewhere in the Nikon Cafe archives are several threads from about a year ago in which a new craze took off for lenses f1.0 and less. One character in particular was changing the mounts to go on a nikon. So I think if you are a good engineer and very clever with your hands it is possible to remount that Canon 0.95, which was indeed one of the lenses he worked on. He was also trying to sell some of them - put a couple on fleabay if I recall correctly.
