that's good news then!


No, I think you will find that the total figures at the bottom of the chart (in four digits) clearly show the Canon FD 55mm f1.2 SSC is the best lens of the bunch, then its the Canon AL version, then the Minolta Rokkor 50mm f1.2, then the Noct-Nikkor 58mm f1.2 and then the Pentax 55mm f1.2, with the others trailing behind.
The worst of the bunch is the Konica Hexanon 57mm f1.2.
I'm supprised at how poor the Leica Noctilux performed, at second worst, given the huge premiums they ask for their lenses!


Cool!

So, let's celebrate the Canon's first place from this test then! Smile

shot taken at f1.2 (I think that the bokeh is simply great ...)

Just to make sure,
bloom at high contrast = CA/Purple Fringing ?
reflections against light = Flare ?

Well, we dont know if the test is very realiable or not, but as our friend DSG said, any test data is always welcome and I want to rewrite the table in English, based on kuuan translation help Smile

according to this test, my lovely zuiko 55/1.2 would be crappy against the other.. well, despite that it makes great photos Cool

'Überstrahlungen' bei hohen Kontrasten = bloom at high contrast:
I believe that this is light at borders from very bright to very dark bleeding into the dark

Reflexe bei Nacht und Gegenlichtaufnahmen = reflections when taken at night and against light = I guess that's above all flare

I hope someone else, more experienced, can correct or confirm.
note: I had made a typo earlier, it said: 'reflections against and light and against light' correct is: 'reflections at night and against light'

These total figures are obtained by multiplying the individual scores by factors between 2 and 12, weighing them to obtain a total score for how each lens performs
at the 4 applications / circumstances described at the bottom of the chart.
An other way to get to totals scores would be to simply add the individual scores.
that would make an order: Canon 625, Minolta 634, Canon Al 637, Nikkor 647, Pentax 652, Oly 659, Yashica 681, Nikkor Noct. 692, Konica 818, Leica 852 ( well, if my fast adding is correct )

Anyhow I believe that best to weigh the individual scores according to one's own application / preferences.

Thanks again Kuuan.

By the way I wonder about Hexanon. I just went to this site that said Konica Hexanon 57/1.2 "said to be one of the sharpest f/1.2 legacy lenses wide open". But the test tells otherwise.

Because the man behind the camera & lens that matters Smile
Besides, all the lenses above are more than good lens.

+1 Ask whether a specific lens is sharp or not you will probably get completely different replies from different people, depending on what lens they have used. So unless I see a measured MTF and use it myself I am no longer placing much weight on others opinion, except for those who have used many lenses.

And I am wondering how they get the number in this chart. Confused

In summary I own/did own the following 5 Lenses..

Here is my personal ranking after compairing them

1.
Canon FD 55mm AL f/1.2
Me i love the Bokeh better compaired to second placed Non AL Version

2.
Canon FD 55mm f/1.2

3.
Yashica ML 55mm f/1.2

4.
Minolta MD Rokkor 50mm f/1.2

5.
Pentax SMC 50mm f/1.2


I do have both Canon SSC Versions converted to Canon EF Mount..


Me, i clearly prefer the AL Version, but unfortunately this lenses are not usable in a regular way on a 5D MKII without losing infinity.
or shaving the mirror. Because of the protruding fixed rear element on the AL Version, its also neccesary to get rid of the small metal piece, sitting in front of the focussing screen and holding the foam for mirror damping (if you want to get infinity)..

The depth of indentation is to high and the diameter of the rear lens is physical wider as the mirror box-part itself, so the rear part stays in physical contact/hit the inner part of the Camera - Body...

If you try to reach infinity with the AL Version and take the old FD rearpart of the lens because of the "lens holder", (i have seen this in many conversion stories, max 10 meters will be possible)..

Most modification are done this bad way.. because of the limitations i wrote..



They simply did take the old FD rear part with the rear lens holder and transplant to a new EF Adapter, because they need to use the original holder for the rear glass, which is tightly mounted on the FD part!!..

But this old part of the mount will catch the mirror at about <10 meters... and in addition to that, this is "hard limited" because of the large diameter of the FD rear part which will shorten the contacts on EF Lenses contact block on camera hole of the Canon EOS Cams if you trying to come closer to infinity !

A better way is a new machined part together with an M42 or M39 Adaptor.. the rear lens can intrude better, without shorten the contacts on the inner contact block of the camera !! An the rear glass is the only limiting factor and not the old FD Part !



OK, its a bit Off topic... but maye an interesting hint for some of you..

My conclusion after converting lots of Non AL Versions and the AL Version:

The AL Version is one of the best lenses i've ever seen in my life.. sharpness, bokeh, contrast, rendering etc.. are top of the notch..

For a long time I loved the Canon 1.2/55mm SSC Non AL as the best of the bunch, until i converted the 1.2/55mm SSC AL !!

Or like i stated in our german forum..

Le roi est mort, vive le roi !

Well, my "too-quick & naive" assumption is that the test was done by an expert or done in very measured condition Smile So even if the test is a little bit hit and mis, the sharpness level of Hexanon, if the lens is really sharp, was not decreased drastically like in the chart.

But you right, we dont know how the tester get the number Smile
Let's call it a 'mysterious chart' ... haha Smile

Wow, I should try the AL then Smile And Yashica too.

About hitting 5D mirror, I have to use live view when using my 55 non AL, beyond 1.5 - 2 meters.

By the way since the AL version is radioactive, is there any yellowing effects you've seen on the lens?

I recommend the Canon FL 55m f1.2...Much, much easier to convert than any of the FD versions, cheaper to buy and its better than my Carl Zeiss 50mm f1.7 Planar T* when stopped down a little.
In fact its the sharpest 50(ish)mm lens I have ever used. Wink

Hello,

i can see the yellowing in the glass of the lens, but not in the pictures!
So i dont know, if its a part of the coating or because of the thorium..

Here are some links to high resolution pictures, taken with the Canon 1.2/55mm SSC Aspherical at f1.2 in sunny daylight condition.. no further processing.. taken with the old EOS 400D.. so you cant see any yellowing effect.. and keep in mind, pictures taken at f1.2 on an old crappy 400D with his very small viewfinder.... (mice cinema!..Very Happy )

On a later stage, the conversion will allow to work with that Lens near infinity on a 5D.. at the moment only possible in LiveView mode of the
5D MKII

Theme up! After 7 years of pause Smile
I've done another review - Canon FDn 50mm 1:1.2 with some tests
Still can be actual for today
