Lets say someone wanted an f1.2 lens for no other reason than it would be cool to have a lens that said f1.2 on it. No specific purpose in mind. Are there any reasonably priced ones? The Canon AF ones are ridiculously priced, but I did see a 55mm f1.2 Nikkor for $210 the other day. Any others that should be considered? Is it silly to pursue that last half a stop when I have two f1.4 lenses?


for cool factor, I would go for a 50 f1.0 and it is more than 1/2 stop better than 1.4 Laughing

Here are some examples at f/1.2.

Minolta Rokkor 58/1.2:


Olympus Zuiko 55/1.2 (focus is off but I've only bought it recently and did not have a chance yet to take more decent shot):


Cosina PK-mount 55/1.2:


Contax Zeiss 85/1.2:


Based on the price, Cosina beats them all, produces very decent results wide open and becomes sharp as hell by f/2.8. IQ-wise, Contax is the best, and Canon 85/1.2L (not shown here) is also phenomenal.

Hello,

for normal shots, the DOF is to small so i prefer other lenses at 1.4 better,
but for effects or night shots the Porst 1.2 is also a great lens.

Here some samples with the Porst 1.2/55mm
(think, this Porst was made by Cosina) Very Happy

First of all, the Lens "paints" like a painter would do.. Very Happy



For nightshots, the Porst is also nice...




Another example



Or in mixed light conditions.



The 1.2 is more an effect lens class under daylight conditions, as shown in the flower picture.. thats why i love such a lens.

Under available lignt conditions i wont miss my 1.2.
The PG 1.2/58mm is the winner, but i havent one. Sometimes i wish to have one, but the work for bring this Minolta lens to EOS Mount and the lens itselfs is to expensive for the small amount of shots i take with a 1.2
For the Porst i did pay 30 Euro and thats ok for having an effect lens of this class. 30 Years ago i shot with a Leica M3 and a Noctilux.. most of the pictures were horrible. But today, a nice 1.2 can bring you a lot of fun in your Cambag.

Given that they are usually 55-58mm, and that the extra glass in there eats some more the light as well, the advantages over a 1.4/50 are very minimal. If you need a night shot lens, go for a 1.4/35 (or if you have money to blow, one of the expensive 1.4/28's or 2/24's) - these will deliver useful handheld results for a stop or two (or even three, in the case of the 28mm ) below the safe margin of 1.2/55es!

Hello Sevo,
i have all lenses i need for these action with 24/28mm or F1.4 Lenses but if i dont want to crop the results, the 1.2 is important for some of my shots.

As you can read in my footer, ive got a lot of the best 1.4/50mm lenses from "the older days". Often i take the Summilux for nightshots, but i like to play around with the Porst 1.2.. and the little extra speed means not only to use the 1.2! Sometimes is important for me to have a shot at f=2.0 and the porst at this aperture has a better correction with this f-stopp than many other lenses stopped down to F2.0. Its not only the 1.2, often the results are better than that what a 1.4 at F2 can do for you..
thats my opinion.

The most interesting thing in 1.2 for me is the bokeh they give.

Here is a short comparison Porst 1.2 vs. Leica Summilux 1.4, same sujet.

First the Leica Summilux at 1.4



followed by the Porst at 1.2





Dont know if you can see the differences, but the Porst bokeh is more "creamy", "glowing" overall and small better color reendering.

And a PG 1.2/58mm Rokkor can do this better for you.. thats one of the reasons, why i like sometimes the 1.2 class.

I like this one very much. The cats expression + the overall lens effect is really nice Smile

Nice picture. One of the reasons why I love the Porst is because it's one of the rare ultra-fast lenses optimized for infinity when used wide open. Usually, these lenses are specially formulated for portrait and exhibit optimum sharpness for subjects located 1 or 2 meters away. The Porst is sharper for distant subjects, making it a great lens for shooting dimly lit landscapes, performances and architecture (interiors). Here are a few pictures taken wide open with the Porst:







Cheers!

I tend to agree with Hinnerker, although I am not a Pro. F1.2 and F1.4 has a fairly noticeable gap between them IMHO.
Anyway here is today and one yesterday's shots (we are baby-sitting more than ten days now, cannot go out and shoot too much).

all at F1.2 click the photo to enlarge (reason is colour is not right for thumbnail photo)

FD 55/1.2 (EF mount) + 5D (I wasn't good to get light in eyes)


Porst 55/1.2 (PK mount) + 5D (this Porst is almost identical to Yashica ML55/1.2, slightly softer at wide open than ML 55/1.2 if you really check it)


Planar 55/1.2 + 5D

Planar 55/1.2 + 5D


Voigtlander APO-Lanthar 125/2.5 + D700 (yesterday, @f2.5)



@pirius Nice shots of kid, and cat
Yes, Planar 85/1.2 is the best (bit expensive for me, I seldom shoot with above 60mm! If I win a lottery, I may get one Very Happy).

@abbazz I have never heard that Porst 55/1.2 was optimized at infinity + wide open, I may try the same thing one day.

I am a retired guy with fixed income! Laughing

f1.2 is fun lens to use. I am using a lot. Only downside is, size and scare factor (expensive piece of glass, whole time on camera... not an intelligent thing to do.. Shocked ).

For low light (esp in city like Columbus, OH.. long winters and lot of cloudy/rainy days.. slow lenses are almost unusable).

Cross posting for different thread,
MC Rokkor-PG 58mm F1.2 EF-mount + EOS 450D.. wide open..

Super! I am curious about both of them! I never shoot on Astia yet and I bought ten rolls.


Unfortunately the film had a bad red-shift. Normally Astia is very color-true. It was out of date so I am shooting another fresh roll this weekend and will have it back next week.

I believe the glow is why people buy such lenses. That and having almost everything out of focus except for one tiny part of the subject.

For the extra 1/3 of a stop of light, its easier to up the ISO 1/3 of a stop (1600 to 2000 for example).

That is very impressive for an f/1.2 lens wide open.

Damn it! I feel with you.... Let's see them on next week.

Now I tried this afternoon of shooting infinity wide open by
POSRT 55/1.2, it was not good at all. My Porst might be Cosina
designed 55/1.2 instead of Tomioka designed 55/1.2. Crying or Very sad

My result was a disaster (sort of), soft and grow around every object.
I may try the same thing with Yashica ML 55/1.2 today or tomorrow,
since our baby-sitting duty was over this morning. Very Happy

I can see HUGE difference between these two --

The Leica Summilux shot is ABSOLUTELY OVER the PORST one Smile Smile

Yes, it is silly.


Atilla,

Which version of the SMC Pentax 1.2/50 do you have?

I have the SMC Pentax 1:1.2 50mm version. I've yet to remove the aperature lever because I think one of these days I'll get around to fixing my Super Program, so for now when I use it on my Canons it stuck as a f1.2 - f2.0ish range.

Fun little lens tho... f/1.2 while super light and built remarkably well (as most Pentax lenses are)
