50mm f/1.4 battle. The Prakticar is version 1. I was surprised about how soft it is at f1.4, reminds me of the Zuiko 55mm f1.2. Feel free to comment on the performance.
The camera is the Sony a7, tripod mounted, 2s shutter delay, e-FCS off.
Prakticar f/1.4:
f/1.4 100%
f/5.6 100%
Planar f/1.4
f/1.4 100%
f/5.6 100%
Planar f/1.4
f/1.4 100%
f/5.6 100%
Prakticar f/1.4
f/1.4 100%
f/5.6 100%
Bokeh comparison, color adjusted.
Prakticar:
Planar
The Planar has better bokeh. |

To my eyes, the Planar looks more clinical while the Prakticar looks more artistic.
I think that in my own photography I would have more fun and produce more pleasing results with the Prakticar.
I really like the colour rendering and the way that it paints.

Thanks for comments!
I am also thinking that maybe something is wrong with the Prakticar. But is has no signs of damage and does not seem to be worked on. And stopping down to f/2.8 makes the glow disappear. This speaks against there being any fault and makes me think that it's just the character of the lens. I have a rubber lens hood somewhere to try, but don't expect it will help much.
Ian, is your lens also version 1? |

The first version of CZJ Prakticar 50/1.4 is known to be really subpar. It seems it has gained its outrageous price just for being f/1.4 and having a "Zeiss" label.
Simply go for the second version if you want a f/1.4 Prakticar.

Yes mine is v1, and no, it isn't known for being subpar, in fact, it should be superb. Same with the 1.8 version, which is a serious rival to the Planar 1.7/50. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

Could you provide some Praktikar images and 100% crops taken at f1.4? That would help to clarify your statement ... thanks

I had 2nd version of Prakticar few years ago as well as Planar 1.4/50
I've made some comparision beetwen them and I may say - there was no much difference in sharpness at f/1.4
At least I can't say that Planar is much sharper than Prakticar. I'd say both lenses perform very well wide open.
As fore bokeh - I always prefer Carl Zeiss Jena lenses to Zeiss from West Germany. Yes Zeiss Oberkochen lenses are more modern and their bokeh is too proper, but Jena lenses bokeh is more artistic and unique.
For example - Carl Zeiss Jena Pancolar 1.8/80 is quite more appreciated by the collectors and photographers comparing to Zeiss Planar 1.4/85 for C/Y even despite the fact that 1.4/85 Planar is faster and optically more complete.
If i find test shots of mine Prakticar 1.4/50 i'll upload them. |

I was about to ask the same! If I have a faulty copy I need to get it replaced.
It seems to work best at close distance when wide open.
Some more samples. With a few edits.
2.8 or 4
Oh, and this lens has that 3d-look. (when making stereo images) crossed eye viewing for 3d.

It's not uncommon to have such differences in bokeh.
It's just more "busy" or "nervous" bokeh, due to design. |

I think here due to different dof placement, or, possibly planar highlights overexposure. Prakticar focus is slightly farther away, so bokeh highlights are more in focus. Identical focus would have produced very much more similar results, imho. _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮

The focus is almost the same give or take a few mm. Not enough to make a difference. Different optical designs creates different out of focus highlights. They are exposed the same but the Planar has a shorter shutter speed due to it not having yellow glass from radiation.
I have made a big bokeh test with over 40 normal lenses that I have not posted yet, I could do if there's any interest. Lenses with similar design have similar bokeh, I think most will agree on this. |

I agree! A bokeh comparison of different lens designs would be awesome to see. Identifying character by design certainly narrows selection o lenses.

Here is the comparison:
http://forum.mflenses.com/viewtopic,p,1504047.html#1504047
After the time that has past since posting the test I think the test should be redone with better subject and background and better naming of the lenses to avoid confusion.
I would like to have a smaller subject and a more detailed background to give more bokeh to judge. |

The film simulation is Velvia - hence the strong colour

Nice bokeh and sharp enought.
The planar, sharper and with more constrast has some CA . The Zeiss ZA is a bit sharper with less CA.
neither would be my choice for everyday use |

When used correctly you see less of these weaknesses. I usually don't use f/1.4 at infinity. And up close f/1.4 looks a lot better. The C/Y Planar is an everyday lens for me. Stopping it down makes the images not only very sharp but they also have an extra quality that I can only describe as crispy or micro contrasty.
I agree the Prakticar looks similar to the Super Takumar. |
