50mm 1,4 - Planar C/Y Vs Summilux R

[radius]

What is your favorite?

[Orio]

I have both. Both are great lenses. My personal favourite is the Planar, because wide open the bokeh of the Summilux has a tendence to be swirly and that is not really my "cup of tea". But other people think differently and prefer the bokeh of Summilux.

In fact I am going to sell the Summilux. In case you are interested, you can send me a message. My price is reasonable.

Thank you. I send you a message.

It would be interesting to test the Praktica bayonet mount, CZJ-built Prakticar 50/1.4 against the C/Y mount one.

According to what Aristide Torelli has written on its blog: from MTF diagram, we can have an idea obout the bokeh.
How the lens reproduces the non-focus areas of an image.
Some lens has a hard bokeh, others much creamy, fluffy.
In order to understand this, we must look the tangential and sagittal structures of 10, 20 and 40 lp/mm.
More them are near (tangential structure of 10 lp/mm must be more near than sagittal structure 10 lp/mm etc...) and more pleasant will be the bokeh.
So from Zeiss and Leica web-sites, you can verify this and you can choose what lens is the best for you.
But remember, I don't have the summilux-r and I have not intention to buy it because I love so much the Planar T* 1.4/50mm
But if Aristide Torelli is right, the Planar is better!

But I miss a thing...
often the MTF diagram is calculated ...
the curves can appear more high if them are calculated using one colour...
the curves can appear more low if them are calculated using more colours together...
so a universal mode of how calculate these curves must be used by Canon, Leica, Zeiss etc... but in reality it is not thus !

so look these shots taken today with my Planar 1.4/50mm
