Planars - 2 of them

[Himself]

A non scientific test, for the sake of Planars, and for the fun of meself

All the lenses on tripod, focus on pistil, f/4 because of the last lens, live view, wire remote and being late afternoon small shutter 1/8 or 1/10, iso 160. For sure, with a decent shutter they are sharper than that.
I tried to keep the framing equal for all of them.
Crop 100% for all of them. Didn't touch anything in Photoshop. Straight conversion from small RAW to jpeg.

Contax 50/1.4, f/4



Yashica 55.2/8 ML, f/4



and finally, Mr. mind blowing, Herr S-Planar 100mm f/4
hooked on all 4 Contax rings

the planar 1.4/50 is not doing bad considering that it's an infinity-calibrated lens while the other two lenses are macro lenses.

IMHO you haven't shown these lenses at best, as you can get similar results from a £12 zoom.

My so called test, was made, primarly, in order to see the way they are rendering the colors in close focus photography.
And, I can't find any huge discrepancies in terms of colors and bokeh between 50/1.4 and Yashica.
As for the S-Planar, I wont even compare the images, considering that being on rings the true aperture is bigger than f/4 and as a FL it's double.
