Hi Kuuan,

Just a Question re: 50 1.4 and 50 1.5 canon ltm's
I believe You have Both

Correct me if I am wrong , the 1.5 is a sonnar design, the 1.4 a planar design
Do you prefer One over the other... ?

is the1.4 really any 'dreamier' than tbe 1.5 wide open

Thanks in advance for your Thoughts

Hi Helen,

yes indeed I have both Canon LTM 1.4/50 and 1.5/50
yes, the f1.5 has Sonnar design while the f1.4 is a Planar / double Gauss design ( there is a ver1 and ver2 and sources are not clear about their optical design and if they differ optically, see: http://aperturepriority.co.nz/2013/05/28/the-japanese-summilux-canon-50mm-f1-4-ltm/ and http://forum.mflenses.com/confused-about-a-canon-50mm-f-1-4-ltm-t72018.html ( mine is a certain version II )

The f1.4 is contrastier with the more modern look but nevertheless 'vintage' colors, the f1.5 is more dreamy, of course specially wide open, low contrast. Generally I like Sonnars but have struggeled with my f1.5 and have been using the f1.4 more often. I consider the f1.4 to be the more generally useable lens, but other see that differently. ( see link below ).

The above has been my impression so far, but comparing the test photos that I had done recently, and which had been used to make a neat comparison tool by 'Martin', the difference isn't all that striking, see: http://www.lenshunters.com/tests/a7-normal-lenses-test/
personally I really like the colors of the f1.4, it also looks a tad sharper. Sharpness loss towards the corners, most likely due to field curverture, is more pronounced with the f1.5, but extreme corners of the f1.4 are weaker. Surprisingly I prefer the oof rendering / bokeh of the f1.4.

there had been a thread here where more experienced members compare these two lenses: http://www.rangefinderforum.com/forums/showthread.php?t=22472
same and other people also compare them here: https://www.flickr.com/groups/780587@N21/discuss/72157615148696880/

my photos taken with the f1.4: https://www.flickr.com/photos/kuuan/sets/72157644035549161
and the f1.5: https://www.flickr.com/photos/kuuan/sets/72157644035549161

Helen you certainly made me plan to take out the f1.5 more often, thank you for that, best greetings, andreas

My Canon 50/1.4 seems to front focus on my M9 :(

I think I've read that this is common on digital M's. Anyone else?

My lens seemed to work nice on my M2 though...
