member tb_a, Thomas had asked me for infinity test of the <Canon LTM f1.4/50mm, see: http://forum.mflenses.com/advice-sought-for-ltm-50mm-lens-selection-t72280,start,50.html
also included:
Canon LTM f1.8 'black', Canon LTM f1.8 Serenar, Canon Serenar f1.5/50 and Helios 103 f1.8/53
all shots taken RAW with Sony A7 @f5.6
imported in LR and edited: Auto WB, + 25 whites, - 25 blacks, + 10 clarity ( these old lenses require some added contrast anyway, and today is a very grey day ), exported as jpeg
+ my user error, take with Serenar f1.5 was underexposed, +3,3 exposure in LR
the scene:
100& crops, not really center, but near to, on top of center:
Canon f1.4
Canon black f1.8
Canon Serenar f1.8
Canon Serenar f1.5
Helios 103
and 100% crops of far top right corner:
f1.4
f1.8
Serenar f1.8
Serenar f1.5 ( focused on the building seen in center crops, if focused to the corner it may fare better, Sonnar typically have strong field curverture )
Helios
I may repeat the test on a better day, possibly better motive and more lenses
cheers, andreas _________________ my photos on flickr: https://www.flickr.com/photos/kuuan/collections |
