Standard 50-58mm comparison : 18 lenses tested

[CarbonR]

The biggest test I had to do, on 50-58mm lenses :



To facilitate the lenses comparison :
- The 50/1.4 and 55/1.8 together : https://i.postimg.cc/NgQcMyr3/Test-Tak50-55.jpg
- The great old ones : https://i.postimg.cc/GRqc4jKq/Test-anciens.jpg

Industar vs. Tak 50/3.5 : same sharpness but russians do not have "contrast" in their dictionnary
55/1.8 lenses are all equivalent and at the same level than 50/1..4 ones
The Porst is not that bad but f/1.2 is clearly difficult to handle
Lenses with large fungus perform very honestly (it should even be quite correctable) and as expected, the scratch does not affect images
There is indeed a difference between 50/1.8 8 elements and 7 elements, mainly in the bokeh
The Tak 58/2 confirms its reputation of smooth bokeh (Sonnar)
The Tak 58/2.4 confirms the feeling I had about excellent color rendering and messy bokeh
The 45~125 is stille a good lens (did I say it has small fungus ?)
