A quick lens comparison


When it comes to tabletop photography and product photography, my trusty old 50mm is my best friend. A while ago, while poking around in Darktable looking for lens correction presets, there was nothing provided for this lens, simply because there is nothing that needs correction.

Here is a side by side comparison of the old E series f1.8 lens and the current S series f1.4 (sure, it's not exactly comparing apples to apples, but you get the idea). The results are pretty perfect in both cases, until you look close. As a rule of thumb, the more glass you have the more things go wrong. I was looking for signs of chromatic aberration and soft edges. What I found was trouble with highlights, which is not much of an issue unless you need precision with documenting inanimate objects. The takeaway is, I will be holding onto the old 50 mil for dear life until they pry it from my cold dead hands.









Have a closer look:
