Here is some possible useful information...
Well, I picked up my fastest piece of glass ever yesterday.
50mm f1.4.
So, I decided to see how this one compared to the 50mm f1.8 I already owned.
(I couldn't pass on the 1.4... it was a good deal.)
So, I decided to set up my tripod and try 3 different f stops with each. The photos
are at 1.8, 2.8 and 8.0. I didn't feel like doing anymore. I have been lazy lately.
I forgot to mention these are 100% crops.
Anywho, check the glass out on this thing compared to the 1.8.
Here are the comparo pics.
