I picked up a 50mm f1.4 Tak "Super-Multi-Coated Takumar" serial 4818670 from KEH a year or so ago and I didn't use it back then because of an odd yellow color cast. It became a shelf queen until a few days ago when I threw it on my Olympus OMD EM-1 and took some shots. One thing I noticed was that the images were free of this yellow color cast, at least on review. So I threw it on my K3 and found the same thing, the yellow color cast was gone!
Odly enough when I threw them into lightroom 5 the preview image shows what I saw on the back of the camera, but once LR5 processes the image after I click on it I get a green color cast. White balance on the K3 and the OMD was set to auto.
My eyes are crap anyways because I back focused from where I thought I was in focus according to the view finder, but thats nothing the camera can fix, only me getting to an optometrist.
I really want to enjoy this lens, but I'm getting torn up with the color casts. I've heard that if I leave the lens out in sunlight it can help. Is there any other way? It's winter now.
It works great in black and white...
