Cheap telephoto lens

[dupek]

I know, I made booobbooo when I purchase cheap 500mm telephoto lens made by Phoenix.
I am getting purple hallo around objects. Is that the glass or I am doing something wrong.
Thanks.

Nope its the glass.

Its the glass. Software can get rid of some of it, deppending on how bad. But in general get what you pay for. If you want to learn more. Look up Chromatic Aberration (CA).

You pretty much got what you paid for.... a paperweight.

I did another series of testing with 2X converter attach. No more "purple fringes". I guess, the 500mm have wrong focal point. The problem I am getting is the manual focus. Even with "good glass", I am getting bad focus in manual. My eyes are going bad.
