Hi there,
I have been testing the Tokina 28-70 Pro SV for 2 weeks. I got two lenses, first one with front focusing so I returned it. The second one does have front focusing about 2cm, but the target is within focus range so I accept it.
Later on, when I did the real world testing, I found there are severe chromatic aberrations all over the picture. I am so disappointed! I can't figure out how this lense rated so high in photonet and photozone. This lense looks like a piece of junk, I want to sell it right away(I can't return it since it has passed 2 weeks since I received it).
I then removed the protecting filter, took some shots, checked the pictures, and guess what? there's no chromatic aberrations! I put it on, there comes chromatic aberrations! With filter on, I also found that there are severe glare when pointed toward sun. It is really annoying! The filter I use is HOYA HMC SUPER.
I need your advise about this- Do I need a filter(for protective)? If so, what is the best filter that is affordable?
Thanks
