So here’s one of my first tries with the HiTech filter system (similar to Cokin, Lee etc). ….. and my first set of shots after nearly a month of not being able to get time to shoot.
I ran into a little trouble with it on my 10-20 and other lenses – light seepage – light seems to enter between the gap formed by the front element and the filter holder and bounces around inbetween causing ghostly reflections (and in some cases perfect reflections of my front element) – could do with some advice on how to deal with it (here, I dealt with it by shooting with my back to the sun as far as possible – and blocking the gaps with my fingers)
Sigma 10-20 at 15mm (it vignettes a bit even after I sawed off the front two holders – so forced to use 12mm and above)
