Hi! Does the Nikkor 20/2.8 AIS need any special slim-profile filters or can I use the normal ones? Is it safe to use the 35/1.4 with a 62mm filter and an 52mm->62mm adapter (vignetting)? I suppose there should be few vignetting problems at 50mm focal lenght and further... Thanks... -- ............................//......................... .............. filip hajny // [EMAIL PROTECTED] ............ .................... http://yi.com/home/HajnyFilip .... .........................//............................
