sorry i've been a bit busy lately... still enjoying the HUGE titanium M-Force.. it is the G-Shock of automatic watch.. this watch is my current fav since it just build so well and run really great.. it is the kind of watch that build to last a lifetime..
Ive been using the cokin filter holder and various filters for probably 20+ years. Lots of choices with that system and not that expensive. ND filters are great for blocking light to get slow shutter speeds.
