I don't have the wired remote but was told that it has a button lock so u dont need to hold press for a long time. I have the wireless though but havn't tried bulb (cuz I didnt knot it works with it). Will try it out.. tnx for the info =)
For a cheap macro lens alternative, i'd recoment 50mm F1.8 + entension tube combo. You'll spend about S$300 (brand new). Try to buy a used lens if u can find one on sale.
