Good Day People,

This is my second post after the introduction one

I will be travelling to my parents place in the next couple of months for a family fucntion ( Long story cut short, the function is sort of like a wedding), which will be indoors. I have got Sigma 18-200 OS, Canon kit lens, Canon 50 1.8, Canon 580 EX2 & the body is 400 D.

The question, is this gear gonna be suficent ? Should I consider any other lens ? At this stage, I dont want to dig in too much for a lens. I was considering a second hand 24-70 L f 2.8, but then cost was the issues. If I do need to get any lens, the max I can spend is $500 + or - 50. I have seen 85 f1.8 for sale (seond hand) around, but do i need it ? ( considering the whole affair is going to be indoors with family around) and would it be different to 50mm f1.8; i mean if i conver the 50 to 85mm by taking few steps, wouldnt that be same ?

Your advise is much appreciated.

Cheers.
