looking to invest in a sigma 150-600 c , not sure i can justify splashing out £800+ so looking at used, now, im no expert but what should i be looking out for, dust, fungus ,wear, (daft question- how would i look for dust) ?
thanks dave
 
Dust you should see if you hold it up to the light and look through, you most likely will see some dust in a lens like this, it would have to be bad to spoil your images.
Fungus again you should see looking through it, no matter how small the amount walk away from it, wear can be a sign of use or abuse the less the better.
