I currently have a Sigma 17-70mm behind an 8" dome port. I will be heading to Lembeh to shoot little critters and I am trying to decide if my current lens and dome will be OK, or if it would be worth getting a Canon 60mm and a flat port. On one hand the 60mm is a shorter lens, but the flat port gives some maginification; on the other hand, the 70mm is longer, but no magnification behind the dome port.
Do you have any of these lens/port configuration? What is your recommendation
Thanks in advance for your comments
