Hi all,
Want some advise on teleconvertor 2x(sigma). I only find the technical specification but not any detail review.
What is the actual usage of it and who uses it. I more interested in snapping nature wildlife(bird watch). I have a 70-300 lens(Sigma), i guess is not long enough to take any wildlife. Can the teleconvertor boost the distance to 600mm?
Cheers
