first of all, thanks PBPF for allowing me join this forum. Im a beginner "birder"and would like to learn a lot from the Pros. just came across this website accidentally and was really amazed with the tons of information available.
btw, Im max de leon, a filipino, now based in Austria and will be starting this hobby very soon, once I get hold of my long lens (most likely on wednesday).
Hi Max, welcome to the forum! We're glad that we will be having a member at that part of the world. If you have questions about bird photography and/or equipment, please feel free to ask. We'd be happy to help.
thanks Sir Bob. probably one question on converters/extenders, canon 2x, is it worth buying this one? ill be putting this one on my 100-400mm, along with my 40D. Ive read that i'll be manually focusing using it but im more concern on the image quality. will i sacrifice a lot of image quality using the extender?
sorry for this quesiton, maybe this has been answered before. havent browsed the whole forum. but im doing that right now. =)
Hi Max. Welcome to the forum. You must be so excited to try out your "long lens" when it arrives.
I don't own a 100-400 lens but I find that having the 2x and 1.4x TC available helps a lot when you need them. Right now the 1.4x TC goes well with my 500mm + 5DMK3 and I am still very happy with the image quality.
I do have a 400mm paired with a 40D and I am happiest when I don't use any TC on the combo. I sometimes use a 1.4 TC when I REALLY, REALLY need more reach but as much as possible I try to avoid them.
I really hope the owners of the 100-400mm will be able to help you out with your query.
Welcome to the forum, Max. Hope to see bird photos from your side of the world.
I don't have the 100-400. I have the 400 prime and while I agree IQ will take a hit, I wouldn't hesitate slapping a 2x TC if the situation demands it. The potential increase in the amount of detail captured due to the increased magnification can somehow offset the loss of IQ (not accounting for other abberations). This applies to situations wherein you are focal-length limited like shooting the moon or a bird too far for a bare 400mm to resolve enough detail.
That said, I try to avoid using a 2x as much as I can.
