Whenever I go out looking for critters I always have my TC-17eII in my pocket or on the camera itself. This is especially true with birds. Often times when working with such small subjects that tend to be far away, so you tend to need that extra reach. The downside with a teleconverter is that you add a joint in between the camera and the lens. This makes it less stable and more prone to vibration from your hand leading up to potentially fuzzy images. Plus if the subject moves then it becomes really hard to get a tack sharp images. The TC-20eII is a 2x magnifier and is a really great tool for working with birds but for that stability reason I rarely use mine. Well this is the one case where I wish I had it.
This Pied Billed Grebe was a bloody rock. There was one spot where he liked to sit and outside from a little feeding he was always there. If there was a time where having a little bit more glass would’ve been nice it would’ve been here. While I don’t always like the portrait shot all the time, I go for them when the opportunity arises.
