Sometimes I have to or you won't see the bird. And you are right, I have an amazing lens. A bit too heavy but I have my tricks. Good for gaining muscles. Is that correct is it gaining?
My arms are stronger now then a while ago but not as strong as you think they are. It's hard to understand if you don't see me in action and feel how much effort and energy it takes to hold it like that for a few seconds. The pain and the shaking afterwords.
