I have a Canon 50D and 400/5.6 which is my main bird lens. I use a Manfrotto CF tripod and Kirk BH-3 head. I am debating whether to upgrade to a Sidekick or Jobu Jr. gimbal head, or stay with the Kirk. I can't handhold the 400 since I have a slight tremor. I know the Mongoose 2.3a is the head of choice - but is no longer produced.
Is the purchase of a gimbal for this setup overkill, or a good idea? I doubt, because of cost, that I will upgrade lenses anytime soon. Thanks.
