New toys... compensating for my small car.
1.6x crop sensor x 1.4TC x 2TC x 400mm = 1792mm.
With today's arrival of the 2x teleconverter, I can now achieve a total of 1792mm focal reach in 35mm equivalent terms. Looking forward to some clear night skies and a full moon.
Gear featured includes the Canon 7D, the Canon EF 1.4x III teleconverter, the Canon EF 2x II teleconverter, Canon EF 400mm f/5.6 L USM. I also have a little bean-filled neck pillow which I find is an awesome stabiliser for resting the camera on things like car bonnets, fence posts, safety railings, etc. And yes that is a Nikon strap. It makes the world of difference to my image quality.
(Edit: I now prefer the 60D for this setup, as live-view on the flip/swivel screen makes life SO MUCH easier for things like moon shots).
I'm aware this combo (especially while stacking teleconverters) will make a big dent in my image quality and lower my maximum aperture waaaaay down, but for moonshots in particular I think the benefit of increased focal length will outweigh the disadvantage of reduced quality when viewed at 100%. And I bought this lens mainly for FUN as opposed to being a breadwinner. It's easy to forget about the FUN factor after taking photos all day, every day, as a job.
One day I'll own a 400mm f/2.8 :D
PS.- After a few evenings meddling with this setup while taking shots of the moon and Jupiter, I think I'm going to need a bigger tripod. Even merely *touching* the focus ring will send trembles through the lens that take 20 seconds to subside. In these situations, a shutter cable is absolutely imperative.
