Hello, I would like to invest on a new lens for spotting. I'm confused between Canon 70-200 F4L ii IS or Tamron 70-200 F2.8 VC G2. I'm wondering if F2.8 is really necessary for night photography, but at the same time I rarely did a night spotting. And for years I would like to own a Canon L lens, anyone can help me make my decision of saying which is the better choice and why? Thanks

It dépends what you are callin night spotting.
If you're talking about dusk , when the light is going down, then you may need an aperture like f/2.8, but remember: the greater is the aperture value, the lesser is the deep of field. You'd better go for a DSLR wih high iso capability.
If you're talking about complete night, then the is no need of a great aperture: the recipe for night photo is simple: tripod, 100iso and several seconds for the exposure time.

My only truly night shoot was at RAF Northolt. I used a good solid tripod, aperture priority, ISO 100 and f8. A remote Bluetooth shutter release ensured no camera shake. Lens was a Nikon 18-135 but lens choice really comes down to the zoom range that you require.

But if the aircraft is stationary, than i would use about f/8 and iso 200 or so. And let the camera decide what my SS is.

It depends on the circumstances. At 2.8 your depth of field becomes small and depending on the distance between you and the subject, parts of the plane might be out of focus. So for non-moving subjects a tripod and F8 is preferable.
If we are talking about moving subjects 2.8 gives you more light and allows you to either have a faster shutter time or use a lower ISO setting.
