Been using my 8800 for a few months now for all type of pics, lots of them for birds at close range.
I use the 5mb setting and can take pics of birds "hopping from twig to twig" as fast as the bird settles. The digi zoom gives good results up to 2x (gives me a 20x zoom) hand held, even at 4x in poor light it gives reasonable ID pics
The 8800 is NOT slow, it just slows down when using the 8mb setting, but that is common to all cameras isn't it? when "chasing birds" i either use a manual setting for focus or simple prefocuss by pressing the shutter halfway....this allows you to wait for the bird to pose and is virtually instantaneous.
The 1.7 converter attaches via an adaptor screwed direct to the body.
Remote...upgrade to the version 1.7 and you can set the timer on 3 secs and take as many pics with the remote as you want without having to reset.
I have purchased a "cheap" Kenco 3x converter lens and it is US with any combination of camera settings.
Is "Speed" really a problem?, I have fiddled a bit with scopes and simply getting the bird to keep still long enough is surely the real problem, you only need one shot don't you? or do you want a camera that takes a load in one burst and hope to get a good one? Not my idea of photography.
Look, compose and take pic.
