I do a standardised focus speed test on the binos I review and I count how many turns it takes to refocus from a farmhouse I can see from my desk that is 2.5 miles away (pretty much infinity as far as birding is concerned) to a point in my office that is 2 metres away and Conquest HD 8x32 (a favourite of mine) does this in 0.5 turns. This is pretty quick and makes it great for getting on nearby dragonflies, then distant birds and then back close again for a butterfly or a nearby warbler. My Zeiss SF takes twice as long at 1.0 complete turn for the same distance and I prefer it for birding and other types of nature observation. Leica's Trinovid HD 8x32 at 0.70 turns is a good compromise between the two and it has a great short focus distance but lacks a little in field of view.
So there are alternatives out there that would give you different focusing characteristics.
