Combined with a 20-50WA zoom this Swarovski HD scope is superb. Bright, easy to focus, reliable and sturdy and easy to clean and wipe moisture off. This scope is simply brilliant. Obviously one has to accept that its fairly big and heavy but its lighter than many of its size. Purchasing it is somewhat expensive but right now its in the top three scopes on the market and as good as there is for all round birding including seawatching and digiscoping.
