Probably<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" />I use a Swarovski80HD ats scope with a swarovski800mm adaptor, coupled to a Canon20D. I did buy a Canon40D to use with the scope because of the liveview feature which is found on many compacts, but the screen image was not good enough for focusing, much better to look through the view finder.Because of the camera sensor crop factor of 1.6, this gives me a basic 1290mm focal length, but I also use the Canon 1.4x extender when needed, giving over 1700mm.Pros :- Fraction of the price of a 600mm prime lens and 2x extenderDoubles up as a superb spotting scopeCan take pics at 800m+ if weather conditions are rightCons:- Has to be used with a tripod and remote releaseConstant f10Takes a few weeks to get used to focusing and following subjects$ prices are a lot lower than UK, so you would need to look them up yourself.UK comparison, I was going to buy a 600f4 Canon Lens at the time I bought the scope, lens price at the time £6400, 2x covertor £209.Scope, 800mm adaptor, stay on case, Manfrotto 055XPROB tripod, 808RC4 head, canon40d, remote release cable £3100.The scope will never give the IQ of the prime lens, but I am happy with the results, and I have a great spotting scope!</blockquote>
