$$$ and weight loh.buying cannon for canon arh? never heard of mirror lens with AF. this kind of lens prob have to do special order. in which case why not get the 300-800 sigmonster?
I'm tinkin of getting something around 800mm or more mirror lens, EF mount.
Anywhere to get it locally?
Also, 1 question. Is there such thing as AF for mirror lens?
thanks, I'll go check it out.Culés;3038141 said:I saw a new kind of mirror lens (at least I never saw it before) a Tokina 600mm, at Orient Photo at Sim Lim, said $600 IIRC, if that is indeed a new gen, maybe it has AF? check it out.
actually.. cheap and light.depends how much $$ u want to throw in and how strong is your tripod...
4000mm f8 enough? around 90kg only
retail at US$40,000
not sure if we are refering to the same 4000mm, cuz I tot scopes are references are more of fov and magnification.My 1200mm already can see Venus n Mars liao ... 4000mm sure can see a lot more (if you are using a good eyepiece) ... I can even see Jupiter n Saturn easily ...
but the carrying out and setting up is a bit sian ;p
