Ok while not strictly a telescope it approaches the size of one and for those of us with family and other things sometimes a quick snap is all we get. As an aside I purchased this lense more so for closeups of the Sunset and rise as well as for quick snaps of the moon.I have it on a 60D with a 1.4 sigma extender and yes auto focus still works but not super fast.I have also added a Uv filter and a Circular Polarizer. At 95mm aperture these are not cheap $250 & $350 respectively from Sigma(Made in Japan)
The lense is made in China but the lense hood in the Phillipines(go figure) and its cost was $1350 from Camera House. So far I have not taken many pics of course the clouds and rain have arrived my fault.
I have noticed a blue tinge when used with the Extender on the moon.
As I take more shots I'll post them in the terrestrial Section .
Below I will add some pics of the set up and its comparative size to my previous 400mm.The 65% greater light gathering capability is a plus despite its f6.3 at maximum length.
Also a pic taken with it.
Cheers Derek
