Hi,
I have recently been given a Vanguard Endeavour HD82A spotting scope and I want to try digiscoping with it. Currently I have 3 Nikon bodies D7000, D3000 and D60. The standard 18-55mm gives a black ring when using the PA 202 adapter and doesn't work in AF mode unless I use the D7000 with the camera body AF/M switch set to M.
Does a low F number lens work on AF?
Can this black ring be avoided?
If not, would I be better off with a prime lens?
Can anyone recommend a lens for one of my existing bodies, probably the D60 as my wife uses the D3000 and I use the D7000 with my Sigma 150-500mm?
What is the maximum step up/step down combination that works without the black circle?
And finally, sorry for so many questions, (but I need advice not an attempt at a sale that I get elsewhere) my Sigma 150 -500 mm would need an 86 mm- 58mm step down set. If such a set exists, would it be practical or still leave a black ring around the photo?
Many thanks for your patience.
