I have taken a lot of pictures through my Zeiss with the camera on my phone and the pictures are surprisingly good.Aron,
One more question on the camera/spotter set-up. Do you ever take pictures through the spotter? Or do you just use the 210mm lens you speak about?
Except digiscoping can get you much longer focal lengths. Also, some digiscoping setups can provide surprisingly good photos. Also quality DSLR lenses over 500mm are prohibitively expensive and HUGE.For the best wildlife photos a DSLR with dedicated lens will always beat digiscoping. I have been using 35mm equivalent 510mm and 750mm lenses on a DSLR with good success.
