664 or 77?
I realize that digiscoping will not give me the same results as my Canon and L series lens but will allow me to digiscope for fun, bird ID etc.
Given that.....would it be better to get TSN 664 with ED glass or a 77mm with standard glass in your opinion? I have just purchased the TSN 664 ED glass but it has not been shipped nd yet I keep thinking I should have ordered the larger 77mm even though it has no ED glass. (Recognizing that digiscoping is on the side, not my main attraction)....jim
For photography, ED gives better pics at all magnifications. Go with the 664 for digiscoping.
