Hi,
Sorry if this is a bit off topic and possibly discussed already, but I figured most who are into birding are going to know at least a little about binoculars. I know there's a lot of information elsewhere, especially on birding sites which aren't focused just on photography, but some of the specs are a little overwhelming to me. I'm hoping to just cut to the chase and get some honest opinions on what to look at for budget binoculars and how much I need to spend for decent results.
I'm very new to bird photography but enjoying it and hoping to learn more. I'm now using a 400mm f5.6 on a crop sensor and I was looking for binoculars to also carry along with a higher magnification than the lens has but I don't know how the "mm" on a lens correlates to the "10x", "12x", etc in the binocular specs. I found brief discussion of this searching online and it appears I would need 12x or 13x to match the magnification of the lens, is that about correct? And then my next question would have to be, if I'm only getting about the same magnification, is there even a reason to bother carrying binoculars too or am I just as well off looking through the camera lens?
I'm hoping to spend around $100 or so but with what little I know so far, I'm not sure if I can get away with spending less or if I need to wait and stretch the budget further.
Also, do most of you use spotting scopes or binoculars to sight up the birds first or just start straight-out looking through the camera lens once you find a spot to watch from?
thanks for any insight on the topic and sorry for the convoluted questions...
