8x vs. 10x Magnification

Eagle Optics,

Can you tell me what percentage of birders get magnification 10x vs 8x? They both seem really good. I have viewed your videos which are very helpful in demonstrating field of view, etc. Is it just a matter of personal choice?




It is mostly a matter of choice. I’d say the majority of birders use 8x.
A 10x is perfect if 1) you can hold that magnification steady (many people can’t), and 2) you are doing mostly long-distance viewing.

I would say in general 8x work well because they are very all-purpose as far as having a good mix of magnification and field of view. Most people will buy a spotting scope eventually if they need high magnification.

If you are a beginning birder or binocular user, I would also suggest an 8x binocular.

Interpupilary Distance Question

Dear Eagle Optics,

Can you tell me the name of the specification that describes how close the tubes can get on a pair of binoculars?

I have very close set eyes and can only use most binoculars as a telescope. My old pair of Minolta Activa 8x40 was almost what I needed but is finally falling apart after almost 10 years of really rough treatment. I'm a casual user and am looking to spend in the mid $300 range.



The term you’re looking for is IPD or interpupilary distance.

If you call your eye doctor, they will have your IPD measurement on file.http://www.blogger.com/img/blank.gif
If you give us your minimum IPD measurement and/or measure the IPD of the Minolta you own, we should be able to suggest some binoculars that might work for you.

When you measure your binocular, you can give us the measurement in millimeters from the center of one binocular eyepiece to the other.

Nikon Digiscoping Questions

Eagle Optics,

I have a question about digiscoping and pairing my scope with my camera.

Scope: Nikon Fieldscope ED III-A 60mm angled view with a 30x and 60x wide fixed eyepieces.

Cameras: Canon 60D SLR or Panasonic Lumix DMC-ZS5 point and shoot

Is it possible to pair either of these cameras with the scope for digiscoping? What adapters would I need?



Thanks for your interest in Eagle Optics.

Unfortunately, neither of your cameras will work for digiscoping at all.
Your 60 D won’t work because Nikon doesn’t make an adapter for the Fieldscope that will attach an SLR with its lens. Also, in order to use the body of an SLR without its lens, Nikon requires that the camera be a Nikon body on the Nikon scopes. Canons won’t attach at all.

Your point and shoot won’t work because of its high optical zoom of 12x.
In order to use a small-bodied point and shoot (the option you’ll want to go with) it needs to have no higher than a 4x optical zoom capability.

You could do a general google search or look at B&H. Nothing expensive is required, just a basic point and shoot with a low powered optical zoom.

Once you have a basic point and shoot, you can use this adapter or any other universal adapter.

Feel free to give a call with any questions as well; we’re happy to help!

Zeiss Diascope Digiscoping Setup

Eagle Optics,

I caught your offer for the green Zeiss 15-45x65 scope-sounds like a good deal. I think I may have got some stuff off you guys on ebay previously and I was recommended you by many folks who say you're the best. I was just wondering is there a digiscoping attachment for this device you may like.


Hi Duncan,

Thank you for your interest in Eagle Optics, and the Zeiss 15-45x65 spotting scope. It is definitely a great deal on a high quality scope package, and there are a couple of digiscoping adapters that will work with it.

The first is the Vortex Universal DCA for $59.99. It’s a very simple design, but will work with almost any Point-and-Shoot camera.

The other option is a Zeiss DCA for $455. This is a very well designed, although heavy, adapter that has several features the Vortex DCA does not, but the price is a bit of a pill to swallow.
