Do I need separate tripods for my camera and my spotting scope?

Hi,
I'm a nature photographer and interested in digiscoping--so I'll be buying a spotting scope soon. Regarding a tripod, I have a pretty nice one for my camera.  Do spotting scopes require a different tripod?

Thanks,

Mike

Hi Mike,
Thanks for your good question!

You say you have a nice tripod for photography. The most important thing to determine is whether it is also suitable for your new spotting scope.  

No doubt the leg set, assuming it has an adequate weight capacity, will be fine (many digiscopers will buy carbon fiber, since it has less vibration than aluminum).  

It’s the tripod head you will need to evaluate for dual use. Here is our video which will help understand the differences in tripod heads: Choosing the Right Tripod Head

Let me know if you have further questions, and thanks!

Does larger aperture mean wider field of view?

Hello EO,
I plan to purchase either the Eagle Optics Ranger ED 8x32 Binocular or Eagle Optics Ranger ED 8x42 Binocular.  I was surprised that the Field of View for the 8x42 (341’/1000 yds) was less than the 8x32 (393’/1000 yds).  Why is that?  

Shouldn’t the wider objective lens of the 8x42 (42mm) give a broader field of view than the 8x32 (32mm)?  

Is there an advantage of one over the other?

Thank you very much.
David J.

 Dear David,
Thanks for your inquiry. It’s true that the shorter-barreled binoculars have a wider field of view (excluding compacts), though lots of people, like yourself, assume the opposite would be true. Field of view doesn’t increase with larger objective lens sizes. In fact, the Eagle Optics Ranger ED 10x50 Binocular has an even narrower field of view than the 42mm and 32mm Ranger ED.

You might find this video helpful for a more detailed explanation of aperture size, and  here is a brief article from our website to illustrate FOV.

The 32mm Ranger ED is the one to choose if you want a more lightweight binocular with wider FOV. However, it won’t be quite as bright in low light as the 42mm Ranger ED would.

Let me know if I may be of further assistance.

All the best,

Need smaller, lighter binocular for vacation

A friend recommended your online store to me.

I have a trip coming up to the Galapagos Islands and want to replace my binoculars.

My current pair is a 7X35 Nikon, 10 years old.  I like the wide field of vision, but they are a bit heavy.  Ideally I'd like better magnification, lighter weight, wide field of vision, good price.

Can you provide some recommendations?  I'd like to have the new ones at least two weeks in advance of my trip (which is in early February).


Thank you,

Jeana

Hi Jeana,
Thanks for your inquiry.  Do you know what the weight is of your current binoculars and do you have a budget in mind for the replacement pair?
I would recommend any consideration be waterproof.

One challenge with your request will be the wide field of view in conjunction with increased magnification.  Those two attributes almost always work against one another, meaning that as we increase magnification we generally get a narrower field of view.
 
In general, an 8x32 sounds like the ideal size binocular for you.  They will generally have a wide field of view and be relatively light weight while providing you with some additional magnification.  While 8x32’s generally have a wide field of view (compared to an 8x42), it’s unlikely that any will have one as wide as your 7x35.

Another advantage of an 8x32 is that there are many binoculars this size that have an excellent close focus, which is a great feature for observing the docile wildlife of the Galapogos Islands up close!
A good mid-priced option that is popular and would fit your needs is the  

If you had something else in mind or if I can be of further assistance, please don’t hesitate to email or call.
