Can somebody give me advice about which binoculars i should?

You are very welcome.

Thanks for all your reply! No matter what kind of things I like to buy, what I need is I love it. So I don't mind whether Eyeskey company is small or big. I just want to get my favorite [link=http://www.opticsplanet.com/binoculars.html]binoculars[/link] with good quality.

Seems to be a smaller company
http://www.eyeskey.com/
and nothing amazing there.

Look thru mahor brands here, [link=http://www.opticsplanet.com/vortex-brand.html]Vortex[/link] and [link=http://www.opticsplanet.com/alpen-brand.html]Alpen[/link] have low price binos that are at least phase coated.

Note that mail order binos can be returned if not happy with what you got. You do not have to buy from a store if they only have Eyskey and one other brand.

Hi

There is more to [link=http://www.opticsplanet.com/binbirds.html]birding binoculars[/link] than just the specs. You also have to consider [link=http://www.OpticsPlanet.Com]optical[/link] and mechanical quality and subjective factors such as handling - that can be quite important if you bird for long periods at a time. Then, too, even within a single brand like [link=http://www.opticsplanet.com/leupold-brand.html]Leupold[/link], there is quite a difference in [link=http://www.OpticsPlanet.Com]optical[/link] and mechanical quality, depending on the model you choose and you did not specify a model. I am not familiar with Esky, however.

If we only consider the specs you have provided, the only significant difference is in the field of view. If you are a beginning or even intermediate birder doing close range work on warblers and other song birds, the wider field of view of the Esky is an advantage. If you have been using [link=http://www.opticsplanet.com/binoculars.html]binoculars[/link] for a long time or you are typically doing mid-range or long range work on birds, field of view is less an issue.

Last week I like two [link=http://www.opticsplanet.com/binoculars.html]binoculars[/link] Eyeskey 10x42 and [link=http://www.opticsplanet.com/leupold-brand.html]Leupold[/link] 10x42 the same time, but I can only buy one, I use it to birding, so can somebody tell me which I can buy?
Thanks.
