Hi
What is a good choice for a first pair of bino's for birdwatching under £100 lightweight as i cycle and walk, I want something compact. I like the look of the papilio's but I know very little about this kind of thing, and i get the impression they are more for looking at things close by ? I would like something that would allow my to see some distance away..
Thanks
Are you able to go to a shop to try some models out? The Papilio is really neat for what it does, but there are two models, each of which is unique, but a different compromise for birding. The Papilio is a reverse porro design, which is more compact than a conventional porro but not as compact as equivalent roof prisms. However, reverse porros can be an incredible value due to optics quality , as compared to spending the same money for equivalent roof prisms, which apparently require a much greater expenditure to get equivalent performance.
The 6.5x and 8x will be fine for anything from close up to infinity focus. They Papilio (latin for Butterfly, I believe) is designed to allow very close focus for butterfly, dragonfly, and even flora uses (kinda like a microscope) , while also being fully functional as a binocular. I'm sure there's plenty of other uses. I don't know if they ship over the pond, but the US-based cameralandny.com has very good deals.
For birding use, I like an 8x binocular, 7x being acceptable. The 6.5x will have a nice, bright image for most uses with >3mm exit pupil, as well as being very easy to hold stable. The 8x will have about a 2.5 mm exit pupil and will thus be less useful in darker days or dusk/dawn. Think a bright image doesn't matter during the day? Try viewing a very heavily backlit subject. A heavily shaded area is also a challenge. This will also test the "brightness" of a binocular in mid-day.
Personally, I'd keep my eyes open for an 8x25 model (Opticron?) but for the price, the Papilio is great. Try before you buy is the best situation but understandably not always possible. If I were to pick a Papilio as an only binocular, I would go for the 6.5.
Have fun.
