Apologies if there's an existing thread I should be adding to...
A few weeks ago, I posted somewhere on BF that IS bins aren't really suitable for birding. I said they were heavy and ungainly, and the image quality was not up to the best (or something along those lines). I also said I had little experience and was just remembering a pair of Canons I tried about 10 or 20 years ago and quickly dismissed – I stood to be corrected. I also noted that virtually no keen British birders use them.
I then asked around and got the responses I expected from my very experienced and capable birding mates:
# Too heavy…
# Make me feel sick…
# Ugly!
# etc
All except one who, it turns out, loves them. He’s a very well-respected and well-known British birder with an enviable pedigree – but I will keep his name back at this stage just because I’m prompting this post and not him (he was pretty laid back about this in fact).
So here’s his take on it, word for word - hope it's of interest:
“ Canon 10 x 42 L IS WP – a personal perspective
“ There are many high-end binoculars on the market – I have reviewed several of them for [website a] – and those that I have not I have actively looked through either at the BirdFair or when leading clients on tours for [company b]. However, for the past five years I have used Canon 10 x 42 L IS binoculars as my every-day binocular.
I never honestly thought about using these until I was leading a tour with [esteemed euro-birder c] in Morocco, when he told me to have a look though his, which I did and I was hooked. Through the image, with the IS turned on I was able to clearly see the emarginations on the wing of a Moroccan Blackbird that I could only just see with my Zeiss. They were amazing and for the rest of the tour I kept on nicking them off [c] to look through. When I got home I bought a pair and have not wanted to change since. [c] and I are amazed that so few birders seem to use them…
Looked through without the IS turned on these are already a pretty damned good optically (the L means that some of the glass is of the same quality as their very expensive lenses) – easily a match for most of the high-end binoculars on the market. However, with the IS turned on the image stills and the clarity has to be seen to be believed. A good test, which I often use to illustrate this to those that think they are just a ‘binocular brick’ is to put a piece of paper with fine and small print at c. 20 m distance (a bank note is good). Use a non IS pair then switch to the Canons: what the stillness of the image is able to do is to enable you to see the details much more clearly as it reduces or eradicates the shake. Any movement of your binoculars, no matter how good they are optically, degrades the quality of the image, so to remove it (or virtually so) is a major step. Imagine handholding a telescope compared with putting it on a tripod…
On moving objects such as raptors, the pressing of the button that turns the IS on has an enormous effect on the quality of the image you see. The bird is clear the image is smooth and the details observable far greater than with any binocular I have tested alongside them (even the very best). The fact they are 10x magnification is also important – I doubt I would choose a 10x non IS binocular due to the image shake, but on the Canon 10 x 42s that is more than compensated for by the IS.
I appreciate that they are not the best-looking pair of bins around and neither are they the lightest – they hang heavy on the neck during a long two weeks of touring – but I can’t do without them. I have found looking though leaves in a forest at, for example, Striped Wren-babbler the IS in having a still image makes the finding and watching of the bird easier – the leaves in front of the bird do not appear to be as distracting as they are not moving about as the bins shake a little – seeing the bird is easier and also with a stiller image any movement is likely to be the bird and not you!
I could go on for ages, but won’t. They have one or two downsides, I admit. They are heavy as I said, but perhaps no more so than the first pair of Swift Audubons I had as a boy. When used in hot temperatures with lots of heat haze, the IS seems to exaggerate the effect of the haze – this may be because you are seeing it more clearly. They are bulky and pressing the button to turn the IS on and off (clunk and click) when in a quiet setting or group might seem annoying at times. However, for me the benefits are so great that I cannot ever think about changing.
What I dream of is that Canon would improve the size and weight, yet still keep the high quality glass. I know there are new Canon IS bins about to be released, but the Canon 10 x 42 L IS WP binoculars will still be the yardstick against which they will be judged.
[I then asked about waterproofing…]
I have used mine incredibly heavily and have never had any moisture problems. I am aware that others have had issues, but mine have yet to let me down. You are also meant to get them serviced every 3 years, but neither myself nor [c] have ever done so. This can be pricey - I have heard costs of £500 bandied about, but not sure. At that price it is worth buying a new pair for £1000!
I do a lot of birding from my bike in [an English coastal county] and having cycled 10 miles or more, bins carried across my back, to have IS is essential. On boats they help with vibration but swell not so much.
