Canon 2421U50 12 x 36 IS III Binoculars

Product Information

The Canon 12x36 IS III binoculars would be best suited to observers who already use a telescope or larger binoculars as their main instrument, but also want a single multi-purpose instrument.

Thank you all for all your kind help, may I wish you all a very Happy Christmas and a Wonderful New Year. Both binoculars have decent ridged baffle tubes and very good multi-coatings. You can peer into the binoculars with a torch without undue glare. For aircraft, words written on the side, even the colour of letters appear where no marking was seen at all with the IS off. But brighter objects show a lot of problems. There seems to be some astigmatism and lots of CA. All I saw of Mars was a colorful irregular shaped blob.

The binoculars use the compact Porro Type II prism system. This cemented system has several advantages over the more common Porro Type I prisms: as well as allowing a greater interpupillary distance range, it offers increased light transmission and fewer surfaces where chromatic dispersion, light scatter and spurious reflections can occur. Objective lens focusing Price relativities between the various models are bit different here in Australia. When available, the 12x32 is almost twice as expensive as the 12x36. The price of the latter is much the same here as with b&h (FX fluctuations notwithstanding). So in the full context of a purchasing decision here in OZ I feel it is hands down in favour of the 12x36iii.

I am very happy with them and they are staying here. Their close focus is something I've longed desired. Comparisons with the 12x36 IIs, both on my feeder birds and my dollar bill target show they are quite comparable to the 12x36. I've always been happy with the IS on the 12x36 and never had any issues. If anything the 12x32s are a bit better. Ditto for the optics. Color fringing is only visible near the edge of the field - almost certainly lateral color in the eyepieces. It's properly symmetrical. There is some color if they are not quite focused, but it's easy to get a precise focus. I had a chance to compare these for 3 days under various conditions and these are my somewhat subjective findings given the 12x36 III are half the price. Both were made this year and new in box when tested. The technology of image stabilisation is undergoing continual improvement so we hoped for great things from the latest incarnation of Canon’s 12x36 IS binoculars – and we weren’t disappointed. We can certainly afford the repair. I’m just not sure it’s the best use of our money and I hate feeling ripped off. But I don’t really like using duct tape and “giving up,” either. I've read many criticism regarding the eyecups, and I agree that they're not the best parts of the binoculars. It must be said that, at least in my case, I can see the entire FOV without much problem (I don't wear spectacles). I would have preferred a more contemporary multiple-step twist-up design that allowed the viewer to achieve his or her perfect viewing position.Image stabilisation is powered by two AA batteries, with a specified life of nine hours at 25°C, falling to one hour at –10°C. These batteries are readily available, so you would be very unlikely to be caught out in a situation where they have run out of power and you could not source a replacement. Good interpupillary distance range The battery cover of my Canon 12x36 IS III binoculars broke a few weeks ago. This made the image stabilization temporarily nonfunctional.

Although the PST H alpha solar scope was set up permanently on a Slik 88 tripod for about 15 years, although I don't use it much lately. The prism system is a Porro Type II, which means that you adjust the interpupillary distance by rotating the entire eyepiece assemblies.But yes, you can read fine print and number plates that you simply cannot read with a non-IS unsupported 8x or 10x (let alone an 12x, at least in my case with my hands). At this time of year deer come into my garden at dusk to eat the fallen apples. The 12x are not good twilight binoculars. My 2015 Leica 10x42 ,despite not being the brightest, are much better. The 10x seem to have the edge on the Leica optically everywhere apart from colour fidelity and veiling glare. The Canon 10x are touch to yellow for my taste the 12x a bit cooler. But I do agree that the eyecups, when raised, are bad. Folded down for use with my glasses, which is always the case, I like them better than the eyecups on the 12x36s.
