Binoculars: Canon 12x36 IS II and 15x50 IS review

Hi.

I wrote a review and made a youtube video of the Canon 12x36 IS II and 15x50 IS incase anyone's interested.

nice work

I own a pair of the 12 x 36 IS and previously owned the 18 x 50 IS and the review pretty much nails them. Incidentally, the Camera Warehouse link in the review doesn't work.

Thanks, I updated the link...

What did you think of the 18x50's?

I initially bought the 12x36's and then figured maybe the larger objective, 20% increase in magnification, tripod mount and UD lenses would yield a significant improvement; that coupled with the views on http://www.cloudynights.com made me go with the 15x50's.

If I had known there was so little difference in magnification between the 12x36's and the 15x50's I may have opted for the 18x50's.

I guess at some stage I'll put the 12x36's on eBay, as the wife has shown 0 interest.

The magnification of the 18 x 50 IS is noticeably much greater than the 12 x 36's, which overcomes an issue mentioned in the review. They're heavy though (like the 15x) and if you have to tripod-mount them, I don't see much point in paying for the IS feature.

The IS in the 18x seems less effective than in the 12x - maybe it's just my spindly arms and the heavier weight. I find the 12x easy and comfortable to use - by day or at night - and the IS is rock-solid, whereas the 18x was much more tiring for me to hold (especially pointing upward at the stars), and the IS didn't eliminate all movement.

Did you notice any CA with the 18x50's? Both the 12's and 15's exhibit a little... it's very slight but it present.

Did you measure the close focus distance?

I don't understand why the 18's are ~ 15% more expensive, when it appears there should be no difference in manufacturing expense.

Looking at Jupiter, were you able to discern any bands?
We've still got a couple months before Saturn is visible again... did you happen to look at it with the 18's?

Looking at small faint objects, I also find the IS with both doesn't eliminate the shake 100%, but it sure helps a lot... goes from a shake to a sway.

Same for the 18x

Did you measure the close focus distance?

I don't take any interest in close focussing with conventional binos - too much eyestrain, my eyeballs need recollimating afterwards! I use 6.5x Pentax Papilios when I'm in the field chasing orchids, fungi, butterflies and other close targets: perfect.

I believe the 18x and 15x are physically identical apart from the eyepiece magnification factor - you're right, nothing realistically justifies the surcharge.

No Jupiter bands - my aging eyes aren't that good and Saturn just looked like a mis-shapen small yellow blob to me.
