Internet searches and reviews are great for getting ideas and learning what to look out for, but there's nothing better than comparing several different models side by side for yourself. I can't tell you where the best places are in Toronto, but if you plan on going to Point Pelee anytime soon, Pelee Wings has an amazing range of binoculars and scopes that you can try.
I decided several years ago to upgrade to a better pair. I went to Pelee Wings fully expecting to spend over (and possibly well over) $1000. I came away with a $199 pair of Nikon "Action EX" porro prisms. I know that to be a "serious" birder you "need" a pair of roof prisms, but nothing less than Swarovski ELs felt comfortable in my hands. Sure the Swarovskis and a few of the other high end bins are noticeably better than mine, but not that much better that I was willing to pay more than 10 times as much.
I'm still very happy with my purchase. The only disappointment is the pair I replaced was only a few years old and had cost almost as much. I thought I'd done my homework that time, but I didn't have a good range of options to compare them to in the store.
Things to keep in mind when testing:
- take them outside - everything will look equally bad through a store window.
- compare both close and distant sharpness
- check the close focus distance
- how far do you have to turn the focus nob to go from closest to infinity?
- can you use them with gloves/mitts on?
- look for low light and shadow detail (most bins will look good in bright light)
- try them in the sun (some will look cloudy due to lens flare if the sun hits the objective (front) lens.)
- screw down eye cups are wonderful if the bins will be shared by eyeglass wearers and non eyeglass wearers
- Birds are more active on rainy days - waterproofness is a huge benefit
Finally, ask some other birders in the field if you can try looking through theirs. That's real field testing.
