For $169, the 8x36 Sporter is a nice roof prism bin. Although there are other low priced roofs I prefer, I wouldn't hesitate to recommend the Sporter to any beginning birder seeking to get a decent bin, but not yet crazed enough to consider spending $1,000 or more. I recently was able to spend a little time comparing them to 8x32 Bushnell Legends and Celestron Nobles, as well as 8x42 Nobles. All were under $300.
Before I go any further, I know there are some very nice porros available and I did try to get the Nikon E2s for comparison. BUT FOR ME (eyeglasses and stubby hands), the better ergonomics of roofs vastly outweigh the benefits of porros. So pardon me if I don't genuflect towards the SEs. Besides, most beginners I get questions from, typically young 'uns and women, are in the same boat as me.
The Nikons overall had the most "pleasing" view. This is based on my perception that they were the warmest and had the most eye filling image. (The 8x42 Nobles in particular had a bit of "looking through a telescope" effect.) They also appeared to have the least amount of sharpness falloff as you move from the center to the edge. HOWEVER,...the Nikons were also the dimmest and least sharp of the 4. My "testing" was done with the dollar bill across the kitchen test, as well as some forest viewing during late afternoon - early evening.
The Sporters were the heaviest (25oz) and the armor was the least impressive; being the slickest and least durable. In fact, with probably the least handling of the 4 bins, the eyecups were pretty scuffed up and a couple tiny divots were taken out of the body armor. I figured they weren't returnable, so for now I'm keeping them as my car bin, unless I find somebody that will buy them. So beware! If you order a pair for demoing, put on your kid gloves! The Noble 8x42s got the most use and didn't show any marks. The Legends didn't either.
The focus could be somewhat stiff, but was the smoothest. They are not water/fogproof like the others.
The Eye Relief is so great that when the cups are fully retracted I got severe blackout. Twisting out the cups about 6-8mms did the trick. I'll have to make this permanent using some rubberbands. The 8x42 Nobles had the same problem, but not as severe. I would probably have to move the cups out about 2mm.
I know it may seem like I'm damning the Sporters with faint praise. But they are $60-$100 less than the other 3, and just might be an easier fit for the price point of an earnest beginner.
