If they were the same price (which they aren't) I'd get the Century but only because I find I could sometimes use some extra zoom. Ok, you can almost never have enough zoom in wildlife photography...

How much more zoom do you get with the Century?

check the specs but i think its .3x more right? (from a 1.7 to a 2.0)

A better way of looking at it is in 35mm equivalents. The equivalents for the standard 20x is 40mm - 790mm (per B&H catalog). So, 790 mm is about the same as 16x power binoculars (15.8).

Using the Sony, 1.7x, gives you about 1300mm (27x scope)

Using the Century Optics 2.0x, gives about 1580mm (32x scope)

So the 0.3x difference translates into an additional focal length equivalent of more than 200mm and a magnification incease of an additional 5x.

Assumptions - the conversion factor of camera focal length to 35mm is 9.4x; multiply the additional magnification (i.e., 1.7x) times the focal length (84mm) times 9.4. To calculate binocular/spotting scope equivalent magnifiaction divide by 50.

Thanks! That helps.

I have the Century Optics 2X teleconverter and I am very happy with it. Quality is excellent. The quick on/ off bayonet mount is much faster and easier to attach compared to a screw in mount.

Either way you go, you need a good tripod!

Steve Nunez, nice Red-Tailed shots. Looks like a nice Bob White quail dinner.
