Outstanding lens for the money. Let me clarify, this is an outstanding lens if you know how to use it. Everything is manual and you need to take some time to learn to use it properly. First, it is a very slow lens (F/16 at 1300mm or F/32 with the teleconverter. Given that Canon's equivalent focal length all automatic F/5.4 lens is custom built for $99,000, this lens is a steal. But you do need lots of light and/or a sturdy tripod. Biggest drawback (besides the aperture limitations) is that the lens tube is somewhat flimsy at the longer zooms. I felt it could be a bit sturdier and this is why I give it a 4. There is also a bit of chromatic abberation at long zooms in bright sunlight. Still I was able to see and photograph Saturn's rings at 2600mm ( I wish I could post the photo here). Moon photos are amazing and, with a solar filter, you can see and photograph sun spots. I am extremely happy with this lens.
