Summary: I really didn't expect much from this lens for the price, but I am very pleased. It is manual everything, but get the focus and metering right and it's quite sharp. The photos were taken with a Nikon D3200 and monopod.
I have used this lense for reaching birds way out in santuaries and it does a nice job. I am pleased with it

Summary: This lense is ok as long as you use a tri-pod. without a tri-pod it would be almost impossible to focus.. I have used this lense for reaching birds way out in santuaries and it does a nice job. I am pleased with it. Just take your time with the lense and it will perform for you.
Summary: It is a fixed lenses (not programmable by camera). Used it to photograph the last lunar eclipse October 8th, 2014. Works great on my Canon T3 for sky, birds or nature. Very sharp, light and easy to carry. Great buy for the price.
