Question: Will this lens work with the EOS Rebel T1i?
Document: The purchased lens was mated with a Canon EOS Rebel XSi. When using the camera in automatic, indoor pictures are slightly under-exposed and pictures taken outdoors are slightly over-exposed. I have not evaluated the lens in any other mode other than automatic. Autofocus and image stabalization seem to work well.
I bought this to supplement the 18-55 lense that came with my Canon EOS Rebel T3 camera. For my purposes, it is a fine lense. I use it outdoors for bird and wildlife photography, and occasionally for shooting airplanes and trains. Very light and easy to use. The lense stabilization seems to work quite well.
My favorite lens for EOS Rebel T4i. Actually it's the lens I am using more than any of my other ones! I love it.
Bought this with my Canon EOS Rebel T2i as a package deal. A lens that performs as advertised. Would recommend it to anyone.
Purchased this with a Canon EOS Rebel T3 and takes really great pictures with the extra lens. Good deal and cant beat the price.
The camera lens, like the Canon EOS rebel T3, have excellent lens quality. The sharpness and detail missing in my last camera is present in this one.
I am a novice and this is enabling me to take really terrific pictures. I hope you enjoy yours as much as I am enjoying this lens with my EOS Rebel T4i!
This product came in bundle with Canon EOS Rebel T3i 18 MP.It was a very good deal.I used the lens for shooting distant objects and was always pleasantly surprised.It takes amazing pics.
I have been using this lens for a couple of weeks since purchasing it and have found it to be an excellent addition to my Canon Rebel EOS camera. It has brought me closer to what I taking pictures of with no apparent loss of image quality. Works well with the image stabilization and auto focus.
I bought this lens when I ordered myCanon EOS Rebel T2i 18 MP CMOS APS-C Digital SLR Camera with 3.0-Inch LCD and EF-S 18-55mm f/3.5-5.6 IS Lensand it has been worth every penny.
