He was determined to love this objective on the basis of specifications and price. Canon really needs to go with this objective in this price as a lens that offers Nikon's Vibration Reduction in very decent about it for the same price range, leaving me to make excuses for Canon and their contempt for all Nikon friends.
The IS can be turned off to save power, but I have not noticed a difference in battery performance with him. The SE is only activated when you press the shutter button. Although there seems to be a small delay for the IS to start, I think I have no photos, because of confusing.
You may hear the IS. A bit strange after using point and shoots I have is that it does not say anything, but there seems to affect performance
Pro: Great price for a zoom lens, image stabilizer. I paid 299 and am very happy, although Amazon is selling for 280 a week later. Also arriving two months earlier than originally promised Amazon. This goal was never $ 400. The price before the release of the Canon was 299.00. Amazon shame!
Pro: The images are very sharp.
Pro: Image stabilization is a very good job. Four stops as announced by Canon? I'm not so sure. Greatly improving the experience of the composition of 250 mm? Of course.
Pro: much smaller and lighter than the 70-300 from any manufacturer and much sharper than my Sigma 70-300.
Cons: feel modest. But only use it, but feel now. Plastic construction. But if you need a lot of metal, I suggest being a little hard on your camera. * UPDATE * The plastic tabs on the back were able to hold the camera firmly on the goal, but they are firmly back cover of the lens. I tried various rear lens caps to fit other lenses. So I think it is beyond economic sense and must be called to build cheap.
Cons: This lens is a little (well, maybe not so little) slow to focus in low light, sometimes lost when I think of the other goals of mine would have no difficulty.
Cons: I never thought much internal focus on my other lenses until I used it. The front of the lens rotates and moves in and out a lot when focusing, so much so that even may want to compose your shot. The length of this lens changes almost an inch throughout the focusing range. I just checked my Sigma 70-300 and found that it too, but I never saw him make a big difference on the screen as I have with this canon. Your perception may vary.
This aim and hasten the XSi 18-55 IS kit lens lens allows me to get a lower 18-250 is range. For a little more money than the cost of the lenses can get Tamrom 18-250, but no image stabilization. And now you have a Sigma 18-200 with optical stabilization of these two lenses of lower cost, but the proof of Canons 2 produced better images.
Conclusion: The EF-S ideal for users of Canon. (Although Nikon Canon had to push to do it for us.)
