I used my cat as a test subject and found that while both lenses captured subtle variations in color, the 24-70 f2.8 let you clearly see the individual hairs where as the f4 only showed tuffs of fur.<br /><br />Similarly, I did an image stabilization test and found that with my (fairly steady) hands, the sharpness from the IS f4 was equivalent to the sharpness of the free held f2.8 due to the difference in f stop between 2.8 and 4. This was with a low light shot where the exposures were 1/25 and 1/10 second respectively. While it's nice for environmental shots, any kind of movement gives the 2.8 a decided advantage in low light.AJ Hendersonhttp://www.ajhenderson.comnoreply@blogger.comtag:blogger.com,1999:blog-5826231802859523569.post-24233685908129429002012-09-14T05:10:05.882-07:002012-09-14T05:10:05.882-07:00When you get a chance compare it to the new Tamron...When you get a chance compare it to the new Tamron lens f/2.8 24 - 70 mm. It also has image stabilization. It's about one half the price. I 'm sure this is a fantastic lens but it is a bit pricey. Thanks again.bronxnlahttps://www.blogger.com/profile/17334931262193363831noreply@blogger.com
