<p>"...cannot produce an image thaz sharp enuf to justify mounting such lens on a 10 year old 12MP digital camera, crop or FF"</p> <p>Thanks for your colourful response Golem ; ) and point taken. Full-frame is the only way to properly evaluate a full frame lens. However, re: your "10 year old" comment, are you thinking I have a D60 instead of a 60D?</p> <p>THX D</p>

<p>Thanks all...Rick/John, you raise a good point and will retest at varying apertures.<br /> Puppy, I wouldn't be surprised if it could use some tweaking given its' age, I don't know much about what can be done but may have someone look it over.<br /> Peter, I also agree with you that the kit lens might just be better than we give credit...or maybe I happen to have gotten a really good copy!<br /> I admit I have done some commercial shooting with my 18-200, out of necessity, and while it's a slow, noisy beast the images (esp. when shooting with flash and the lens is closed down) look pretty good with a little post work.<br /> My goal in buying the L was to have a faster lens and hopefully help me cut down on the amount of post work needed...we'll see how that goes.<br /> THANKS D</p> <p> </p>

<p>Hi all....just bought a second hand EF24-70mm f/2.8L USM. Serial number indicates it was manufactured in 2005. It's feels good and looks well taken care of.<br /> I thought I'd compare it to the lens I got with my 60D, the EF-S18-200mm f/3.5-5.6 IS.<br /> I set up a very quick test...shot the same scene once with each lens both shots at 40/43mm (I eyeballed the zoom setting for the kit lens so it's off by 3mm), 1/160, f11, iso 100, studio flash with my 60D.<br /> Well, these crops seem to tell me there's virtually no difference between the two lenses...in fact I'd give the edge to the kit lens!<br /> I know a lens is about more than image quality...it's also about build and other factors (the 24-70 being faster and constant aperture for instance) but I was kind of expecting at least a mildly notable jump in image quality. Am I off base in my thinking?<br /> If you'd like to see my test, here it is...full shot provided for reference, the crops are full size.<br /> I'd welcome any wisdom/thoughts on the matter. Thanks, D<br> Image here (I hope it can be viewed full size)<br> http://imgur.com/DKJhESV</p>
