		Hello,
 
 I'm looking to upgrade to either the Canon 40D or the 50D and I am wondering if there's any point in getting the 50D given my lenses. I am shooting with a Sigma 10-20mm 4-5.6, a Canon 28-135mm IS 3.5-5.6, and the Canon 50mm 1.8 II. I'm not going to upgrade my lenses anytime soon so my question is:
 
 will the extra resolving power of the 50D be wasted on my lenses? At what point do my lenses become the limiting factor in image quality? 
 
 Thanks,
 
 Jesse |

		The 50D is superior to the 40D regardless of what lenses you own, specifically due to the 50D's ability to store multiple lens micro-adjustments.  The process isn't too difficult (I posted about it in another thread that I'll try to find later).
 
 Basically, you run each lens through a test and adjust it for optimum performance.  The camera stores these settings for up to 20 different lenses and applies them whenever you use that lens.

		To the OP...probably not worth it with those lenses but will you buy better lenses down the track ?

 Out of curiosity, hHow many of your lenses required adjustments ?
 
 I have the same feature on my K20D and none of my lenses needed adjusting which makes the feature worthless.

 Of my four lenses, all but one needed adjustment.  None of the adjustments was more than a few points, but still, I find it to be a very useful feature.  Anything that helps get the most out of lens is worth it, IMO.

 Thanks for the reply...
 
 I agree completely. No point buying good lenses if they don't work as they should.  
 
 Of interest to me is that 75% of your lenses required focus adjustment.  I hope thats not the norm for Canon as it pretty poor for those using bodies without MFA.

 I wasn't surprised myself - anyplace that makes hundreds or thousands of lenses in a year will have some variation between each one.  I'm not reading too much into this, but the only lens that didn't require adjustment was my Canon 28-135mm.  Each of my third-party lenses required the following:
 
 Tokina 10-17mm fisheye: +3
 Tamron 28-75mm : -1
 Sigma 70-200mm: -1
 Sigma 70-200mm w. 2x TC: +1
 
 An adjustment of 1 is very slight.  And as far as the Tokina goes, it's such a wide angle that I can forget to turn the AF on and everything is usually still in focus (the focus indicators say so), so I figure a +3 adjustment there isn't a big deal, either.

		Can micro adjustments even be done with the 40D, and if so is there good tutorial on site someplace?

		You may want to get yourself a 40D. It seems that the IQ, especially at higher ISO, is better than the 50D. There are some nice features with the 50D, but not for an extra $400 IMO. I'm planning on a second body, likely the 40D which I've owned already. Great camera.

 Canon can do it for you. It's not a user controlled feature. |
