<p>I know of no exception to the rule that the most open aperture maximum (f/3.5) will be at the shortest focal length (in the case at 15mm), and the smallest aperture will be the maximum at the longest (f/5.6 at 85mm)<strong>.</strong></p>

<p>OK, thank you JDM. I guess my current lenses all have the same aperture at any focal length.<strong><br /></strong></p>

<p>I sold my tamron 28-75mm when I went full frame 5d thinking i'd replace with a 24-70, but ended up not liking full frame 5d and came back to a crop body.</p>

<p>Lynn, I'm wondering why you didn't like the full frame camera. I'm making a decision now, needing a 2nd body and thinking I'm going to stay with the crop sensor but considering going with a full frame. I'd like to hear why you went back to the crop sensor.</p>
