I just bought ....
.... a Canon 28-135 IS f3.5-5.6 zoom for my trusty 10d. I had been targeting a 28-105 f35-4.5 zoom - but this one came up at a good value level so I took it. The zoom shipped from Tornonto yesterday - and I am egarly awaiting its' arrival. I had a gap in my coverage as all I had previously was a 20-35 f3.5-4.5 and the 70-300 IS F4-5.6.
Part of my thinking is I might sell the 70-300 IS and get a 70-200 f2.8 or the IS version. The L lense will be bulky and heavy - but the 28-135 will become my carry around lense. And some day I'll possibly drop the 20-35 in favor of the 17-40 f4 L.
Any thoughts? .... yeah ... I know ... half the crowd is gonna say I should have bought the Sigma 18-125.
Remember,
i had experienced wierd focusing performance with my Tamron 18-200 f3.8-6.3. And the Photozone reviews warned that their sample sufferred the same or worse effect with wierd missed focus performance. So - I am of a mind to avoid non-Canon lenses. Plus there is significant distortion and some vignetting in the Sigma. Otherwise, the Sigma is a sharp lense.
Otherwise... any thoughts?
BY the way.... does anyone know what the resolving limit is on a 6 or 8 mp sensor when it compares to the LW/PH (Line widths per picture height)? I think it means that near 1800-2000 a lense in this range exceeds the resolution limit of an 8MP sensor. Does this make any sense?

NOTE ... that the "Budget" disposable on the right above doesn't even have a FLASH to fail! So what's left to break or fail now?

try using superglue to avoid zoom creep... or any type of zooming function whatsoever.
