The User’s Review: Canon Zoom Lens EF 28-105mm 1:4-5.6 vs. 28-90mm 1:4-5.6 III



Similarities: 1:4-5.6; midrange zoom from 28mm; macro; plastic mount; 58mm filter; similar size when fully retracted.


Differences: 

EF 28 – 105 mm
EF 28 – 90 mm III

Sealed on the barrel
Move with internal barrel



Conclusions: I prefer the 28-105mm zoom. It has 1) a wider zoom range, 2) internal focusing (lens length will not change with focusing), and 3) sealed rear end to avoid dust into the barrels from this end.
