The Canon EF 75-300mm f/4-5.6 III USM Lens is a relatively small, very light and very cheap lens for this focal length range.
And the 75-300 III really is cheap. You usually get what you pay for - unfortunately this is the case with the 75-300 III.
Build quality of the Canon EF 75-300mm f/4-5.6 III USM Lens is mediocre (and this may be a generous rating). Lightness is the benefit, but you won't find smooth zoom and focus rings. I wouldn't want to subject the 75-300 III to a lot of abuse as I doubt it would survive.
Image quality from the Canon EF 75-300mm f/4-5.6 III USM Lens is also mediocre.
The 75-300 III is soft wide open at all focal lengths. Sharpness decreases as it zooms from 70mm to 300mm. However, the corners are softest at 70 and getting better by 300.
Corner and center softness decrease as the 75-300 III is stopped down.
Stopping down a relatively slow lens means a lot of light (or a flash) is necessary for handheld photos. Handholding a slow lens at 300mm requires a lot of light to begin with.
A 7-blade aperture is a decent feature for a lens in this price range.
The Canon EF 75-300mm f/4-5.6 III USM Lens is most comparable to the Canon EF 75-300mm f/4-5.6 IS USM Lens. Image quality is very similar between the two. Of course, IS can offset part of the handholding dilemma.
The 75-300 III suffers from CA (Chromatic Aberration). Pincushioning is visible at 300mm. Vignetting is well controlled. Focus speed is OK, but not fast.
