Canon EF 28-105 F/3.5-4.5 II USM

ef_28-105_35
Review Date: Sep 12, 2007 Recommend? yes | Price paid: $150.00 | Rating: 9 

 
Pros: Excellent IQ for the price. Small and lightweight. Good build. Quiet and accurate focussing. No zoom creep.
Cons:
CA clearly visible wide open, especially at the wide end.

Decent build quality for a consumer lens and a worthy poor-man's alternative to the 24-105mm. An excellent travel lens for a 5D (or even for a crop body if you can live with the relatively narrow field of view at the wide end).

Images are, as expected, slightly soft at f/3.5 at the wide end, particularly around the edges, but the lens sharpens up well enough by f/5.6. The longer end however is relatively sharp even wide open, and doesn't seem to benefit as much from stopping down. The USM focussing is quiet and accurate. Suffers a bit from CA but so do most lenses wide open.

It obviously doesn’t match the 24-70 or 24-105 in terms of colour and contrast but for the times you need a small and compact lightweight 'standard' zoom you could do a lot worse than the 28-105mm.


 
Canon EF 15mm f/2.8 Fisheye

Review Date: Apr 29, 2007 Recommend? yes | Price paid: $600.00 | Rating: 8 

 
Pros: Pretty good build quality. Quite sharp wide open, and it improves noticeably at f4 and smaller. Nice colour and contrast. A cute little lens.
Cons:
Front element is a nightmare to keep completely spotless. My 5D sometimes over exposures (when set to Evaluative). And if I was being really picky, no USM so AF is a bit noisy.

Sold my 17-40 to get this lens (my copy was sharp enough but with a max aperture of f4 it was just too slow and not wide enough for my kind of photography).

I'm very pleased with the Canon fisheye so far. For reference, mine was manufactured in Oct 2006. Being a fisheye, focussing is quick despite the lack of USM. It seems to suffer from a bit of CA in high contrast compositions (e.g. tree branches set against a bright sky) but otherwise can't really fault it. It's very sharp, even wide open.

Just make sure you don't lose the lens cap!
