Sharp Wide-Angle Lenses for the Canon 5D

Monday, October 16th, 2006

Let’s take a look at discussions on the use of the Canon 5D in wide- to ultra-wide angle photography, and recommendations on suitable lenses, accessories and other equipment.

Head over to this interesting thread where Matthew requested for recommendations for sharp, wide-angle lenses to be used in tandem with the Canon 5D.

A summary of the candidate lenses:

Canon EF 16-35mm f/2.8L USM and Canon EF 17-40mm f/4L USM
, provided they’re stopped down to f/11

Sigma 12-24mm f/4.5-5.6 EX DG ASP HSM

A very long list of prime lenses: (note the emphasis on optical rather than build quality):

  • Sigma 20mm f/1.8 EX ASP DG RF
  • Sigma 24mm f1.8 EX ASP DG Macro
  • Sigma 28mm f1.8 EX ASP DG Macro
  • Canon EF 20mm f/2.8 USM
  • Canon EF 24mm f/1.4L USM
  • Canon EF 24mm f/2.8 – a bargain
  • Canon EF 28mm f/2.8 – another bargain wide-angle lens
  • Canon EF 35mm f/2 – the best ever wide-angle prime lens from the Canon stable
  • Here are some positive remarks about the Sigma 30mm f/1.4 EX DC HSM lens.

Getting rid of the dust on your Canon 5D viewfinder / prism

Saturday, October 14th, 2006

If you’re facing the issue of visible dust in the viewfinder of your Canon 5D (not to be mistaken with dust on the CMOS sensor), read this superbly detailed cleaning procedure (complete with pictures) which can eliminate or reduce the amount of that dust – also don’t forget to read the minor correction to the procedure.

Read this to get an understanding of the technicalities behind the source of the dust problem, which interestingly does not occur in other Canon Digital SLR cameras such as the 1DSmkII, 20D and 30D; the occurrence seems to be unique to the 5D.
