Wide-angle prime for Canon?

    I am just learning to take pictures and decided to buy the second lens
    (the first being Canon 50/1.4). I want it to be wide-angle, suitable for
    street photography and landscapes (right now I am taking pictures with
    Canon EOS 50, but I don't want to invest in a lens that would be
    completely useless with digital camera with factor 1.6). The two likely
    candidates are:

    1. Canon EF 24mm f/2.8
    2. Sigma 24mm f/1.8 EX DG Aspherical Macro

    What do you think about these lenses? Does Sigma's 1.8 warrant having to
    carry heavier and bulkier lens? What are other alternatives?

    1. Canon EF 24mm f/2.8
    The Sigma 'DG' lens is designed for DSLR , I'm not even sure it can be used
    on a 35mm SLR. Being designed for digital I would say that the performance
    would be poor if it can at all be used on a film body. You're using a Canon
    body, use Canon lenses on it.

    I have the Canon 24mm f/2.8 that I use on my Rebel XT. Very nice lens, good
    bokah, good optics, internal focusing, light, small and uses 58mm filters.
    Downside...try to get a used one for a decent price!

    I like to use a small inconspicuous lens for street photography.

  5. You're thinking about the 'DC' lenses, which only cover up to APS-C sized
    digital sensors. They won't cover full 35mm frame and are not designed
    for use with film cameras. However, the 'DG' lenses do cover 35mm and
    perform well with film, but have increased edge illumination to make them
    better performers when used on DSLRs.

    Does Canon offer a pancake lens like Nikon and Pentax? The Pentax lens
    is awsome for "inconspicuous" & pretty good optically.

  7. The Sigma's a pretty big hunk of glass. Don't know if I'd want to carry
    it around my neck all day. Unless you absolutely need the f1.8 aperture,
    I'd go with the Canon. Better glass, anyway.

  8. Some really odd advice on this thread. Sounds to me like people are writing
    without experiencing.
    The Canon f/2.8 is no match for the Sigma f/1.8 and the Sigma's still a
    small, light lens compared to a zoom. The Sigma's sharper, it vignettes
    less, its barrel distortion is negligible for all but commercial
    architecture. Its corner sharpness is good and CA is very low for a WA. Best
    of all is its close focusing ability coupled with the very usable wide
    aperture: Its bokeh is excellent when used this way and specular highlights
    maintain a neat circular aspect. This is the only non-Canon lens I use and
    that's because it really is very significantly better optically and much
    more versatile than the Canon f/2.8. BTW, my main camera's a 5D which is
    very unforgiving with WA's: The Sigma's performs much better than any other
    WA I've tried with this camera (incl. L zooms at 24mm).

  9. No. I have the Pentax pancake, and it's far slimmer than the smallest EF
    lens I've tried. (EF28 f2.8, 35 f2, 50 f1.8 [both] )

    You might also consider the Canon 2.8 20mm prime. Still fairly wide even
    later when you make a digital switch, reasonable price, good optics,
    unobtrusive. If you only are working with two lenses, there is not a great
    spread between 24mm and 50 mm.

    I have an old Nikon 55/3.5 Micro Nikkor that changes the aperture
    automatically - using a cam - as one focuses closer for macro work.

    I'm wondering if the Canon manual-focus 50/3.5 Macro SSC FD BL does
    this as well.

    I'm also wondering if either of these lenses "double compensates"
    when used with TTL metering.

    In other words, the lens opens up with the cam AND the meter sees the
    relative aperture change so compensates again.

    Any advice appreciated.

    I wouldn't go that far...there's a hell of a difference between a 50mm
    and a 35mm on a 35mm film camera. Might not be so much on a digital
    with a "zoom factor" involved.

    I use 24, 28, 35 and 50mm as well as some telephoto lengths and I can
    tell an appreciable difference between all of them.
