    Hi folks,
    I have a Minolta Maxxum 7D digital SLR.
    I have 4 lenses from my Minolta Maxxum XTsi 35mm camera that I use with the
    7D. Three of these lenses are Minolta brand (24mm, 28-80mm and 100-300mm)
    and one is a Sigma lense (28-200mm).
    Of these lenses I like the 24mm fix lense the best. The 28-80 is a cheap
    lens that came stock with the XTsi. I don't care for the 100-300 zoom as it
    has a power manual fucus. The Sigma 28-200 seems to be a decent general
    purpose lense but doesn't seem to do a great job at focusing to infinity
    (even with a tripod).

    So what I'm looking for are some opinions on the best general purpose
    lense(s) I should be looking at for my 7D. I want a good quality, fast lense
    that is known to work well with the 7D. Then if I don't get good results, I
    only have myself to blame. I'd prefer a zoom lense that will give me the
    most versatility and not require a case for of lenses everywhere I go, but
    am open minded enough to consider using fixed focal length lenses instead.

    Any constructive advice would be appreciated.

    Joe

    Why not take you 7D into the local shop and ask to try some, take the
    results home and have a look for yourself.

    If you want to keep the cost down a bit apparently the Sigma 18-200mm is
    reasonable and worth a look.

    K/Minolta is coming out with three new lenses made specifically for
    their digital cameras (Dynax/Maxxum 7D,5D) . I haven't been able to
    find any for sale yet and K/M has not answered my request for sales
    info. Anyhow the lenses are:
    AF DT 11-18mm f/4.5-5.6 (D)
    AF DT 18-70mm f/3.5-5.6 (D)
    AF DT 18-200mm f/3.5-6.3 (D)
    You may want to wait and check these lenses out.

    I am curious about your comment that the 28-200 will not focus to infinity.
    Is this with manual or autofocus?
    Have you made exposures comparing manual and autofocus and at different f
    stops?
    You may feel that the 24mm lens is the sharpest because it has the greatest
    depth of field because of its shorter focal length.
    What I am getting at is that if all your lenses are underperforming then
    something may be wrong with the way you are using the 7d or with the camera
    itself. You may not have the world's sharptest lenses (who does?) but the
    lenses you have listed should all be reasonably adequate performers, in
    terms of apparent sharpness, with the 7d, possibly better than with film
    because the digital sensor only sees the central part of the image circle
    made by the lens.
    You really should evaluate theses issues before spending money on new
    lenses.

    Congratulations. A great camera.
    Just crack open your wallet as follows:

    Maxxum 28-70 f/2.8 G (or the new 28-80 f/2.8 G D) -and-
    Maxxum 80-200 f/2.8 G (or the new 70-200 f/2.8 G D, etc.)
    Maxxum 100 f/2.8 macro -or-
    Tamron 90mm f/2.8 macro

    If you're goung to be doing a lot of portraits, then consider the 50mm
    f/1.4 or 85mm f/1.4. (Even the modestly priced 50 f/1.7 should do well
    for most portraits.) You can do portraits with the 28-70/80 with great
    care to keep the camera level/square wrt the subject, but your error
    rate (poor perspective related distortion) will be higher.

    Personally, I'm thinking of adding the Maxxum 17-35 (either the f/3.5
    "G" version, or the Tamron (badged Minolta) f/2.8 - f/4 (D) version).
    Or a Nikon Coolscan 9000 and used RZ67. Or... <sigh> Whatever, I need
    an MF camera by September and the scanner to read it.

    My SO has the 28-200 (Sigma) and she works hard with it to get very good
    results (Maxxum 5). But I also know when she uses the 50 f/1.7 that she
    gets great reults that exceed the Sigma in contrast and color.

    Cheers,
    Alan.
