    Cool Some old and new lens comparisons ...

    The list is long and ... notable: The oldies but goodies

    Minolta AF 35-70mm f/4 MACRO
    SONY AF 18-70mm f/3.5-5.6 DT
    "Kit lens"
    TAMRON Powermaster AF 28-200mm f/3.8-5.6
    The center lens, KM AF 24-105 f/3.5-4.5 "D" was in need of repair and its results have been deleted
    TAMRON AF 28-300mm f/3.5-6.3 XR Di LD Aspherical (IF)
    TAMRON AF 18-250mm f/3.5-6.3 XR Di LD Aspherical (IF)
    TAMRON SP AF 28-75mm f/2.8 XR Di LD Aspherical (IF) MACRO


    The class of glass ...

    This thread will run in six parts ... at three different focal lengths for resolution (35mm, 50mm, 70mm) at a distance of 7-feet for the entire series.
    Camera is tripod-mounted with a electronic release. Lighting is from four overhead incandescent (Tungsten) 75W Floods.
    The actual focal length is a bit imprecise, as I used marked measurements indicated on each lens barrel.
    Each image is a crop from the original without any scaling or resize.
    Bear in mind that some lenses will not support f/4 at certain focal lengths ... and there will be a difference in the brilliance as we go long ...
    I have noted the aperture changes in parenthesis (f/ ...).
    This test took 2 & 1/2 hours for shooting and postprocessing, after set up of target and tripod.

    YOU DECIDE!

    First, the 35mm shots, at the widest available aperture (keeping it roughly @ f/4) for the lens, simulating a low light light shot (in the order listed above):

    Red face

    Personally ... the Minolta 35-70mm f/4 stays in the bag in preference to the almighty 28-75mm f/2.8 ... and just look at the results from
    the 18-250mm f/3.5-6.3 All-in-one! Man, that is impressive for a "utility" lens.

    Anyway folks, take your time and examine these ... and chime in with your own thoughts. It is a fair shake ... and I think I have made my point.

    Don I understand the purpose of the excersise, nice work thanks for the time and effort laying it out. the 18-250 does do the job across the board doesn't it. Now maybe it's just me and my untrained eye but I really like the images from the KM 24-105 in all the shots BUT the 35MM? but I can't tell you why I didn't care for the 35mm image? looking at the other shots and the KM 24-105 is that a display of 'Minolta color' and is that a good thing to see from the lens in this comparrison?

    Sean ... you cannot be serious. The KM put out some of the most god awful resolution I have seen ... except a couple other lenses.
    Something is just not right about it ... and I will have it checked, probably submitting it with my 24mm and 28mm primes for adjustment.
    I suspected it being poor, after my trip to Dubuque, IA, to see Sarah! After this little test effort ... I am hiding it, until I get 'er fixed.

    (EDIT: KM AF 24-105mm f/3.5-4.5 "D" was found to be damaged and unrepairable, due to a lack of replacable parts by SONY. The results
    it turned in were deleted and should not be considered viable or a reflection of what a new lens of its kind will do.)
