Sony SAL-24105 24-105mm
I am thinking about buying one and would like any feedback, good, bad and the ugly.
Sony SAL-24105 24-105mm f/3.5-4.5 Aspherical Zoom Lens for Sony Alpha Digital SLR Camera
Sony Alpha A700
Lens Bad Sony 18-70mm f/3.5-5.6
Yemen - Sanaa
I have nothing on this lens ... and I am reluctant to invest in it as a walk around, compared to the results I've been able to acheive with the TAMRON SP AF 17-50mm f/2.8 XR DiII LD Aspherical (IF)
I had a TAMRON SP AF 28-105mm f/2.8 LD for the Canon EOS 20D, but it was kind of heavy (32 oz), due to all the glass involved. The 17-50 only weighs 16 ounces, so it is a light carry, but the SONY 24-105mm weighs only 14 ounces, so that's a wash.
What you will miss is the wider focal length ... 24 equates to about 35mm, on a full frame camera, whereas the 17mm is roughly 28mm, the standard wide angle shot. Personally, I like that wider stuff, walking around. The base aperture of f/2.8 throughout the focal length also makes indoor shooting a bit nicer, as far as coping with standard lighting. f/4.5 tends to be a little too dark to use and you will begin to see noise, if the lighting is not adequate.
Good luck with your decision :)
