    During this entire episode, there has been a distrubing vagueness to everything that has been presented.
    What I am saying is: No real answers. I suspect we will ALL get answers we never anticipated, in January,
    as "the machine" gets going and the truth becomes evident.

    I have to ask myself: "Why do I sense ...?" Acch, it must be the time change. Yeah, that's it.

    It’s an ObomaNation!

    What worries me the most is Prime Minister Nancy Polocy, oops I mean Senator Nancy Polocy in charge of our NEW Democratic Congress (or is it parliament).

    Hope you guys don’t mind another voice in your Sony Forum.

    Cool Long look at infinty focus

    My disappointment with the Minolta AF 24-105mm f/3.5-4.5 "D" results is palatable. This was not what I had hoped at all.

    I will do a side-by-side, later this week ... putting the TAMRON SP AF 28-75mm f/2.8 XR Di LD Aspherical (IF) MACRO up against the Minolta AF 24-105mm f/3.5-4.5 "D" and range them out to thirty feet, instead of my usual indoor ten-foot shot. It was infinity focus where things really fell apart and I had not anticipated that.

    The SIGMA AF 10-20mm f/4-5.6 DC EX also seemed to be soft, out that far. Not quite as bad, but still annoyingly noticeable to me. I do not have an alternative to that lens, without losing the UWA aspect of the shots. My next widest lens available is the Minolta AF 16-35mm f/2.8-4 "D" and that's only a UWA on a SONY A900.

    A closer look at far away, you might say. Perhaps not. LOL

    Anyway, with a bit of a crop ... this one, turned out to be the best, in my opinion.

    Cool Lens Side-by-sides

    Okay, today ... under a rather lackluster sky ... before the rain, I took a couple of shots, using infinity focus on the TAMRON 28-75mm f/2.8; the Minolta 24-105mm f/3.5-4.5; and the TAMRON 28-300mm f/3.5-5.6 (in that order)

    Now, these are all 100% crops, taken in AUTO Mode ... to allow "Mr. SONY in the camera" to decide the settings, rather than my interpretation of it.

    Interesting Don I think #1 looks like it is the 'best' overall image, got to love that 2.8 glass. Maybe its just me and my tastes, or maybe my monitor, but i like the colors in #2 the best, intersting that the reflections are much more obvious in #2 then the other shots? all 3 shot 'naked'? #3 um well looks like pictures that I take, and I know I am trying to do netter LOL

    Yeah ... all three shots were through circular polarizers. The first and third were with the notorious SUNPAK CPs ... and the Minolta (second) shot was through a Hoya CP. Obviously, it makes a big difference in the color and reflection sharpness/detail. Thanks for noticing, Sean.

    What I was trying to "expose" was for the focal sharpness of each lens, at close inifinty ... but, I will try to shoot a series where each of the lenses uses the Hoya CP ... and leave the SUNPAK CPs out of this. Heck, I may just box them up and shelve 'em, after this test result! They really tended to kill the vivacious result. It is just amazing how these little filters can screw up a perfectly good focused shot.

    Unfortunately, I do not have a Hoya-filter for 67mm lenses, just TIFFEN and the SUNPAK CPs. TIFFEN is not a bad one, I use it on my 200-500mm lens ... and I will test it in comparison, in short order, to see if I need to pop for another $90 uplift to my CP selection. Then again, I could always PUNT and use the 77mm Hoya CP (through use of the step-down rings), that I currently have for the T70-200mm f/2.8 lens. It is a low-profile CP for use on the 10-20mm, when needed and has no from filter screw threads, so no traditional lens cap. I have to use a push-on cap to cover it.

    Ah well ... so much for budgetary shooting. When it comes to photography, I am finding out there is no such thing! It takes money to make honey! A $90 filter ... does a crackin' job over a $45 one.

    Cool Political Observations ... no, manufacturers, not politicians

    My question to myself is: What do I currently have that will offer an equal spread of image quality across the broad focal lengths, so that when I change lenses ... I effectively get the same thing?

    While in Dubuque, earlier in the week, before the USA’s youth decided to go “Socialist”, I, at least, had a chance to photograph Sarah Palin, at the GOP Rally.

    I brought four lenses, which I felt would give me a broad spectrum of shots and soon found that a couple just did not deliver “the goods.”
    1. TAMRON SP AF 200-500mm f/5-6.3 Di LD
    2. TAMRON SP AF 70-200mm f/2.8 Di LD MACRO
    3. Minolta AF 24-105mm f/3.5-4.5 “D”
    4. SIGMA AF 10-20mm f/4-5.6 DC EX


    The Minolta AF 24-105 f/3.5-4.5 "D", low-light and under 20 feet seems to be all you would want for a walk-around lens. But, once you creep out to infinity focus, it gets noticeably soft. No matter what focal length I used … it was not sharp.

    The SIGMA AF 10-20mm f/4-5.6 DC EX also tended to show this weakness … and being a wide-angle … infinity focus, to me is more important than close-up (but, hey, I really would like both). I just happen to like those “one-shot” Vistas at 10mm.

    I am planning on taking a number of test shots, later, to confirm the unimpressive results I got from the GOP Rally with the two lenses. While most of the images were better, compared to P&S cameras … coupled with the 200-500 and the 70-200 … uh, nope. I cannot marry the sets together, seamlessly.

    It is my sincere hope that the TAMRON SP AF 28-75mm f/2.8 XR Di LD can return better results, overall, as a suitable replacement to the Minolta AF 24-105mm f/3.5-4.5 “D” in my bag. I am dreading the idea that I will have to go to the SONY CZ 24-70mm f/2.8 to turn out comparatively similar results to the LONG zooms.

    Normally, I am an ALL TAMRON shooter ... with a few exceptions. I wanted to try and give the competition a chance ... and wound up a little disappointed. Also, I should note that I rarely take the same subject with four different lens ranges, from the same position, so this offered a rare look at the image quality and compare them. You can imagine how stunned I was to be leafing through the images and suddenlty be faced with an entire series that were ... glaringly softer than the others, on my monitor. Obviously, it is not nearly as noticeable on your camera's LCD screen. You would tend to think you've taken a decent shot and off you go. (It just ain't so!)

    In the past, TAMRON often packaged lenses under Minolta's logo ... for brand loyalty. As far as I can determine, the 24-105mm design is NOT one of those lenses. Minolta designed and manufactured this one, themselves. It is a far cry better than the AF DT 18-70mm f/3.5-5.6 "kit lens", so as an alternative, it is nice. I just need better infinity focus out of them.

    Anyway, just some optical observations I have made recently. YMMV
