    A guy in my town is selling a bunch of shit and says he'll let a 2X Tamron AF TC go for 50 bucks. Now, I don't expect this thing to be tack sharp but if it works decently stopped down it would be nice to have in my bag. Also, does anyone know if the 70-200 f2.8 L IS will retain focus with this thing on a 30D? Any help would be great. Also, it's not the SP (white) converter. :dunno:

    i use both the tamron 1.4x and 2x... i use the 2x sparringly, but the 1.4 works awesome. only thing is that it is non reporting. Nothing really different in image quality when compared to all other tc's

    go here for comparison...

    Cool, thanks for the link. I have been doing some more reading on these things. As with most TCs the results are skewed all over the place online. Some love them, some hate them. BH and other say the 2X will autofocus on F2.8 lens as long as there is plenty of light and contrast. Anywho, we'll see how it works when I go look at it. For 50 bucks, it's worth looking at I suppose.

    30d will autofocus just fine with it f5.6 will be your minimum ap, in sunlight you will love it, indoors ehhhhh you will hate it. 40d will focus great with it indoors or out on center focus point, and then outside focus points are iffy indoors.

    also please remember your viewfinder will be substantially dimmer. 2 stops dimmer

    I have the tamron 1.4x that I use on my sigma 70-300 ($180 lens)

    It produces some good pictures at f/11, but its hard to keep the shutter speed up high enough

    Here is one at 420mm, f/11, ISO 800, 1/250

    probably would be clear without the motion blur

    thats what I was thinking too.

    Im not sure which other pics I have that were taken with the 1.4x, the exif data just says what the lens is set at, and doesnt take into account for the converter

    I've used my Tamron 1.4x pro a few times but not as often as I thought I would

    I think i'm going to buy one. I didn't realize it was the same as the Kenko. I'm going to buy one to pair it with my 80-200 f/2.8
