Canon 24-105/f4L-IS vs Tamron 28-75/f2.8

I'm considering swapping lenses around for my 20D - here's my proposal:

Keep:
Canon 17-55 kitty (just 'cuz)
Canon 70-200mm f/4L

Sell:
Tamron 28-75mm f/2.8 and
Sigma 50-500 (Bigma)

Buy:
Canon 24-105 f/4L IS

Future:
something wide - say 10 or 12mm on the wide end

Any comments/advice? Here's my thoughts...

I love the Tamron but the L is slightly wider and has IS. Is it worth swapping these 2 lenses as my main walkaround glass? Does the IS make up for losing the f2.8 speed?

The Bigma is a very nice lens but doesn't fit into my shooting style.

The kit lens isn't great and it really isn't wide enough either so I would replace that next with a 10-22 or something similar.

Of course I could just sell the Bigma, keep the Tamron and get something wide now...but the 24-105 is tempting me...:rolleyes

    Hey DJ,

    As you know from another thread, I am also pondering the lens lineup now. FWIW, I have never missed IS on the Tamron, as it is both fast and light weight. I also really like the 2.8 for night and indoors shots or when it's time for some really narrow DOF. I also like the short minimum focal distance. The extra 4 mm on the wide end wouldn't do much for me, but an extra 30 on the long end sounds really convenient. Maybe the IS would be more important on the long end. I guess the answer to your question is the same as to mine: "Well, it all depends..." rolleyes1.gif

    That Bigma could start getting a complex if it gets passed around too much more.

    For those that may be interested, that particular copy is very sweet.

    In response to your question about IS make up for loosing f/2.8 - remember, IS doesn't stop action. So, if you are shooting in a low-light situation, all the IS in the world will not eliminate blur caused by subject motion.

    Good thoughts guys, thanks. These choices are never easy - unless the budget is unlimited!

    The 24-105
    DJ,

    I had purchased the 24-105L prior to going to Kuwait. This lens is fantastic, very versatile and covers the range for 90% of my shooting situations, built like a tank and image quality is superb. Yes it has a stop less then the 24-70 f2.8L, but unless you need the shallower DOF or shooting a lot of indoor shots, the second generation IS is SUPERB, the lens is smaller then the 24-70 and has a bit more reach.

    For the dislikes.... it vingettes just a bit and has noticeable distortion at 24mm. Small gripes, but very acceptable for it's inherent range, although image quality is excellent wide open.

    My 2 cents worth.

    Andy, in that gallery you describe that picture as being a sample of the bokeh the 24-105 can produce....that's not bokeh, that's something else (DoF effect or something I guess). Bokeh would have to have out of focus light sources in the background like this http://Davidson.smugmug.com/photos/74312530-L.jpg (all those little circles are the bokeh).

    Yes, I'm nitpicking.
    Ok, but to further the point you were making, I think people forget that 105mm f/4 has less depth of field than 75mm f/2.8.

    Bokeh, is the quality of the out of focus areas, Richard. Sure, it can be how the specular highlights are,

    but it can also be this:

    Andy, I was kidding...see...get it? headscratch.gif :uhoh 11doh.gif
    I think I should delete my post and then you should delete this one that I am replying to so that there will be no record of my stupidity.
